Dynamics 365 v9.0 – Set Multi-Select Option Set values using JScript

Hello everyone,

In my previous post on Multi-Select Option Sets , I mentioned about setting multi-select option set values using setValue() method overwrites existing selected values. In this post I would like to discuss more on that and how we can append or remove certain values using simple JScript methods.

getValue() / getText()- Returns Array

function SetMultiSelValues(executionContext) {
//Get Form Context from Execution Context
var formContext = executionContext.getFormContext();

//Get Array of Selected OptionSet Values
//Returns: [100000005, 100000001]
var selectedValues = formContext.getAttribute("new_multiselect").getValue();

//Get Array of Selected OptionSet Text
//Returns: ["Six", "Two"]
var selectedOptionText = formContext.getAttribute("new_multiselect").getText();
}

setValue() – To Overwrite existing Values

Args: Pass integer or Array of integers

function SetMultiSelValues(executionContext) {
//Set Value a Single Value - Overwrites Existing Selected Values
formContext.getAttribute("new_multiselect").setValue(100000005);

//or

formContext.getAttribute("new_multiselect").setValue([100000005]);

//Set Multiple Values - Overwrites Existing Selected Values
formContext.getAttribute("new_multiselect").setValue([100000003, 100000004]);
}

setValue() – To Append to existing Values

Here I am using concat() JScript method to concatenate existing and new values

function SetMultiSelValues(executionContext) {
//Get Form Context from Execution Context
var formContext = executionContext.getFormContext();

//Get Array of Selected OptionSet Values
//Returns: [100000005, 100000001]
var existingValues = formContext.getAttribute("new_multiselect").getValue();

//Append a set of values
var newValues = [100000003, 100000004];
var updatedValues = ConcatArrays(existingValues, newValues);

//Appends to Existing Selected Values
//New Values: [100000005, 100000001, 100000003, 100000004]
formContext.getAttribute("new_multiselect").setValue(updatedValues);
}
function ConcatArrays(existingValues, newValues) {
if (existingValues === null || Array.isArray(existingValues) === false) {
return newValues;
}

if (newValues === null || Array.isArray(newValues) === false) {
return existingValues;
}
return existingValues.concat(newValues);
}

setValue() – To Remove List of Values

Here I am using JScript’s filter() method to remove values from selected option set values array


function SetMultiSelValues(executionContext) {
//Get Form Context from Execution Context
var formContext = executionContext.getFormContext();

//Get Array of Selected OptionSet Values
//Returns: [100000005, 100000001, 100000003, 100000004]
var existingValues = formContext.getAttribute("new_multiselect").getValue();

//Removes from Existing Selected Values
//New Values: [100000005, 100000004]
var removeValues = [100000001, 100000003];
updatedValues = RemoveFromArray(existingValues, removeValues);
formContext.getAttribute("new_multiselect").setValue(updatedValues);
}

function RemoveFromArray(existingValues, removeValues) {
if (existingValues === null || Array.isArray(existingValues) === false) {
return removeValues;
}

if (removeValues === null || Array.isArray(removeValues) === false) {
return existingValues;
}

return existingValues.filter(function (value, index) {
return removeValues.indexOf(value) == -1;
})
}

Hope it helps..!!

How – To Series 20: MultiSelect Option Set in Dynamics 365

1 Reply

Hello everyone,

Today i want to do a quick post about “MultiSelect Option Set”, one of the most awaited feature in Dynamics 365. It used be a frequent business need and we end up developing HTML web resource and N to N relationship with custom entity to provide required functionality.

I like the new control and its easy of use. There are quite a good number of blog posts talking about this new feature. However, I wanted to mention some of my observations about this new control.

MultiSelect Option Set allows maximum of 150 values to be selected. If we try to select more than 150 and try to save the form we will get following error.

2. We cannot set default vlaue(s) during the field customization.

3. setValue() method expects an array as it’s parameter and overwrites existing selected options. I know it’s too early to make a comment until SDK for v9.0 is released as we may expects to see some new methods specifically for MutliSelect Option Set control.

Thanks

Hi,
We all know that only OOB fields have been restricted from Field Level Security and all the custom fields can have Field Level Security. However, today i tried creating a new field of type “Single Line of Text” of format”EMail” with “Field Level Security” enabled.To my surprise I can see the following error:

And this is the error message in the Log file: “This field is not
securable”

I raised this issue with MSConnect here . Need to findout whether its bug or by design.

How To – Series 7: How To override(Enable, Disable, Show, Hide, Custom Logic) Out of the Box HomePageGrid ribbon elements – CRM 2011

Hope my earlier posts on Ribbon elements helps you. In this post we will see how to Enable/Disable Out of the Box ribbon elements in Dynamics CRM 2011. After going through the SDK, it seems there is no direct solution to override existing <CommandDefinition>. However, the documention says using <CustomAction> we can Add or Replace items in the ribbon. It gives me an idea to replace existing OOB(Out of the Box) ribbon item with Custom ribbon item and define our own <CommandDefinition> for that. At the same time we can also go with the OOB <CommandDefinition>. Lets see how we can do that stuff.

Lets consider “Edit” ribbon item on the “Account” entity “HomePageGrid”. I want to disable this “Edit” button when user selects more than one record in the sub grid(i.e I don’t want “Bulk Edit” feature for Account records). The same can be achieved with security roles. However, for the sake of simplicity and to focus more on how we can override <EnableRules>, <DisplayRules> and <Actions> for an OOB item I have considered this scenario.

Step 1:

Open “accounribbon.xml” file from the “sdksamplecodecsclientribbonexportribbonxmlexportedribbonxml” location in the CRM 2011 SDK.

Below is the definition for “Edit” button

Below is the <CommandDefinition> for “Edit” button.

</EnableRules>

</DisplayRules>

</JavaScriptFunction>

</Actions>

</CommandDefinition>

Copy both of the definitions and we gonna use them in the next steps.

Step 2:

Add “Account” entity to a solution. Export it. Open “Customizations.xml” file.

Go to <EnableRules> section and add following <EnableRule> which will return “true” when only one item is selected in the sub grid.

</EnableRule>

Step 3:

Go to <CommandDefinitions> section and add copied <CommandDefintion> form the Step1. Rename “Id” value to “Sample.account.grid.DisableExisting.Command”

</EnableRules>

</DisplayRules>

</JavaScriptFunction>

</Actions>

</CommandDefinition>

Add <EnableRule Id=”Sample.account.grid.OnSelection.EnableRule”/> to the <EnableRules> section.

</EnableRules>

</DisplayRules>

</JavaScriptFunction>

</Actions>

</CommandDefinition>

Step 4:

Add following <CustomAction> to the <CustomActions> section:

</CommandUIDefinition>

</CustomAction>

Here we need to carefully observe what we have done to replace existing “Edit” button with our own Custom Button.

Here I have given unique id for the <CustomAction> and for the “Location” attribute I have placed “Id” of the OOB “Edit” button only. I haven’t kept “._children”. This makes all the difference…

Here, I have given OOB “Edit” button “Id” as the “Id” for the new item. Do remember that, “Id” value in the <Button> should be same as “Id” value in the <CustomAction>. In other words the new Ribbon Item should have same “Id” as the OOB item.

For the “Command” attribute I am planning to use OOB Command that has been defined for the “Edit” item. I am planning to use OOB features and in addition to that I am planning to have my own <EnableRules>, <DisplayRules> and <Actions> rules. Feel free to use your own Command if you require to.

For remaining attributes also I wish to go with OOB except for the Images. Here I want to show images from my web resource.

Now, Import the solution with these changes to your system. Below is the result:

When no recod is selected:

When One record is selected:

When multiple records are selected

In this way we can override OOB behaviors and visualizations for OOB ribbon elements. If you want to have more complex queries for the <EnableRule> then we can use <CustomRule> to call a JScript function. Please see my earlier post here: http://howto-mscrm.com/2011/04/how-to-series-6-how-to-use-customrule.html on how to use <CustomRule> with “HomePageGrid”.

Hope it helps everyone. 🙂

How To – Series 6: How To Use “CustomRule” to Enable/Disable HomePageGrid Buttons- CRM 2011

In the earlier post here we have seen how to use <ValueRule> to retrieve a field value from the CRM form and Enable/Disable Custom Button based on that value. What if we want to do the same thing with “HomePageGrid” also like based on a particular value from the selected record in the Grid, Enable/Disable a Custom Button? Can we use <ValueRule> for the same?? The answer is big “No…!!!” Instead, we can use <CustomRule> wherein we can call a JavaScript function to do the required stuff.

For this post also, I am doing required stuff for “HomePageGrid” on top of the following SDK walkthrough: Walkthrough: Add a Custom Button to an Existing Group for a Specific Entity . Below is the result of SDK sample for Account Home Page Grid:

Custom button “Hello Ribbon” will be enabled when only one Account record is selected. Following is the code snippet for that:

</EnableRule>

Now, let’s consider a scenario where we want to enable the “Hello Ribbon” button when only one Account record is selected and the selected record should have “Fax” value. We will see what are all the steps we need to follow to accomplish this.

Step 1: Retrieve the selected Item’s GUID value

Step2: Use the resultant GUID value to retrieve “Fax” field value using “REST” or “SOAP” calls

Step 1:

Inorder to retrieve selected item’s GUID value, we can use the following:

The first one returns an array of GUIDs for the selected items and the latter one returns GUID of the first item in the selected items.

Using this one we can get a count of selected items.

Step 2:

Use <CustomRule> to call java script function by passing the selected GUID value and it’s count. Following is the code snippet to do that:

</CustomRule>

</EnableRule>

Here, “FunctionName” refers to Java Script method and “Library” refers to Java Script web resource. And the <CrmParameter> defined will pass it’s returned Value to the <CustomRule>’s function as parameters.

Let’s go define “IsExist” method in “new_CheckFiledValue.js” web resource as follows:

function IsExist(rowscount, firstselectedid) {

if (rowscount == 1) {

var ValueExist = ReturnValue(firstselectedid);

return ValueExist;

}

else {

return false;

}

Observe the “IsExist” function’s prototype. It has two parameters. The first one “rowscount” refers to first <CrmParameter> and the second one referes to second <CrmParameter>. In the definition, I am calling a method “ReturnValue” with “firstselectedid” as the parameter when “rowscount” is 1. If not, returning “false”. In the “ReturnValue” method I am planning to retrieve “Fax” field value based on the GUID from the “firstselectedid” parameter using REST based web service call.

function ReturnValue(firstselectedid) {

var context = Xrm.Page.context;

var serverUrl = context.getServerUrl();

var ODATA_ENDPOINT = “/XRMServices/2011/OrganizationData.svc”;

var ODATA_Filter = “/AccountSet?$select=Fax&$filter=AccountId/Id eq (guid'” + firstselectedid + “‘)”;

var jsonEntity = window.JSON.stringify(CRMObject);

$.ajax({ type: “GET”,

contentType: “application/json; charset=utf-8”,

datatype: “json”,

url: serverUrl + ODATA_ENDPOINT + ODATA_Filter,

beforeSend: function (XMLHttpRequest) {

XMLHttpRequest.setRequestHeader(“Accept”, “application/json”);

success: function (data, textStatus, XmlHttpRequest) {

var faxValue = data[“d”];

if (faxValue != null)

return true;

else

return false;

error: function (XMLHttpRequest, textStatus, errorThrown) {

return false;

}

});

}

This function returns “True” if “Fax” field has value else “False”.

PS: We need to refer “JQuery” and “JSON” libraries in our Java Script web resource to use REST end points. However, I am still struggling to find out how to refer “JQuery” and “JSON” libraries in our Java script web resource as we are not calling the functions as part of any event. Right now, I am working on an “Online” deployment. If it is On-Premise environment, we could easily call “JQuery” and “JSON” libraries as external files the same way we used to do in CRM 4.0. Anyways, I will come back here once I find a solution.

Hope it helps in giving a basic idea on how to use <CustomRule> and how to Enable or Disable HomePageGrid’s Button based on a condition.

How To – Series 5: How To Use “ValueRule” and “OrRule” in Ribbon Customizations – CRM 2011

Hello everyone,

This is my first blog post on Dynamics CRM 2011. I have been going through Dynamics CRM 2011 SDK and it has fantastic stuff to learn. I went through the Walkthrough: Add a Custom Button to an Existing Group for a Specific Entity Ribbon customization stuff in the SDK and able to do it. In that walkthrough, by using “CrmClientTypeRule” and “FormStateRule” rules custom button on the Form(not HomePageGrid) has been enabled only for “Web Client” and for “Existing Records”. This is the result of SDK sample:

Now, In this post I would like to add few more things on how to use “ValueRule” and “OrRule” rules with “EnableRules”.

Lets consider, if we want to enable the Custom button only when a specific filed on the form has a value. In that scenario, we can use “ValueRule” which can retrieve a specific field value on the form. Assume that we have to show Custom button only when “Fax” filed has value. In that case we can think of two approaches. One is, if “Fax” field is null then disable the Custom Button and the other one is, if “Fax” field has “anyvalue” then “Enable” the custom button. However, for ribbon customizations we have only “EnableRule”. And certainly “EnableRule” only works with “Equality” condition. So, In order to support different conditions we have one useful attribute called “InvertResult” which negates the result(Instead of looking for “not equal” condition, go with equal condition and use “InvertResult”).

Following the piece of code we need to place it under //RibbonDiffXml/RuleDefinitions/EnableRules/EnableRule/

Here I have used unique Id for the “EnableRule” which can be used to refer in the “CommandDefinition”. For the “ValueRule”, I have defined three attributes. “Field” refers to the schema name of particular field on the form from which we are trying to retrieve a value. “Value” attribute will hold user given value which will be checked against “Field” attribute’s value for equality. In our case, I decided to go with “null” check condition and “InvertResult”. So, I have given “null” as the value and for the third attribute “InvertResult”, I have given “true” as the value. Whenever “Fax” filed has value then the returned value from “ValueRule” is “True”(as we are using Invert Result) and “False” if it is “null”.

After placing above code, refer the id in the following location //RibbonDiffXml/CommandDefinitions/CommandDefinition/EnableRules as

Now, export the solution and publish it. Below will be the result when Fax doesn’t have any value:

And when “Fax” field has a value:

That’s cool. With single line additional code we can enable/disable custom button based on field value.

Now, I thought of checking with “Option Set” fields and want to whether it considers “Selected Value” or “Selected Text”. Certainly, it is “Selected Value” by default. Below is the piece of code I wrote:

And
<EnableRule Id=”Sample.account.form.CheckFaxValue.EnableRule”/>
<EnableRule Id=”Sample.account.form.CheckContactValue.EnableRule”/>

Below is the result:

When “Address Type” is selected as “Bill To(Value:1):

And when other than “Bill To” is selected:

This is fine and as expected. And one more thing we need to observe “EnableRule” placed under RibbonDiffXml/CommandDefinitions/CommandDefinition/EnableRules are by default uses “and” filter. If I remove “Fax” filed value and keep “Bill To” as the “Address Type”, the custom button will be disabled. Check the below screenshot:

So, what if we want to go with “or” condition??? Certainly, we do have “OrRule” which can be used for this purpose. Instead of having two separate “EnableRule” for each “ValueRule”, we can have one “EnableRule” with collection of “ValueRule” under “OrRule”. Below is the piece of code we need to have under //RibbonDiffXml/RuleDefinitions/EnableRules/EnableRule/:

And refer the “Id” at the following: //CommandDefinitions/CommandDefinition/EnableRules
<EnableRule Id=”Sample.account.form.OrRule.EnableRule”/>

Below is the result with “OrRule”:

Now, the question arises what if I have complex query and based on its result custom button should be enabled/disabled??? The answer is, we do have one more feature called “CustomRule” using which we can call a Java Script function and based on the result(should be Boolean) we can enable/disable a custom button. In this coming post I will show how to use that Rule and in which scenarios it will be more useful.

This post gives basic idea on how to use “ValueRule” and “OrRule” in Ribbon Customizations. Hope it helps…!!! J
