Step-by-Step Overriding Out of Box Command Behavior

Have you gotten a requirement to override a system ribbon or command button? If yes then this article will help you to implement your requirement.

Requirement: Let's say we have a requirement to prompt the user before saving the record and we need to save or cancel the save operation.

Solution: We can create a custom button to replicate the out-of-the-box button, we will be calling the same method that is called from the out-of-the-box button. Once our button is ready we will hide the out-of-the-box button. To implement our requirement use the following procedure.

Download and install the RibbonWorkBench solution.

Create a Demo solution and add an account entity to the solution.

Note: You can follow our previous article to get the RibbonWorkBench solution, to create the demo solution and add existing entities. We will override the Save button on the account entity.

Open the Demo solution and add a new web resource by navigating to Components ->Web Resources -> New.

Fill in the following properties and click on the Text Editor button:

Name: OnSave.js
Display Name: OnSave.js
Type: Script (Jscript)

At this point create a blank function as in the following and Save and Publish the web resource.

function OverrideSave()
{
//We will be changing it in later step
}

Now we will create a custom button and will copy the properties or save button. Using the following procedure:

Open RibbonWorkBench and select our Demo solution
Drag a Button from the Toolbox and leave it next to the Save button under the Form section
Right-click on the system Save button and select Customize Command
Copy all properties system Save button to our custom button except the Sequence and CommandCore properties (we need to copy and paste these properties one by one)

Now we need to check the command associated with the system save button and need to see which function and parameter is used for that. Use the following procedure.

Select Mscrm.SavePrimary under Commands and click on Actions lookup to check for function name and parameter, we got this command name from the Save button commandcore property.

Right-click on Command and select Add New, we need to add a command for your custom Save button.
Click on Actions lookup then click on Add and select JavaScript Function Action
Write our function name and select our web resource
Click on Parameters lookup then click on Add and select Crm Parameter
Select Primary Control under the Value drop down

It should look as in the following:

Select our custom Save button and select our command name under the command drop down
Right-click on the system Save button and select the Hide Button option
Click on the Publish button to publish your changes
Open our JavaScript web resource and change the function definition as in the following

function OverrideSave()
{//Capture response
var response=confirm("Do want to save ??");
if(response==true){
//system function
Mscrm.RibbonActions.saveForm();
} }

Save and Publish web resource and open any account record. Change some field value and click on the Save button, you should get a prompt as in the following:
