Disable field on Click of Button in D365 CE using JavaScript.

Use Case – One of my requirements is to disable the field on click of button Reopen Project on Project form.

Let’s see how we can achieve this.

Solution –

• Create Web resource and add below function:

function markFieldsReadOnly(executionContext)
{
    try
    {
        var formContext = executionContext;
        formContext.getControl("cf_probonohoursnew").setDisabled(true);
        formContext.getControl("cf_probonohourvaluenew").setDisabled(true);
 
    }

 catch(e)
 {
    alert("An error occurred, please try later");
 }
}

• Create Solution in CRM which contains only a single entity on where we have button called “Reopen Project”.
• Open same solution in XRM Toolbox -> Ribbon Customization.

In Order to get form Context from Ribbon, Pass CRM Parameter – Primary Control

Select Library which is your web resource and add Function Name and publish.

Hope this helps!
