Hello Nilesh,

Currently there is no clientside events for charting. However, for your scenario, you can use OnAfterResponseProcess clientside events. There should be actionName parameter which you can use for your validation.

Handy,

Thanks for the response. Would you mind providing a sample for this event?

Hello Nilesh,

Sure, Here is my sample code. 

function WebGrid1_OnAfterResponseProcess(controlId, actionName, lastRequestObject, xmlResponseObject)
{
	var WebGrid1 = ISGetObject(controlId);
        var button=document.getElementById("Button1");
        if (actionName == "Charting") 
        {
                button.style.display = "none";
        }
		return true;
}
