Dear Telerik Team,

When I tried the following code,the whole page disappears.

 protected void RadGrid1PreRender(object sender, EventArgs e)
    {
        
                if (Condition) 
                    RadGrid1.ClientSettings.ClientEvents.OnRowDblClick = "true";
                else
                    RadGrid1.ClientSettings.ClientEvents.OnRowDblClick = "false";*/
    
    }


Thanks in advance.

Hello Aewin,

I tried the same scenario in this version 2011.1.315.35 and it worked as expected. Also try populating the grid with Advanced Data-binding.Check the following documentation.
Advanced Data-binding (using NeedDataSource event)

Thanks,
Shinu.

Hi Aewin ,

Note that RadGrid1.ClientSettings.ClientEvents.OnRowDblClick is a property that holds the name of the event handler for the OnRowDblClick event and is not used to toggle row double click. So assigning value "true" or "false" based on some condition is inappropriate unless you have event handlers called "true" and "false". To achieve the desired functionality you could hook the event and check the conditions in it. If they are not met  cancel the event by executing the following command: eventArgs.set_cancel(true) otherwise you could do your custom logic.

I am also attaching a sample project to illustrate the recommended approach.

function

 

 

RowDblClick(sender, eventArgs) {

 

eventArgs.set_cancel(

 

true);

 

 

 

}

looks like setting this code is not working. Any other ideas!.

Hi Emmanuel,

Could you please try to use return on given condition met?

I have created a sample RadGrid web site where alert is fired only on double-clicking the rows with even index number. On my side everything works as expected and the suggested approach successfully cancels the RowDblClick event on odd rows. Please check out the attached application and let me know if you need further assistance.

All the best,
