How to get column name from filter template control's JS event?

[Adam]

Hi,

I currently have a couple of RadDatePickers in a GridBoundColumn's FilterTemplate section.  I'm using the ClientEvents-OnDateSelected on both RadDatePickers to call a JavaScript function.  

ClientEvents-OnDateSelected="DateSelected"

function DateSelected(sender, args) {
   ...
}

In the JavaScript event that's called by the RadDatePickers I need the name of the column that the RadDatePicker which called the event is in.  Any idea how I can get this?

Cheers,

Adam

In my example I am extending the GridBoundColumn class and the following solution works for me:

I added a custom attribute to the RadDatePickers called "ParentColumName".

fromDatePicker.Attributes.Add( "ParentColumnName", this.UniqueName );

I pick this up in the JS event as follows:

var parentColumnName = sender.get_element().parentNode.getAttribute('ParentColumnName');

I can then use the column name to fire off this particular column's filters etc.

Is there any in-built solution by Telerik?

No idea, dude. This solution worked for me so I stuck with it.

Hello Rajan,

Since this is a control within a template (the FilterTemplate), RadGrid could not have any control over the content of that template, which is the reason that there could not be a built-in way for retrieving the column name from within a client-side event of the filter control. However, the approach that Adam is using is simple enough and should help you achieve the desired result.

Thanks Konstantin. Adams post helped me. However I was just curious to know if there is alternate solution.
