ItemCommand's e.Item.ItemIndex always 0

[Paul J]

I have a radGrid. I have a GridButtonColumn for a delete button. when the delete button is pressed, it brings up a rad confirm box via the following method:

http://www.telerik.com/community/forums/aspnet-ajax/grid/need-dynamic-confirmtext-on-programmatically-added-column.aspx

the radconfirm box works fine. it shows the right text and everything. the confirmFn gets the correct itemIndex value as well. but once the process hits the codebehind's ItemCommand event for the DeleteMember CommandName ItemIndex is always zero.

So when OK is clicked (in the radWindow), it continues on to the radGrid's ItemCommand event. Once it goes into this event it claims the e.Item.ItemIndex is 0 (first row in grid), even when I've clicked on a row that is definitely not 0 index.

this has been driving me crazy. I'd like to get it resolved ASAP. any help is appreciated.

my code:

javascript code for the confirm box:

<script type="text/javascript">
        function confirmFn(text, itemIndex) {
           var callBackFn = function(arg) {
                 if (arg) {
                     var masterTable = $find("<%= rgMembers.ClientID %>").get_masterTableView();
                     masterTable.fireCommand("DeleteMember", itemIndex);
                 }
             }
             radconfirm(text, callBackFn);
         }


    </script>

help! thanks!

Well finally bothered to look a little closer to the e object and see there's a e.CommandArgument that does have the right index. I could have sworn though I've used the code before and the ItemIndex had the right value...and I didn't have to use the CommandArgument value.

hrmmm.

Hello Paul,

Verify that you pass the corresponding index of the clicked item (itemIndex) as a second argument to the fireCommand client method of the grid. Thus it will be available as second argument (e.CommandArgument) in the ItemCommand server handler of the grid.

e.Item.ItemIndex will default to 0 in this case because you raise custom command through MasterTableView's client object method, not a particular row in the grid.

Best regards,

Thanks for the info!

[Mike]

Can you provide sample code for passing the extra arguments?

[Paul J]

Mike, what fixed my issue was changing the following line under my "DeleteMember" case of my radGrid's ItemCommand event from:

ApplicantID = CType(rgMembers.MasterTableView.DataKeyValues.Item(e.Item.ItemIndex)("ApplicantID"), Integer)

to:

ApplicantID = CType(rgMembers.MasterTableView.DataKeyValues.Item(e.CommandArgument)("ApplicantID"), Integer)

hope this helps.

Paul J...thanks much for the reply, but I still have a problem.  I can't figure out when to pass the CommandArgument from?

My setup is this...Radgrid with 3 columns, one of them being a "GridClientSelect" column so that users can select a row.  Once a row is selected, I enable various buttons on a radToolBar which is sitting in the CommandItem of the radGrid.  I currently have a "CommandName" set for each button on the toolbar so that when the event bubbles up to the ItemCommand I can determine which button was pushed in my code-behind, but I don't know where to set the commandArgument. 

Thanks again for your help, I'm sitting here pulling my hair out!

Mike, you better post your code. I am not totally understanding your setup. Also, if a telerik support person chimes in, I'm sure they'll request to see it as well.
