ListBox not being found in EditForm

[Kyle]

I have a ListBox on my EditForm that is populated based on the CommandArgument from the ItemCommand. The data is being accessed, but when I go to add the data to the ListBox, the control isn't being found. Here's what I have: 

if (e.CommandName == "Edit") {
                GridEditFormItem item = (GridEditFormItem)(e.Item as GridDataItem).EditFormItem;
                ListBox lb = (ListBox)item.FindControl("lstMembers");

the ListBox is null, the control is named "lstMembers" (I already checked that) my suspicion is something in the previous line of code. When I put the same two lines in another block (different command name) it works fine, so I think it might have something to do with the fact that the control itself isn't loaded yet. Can someone confirm/clarify this for me, and if so give me a work around?

the listbox isn't in the item - it's actually in a table cell within the item
you need to find the right tablecell (column) then pull your listbox out of that
I'm not going to include code because I "cheat" - reference the tablecell by hardcoding the index

If that's the case then why does it work elsewhere? i.e. why does it work in the "View" command but not the "Edit?" And could you post some of your code so I can kinda see the general idea of what you do?

[Elliott]

can't answer that (sorry)
it's a dumb question but...
when the CommandName is "Edit" what is the type of the e.Item?

I would still try something like

if (e.CommandName == "Edit" && typeof e.Item is EditFormItem) // syntax may be wrong, I'm a VB programmer
{
     GridEditFormItem item = (GridEditFormItem)(e.Item as GridDataItem).EditFormItem;
     TableCell TC = item.TableCell[5];
     ListBox lb = (ListBox)TC.FindControl("lstMembers");
}

Tried that, still didn't work. item doesn't have a TableCell[] property, so I had to just use Cells. That might just be a VB/C# thing though. 
TC, which I set to be Cells[1] (corresponds to the location of the form in my Grid) appears to have no controls, as confirmed in a breakpoint.  e.Item is a GridDataItem, even when the CommandName is Edit, that's why I have to 1) extract the EditFormItem, and 2)cast it as a GridEditFormItem.

Hello Kyle,

Since the EditCommand is too early to access the edit form items, you can access the items in the ItemDataBound event of the grid as shown below.
C#:

protected void grid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
 if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
 {
   GridEditFormItem item = (GridEditFormItem)e.Item;
   RadListBox list = (RadListBox)item.FindControl("lstMembers");
 }
}

Thanks,
Shinu.
