This is my first experience using the UltraWebGrid.  I'm trying to delete a row from a grid using the row's delete button.  The grid is bound to a List collection.  Had trouble from the start.  I tried to delete server side in the button click event (using Rows.removeAt(index) ) but kept getting this error:

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

I could debug and see the collection had the right number of items.  Determined that this was related to doing a databind in the OnInit() event.  That was needed to get around this error:

Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

which I got because I need to do this:

<CellTemplate>                           
    <asp:Label ID="lblName" runat="server" Text='<%# Eval("Type.Name") %>' />
</CellTemplate>

I was able to get the delete to work in the CellButtonClick (I have multiple buttons) server side by deleting from the DB and refreshing:

int reqID = Convert.ToInt32(e.Cell.Row.Cells.FromKey("ID").Value);

if (e.Cell.Column == uwgRequests.Columns.FromKey("Delete"))
{
    ServReqManager.DeleteRequest(reqID);
    ServReqManager.CommitChanges();
    RefreshGrid();
}

Things were OK.  My problem now is I need to confirm the delete using javascript.  Ideally I could just toss up a confirm box and then continue on to the CellButtonClick event as before.  Is there a way to do that I haven't seen in any examples.

Alternatively I considered trying to delete client side as suggest by many posts in the forums.  However I get the same 'Index was out of range' error as above.

    function confirm_delete(gridName, cellId) {
       
        var cell = igtbl_getCellById(cellId);
       
        if (cell.Column.Key == "Delete") {
            if (confirm("Are you sure you want to delete this Service Request?")) {

                var grid = igtbl_getGridById(gridName);
                grid.AllowDelete = 1;
                var row = cell.getRow();
                row.deleteRow();

                return true;
            }
            else
                return false;

Any tips or suggestions?
