I too am experiencing the same issue.  The ItemCommand event does not get fired for my button in my grid.  Oddly, if I click on a column to sort it first, then click the button, the event fires.  Below is the code I have:

      <igtbl:UltraWebGrid ID="UltraWebGrid1" runat="server" Browser="Xml"
        Height="200px" Width="325px">
        <bands>

            <Columns>

                </Header>
              </igtbl:UltraGridColumn>
              <igtbl:TemplatedColumn Key="Update">
                <CellTemplate>
                  <asp:Button ID="Button1" CommandName="Foo" runat="server" Text="Button" />

Any help would be greatly appreciated.

Hello,

There are a few lines of code in the sample you provided that might be problematic.

1) The InitializeDataSource event needs to be used just to hook the event. DataBind() should not be called - it will be called internally by the grid itself.

2) You probably do not need the DataBinding event in this case -- just move the code to InitializeDataSource -- this should be fine.

3) How is the Browser="Xml" affecting this? If you remove this property, do you get better results?

Thanks for the response.  It was the DataBind call in the initializeDataSource event handler that was causing the issue.  Removing it has fixed the problem. Thank you for the quick response.
