[Solved] Getting GridException when searching for footer in Hierarchical Grid

[Greg Smith]

I followed the HowTo on setting footer values in the code behind, but I'm getting a GridException because the footer value I'm looking for doesn't exist in the Detail Table, but the ItemDataBound is fired for all tables.

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
   {
        if (e.Item is GridDataItem)
       {
           GridDataItem dataItem = (GridDataItem)e.Item;
           sum+=double.Parse((dataItem[ "Template1"].FindControl("TextBox1") as TextBox).Text);
       }
        else if (e.Item is GridFooterItem)
       {
           GridFooterItem footer = (GridFooterItem)e.Item;
           (footer[ "Template1"].FindControl("TextBox2") as TextBox).Text = sum.ToString();
           clientID = (footer["Template1"].FindControl("TextBox2") as TextBox).ClientID;
       }
   }

The bold line above throws the exception because the ItemDataBound was triggered by the Detail table which doesn't have a "Template1" column. How can I check for the existence of the "Template1" column thereby preventing the exception?


Thanks

Hello Greg,

You can differentiate between the tableview instances in a hierarchical grid using their Name property. Check out the following document which explains on how this can be done:
Distinguish grid rows in hierarchy on ItemCreated/ItemDataBound
