Set DetailTableView Datasource to empty

[Angie]

I have a master grid to which I am binding a Detail grid only if it is part of a "series".  All other rows should not have a detail table.  There's no real key relationship between the master and detail table otherwise.

When I try to just bind the detail grid on only the rows which require it, it binds the entire master table view to the detail grid on the rows which don't.  I cannot get the detail grid to have a null datasource.

I don't know if I'm explaining it well, but how do I prevent the grid from showing the entire master table view on the detail view when there are no records to explicitly bind?

protected void RadGridCE_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)
        {
            GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;

            if (dataItem["is_series"].Text == "1")
            {
                int series_id = int.Parse(dataItem["series_id"].Text);
                e.DetailTableView.DataSource = (FarranMedia.Classes.OnlineCE.CECourseGetBySeriesID(series_id)).Tables[0];
            }
            else
            {

                e.DetailTableView.DataSource = null;

            }

        }

Thanks.

Angie, I think that assigning an empty data source of objects inside the else statement should be sufficient, namely:

protected void RadGridCE_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)
        {
            GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;

            if (dataItem["is_series"].Text == "1")
            {
                int series_id = int.Parse(dataItem["series_id"].Text);
                e.DetailTableView.DataSource = (FarranMedia.Classes.OnlineCE.CECourseGetBySeriesID(series_id)).Tables[0];
            }
            else
            {

                e.DetailTableView.DataSource = new Object[0];

            }

        }

Hope this is helpful.

This solution did the trick for me, thanks.
