Hi Richard,

Try the following code snippet.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
  if (e.Item is GridFilteringItem)
   {
      GridFilteringItem filterItem = (GridFilteringItem)e.Item;
      RadComboBox combo = (RadComboBox)filterItem["colUniquename"].FindControl("RadComboBox1");//accessing combobox
      DataTable dt1 = (DataTable)Session["dt"];
      combo.DataSource = dt1; // setting datasource
      combo.DataTextField = "CustomerID";
      combo.DataValueField = "CustomerID";
      combo.DataBind();
   }
}

Thanks,
Shinu.
