Binding GridDropDownColumn with List<>

[Peichung]

I know there are articles about how to bind GridDropDownColumn with SqlDataSource.  However, in my application, I have a data access layer returning a List<> for the GridDropDownColumn.  I am wondering how I can use List<> as the source for the GridDropDownColumn in the Edit mode.  With the following codes that I have, I have nothing shows up in either browse or edit mode.  Thanks,

<telerik:GridDropDownColumn
    DataField="CategoryId"
    HeaderText="Category"
    UniqueName="CategoryId"
    ListTextField="CategoryName"
    ListValueField="CategoryId"  />

    protected void uxApplicationGrid_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {

            GridEditableItem editedItem = e.Item as GridEditableItem;
            GridEditManager editMan = editedItem.EditManager;
            GridDropDownColumnEditor editor = editMan.GetColumnEditor("CategoryId") as GridDropDownColumnEditor;
            string selectedValue = editor.SelectedValue;
            editor.DataSource = CategoryDAL.GetCategorys();  // get List<> back from DAL
            editor.DataBind();
        }
    }

Hi Peichung,

Attached to this message, is a small application, which handles a functionality close to the one that you mentioned. I hope it helps.
