Setting previous values with Custom Edit Forms using rad combo/text boxes

[Nick]

I have am using a custom edit form to update & insert information in my radgrid which contains 3 radcomboboxes & 1 radtextbox.  Update works great, edit works but it doesn't set the default values of the drop downs to the current values.  I am NOT using auto insert/update/delete.  I can set the text value by doing:

Text='<%# Eval( "Description" ) %>'

But if I try this with the comboboxes and the "SelectedValue=" I get a "Selection out of range Parameter:value" error.  I am binding my controls from db information in a hooked up RadGrid1_ItemDataBound method.  I'm thinking I have to set the SelectedValue somewhere in this method, after something like:

GridItem gridItem = e.Item as GridItem;
if (!gridItem.OwnerTableView.IsItemInserted)

then where do I go from here?  I've spent too long looking through examples and searching this forum, so I apologize if this is easy or should have been easy to find out how.
Thanks.

Hello Nick,

You can try out the following code to set the SelectedValue of a ComboBox control in the custom EditFormTemplate of your grid:
aspx:

  <EditFormSettings EditFormType="Template" >
               <FormTemplate>
                   <telerik:RadComboBox ID="RadComboBox" runat="server">
                   </telerik:RadComboBox>
               </FormTemplate>
  </EditFormSettings>

cs:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridEditFormItem && e.Item.IsInEditMode && !e.Item.OwnerTableView.IsItemInserted)
        {
            GridEditFormItem formItem = (GridEditFormItem)e.Item;
            RadComboBox dropdown = (RadComboBox)formItem.FindControl("RadComboBox");
            dropdown.DataSourceID = "SqlDataSource1";
            dropdown.DataTextField = "Category";
            dropdown.DataValueField = "Category";
            dropdown.SelectedValue = DataBinder.Eval(formItem.DataItem, "Category").ToString();
        }
   }

Thanks
Princy.
