Hello,

I suppose that in your scenario the RadComboBox is placed in a TemplateColumn of a grid which is placed in the NestedViewTemplate of another grid which is inturn placed in the EditFormTemplate of the main grid. If thats the case, you can try out the following code to access the RadComboBox:
aspx:

 <EditFormSettings EditFormType="Template">
      <FormTemplate>
          <telerik:RadGrid ID="EditRadGrid" DataSourceID="SqlDataSource1" runat="server" AutoGenerateColumns="true" >
            <MasterTableView>
            <NestedViewTemplate>
              <telerik:RadGrid ID="NestedRadGrid" DataSourceID="SqlDataSource1" runat="server" AutoGenerateColumns="true" >
                <MasterTableView>
                 <Columns>
                  <telerik:GridTemplateColumn UniqueName="Column">
                   <ItemTemplate>
                    <telerik:RadComboBox ID="RadComboBox1" runat="server">
                    </telerik:RadComboBox>
                   </ItemTemplate>
                 </telerik:GridTemplateColumn>
               </Columns>
              </MasterTableView>
            </telerik:RadGrid>
          </NestedViewTemplate>
          </MasterTableView>
        </telerik:RadGrid>
     </FormTemplate>
 </EditFormSettings>

cs:

 protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
       foreach (GridEditFormItem editItem in RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem))
        {
            if (editItem.IsInEditMode)
             {
                RadGrid grid = (RadGrid)editItem.FindControl("EditRadGrid");
                foreach (GridNestedViewItem item in grid.MasterTableView.GetItems(GridItemType.NestedView))
                {
                    RadGrid nestedgrid = (RadGrid)item.FindControl("NestedRadGrid");
                    foreach (GridDataItem nestedDataItem in nestedgrid.MasterTableView.Items)
                    {
                        RadComboBox combobox = (RadComboBox)nestedDataItem["Column"].FindControl("RadComboBox1");
                        combobox.DataSourceID = "SqlDataSource1";
                        combobox.DataTextField = "Category";
                        combobox.DataValueField = "Category";
                    }
                }
            }
        }
    }

Thanks
