I want to show multipcolumn into combobox of GridViewComboBoxColumn at CellEditTemplate mode. Item of combobox in the GridViewComboBoxColumn has header for column. Ex:

When i chose LocationID, then the comboBox in GridViewComboColumn show:
|           AD              |
|       LocationID    |       LocationName      |
|         AD                |         Andorra                |
|         AE                |  United Arab Emirates   |
|         AT                |         Austria                  |

Hello dao hong ninh,

You may try to work with the ItemTemplate of the GridViewComboBoxColumn as demonstrated in details in our online documentation.

Hi dao hong ninh,

I would need a bit more clarification on your issue. Do you want to put a grid inside the GridViewComboBoxColumn ? What do you mean by choosing LocationID - as far as I can see it is a column of the grid you want to show inside the ComboBox ? What do you want to select from the ComboBox and consequently - what do you want to be displayed in the GridViewComboBoxColumn afterwards ? Furthermore, you may take a look at this blog post for a reference on how to play along a bit with the Template of the RadComboBoxItem.
 

Best wishes,
