Hello,
I am new at using Telerik products.
I am using a GridView with Hierarchic levels.
I am trying to add a combo box in it, so I created a GridViewComboBoxColumn object , and added it to the GridView like this :
myGridView.MasterGridViewTemplate.Columns.Add(myComboBoxColumn); and it works.
But now, I want to add the combo to the hierachical second level on the GridView, something like that :
myGridView.MasterGridViewTemplate.ChildGridViewTemplates.Insert(4,myComboBoxColumn);
but I get an error message telling that a GridViewComboBoxColumn object is not assignable to a GridViewTemplate.
So please can you tell me how I could add the GridViewComboBoxColumn to the GridView at this level ?
Thank you.

Thank you for your answer.
Now I can add the field to the grid, but when added, it doesn't react like a combo box, but just like an empty text box (???)
When I tried to add it to the higher level of the GridView (just for a test), it worked perfectly like a combo box.
Here is the code I use for adding the combo to the templates level of the GridView :
var myCombo= new GridViewAdvComboBoxColumn
{
FieldName = "MyValues",
HeaderText = "Valeurs",
MinWidth = 150,
MaxWidth = 150,
UniqueName = "MyValues",
Width = 150,
DataSource = SessionTabParent.AssociatedSession.InvoicingController.GetDataById(myId),
DisplayMember = "myLabel",
ValueMember = "myLabel"
};
myGridView.MasterGridViewTemplate.ChildGridViewTemplates[0].Columns.Add(myCombo);

Sorry, it seems that my GridView was in read-only mode, and that's why the Combo appeared like an empty textbox.
Now it works, but the dropdown part is not visible until I click on the combo field.
Is there a way to make it graphically obvious that it is a combo box, even when no clicking at it ?

Hello Bruno,
Thank you for your question.
As Emanuel said, the default behavior of GridViewComboBoxColumn is to show the DropDownList editor only in edit mode. You can create a Custom Cell to customize the cell elements and appearance according to your requirements.
I hope it helps.
Best wishes,
