I have a RadGridView with AutoGenerateColumns="true". Now i need to change one of the columns from being a plain column to a comboboxcolumn in code behind. What is the best way to do this?
So instead of displaying a grid with say 3 columns:
[id] [PersonId] [PersonName]
i want 2 columns and catch the column with PersonName an replace it with a comboboxcolumn so i can pick any row in the column. The comboboxvolumn sould display the [PersonName] but the value should be the [PersonId].
Also the grid is used to display various tables so i cant use a predefined template i think?
I dont know if this makes sense? :)

Hi,

In order to replace the default auto-generated column with GridViewComboBoxColumn, you should subscribe for the AutoGeneratingColumn event. Once it is raised for the column, you can replace e.Column with a new one. In case you prefer to not create a new column, you can also directly define a CellTemplate for the already generated column (e.Column).
You can learn more about how to configure GridViewComboBoxColumn properly in our online documentation here: ComboBox Column.

That is how far i got this morning. By using the AutoGeneratingColumn event. It seems to be the way to go. Is it possible to define just a celltemplate inside the GridView and how do i do this or what is the best way to do this? Also how do i assign the template. I guess it should be bound to two different colums? On for value & one for displaytext? Or do i need to define a whole column but only use the celltemplate from it? Im new to this so there might be a fiew dumb questions here! ;)

Hi Niklas,
You can place everything you wish in the DataTemplate you will use as a CellTemplate. For example, you can place two different controls and bind their content accordingly.
You can check the following article in our online documentation suggesting how to do so:
Setting CellTemplate and CellEditTemplate.
In the article the CellTemplate is assigned in XAML, however, you can also assign it to the e.Column as the AutoGeneratingColumn event is raised.
