I have a datagrid with a colum of DropDownButton type, I did this a lot of times successfully, but now I don't know what's happens. It runs ok, but it don't show displaymember in the grid (it shows value member a id number). It only shows displaymember field if I click in the droDownButton.
Here a screenshoot to see it:
Do you know what could be the problem?
Thanks in advance
