I have a DataGrid with a few columns. I do not set the ReadOnly property for the grid or for any columns and while in runtime I can see that the column with the CellEditor ReadOnly property value is False.
However I cannot see the ComboBox im supposed to with the CellEditor. I was worried that maybe some style from controls up in the logical tree might be affecting this so i set "empty" styles for all types just in case but this did not work.
Im including the xaml and I hope you can point out anything that might be wrong or weird. I also wanted to ask if you can point out generally what might be the things that might affect the display of a CellEditor or prevent the DataGrid from entering edit mode.
One more thing. In the grid when I go over a Cell and hit F2 I do see the Row Selector Pane switch to the editting glyph however the CellEditor does not appear.
Here is the xaml, the code behind contains nothing special:
