Hi,

I've a problem with a ComboBox in the InsertionRow: if a ValidationError (in my case the Cell validates to an error if nothing is specified -> NotNullCellValidationRule) appears in the Cell where the ComboBox is, in the drop down list nothing but white lines are displayed. BUT if I move the cursor over one of the white lines the proper value is displayed.

 Additional information: in all other rows the ComboBoxes are working fine and display the correct values. I tried throwing a ValidationError on a specific selection instead of null (which is not possible here). It worked but the Cell didn't become red.

Is there anything special if I use ComboBoxes in an InsertionRow?

Is this a bug or a feature? :-D

Another question by the way: how does the CellValidationStyle Property work? Are there some examples?

greets,

Matt
