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

Can anybody help me? Is this a known bug? Or isn't this reproducable? Should I add some pictures to illustrate the problem?

 greets,

Matt

To give the other users the solution too:

if a validation error occurs the font (foreground) is set to white and the background to read.

in the combobox only the selected item is background red and all others white. so the only way to display this properly is to change the foreground color.
