Hi Michael.

I have a grid with a combo boxin it. When the grid first displays, the contents of each combo displays properly - but when I click in any grid cell, all the text in the conbo boxes get truncated - despite the fact that there's plenty of width in the combo.

This is a known issue. The grid column is bound to an integer foreign key, right? All you need to do is to see the inputMask on the column wide enough to accommodate the entire width of the DisplayValue in the combo box.
