Hello to all,

i have a UltraGrid and a problem with the column sorting.

If i use the C# nullabe type or String.Empty  for DateTime (DateTime?) the sorting dosn't realy work fine.

Has anybody  experience with nullable types or empty DateTime Value and UltraGrid or how to display and sorting null values with the grid.

The reason why i use the nullable or empty  types is that we have date values in the database like this "01.01.0001". For all this values the grid should dislpay an empty column field.

Thanks and regards

Daniel
