Validation of controls

[Hassan Hussein]

I have a GridControl. In the Grid columns there are several different controls NumericUpDown, MonthCalendar etc.

Now, I expected that a NumericUpDown will not accept a non numeric value but it allows everything. I can also type "hello world!" into a MonthCalendar!!! It doesn''t make sense. Is there a way to make these controls self validate without code from my part (handling validation events)?

Many thanks

Hi Hassan,

For validating a numeric value cell the style.ValidateValue.NumberRequired property can be set to true and you can also set your own error message in the style.ValidateValue.ErrorMessage property. In order to validate a DateTime value cell the style.CellValueType can be set to typeof(System.DateTime). But this also throws the FormatException in the Output Debug window. Let us know if you have any further questions.
