[Solved] RadNumericBox properties in DataGridNumericalColumn

[Patrick]

Hi,

I use a numeric column in a datagrid (DataGridNumericalColumn) and it is said in the documentation
that it uses the control RadNumericBox in edit mode.

- How to define the properties of RadNumericBox (minimum, maximum, SmallChange ...) in the column definition ?
- Is it possible to restrict the input to integers.

Thanks a lot for your response.

Note: I found another problem with using the numeric column. If I set the PropertyName property with a nullable type in my ViewModel, I have the binding error below when I change the value of the column.

Error: Cannot save value from target back to source. BindingExpression: Path='Numero' DataItem='Resultat'; target element is 'Telerik.UI.Xaml.Controls.Input.RadNumericBox' (Name='null'); target property is 'Value' (type 'Object').

Hello Patrick,

The DataGridNumericalColumn handles the edit mode internally and it is not possible to configure the RadNumericBox that represents it. If you wish to have a customized RadNumericBox you can create a DataGridTemplateColumn.
As I was unable to reproduce this error, could you please send us a sample project that reproduces it?. Also, could you please clarify what version of our controls do you use - 8.0 or 8.1?

I am looking forward to your reply.
