Hi there,

when I insert decimal values in datagrid I get diferent results if pressed ',' or '.'

Eg. value 7,25

When I insert 7,25 with ',' the final result is 725

but

When I insert 7,25 with '.' the final result is 7,25

I want that was indiferent press ',' or '.' the final result was always the same!

I check every char insert on the grid but  I CanĀ“t assign olther value to a routed event that is already in use !

 void RadGridView1_KeyDown(object sender, KeyEventArgs e) 
        { 
            if (e.Key == Key.Decimal) 
            { 
                e.Handled = true
                e.Source = "2"; // ==> error 
            } 
            if (e.Key == Key.OemComma) 
            { 
                e.Handled = true
            } 
            if (e.Key == Key.OemPeriod) 
            { 
                e.Handled = true
            } 
        } 




it's possible when the user press ',' change the value to '.' ?

Any ideias?

Thanks,
Jose Oliveira

Hello Jose Oliveira,

Instead of listening to every KeyStroke , you might try the following approach :
For your column  DataMemberBinding Binding you may set a custom IValueConverter to take care of parsing the string to the correct decimal.

In the ConvertBack method of the IValueConverter you may write your own logic to correctly parse the input string to a decimal.

Let me know in case you need  assistance with implementing this approach .

All the best,
