Binding Mask property

[User (Old forums)]

Hi everyone,

I’m trying to use MaskedTextBox outside from a Datagrid and to bind its Mask property:

<xcdg:MaskedTextBox x:Name=”msk” Value=”10″ ValueDataType=”{x:Type sys:Single}” Height=”20″ Mask=”{Binding Converter={StaticResource MyConvDeTest}}”/>

My converter is like this:

public class MyConvDeTest : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
Person supplier = value as Person;
if (supplier == null) return null;

string symbol = string.Empty;
if (supplier.Symbol != null)
symbol = ” ” + supplier.Symbol;
return “#.# ” + symbol;
}

So this idea is to provide a dynamic mask to my MaskedTextBox depending of the object binded.

But it always launch an exception: The mask cannot be applied to the current text. (in MaskCoerceValueCallback.

So how can I bind the mask to my object?

The issue itself isn’t with your binding or your converter.

If you try setting #.# as the mask directly, you would get the exact same exception.

The representation of the value (10.0) cannot be applied to your mask as there’s only one space for one character before your decimal separator.

The Xceed’s MaskedTextBox, just like Microsoft’s MaskedTextBox does not allow for variable length masking.

So this means that I can’t modify Mask dynamicly?
