Different behavior when binding mask

Felicia posted over 14 years ago

Using the XamNumericEditor when i set explicitly the Mask in xaml as "{}{double:5.2}" the caret is placed as i want before the decimal separator.

If i set a property Mask in a view model and bind the value to Mask in xaml the caret is placed at the end of the text and i can't type numbers.

Here is the code of the second case:

<Editors:XamNumericEditor x:Name="Value"

Mask="{Binding Mask}"

PromptChar=" "

DataMode="IncludeBoth"

DisplayMode="IncludeLiterals"

IsAlwaysInEditMode="True"

Text="{Binding Value, UpdateSourceTrigger=PropertyChanged}" />

public string Mask

{

get

{

return "{double:5.2}";

}

Why is this happening? How could i get the first behaviour using data binding of the mask?
