MaskedTextBox.Mask: Optional characters not allowed

[JuliaVasileva]

Hi,
I've been trying to create Mask for MaskedTextBox and faced a problem with optional characters.

The control seems to treat optional digits as mandatory.

Specifically:

Mask="N #90°" - where the 2 digits before the degree symbol are optional

However, values such as N 8° or N 12° are not valid

To make it valid, I need to input values with additional spaces like 'N 3°'

Hot to allow users to input values of different lengths without requiring additional spaces?

Hi,

How about using a prompt char of Empty:
<xctk:MaskedTextBox Mask="N #90°" PromptChar="" HorizontalAlignment="Center" VerticalAlignment="Center"/>
