Hi Daniel,

I just created a small sample to try your mask out and it works for me. I get the expected output. Here's what I'm using to test it out:

            <ige:XamMaskedEditor x:Name="maskedEditor"  Mask="{}{number:0-255}.{number:0-255}.{number:0-255}.{number:0-255}" />

            <TextBox Grid.Row="1" Text="{Binding ElementName=maskedEditor, Path=Value}" />

Basically the text box displays the correct expected value that's entered int the masked editor. Can you provide any more info on any other settings on the masked editor or how you are making use of it? It would be best if you could attach a small sample that demonstrates the issue so we can check it out.

As a side note, try setting the AllowShiftingAcrossSections property to false. You don't have to do it if you are using number sections as you are, but for other textual masks with multiple sections, to prevent text shifting across sections, you would have to set this.

Thanks, 

Sandip
