New Post: Tab Stop not working on multiple controls

Hi,

I have recently instaled WPF Extended Toolkit and and tried to create simple WPF form, using VS 2012 an C#. It has few numeric up down boxes and button. The problem is that IsTabStop property doesn't work at all. True or False - when I press Tab - it moves the focus on every box.

I created new WPF form, without any code, then just dropped few numeric up down boxes - double, integer and decimal, one date time picker and again - IsTabStop property again does not work. On the same window I put ordinary TextBoxes, and IsTabStop works perfectly.

What am I doing wrong?

I just started to learn WPF and would appreciate any help!

Thank you!

Here is the XAML code of the blank window, that don't work:

<Window

        </Grid.ColumnDefinitions>

        <TextBox Grid.Column="1" HorizontalAlignment="Left" Height="30" Margin="110,170,0,0" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="105"/>
        <TextBox Grid.Column="1" HorizontalAlignment="Left" Height="30" Margin="110,220,0,0" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="105" IsTabStop="False"/>

    </Grid>
