RadMaskTextInput stretch

[Luigi]

Hi,

I tried to use a RadMasketTextInput instead of a standard TextBox, mainly because of the SelectionOnFocus/Selectall property.
Always wotks well, but the width of control doesn't use all the space left in the parent as a TextBox, in the same position, does.
I tried with stackpanel, dockpanel and Grid, this is the attempt with dockpanel:

<DockPanel Grid.Row="0" Grid.Column="0" Margin="12,0,0,0" HorizontalAlignment="Stretch">
				<Label VerticalAlignment="Center" 
Content="{DynamicResource  ResourceKey={x:Static r:ResourcesKeys.NameLabel}}" />
	<t:RadMaskedTextInput 
	  HorizontalAlignment="Stretch"
	 SelectionOnFocus="SelectAll"
         Value="{Binding SorgenteName}"/>			
</DockPanel>

And with textbox:

<DockPanel Grid.Row="0" Grid.Column="0" Margin="12,0,0,0" HorizontalAlignment="Stretch">
				<Label VerticalAlignment="Center" 
				    Content="{DynamicResource  ResourceKey={x:Static r:ResourcesKeys.NameLabel}}" />
				<TextBox 
									  HorizontalAlignment="Stretch"
							Text="{Binding SorgenteName}"/>
			</DockPanel>

With textbox I have the desired layout.

Thank you in advance

Hello Gianluca Zanellato,

I have tried to reproduce the mentioned behavior on my side but to no success. Both controls, from the provided code snippets, visualize correctly on my end. That said, I have attached a sample project, so could you edit it to match the observed behavior on your side?

The difference is the use of dockpanel. 
Now it is correct.
Thank you
