Please move this thread to the WPF forum (http://social.msdn.microsoft.com/Forums/en-US/wpf/threads), as this is a Windows Presentation (not Communication) Foundation issue.

Hi Sursh,

A ContentControl has a limited default style. The default ControlTemplate of the ContentControl contains nothing but the ContentPresenter, i.e. nothing but the content contained in the ContentControl will rendered. So setting the Height or Width property on the ContentControl makes no difference from the view of visual.

The solution is to create a new ControlTemplate for the ContentControl to add an UIElement in the ControlTemplate, binding the Width and Height property of the UIElement to the Width and Height property of the ContentControl. The following is a sample:

<Style TargetType="{x:Type ContentControl}">         
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ContentControl}">
                        <Grid>                       
                            <Border Width="{TemplateBinding Width}" Height="{TemplateBinding Width}" Background="{TemplateBinding Background}"/>
                            <ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center"/>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
</Style>

Put this XAML segment in the Resources section of the Window or application, so this style will be applied to all ContentControl in the Window or application.

Hope this helps.

Sincerely,
Linda Liu
