How can I hide a control so that it no longer takes up space in WPF?

Question

I have a DataTemplate that I am using for a cell in a gridview. I would like to switch between the progress bar and the text/link block. Is there a way to hide an element so that it is removed from the flow and takes up no space while it is hidden (like "display:none" in CSS)? Is there a better way to approach this?

DataTemplate looks like:

<DataTemplate x:Key="DataTemplate2">
    <StackPanel Height="40">
        <TextBlock Visibility="{Binding ButtonVisibility}">
            <Hyperlink Click="btn_Authorise">
                <InlineUIContainer>
                    <TextBlock Text="{Binding Button}" />
                </InlineUIContainer>
            </Hyperlink>
        </TextBlock>
        <ProgressBar Value="{Binding Progress}"
                     Visibility="{Binding ProgressVisibility}"
                     Height="15"
                     Width="150"
                     Background="{DynamicResource NormalBrush}"
                     BorderThickness="0"
                     BorderBrush="#FF8D8D8D"
                     Style="{DynamicResource ProgressBarStyle1}" />
    </StackPanel>
</DataTemplate>

Answer 1

Visibility.Collapsed is probably what you need (as opposed to Visibility.Hidden which still makes the control take part in layout calculations)

Also see the Visibility enumeration reference.

Answer 2

Yep.

Visibility is an enumeration, Visible, Hidden, and Collapsed. Hidden is just non-visible, whereas Collapsed means it takes no space also
