How can I prevent a user from resizing GridViewColumns withing a ListView control?

Answer 1

A smooth solution:

<GridViewColumn ...>
    <GridViewColumn.HeaderContainerStyle>
        <Style TargetType="{x:Type FrameworkElement}">
            <Setter Property="IsHitTestVisible" Value="False"/>
        </Style>
    </GridViewColumn.HeaderContainerStyle>
</GridViewColumn>

Answer 2

i found a solution and probably it will help someone else someday ;)

you have to override the GridViewColumnHeader's ControlTemplate (default template is here ) and remove the PART_HeaderGripper from the template in order to prevent resizing of your columns.

there is another solution that comes up with subclassing GridViewColumn described here. for representation purposes i prefer xaml only solutions though

Answer 3

I was able to do something similar with the instructions in this post

I wasn't able to use a full XAML solution, since I was building everything in my code behind due to the dynamics of it. Worked great on the first try.

Answer 4

For those looking for a quicker and simpler answer.

Set IsEnabled to False in the ColumnHeaderContainerStyle. This will prevent the user from resizing.

Like this:

<GridView.ColumnHeaderContainerStyle>
  <Style TargetType="{x:Type GridViewColumnHeader}">
       <Setter Property="IsEnabled" Value="False"/>
  </Style>
</GridView.ColumnHeaderContainerStyle>

If you want to fix the disabled grayed out color add a trigger on the IsEnabled property and fix what you need.

<GridView.ColumnHeaderContainerStyle>
   <Style TargetType="{x:Type GridViewColumnHeader}">
       <Setter Property="IsEnabled" Value="False"/>
    <Style.Triggers>
       <Trigger Property="IsEnabled" Value="False">                
          <Setter Property="TextElement.Foreground" Value="Black"/>                       
       </Trigger>
    </Style.Triggers>
  </Style>
</GridView.ColumnHeaderContainerStyle>

This answer might not be as elegant as other posted; but in my case all I needed was a quick way of doing it.

Hope this helps someone.

Darkonekt's answer is good, however it may be preferable to set IsHitTestVisible to false instead of IsEnabled. This has the benefit of not greying out the headers.

<GridView.ColumnHeaderContainerStyle>
    <Style BasedOn="{StaticResource {x:Type GridViewColumnHeader}}" TargetType="{x:Type GridViewColumnHeader}">
        <Setter Property="IsHitTestVisible" Value="False"/>
    </Style>
</GridView.ColumnHeaderContainerStyle>
