I did try to ge this to bind to the ContextMenu using 'ElementName', but in the end, got it work using Properties in the VM, e.g.

<pre><code>bool _isHidden;
public bool IsHidden
{
 get { return _isHidden; }
 set
 {
 if (value != _isHidden)
 {
 _isHidden = value;
 RaisePropertyChanged("IsHidden");
 RaisePropertyChanged("IsVisible");
 }
 }
}

public Visibility IsVisible
{
 get { return IsHidden ? Visibility.Hidden : Visibility.Visible; }
}
</code></pre>

and in the XAML:

<pre><code>&lt;Window.ContextMenu&gt;
 &lt;ContextMenu&gt;
 &lt;MenuItem Header="Hidden" IsCheckable="True" IsChecked="{Binding IsHidden}" /&gt;
 &lt;/ContextMenu&gt;
&lt;/Window.ContextMenu&gt;

Ok, this has been quite the exercise for a WPF n00b.

IanR thanks for the suggestion I used a similar aproach but it dosent take you all the way.

Here is what I have come up with if anyone can find a more consistent way of doing it I will appreciate any comments:

Impediments:

<ol>
<li>DataGridColumnHeader does not support a context menu. Therefore the context menu needs to be applied as a Style.</li>
<li>The contextmenu has its own datacontext so we have to use findancestor to link it to the ViewModels datacontext.</li>
<li>ATM the DataGrid control does not parse its datacontext to its Columns. This could be solved in codebehind however we are using the MVVM pattern so I decided to follow <a href="http://blogs.msdn.com/jaimer/archive/2008/11/22/forwarding-the-datagrid-s-datacontext-to-its-columns.aspx" rel="nofollow noreferrer">jamiers</a> approach</li>
</ol>

Solution:

Place the following two blocks of code in Window.Resources

<pre><code> &lt;Style x:Key="ColumnHeaderStyle"
 TargetType="{x:Type toolkit:DataGridColumnHeader}"&gt;
 &lt;Setter Property="ContextMenu" 
 Value="{StaticResource ColumnHeaderContextMenu}" /&gt;
 &lt;/Style&gt; 

 &lt;ContextMenu x:Key="ColumnHeaderContextMenu"&gt;
 &lt;MenuItem x:Name="MyMenuItem"
 IsCheckable="True"
 IsChecked="{Binding DataContext.IsHidden, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type toolkit:DataGrid}}}"/&gt;
 &lt;/ContextMenu&gt;
</code></pre>

The datagrid then looks something like this in XAML

<pre><code> &lt;toolkit:DataGrid x:Name="MyGrid"
 AutoGenerateColumns="False"
 ItemsSource="{Binding SampleCollection, Mode=Default}"
 EnableColumnVirtualization="True"
 IsReadOnly="True"
 ColumnHeaderStyle="{StaticResource ColumnHeaderStyle}"&gt;
 &lt;toolkit:DataGrid.Columns&gt;
 &lt;toolkit:DataGridTextColumn Binding="{Binding Path=SamplingUser}"
 Header="{Binding (FrameworkElement.DataContext).IsHidden, RelativeSource={x:Static RelativeSource.Self}}"
 Visibility="{Binding (FrameworkElement.DataContext).IsHidden,
 RelativeSource={x:Static RelativeSource.Self},
 Converter={StaticResource booleanToVisibilityConverter}}"/&gt;
</code></pre>

So the visibility property on the DataGridColumn and the ischeked property are both databound to the IsHidden property on the viewModel.

In the ViewModel:

<pre><code> public bool IsHidden
 {
 get { return isHidden; }
 set 
 { if (value != isHidden)
 {
 isHidden = value;
 OnPropertyChanged("IsHidden");
 OnPropertyChanged("IsVisible");
 }
 }
 } 
</code></pre>

The Helper class defined by Jaimer:

<pre><code>class DataGridSupport
{
 static DataGridSupport() 
 {

 DependencyProperty dp = FrameworkElement.DataContextProperty.AddOwner(typeof(DataGridColumn)); 
 FrameworkElement.DataContextProperty.OverrideMetadata ( typeof(DataGrid), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.Inherits, new PropertyChangedCallback(OnDataContextChanged)));

 }

 public static void OnDataContextChanged ( DependencyObject d, DependencyPropertyChangedEventArgs e)
 { 
 DataGrid grid = d as DataGrid ; 
 if ( grid != null ) 
 { 
 foreach ( DataGridColumn col in grid.Columns ) 
 { 
 col.SetValue ( FrameworkElement.DataContextProperty, e.NewValue ); 
 } 
 } 
 }
}
</code></pre>

Instanciated in the viewmodel (just to show done through Unity in real project) 

<pre><code> private static DataGridSupport dc = new DataGridSupport();
</code></pre>

Cheers,

Instead of booleanToVisibilityConverter you can use x:static

I've been looking for a generic, XAML (i.e., no code-behind), automatic and simple example of a column chooser context menu that binds to a WPF DataGrid column header. I've read literally hundreds of articles, but none of them seem to do exactly the right thing, or they're no generic enough. So here's what I think is the best combined solution:

First, put these in the resource dictionary. I'll leave it as an exercise to the reader to write the Visibility/Boolean converter to ensure the checkboxes check when the column is visible and vice-versa. Note that by defining x:Shared="False" for the context menu resource, it'll get instance-specific state which means that you can use this single template/resource for all your datagrids and they'll all maintain their own state.

<pre><code>&lt;Converters:VisiblityToInverseBooleanConverter x:Key="VisiblityToInverseBooleanConverter"/&gt;

&lt;ContextMenu x:Key="ColumnChooserMenu" x:Shared="False"
 DataContext="{Binding Path=PlacementTarget, RelativeSource={RelativeSource Self}}" 
 ItemsSource="{Binding Columns, RelativeSource={RelativeSource AncestorType={x:Type sdk:DataGrid}}}"&gt;
 &lt;ContextMenu.ItemContainerStyle&gt;
 &lt;Style TargetType="MenuItem"&gt;
 &lt;Setter Property="Header" Value="{Binding Header}"/&gt;
 &lt;Setter Property="AutomationProperties.Name" Value="{Binding Header}"/&gt;
 &lt;Setter Property="IsCheckable" Value="True" /&gt;
 &lt;Setter Property="IsChecked" Value="{Binding Visibility, Mode=TwoWay, Converter={StaticResource VisiblityToInverseBooleanConverter}}" /&gt;
 &lt;/Style&gt;
 &lt;/ContextMenu.ItemContainerStyle&gt;
&lt;/ContextMenu&gt;

&lt;Style x:Key="ColumnHeaderStyle" TargetType="{x:Type Primitives:DataGridColumnHeader}"&gt;
 &lt;Setter Property="ContextMenu" Value="{StaticResource ColumnChooserMenu}" /&gt;
&lt;/Style&gt;

&lt;ContextMenu x:Key="GridItemsContextMenu" &gt;
 &lt;MenuItem Header="Launch Do Some other action"/&gt;
&lt;/ContextMenu&gt;
</code></pre>

Then define the DataGrid as follows (where OrdersQuery is some data source exposed by the View-model):

<pre><code>&lt;sdk:DataGrid ItemsSource="{Binding OrdersQuery}"
 AutoGenerateColumns="True" 
 ColumnHeaderStyle="{StaticResource ColumnHeaderStyle}"
 ContextMenu="{StaticResource GridItemsContextMenu}"&gt;

 &lt;!-- rest of datagrid stuff goes here --&gt;

&lt;/sdk:DataGrid&gt;
</code></pre>

This will give you the following:

<ol>
<li>A context menu bound to the column headings which acts as a column chooser.</li>
<li>A context menu bound to the items in the grid (to perform actions on the items themselves - again, the binding of the actions is an exercise for the reader).</li>
</ol>

Hope this helps people who've been looking for an example like this.

I want to control <code>DataGrid</code> column visibility through a <code>ContextMenu</code> available to the user by right-clicking the column header. The <code>ContextMenu</code> displays the names of all available columns. I am using MVVM design pattern.

My question is: How do I bind the <code>DataGridColumn</code>'s <code>Visibility</code> property to the <code>IsChecked</code> property of a <code>MenuItem</code> located in the <code>ContextMenu</code>.

Some mockup code:

<pre><code>&lt;UserControl.Resources&gt; 
 &lt;ContextMenu x:Key="ColumnHeaderContextMenu"&gt; 
 &lt;MenuItem Header="Menu Item..1" IsCheckable="True" /&gt; 
 &lt;/ContextMenu&gt; 
 &lt;Style x:Key="ColumnHeaderStyle" 
 TargetType="{x:Type toolkit:DataGridColumnHeader}"&gt; 
 &lt;Setter Property="ContextMenu" 
 Value="{StaticResource ColumnHeaderContextMenu}" /&gt; 
 &lt;/Style&gt; 
 &lt;BooleanToVisibilityConverter x:Key="booleanToVisibilityConverter" /&gt; 
&lt;/UserControl.Resources&gt; 
</code></pre>

...flaf flaf flaf

<pre><code>&lt;toolkit:DataGrid x:Name="MyGrid" AutoGenerateColumns="False" 
 ItemsSource="{Binding MyCollection, Mode=Default}" 
 EnableColumnVirtualization="True" IsReadOnly="True" 
 ColumnHeaderStyle="{StaticResource ColumnHeaderStyle}"&gt; 
 &lt;toolkit:DataGrid.Columns&gt; 
 &lt;toolkit:DataGridTextColumn Binding="{Binding Path=MyEntry}" 
 Header="MyEntry" Visibility="{Binding IsChecked, Converter=
 {StaticResource booleanToVisibilityConverter}.... /&gt;
 &lt;/toolkit:DataGrid.Columns&gt; 
&lt;/toolkit:DataGrid&gt; 
</code></pre>

If I am being unclear please let me know and I will attempt to elaborate.

Cheers,
