Question

I would like to bind GrivdViewColumn’s Width Property with my ViewModel. Lets say an instance of ViewModel is the Datacontext of the Window. ViewModel has got Properties called IdWidth, LastNameWidth, FirstNameWidth. And that Window contains the following given ListVeiw in a stackPanel. Everything is fine but somehow the Width Property of GridViewColumn is not bound. Please post the code after making sure that it works.

<ListView Name="PatientListView"
          ItemsSource="{Binding Patients}"
          SelectionMode="Single">
  <ListView.View>
    <GridView>
      <GridView.Columns>
        <GridViewColumn Header="Patient-Id"
                        Width="{Binding IdWidth, Mode=TwoWay}"
                        DisplayMemberBinding="{Binding PatientId}"/>

        <GridViewColumn Header="Last Name"
                        Width="{Binding LastNameWidth, Mode=TwoWay}"
                        DisplayMemberBinding="{Binding LastName}"/>

        <GridViewColumn Header="Last Name"
                        Width="{Binding FirstNameWidth, Mode=TwoWay}"
                        DisplayMemberBinding="{Binding FirstName}" />
      </GridView.Columns>
    </GridView>
  </ListView.View>
</ListView>

Edit: FrameworkElement is not required for DataBinding, sorry for this incorrect interpretation of the citation from MSDN below.
See comments and @H.B. ‘s answer

GridViewColumn does not inherit from FrameworkElement, which is required for databinding.

see MSDN:

Support for data binding and dynamic resource references: […], but the ability to resolve a member value that is stored as an Expression (the programming construct that underlies both data binding and dynamic resources) is implemented by FrameworkElement
