GridViewColumn Header attribute databinding problem

[Brian]

The Header attribute of my GridViewDataColumn is not binding.

<telerik:GridViewDataColumn Width="1.5*" UniqueName="DynamicColumn1" Header="{Binding DynamicColumn1Header}" DataMemberBinding="{Binding PositionName}" IsReadOnly="True"/>

I have also tried the following with no luck:

<telerik:GridViewDataColumn Width="1.5*" UniqueName="DynamicColumn1" DataMemberBinding="{Binding PositionName}" IsReadOnly="True">
    <telerik:GridViewDataColumn.Header>
        <TextBlock Text="{Binding DynamicColumn1Header}"/>
    </telerik:GridViewDataColumn.Header>
</telerik:GridViewDataColumn>

Please advise.  Thanks.

Hi,

 With this binding you expect to have DynamicColumn1Header in the grid DataContext. Can you verify if this is the case? Where exactly this property is declared?

We are using typical MVVM.  The datacontext for the View (which contains the GridView) is set to the ViewModel which contains the property "DynamicColumn1Header".

private string _dynamicColumn1Header;
 /// <summary>
/// DynamicColumn1 header display value (changes based on PositionType)
/// </summary>
public string DynamicColumn1Header
{
    get { return this._dynamicColumn1Header; }
    set
    {
        if (value != this._dynamicColumn1Header)
        {
            this._dynamicColumn1Header = value;
            this.RaisePropertyChanged("DynamicColumn1Header");
        }
    }
}

The setter is indeed being called and change notification occurs.  However, this value is not reflected in the Header.
