How to create style for GridViewDataColumn and replace his Header property

Question

I want to localize my GridView from xml file which has translation for my GridView headers.

I use next code:

    <Window.Resources>
    <Style TargetType="{x:Type telerik:GridViewDataColumn}">
        <Setter Property="Header" >
            <Setter.Value> 
                <TextBlock Text="{Binding someValue}"/>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>


<Grid>
    <telerik:RadGridView HorizontalAlignment="Left" Name="radGridView1"  VerticalAlignment="Top"  >

    </telerik:RadGridView>

</Grid>

This code not Works and gives exception that TextBlock cannot be cast to the object. I am planning to bind TextBlock to the XmlNode value and get appropriate translation by Header system name
