StringFormat not working for GridViewDataColumn header

[Kristoffer]

<telerik:GridViewDataColumn DataFormatString="N0" DataMemberBinding="{Binding MyValue}" Header="{Binding MyLabel, StringFormat=This {0}}" />

"This " is not shown in my header. What am I doing wrong?

Hello,

Unfortunately, you cannot format the Header that way.

You can do it defining it like so:

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}">
    <telerik:GridViewDataColumn.Header>
        <TextBlock Text="{Binding HeaderName, StringFormat='This {0}', Source={StaticResource MyViewModel}}"/>
    </telerik:GridViewDataColumn.Header>
</telerik:GridViewDataColumn>

I hope this helps.

Kind regards,
