Is there any way to bind the header of a column to a property of the ViewModel?

I tried 
<syncfusion:GridTextColumn MappingName="ColumnName"
                                               HeaderText="{Binding ColumnNameLabel}" />

but that fails.

Is there a way to do that?

Can you please provide an example of binding the header text without using a static resource?

In my situation I need to bind the heading text to a property on the data templates data context, the view model cannot be instantiated within XAML and the heading text value needs to change as the view model property is updated.
 
I have tried using various binding paths including element name etc but I can't seem to get it going. Any help would be appreciated.

Hi Jason,

You can achieve your requirement by using ElementName Binding as shown in the following code snippet.

<syncfusion:SfDataGrid.Columns>

                <syncfusion:GridTextColumn MappingName="EmployeeId" HeaderText="{Binding ElementName=datagrid, Path=DataContext.CustomHeaderText, Mode=TwoWay}"/>

</syncfusion:SfDataGrid.Columns>

We have created a sample to achieve this requirement and please check the following sample link.
