[Solved] binding header of the gridviewdatacolumn

[meena]

Hi,

The telerik rad gridview is binded to items source and also has selectedItem binding in MVVM pattern. If I need to change the Header of a particulat GridviewDatacolumn, Binding the header to a property is not displaying the value. Using the normal binding is

Header="{Binding Path=HeaderName}" not  working. Should anything else is tobe added?

Hello Meena,

 


You should keep in mind that the DataContext of the header is not the same as the DataContext of the grid. You have to explicitly of the Header to be the one of grid and afterwards, you may bind the Text property directly to the one defined there:

<telerik:GridViewDataColumn DataMemberBinding="{Binding Property1}">
                    <telerik:GridViewDataColumn.Header>
                        <TextBlock Width="100" Text="{Binding  MyCustomHeaderProperty,Source={StaticResource MyViewModel}}" Foreground="Red"/>
                        </telerik:GridViewDataColumn.Header>
                    </telerik:GridViewDataColumn>

Here MyCustomHeaderProperty is a property of your ViewModel which holds some value, which should be displayed. For example if you want to bind the header outside of the grid you may use the element name binding as proposed in the following online help article.
