WPF datagrid header text binding

Question

The column header of the DataGrid is not a FrameWork element for some reason, and so you cannot use bindings to set things like the header text. Please correct me if that is

Answer 1

BTW, in Silverlight (tested with SL 3.0) you can simply use the Header property as the DataContext for the ControlTemplate set via HeaderStyle (see my related question on SO).

I just tried this solution in WPF 3.5 using the WPF Toolkit DataGrid and it works!

Answer 2

an even better solution would be to set the binding in the header's style and pass the column as the header's dataContext... (or even better: to set up an object representing the header's dataContext and pass it)

see there for a way to do this :

How to set the DataContext on a DataGrid Column Header

Answer 3

I used it to populate the DataGrid Column Header.

Trick is in the binding mode. Its' "Mode" needs to be set to "OneWay". Otherwise it is no good.

Example:

<DataGridTextColumn Binding="{Binding RowData}" Header="{Binding Mode=OneWay, Source={StaticResource spy},Path=DataContext.HeaderText,  FallbackValue= header text}"/>

I used a lowercase fallback value, and the value from DataContext was capitalized to assure me that the resource was not null. Also, the value from DataContext was only showing up for me at run time, during design time it displayed the fallback value. Hope this helps.
