Question

I am using the WPF Datagrid from Codeplex.

I am able to style the rows and with the following attributes in the dg:DataGrid element.

But how do I style the Headers? I find 100s of examples on the web which define Styles and use e.g. x:Key=’DataGridColumnHeaderStyle’ in the Datagrid element, but none of them seem to work for me.

How can I just e.g. change the Datagrid Header background to orange on this DataGrid?

<dg:DataGrid AlternatingRowBackground='#ddd'      RowBackground='#eee'      Name='theGrid1'      VerticalAlignment='Stretch'      AutoGenerateColumns='False'      BorderBrush='#ddd'> ... </dg:DataGrid>

The style in this case is in a file called generic.xaml it should be loacted in a themems folder in your project.

find it and open it. inside you will find this line that controls the background of the column headers

 <dg:DataGridHeaderBorder SortDirection='{TemplateBinding SortDirection}'                                      IsHovered='{TemplateBinding IsMouseOver}'                                      IsPressed='{TemplateBinding IsPressed}'                                      IsClickable='{TemplateBinding CanUserSort}'                                      Background='{TemplateBinding Background}'                                      BorderBrush='{TemplateBinding BorderBrush}'                                      BorderThickness='{TemplateBinding BorderThickness}'                                      Padding ='{TemplateBinding Padding}'                                      SeparatorVisibility='{TemplateBinding SeparatorVisibility}'                            SeparatorBrush='{TemplateBinding SeparatorBrush}'> 

basically its defined at another place in the template: this will explain TemlateBinding to you MSDN TemplateBinding
