Hi,

I try to add context menu to Datagrid Header part. Here i find PART_ColumnHeadersPresenterHeadersPresenter from data grid visual tree and add context menu to header. Code given below.

var contextMenu = new ContextMenu();
            contextMenu.Items.Add("Name");
            contextMenu.Items.Add("Age");
            contextMenu.Items.Add("Mark");
            var columnHeadersPresenter = this.SafeFindDescendant<DataGridColumnHeadersPresenter>(ip => ip.Name == "PART_ColumnHeadersPresenter");
            if (columnHeadersPresenter != null)
            {
                columnHeadersPresenter.ContextMenu = contextMenu;
            }</pre>

<DataGrid  x:Name="dg">
            <DataGrid.Columns>
                <DataGridTextColumn Header="name"/>
                <DataGridTextColumn Header="age"/>
                <DataGridTextColumn Header="mark"/>
            </DataGrid.Columns>
        </DataGrid>

But i got context menu on column header only. No context menu on grid header other than column header


My requirement is that , context menu on grid header , not on column header only.

Thanks in advance.
