双击datagrid wpf如何找到标题或行

Question

我在wpf应用程序中添加了一个datagrid.

<DataGrid ItemsSource="{Binding Projects}" SelectedItem="{Binding SelectedProject}" MouseDoubleClick="DataGrid_MouseDoubleClick" />

这是我背后的代码

private void DataGrid_MouseDoubleClick(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    if selected row is header
        then do this
    else
        do this
}

现在的问题是我是如何知道哪一个是双击的.它是标题或行.我怎么能找到它.

不是在DataGrid中添加双击事件,而是为DataGridRow和DataGridColumnHeader添加sperate事件.更新了XAML:

<DataGrid ItemsSource="{Binding Projects}" SelectedItem="{Binding SelectedProject}" MouseDoubleClick="DataGrid_MouseDoubleClick"> 
    <DataGrid.Resources>
        <Style TargetType="DataGridRow">
            <EventSetter Event="MouseDoubleClick" Handler="DataGridRow_MouseDoubleClick" />
        </Style>
    </DataGrid.Resources>
    <DataGrid.Resources>
        <Style TargetType="DataGridColumnHeader">
            <EventSetter Event="MouseDoubleClick" Handler="DataGridColumnHeader_MouseDoubleClick" />
        </Style>
    </DataGrid.Resources>
</DataGrid>

这里有代码.

private void DataGridRow_MouseDoubleClick(object sender, System.Windows.RoutedEventArgs e)
{
    // This is when a row is double clicked.
}

private void DataGridColumnHeader_MouseDoubleClick(object sender, System.Windows.RoutedEventArgs e)
{
    // This is when header is double clicked.
}
