How to determine what is under the mouse cursor?
posted

Hello,

I would like to have a contextmenu on my xamdatagrid, and once I made the selection, I would like to see which Row I had right clicked in first place to show to contextMenu for.

This might sound trivial, but in "object sender" I only get to see the ContextMenu itself and not the slected row.  How do I do that please?

<UserControl.Resources>
<ResourceDictionary>
<ContextMenu HasDropShadow="True" x:Key="MassDataSetMenu" DataContext="{Binding Source={x:Static vm:ViewModelLocator.CashflowInputViewModelStatic}}">
<Label Content="Fill-Down" MouseLeftButtonDown="MassDataSetClick"/>
</Label>
</ContextMenu>
<Style TargetType="{x:Type igDP:DataRecordCellArea}" >
<Setter Property="ContextMenu" Value="{StaticResource MassDataSetMenu}" />
</Style>
</ResourceDictionary>
</UserControl.Resources>

 

 

private void MassDataSetClick(object sender, MouseButtonEventArgs e)
{

 

}

    HI,

     Here is a a code snippet 

    void mgrid_PreviewMouseRightButtonDown(object sender, MouseButtonEventArgs e)

    {

     

     

    //throw new NotImplementedException();

     

     

     

     

     

     

     

     

    DependencyObject source = e.OriginalSource as DependencyObject

    ;

     

     

     

    if (source == null) return

    ;

     

     

     

    CellValuePresenter cvp = Infragistics.Windows.Utilities.GetAncestorFromType(source, typeof(CellValuePresenter), true) as CellValuePresenter

    ;

     

     

     

    if (cvp == null) return

    ;

     

     

     

    // get the record cvp.record

    }
