Hi Stefan, I am also having trouble to do the right click on XAMGRID, not XAMDATAGRID. 

My view is:

<ig:XamGrid

Name="xamRaceDetails"
Margin="5,0,0,0"
Grid.Row="3"
ActiveItem="{Binding SelectedDec, Mode=TwoWay}"
ItemsSource="{Binding Decisions}"
AutoGenerateColumns="False"
Grid.Column="0" Grid.ColumnSpan="5" > 

and here is some ContextMenu 

<ig:XamGrid.ContextMenu >
<ContextMenu >
<MenuItem Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContextMenu}}, Path=DataContext.SaveFavoriteCommand}" Header="Save As Favorite Race" />
<MenuItem Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContextMenu}}, Path=DataContext.RemoveFavoriteCommand}" Header="Remove Favorite Race" />
</ContextMenu>
</ig:XamGrid.ContextMenu>

I want to make the right click--> choose from the ContextMenu and fire the command. Right now it seems I have to LEFT click it first and then right click to pass in database, otherwise simply RIGHT click on cell will not make the ActiveItem change. 

this has confused me for two days and there are very limited posts related to XAMGRID. Please attach a simple solution if possible. 

Thanks, 

David 

Hello David,

I can suggest you handle the XamGrid's PreviewMouseRightButtonDown event and add the following code in its handler:

CellControl cell = Utilities.GetAncestorFromType(e.OriginalSource as DependencyObject, typeof(CellControl), true) as CellControl;
(sender as XamGrid).ActiveItem = cell.Cell.Row.Data;

in order to make the clicked row active.

Hope this helps you.

To Select the Row the following was implemented.

private static void MainXamGridPreviewMouseRightButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
var cell = Utilities.GetAncestorFromType(e.OriginalSource as DependencyObject, typeof(CellControl), true) as CellControl;
var xamGrid = sender as XamGrid;
if (cell == null || xamGrid == null)
{
return;
}

xamGrid.Rows[cell.Cell.Row.Index].IsSelected = true;
}
