How to set the SelectedItem based on right mouse click.
posted

I have a context menu set up on the xamDataGrid. When I right click I would like the Records that I right clicked on to be the one and only SelectedItem.

Thanks,

Rod

    Hi Rod -
     
    I would listen to the PreviewMouseRightButtonDown event and execute the following code.  Note: The GetAncestorFromType is a handy method in our shared assembly that lets you find an ancestor element by type.  Also - the code below assumes that FieldLayout.Settings.SelectionTypeRecord is set to Single (since you only want 1 record selected at a time)
     

    void xamDataGrid1_PreviewMouseRightButtonDown(object sender, MouseButtonEventArgs e)

    {

    DependencyObject source = e.OriginalSource as DependencyObject;

    if (source == null)

    return;

    DataRecordPresenter drp = Infragistics.Windows.Utilities.GetAncestorFromType(source, typeof(DataRecordPresenter), true) as DataRecordPresenter;

    if (drp == null)

    return;

    if (drp.Record != null)

    {

    drp.Record.IsSelected = true;

    drp.IsActive = tru;

    }

    }
