Hi Nicolas, 

So, as you may know we added a ContextMenu in our 9.2 release. 

If you simply want to display a ContextMenu when somone left clicks on a RowSelector, you can use the following code: Which uses the RowSelectorClicked event. 

XamWebContextMenu xwc;

            public MainPage()

            {

                  InitializeComponent();

                  xwc = new XamWebContextMenu();

                  xwc.Items.Add("Copy");

                  xwc.Items.Add("Paste");

                  ContextMenuManager manager = new ContextMenuManager();

                  manager.ContextMenu = xwc;

                  ContextMenuService.SetManager(this.DataGrid1, manager);

           }

            private void DataGrid1_RowSelectorClicked(object sender, Infragistics.Silverlight.RowSelectorClickedEventArgs e)

            {

                  xwc.IsOpen = true;

            }

You can also use the CellClicked event for displaying your alternate menu. Now, the code i have here is simplified.   You'll probably want to create another menu, and make the manager a member variable, so that you can switch out the Contextmenu on the manager in the event that you're displaying the menu. 

Now, if you want to display the menu for a right click, you'll have to use a different approach. 

You can use the Opening event of the XamWebContextMenu: 

<igMenu:ContextMenuService.Manager>

                        <igMenu:ContextMenuManager OpenMode="RightClick" >

                              <igMenu:ContextMenuManager.ContextMenu>

                                    <igMenu:XamWebContextMenu Opening="xwc_Opening">

                                          <igMenu:XamWebMenuItem Header="Copy"></igMenu:XamWebMenuItem>

                                          <igMenu:XamWebMenuItem Header="Paste"></igMenu:XamWebMenuItem>

                                    </igMenu:XamWebContextMenu>

                              </igMenu:ContextMenuManager.ContextMenu>

                        </igMenu:ContextMenuManager>

                  </igMenu:ContextMenuService.Manager>

void xwc_Opening(object sender, Infragistics.Silverlight.OpeningEventArgs e)

            {

                  List<RowSelectorCellControl> rowSelectors = e.GetClickedElements<RowSelectorCellControl>();

                  if (rowSelectors.Count > 0)

                  {

                        // RowSelector

                        return;

                  }

                  List<CellControl> normalCells = e.GetClickedElements<CellControl>();

                  if (normalCells.Count > 0)

                  {

                        // Normal Cell

                        return;

                  }

                  e.Cancel = true;

            }

Now, in order for the right click menu to work, you need to make sure that the Silverlight Plugin has it's windowless property set to true:

<object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">

<param name="windowless" value="true" />

Actually,

What I'm trying to do is copy/paste operations inside the same xamWebGrid. (without using the clipboard)

I'm trying to do this with a context menu. I want to add a context menu when a Row Selector is clicked (eg Copy Row) and a different context menu when a regular Cell is clicked (eg Copy Cell)

Can you help me with an approach for doing this ?

Thanks,

Nicolas
