Refresh native grid

I am trying to force a native grid to refresh itself but not having any luck. I have the guid for the grid and have tried calling the refresh method and even invalidate method all to no avail. Any ideas please and thank you.

I have this little snippet saved for refreshing a dashboard:

// click refresh all in baq dashboard
MainController.AppControlPanel.HandleToolClick("RefreshAllTool", new Infragistics.Win.UltraWinToolbars.ToolClickEventArgs(MainController.MainToolManager.Tools["RefreshAllTool"], null));
