Hi Ralph,
You can try firing a fake click. There is a helper method in Shared that does this for you, Syncfusion.Drawing.ActiveXSnapshot.FakeLeftMouseClick. You could maybe try this in the grid.MouseDown event. You would want to make sure the point is in the grid's corrdinate's system (grid.PointToClient(Control.MousePosition) and pass the grid as the control). Or, you may need to do it in another event.
Please refer this.
