How to keep the selection range while showing the contextmenu?

[Dongxian Li]

I want to select a range of cells using left mouse button dragging over the cells and then pressing down the right mouse button to show a context menu according to the selected range type. To my surprise, the selection disappeared once you press the right mouse button.
How can you keep the selection range there while showing the contextmenu?

There is a property that controls which mouse button(s) control selecting cells. Try setting

this.gridControl1.Model.Options.SelectCellsMouseButtonsMask = MouseButtons.Left;

to see if this does what you want.
