right click on multiple rows using C#

[Fang Yan]

I have a question about right-click event handling.

What I want to achieve is selecting multiple rows in data grid first, and then right clicking on them to display a context menu. But what I get right now is all the rows are unselected right after right clicking.

I would appreciate if you could give me a sample code that will allow me to right click on multiple rows, and display a context menu.

I’m using the Essential Suite 2.1.0.9 version.

Thanks a lot!

this.gridDataBoundGrid1.Model.Options.SelectCellsMouseButtonsMask = MouseButtons.Left;

This should prevent the right button from affecting any selections.

Hi,
In my grid I don''t have any function called "gridDataBoundGrid1", or any similar property. So, can you please explain who can I go about it?

Thanks!

Never mind, I think its just the name of the grid. Let me try this.

Thanks

I am having the same problem and while your solution fixes the problem in one way, it does not allow me to get the same behavior as excel. Excel allows me to right click on a cell which makes it active and pops up the context menu. When you right click in the header column of a selected row in excel, it keeps the row selected and pops up the context menu. This is the behavior I would like to have.

You can try handling the SelectionChanging event and canceling it if you are right-clicking in a selection.

That is closer to what I need. However, even if the cell is part of the selection, it still activates the cell (which excel doesn''t do), but it does leave the rest of the selection alone.

You can additionally handle CurrentCellDeactivating to avoid this.

private bool lockForForMouseUp = false;
private void gridControl1_CurrentCellDeactivating(object sender, CancelEventArgs e)
{
	if(lockForForMouseUp)
	{
		e.Cancel = true;
		lockForForMouseUp = false;
	}
	else if(Control.MouseButtons == MouseButtons.Right)
	{
		int row, col;
		Point pt = this.gridControl1.PointToClient(Control.MousePosition);
		if(this.gridControl1.PointToRowCol(pt, out row, out col)
			&& this.gridControl1.Selections.Ranges.AnyRangeContains(GridRangeInfo.Cell(row, col)))
		{
			e.Cancel = true;
			lockForForMouseUp = true;
		}
	}
}
