Manually display context menu

[Kim]

I have read you can use this to manually invoke the context menu.

this.radGridView1.ContextMenuManager.ShowContextMenu(radGridView1.CurrentCell)
)

However, what if you want to display the menu and there are no rows? What do i pass as a parm?

Thanks,

Kim

HI,

I found a way around this.

Hi Kim,

Thank you for writing.

It is good to know that you have found a solution, but keep in mind that if you are displaying the context menu with this expression in the mousedown event, both the default and yours context menus will be shown.

I hope this information helps. Should you have any other questions, I will be glad to assist you.

Fyi, I use this code to determine if the user clicked on a row or not. This prevents both menus from popping up.

private void Grid_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == System.Windows.Forms.MouseButtons.Right)
{
 if (gridViewDocuments.ElementTree.GetElementAtPoint(e.Location) is GridCellElement)
                    {
//grid will show default context menu
                        return;
                    }

//here I can show my custom menu as the grid context menu will not popup.
}
}

Hello Kim,

Thank you for writing back.

There is no need to show the default menu, just show your custom menu like this:

if (e.Button == System.Windows.Forms.MouseButtons.Right)
{
    if (!(radGridView1.ElementTree.GetElementAtPoint(e.Location) is GridCellElement))
    {
        // Show your custom menu here
    }
}

I also have prepared a small sample project to illustrate the code in action

I hope this will be useful. Should you have further questions, I would be glad to help.
