Hi,
I would need to show a userpopup when I right-click on a cell of a datagridview. The popup must appear under the cell.
is there any way to do this?
Currently I am using a context menu to allow the choice of various options.
I would like to use a userpopup as it is necessary to display a long list of values.
Thank you?
Cells are not widgets and don’t have a location or size, they are rendered in the browser by building the HTML using the various cell renderers.
You can use Control.MousePosition.X for the X position, it’s already relative to the screen.
You can calculate the top or bottom of the cell in CellMouseDown like this:
for (int i = this.dataGridView.FirstDisplayedRowIndex; i <= e.RowIndex; i++)
{
bottom+= this.dataGridView.Rows[i].Height;
}
Add the header height.
bottom += this.DataGridView.ColumnHeadersHeight;
Convert to screen.
var loc = this.DataGridView.PointToScreen(new Point(0, bottom));
Show the popup.
popup.ShowPopup(Control.MousePosition.X, bottom);
To align the left position is more complicated since the columns may scroll partially.
