Question

I am trying to take text from a list box control and put it into a particular cell in a data Grid. I am using the following code:

    private void DG_DragDrop(object sender, DragEventArgs e)
    {
        DataGridView.HitTestInfo theHit = DG.HitTest(e.X, e.Y);
        int theCol = theHit.ColumnX;
        int theRow = theHit.RowY;
        MessageBox.Show(theCol.ToString() + " " + theRow.ToString());

    }

By the column and row coordinates are always -1. I suspect the X and Y coming in need to be adjusted somehow, but I am not sure how or if this is the problem. Any ideas or suggestions would be appreciated…

I found the answer, here is the code in case anyone else has a similar problem:

   Point theLoc = DG.PointToClient(new Point(e.X, e.Y));

        DataGridView.HitTestInfo theHit = DG.HitTest(theLoc.X,theLoc.Y);
        int theCol = theHit.ColumnIndex;
        int theRow = theHit.RowIndex;
        MessageBox.Show(theCol.ToString() + " " + theRow.ToString());
