I did post the code above. Here it is again:

private void dgvSchedule_DragDrop(object sender, DragEventArgs e)
{
            DataGridView.HitTestInfo htiSchedule = dgvSchedule.HitTest(e.X, e.Y);
            dgvSchedule.Rows[htiSchedule.RowIndex].Cells[htiSchedule.ColumnIndex].Value = e.Data.GetData(DataFormats.Text);

}

Here, you create an instance "htiSchedule" and get the result of the HitTest() methoud of the DGV to it.

So now htiSchedule contains the information such as the X and Y coordinates of the mouse where it hit the DGV wehn clcking - in turn the cell. So it is quite useful and solved my problem.

 No, the whole thing. Do you mind?

Or do you want explore other alternatives such as sys.preview?

here is a nice tutorial and sample,

OK, here we go.

Lemme know if there are any questions.

Cheers!

 hey, I found a perfect example for you (that is my way of learning new things. Find a working example then go from there).

http://www.codeproject.com/KB/cpp/DataGridView_Drag-n-Drop.aspx

Let me know if that helps.

Thanks mate!

Actually I did come across that and if you look at my code, it's pretty much the same!

Thanks anywayz man.
