Sorry for bringing back to life this post but i found it just now…

Couldn’t this be done using the EditingControlShowing event?

i.e.:
private void mydatagrid_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
// set hand cursor only for button column types
if (!(e.Control is Button)) return;

e.Control.Cursor = Cursors.Hand;
}

Just a thought…

That’s funny Veljko, I was about to post the same thing.

The CellMouseEnter and CellMouseLeave are a bit more effective in performance because the event is not so frequently fired as CellMouseMove.
The glitches you receive is probably because you declared both events and in both placed the ‘else’ branch – this is a bit of a problem because both events fire when mouse is moved from one cell to another. So, the sufficient code should be:
private void grd_CellMouseEnter(….)
if (CheckIsClickable(e.RowIndex, e.ColumnIndex))
{
this.Cursor = Cursors.Hand;
}

private void grd_CellMouseLeave(….)
if (CheckIsClickable(e.RowIndex, e.ColumnIndex))
{
this.Cursor = Cursors.Default;
}

I’ve tried this and works just fine…

(The CheckIsClickable is my method that returns true or false based on the current row and column index – columns that hold clickable cells and rows that have data (i.e. > 0 and < grd.Rows.Count))
