Changing a Cursor and DataGridviewCell events.

Question

Hi,
I am having trouble controlling my cursor behaviour on a forms app. I refer to this pic of part of a DataGridView.
My aim - for the cursor to change to a hand when it is over the trash or edit pics.

I have handled the following events:

         private void dgvBookLibrary_CellMouseEnter(object sender, DataGridViewCellEventArgs e)
        {
            switch (dgvBookLibrary.Columns[e.ColumnIndex].Name)
            {
                case "ColumnDelete":
                case "ColumnAmend": this.Cursor = Cursors.Hand; break;
                default: break;
            }
        }

        private void dgvBookLibrary_CellMouseLeave(object sender, DataGridViewCellEventArgs e)
        {
            switch (dgvBookLibrary.Columns[e.ColumnIndex].Name)
            {
                case "ColumnDelete":
                case "ColumnAmend": this.Cursor = Cursors.Arrow; break;
                default: break;
            }
        }

They work so long as I do not roll over one of the hyperlinks in the grid. As soon as I roll over a hyperlink, the cursor remains an arrow, even when I roll over the two pics.

Any ideas?

Hi Dave,


As kritan said, you do not need mouse leave event. But still there should be another change.


Change the cursor property of datagridview without changing the cursor of the form.


        private void dgvBookLibrary_CellMouseEnter(object sender, DataGridViewCellEventArgs e)
        {
            if ((e.ColumnIndex == 3) || (e.ColumnIndex == 4))
            {
                this.dgvBookLibrary.Cursor = Cursors.Hand;
            }
            else
            {
                this.dgvBookLibrary.Cursor = Cursors.Default;
            }
        }

I take that back, I don't need to handle the CellMouseLeave event. This is my final code (I have a thing for switch statements)

        private void dgvBookLibrary_CellMouseEnter(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex > -1)
            {
                switch (dgvBookLibrary.Columns[e.ColumnIndex].Name)
                {
                    case "ColumnDelete":
                    case "ColumnLendBook":
                    case "ColumnReturn":
                    case "ColumnAmend": dgvBookLibrary.Cursor = Cursors.Hand; break;
                    default: dgvBookLibrary.Cursor = Cursors.Default; break;
                }
            }
        }

Thanks guys.
I found that you do need to handle the CellMouseLeave event, otherwise the cursor remains a hand.

But Niki nailed it by pointing out that I should have been chnaging the DataGridView cursor, rather than the Form cursor. I did not think of that at all.

Works fine now.

Cheers!

 private void dataGridView1_CellMouseEnter(object sender, DataGridViewCellEventArgs e)

        {

            if(e.ColumnIndex == 1)

            {

                this.Cursor = Cursors.Hand;

            }

            else 

            {

                this.Cursor = Cursors.Default;
