        {
            if (e.KeyCode == Keys.PageDown)
            {
                int cRow=dataGridView1.CurrentRow.Index;
                cRow += 1;
                dataGridView1.CurrentCell = dataGridView1.Rows[cRow].Cells[0];

            }

hi,

try using the SelectionChanged event of the datagridview. you can use arrow keys to navigate through the records and this event gets fired automatically.

Hope this helps.

I assume what you want to do is trap the Page Down key and use it for navigating the datagridview. The problem in your code is that you are not telling the datagridview that you have aleady handle the key press.

Let it know that you have taken care of the key press by setting the Handled property to true.

If using KeyPress then assign the KeyPressEventArgs e ... e.Handled = true;
if using KeyDown then assign the KeyEventArgs e ... e.handled = true;

This prevents the event from going into the internal key event handler of the DataGridView.
