Question

Please, what is wrong with this code:

InitializeComponent();
this.KeyDown += new KeyEventHandler(dgvC_KeyDown);

private void dgvC_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyValue == 188)
    {
        System.Media.SystemSounds.Beep.Play();
        e.SuppressKeyPress = true;
    }
    if (e.KeyValue == (int)Keys.Delete)
    {
        MessageBox.Show("323");
    }
}

MessageBox appears twice!

I want to execute some code if comma is pressed and another code if DelKey is pressed on a DataGridView (dgvC).

MessageBox is just for test.

Answer 1

It looks like you have subscribed to the KeyDown event twice.

Remove the line in the .Designer.cs file and the e.SuppressKeyPress will still work.
