i have written a code on KeyDown event like this

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
     if (e.Alt == true && e.KeyData == Keys.V)
     {
          label4_Click(sender, e);
     }
     else if (e.Alt == true && e.KeyData == Keys.U)
     {
          label5_Click(sender, e);
     }
}

I would like to know when i select Alt & V or U together why is the code not executing?

Note:KeyPreview=true (Form's Property)

Thanks in advance

Set a breakpoint with the debugger.
But what is supposed to happen when a Label is clicked?

sir, when the label is clicked a form should be opened and i have debugged it but it is not going inside both the scopes.

Solution 1

you need to use KeyEventArgs.KeyCode Property[^]

C#

if(e.KeyCode == Keys.V && e.Alt )
{
  label4_Click(sender, e);
}
if(e.KeyCode == Keys.U && e.Alt )
{
  label5_Click(sender, e);
}
