Combo box events

[gwithey]

Hi i have come across a problem using combo box events

  private void comboBox1\_KeyPress(object sender, KeyPressEventArgs e)
  {
     if (Control.ModifierKeys == Keys.Delete)
     {
        imageViewer1.DeleteSelectedShape();
     }
  }

  private void comboBox1\_MouseDoubleClick(object sender, MouseEventArgs e)
  {
     comboBox1.Text = "hello";
  }

For some reason the above code is not fired, it is probably a simple constraint i do not know about but can anyone see why this is would not fire. Thanx in advance

I suggest you read the documentation on Control.ModifierKeys, your code is not OK. :)

Ah thanx that was a silly mistake. Modifier keys (SHIFT, CTRL, and ALT) not Del The problem is that when run it doesn't make it that far as the events are never fired

Just found a solution so thought i would post it : Most controls don,t fire delete on key press so override command key pressed and check value in keypress

// Override cmd key press
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{

     if (keyData == Keys.Delete)

        OnKeyPress(new KeyPressEventArgs((Char)Keys.Delete));



     return base.ProcessCmdKey(ref msg, keyData);

  }

  private void Form1\_KeyPress(object sender, KeyPressEventArgs e)
  {
     if (e.KeyChar == (Char)Keys.Delete)
     {
        imageViewer1.DeleteSelectedShape();
     }
  }

Thanx for the help George

sounds fair. Some keys are used to support editing, unless you tell the control otherwise. :)

try this: private void textBoxSize_KeyPress(object sender, KeyPressEventArgs e) { if ((e.KeyChar > 47 && e.KeyChar < 58) || e.KeyChar == 8 || e.KeyChar == 13) { /*do something*/ } }
