I'm working on a WinForms app. My ComboBox has DropDownClosed event, but I need to fire this event from a Button. How can I do this?

  • Most of the answers here have function invoke solution and it's probably fine for you but they not answers the question "how to fire event from code". – Logman Jun 02 '16 at 12:13

Like this:

private void button1_Click(object sender, EventArgs e)
{
    comboBox1_DropDownClosed(sender, e);
}

private void comboBox1_DropDownClosed(object sender, EventArgs e)
{
    MessageBox.Show("Test");
}

  • If I want to fire DropDownClosed from within form_load, how can I do this? – Aidin Jun 02 '16 at 07:57
  • @Aidin...In same way. Just call the `comboBox1_DropDownClosed(sender, e);` in your `form_load`. Like this: `private void Form1_Load(object sender, EventArgs e) { comboBox1_DropDownClosed(sender, e); }` – Salah Akbari Jun 02 '16 at 07:58

Please take a look , I believe this is what you are talking about 

 private void abc_Click(object sender, RoutedEventArgs args)
{
}

private void xyz_Click(object sender, RoutedEventArgs args)
{
   abc_Click(sender, args);
}
