How can I detach an event from a control?

  • 772

I am working on filling in the fields of a form and I have one ComboBoxthat refers to the sales staff and I have the associated event SelectedIndexChangedthat triggers a search after changing the value. What I want is to prevent that event from being triggered, because when doing the Loadform in a first load I get an error when trying to do the associated search, since it ComboBoxdoes not yet have a valid value. Thank you very much.

    I can do like this:

    combobox1.SelectedIndexChanged -= combobox1_SelectedIndexChanged;

    ...and reconnect it later like this:

    combobox1.SelectedIndexChanged += combobox1_SelectedIndexChanged;

    Of course, in this case, you must have an event like this:

    private void combobox1_SelectedIndexChanged(object sender, EventArgs e)
{
   . . .
}
