I've created User Control with my event:

public partial class ucHouse1 : UserControl
  {
    public delegate void MyEngineHandler(int NewIdHouse);
    public event MyEngineHandler IDHouseChanged;
    ...
I run this event:

private void cmbHouses_SelectedIndexChanged(object sender, EventArgs e)
    {
      int var_ID_House = (int)this.cmbHouses.SelectedValue;

      if (IDHouseChanged != null) IDHouseChanged( var_ID_House);
    }

On form where I've added my User Control I work with this exent

private void ucHouse_IDHouseChanged(int NewIdHouse)
    {
      this.MyDataSet.tblCustomer[0].ID_House = NewIdHouse;
    }

All work very good. But when I try to close my form I receive AgumentException in event Dispose of my User Control:

   protected override void Dispose(bool disposing)
    {
      if (disposing && (components != null))
      {
        components.Dispose();
      }
base.Dispose(disposing); // <-- Here I receive AgumentException }

Text of Exception:
Object of type 'System.EventHandler' cannot be converted to type 'ucHouse1+MyEngineHandler'.

What I do not correctly ?

Hi There,

Put in some generic error trapping. Maybe components.Dispose() already cleaned it out, so maybe try catch would work.
