    Using Generics causes Dispose() error

    I have written a control that does some base functionality. I then wrote a
    control that inherits from it so that I can make several unique versions
    which behave differently. To do this the inherited control uses generics.
    When I compile this code the "Dispose()" routine of my inherited class
    generates a compiler error.

    TestControl.Jun k2.Dispose(bool ): no suitable method found to override.

    Can someone tell me why this is happening and how I can correct it?

    Sample code below.

    namespace TestControl
    {
    public partial class Junk2<T: TestControl.Jun kControl
    {
    T myObject;
    public Junk2(T junk)
    : base()
    {
    InitializeCompo nent();
    myObject = junk;
    }
    }
    }

    namespace TestControl
    {
    partial class Junk2
    {
    /// <summary>
    /// Required designer variable.
    /// </summary>
    private System.Componen tModel.IContain er components = null;

    /// <summary>
    /// Clean up any resources being used.
    /// </summary>
    /// <param name="disposing ">true if managed resources should be
    disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
    if (disposing && (components != null))
    {
    components.Disp ose();
    }
    base.Dispose(di sposing);
    }
    }

      Re: Using Generics causes Dispose() error

      Well its telling you the parent class doesnt have a dispose method marked as
      protected that it can override, if are inheriting from a control i am
      presuming your next class down doesnt have dispose in it and the next one
      down from that does.

          Re: Using Generics causes Dispose() error

          The base class JunkControl inherits from Control and therefore it has its own
          Dispose() routine. It's definition is identical to the Junk2 method. That
          code is autogenerated by the compiler. How do I fix this?

              Re: Using Generics causes Dispose() error

              You got me to looking more. Thanks. What I found was interesting.

              If I create a plan CS code file and create my inherited class it works just
              fine. If I use the "inherit control" method when adding a new item it
              generates that extra Dispose code in the backgroud. I'll use the first
              method for now on.

              Thanks for the help.
