You need to create an event in your user control that will fire when you want to tell you form to fire it's function.

(This code is for a usercontrol that adds new items to a database.)

public delegate void AddEventHandler(
    object sender,
    EventArgs e);

public event AddEventHandler AddEvent;

protected virtual void OnAddEvent(EventArgs e)
{
    if (AddEvent != null)
          AddEvent(this, e);
}

Add into the usercontrol code

    OnAddEvent(EventArgs.Empty);

whereever it is appropriate for this event to fire.

Once you get these set up in the usercontrol, then create an event handler in the form.

In the InitializeComponent() in designer generated code, add the event-
this.ctlAddNewRule.AddEvent += new NewRulePanel.AddEventHandler(this.OnAddNewRuleEven t);

and create the handler -

protected void OnAddNewRuleEvent(
    object sender,
    System.EventArgs e)
{
--whatever function code you want the form to perform--
}

Melvik,

I have no idea why you asked me to look at this. I have no knowledge of C#.

That said, the answer you got looks appropriate. In the VB.NET world we would just have a function that handles the event in question. Of course, the event fires as appropriate (EG: Click).

And, quite frankly I don't quite understand what your trying to find out..

Hi there Hovik, you sent me an email asking for my help. Unfortunately I am not a C# programmer so I barely understand your problem, let alone being able to provide you with a solution.

I hope that someone can help you with your code.

Microsoft Press's Visual C#.NET Step By Step Chapter 23 deals with this topic. If you can't get access to this book, have a look at this:

Good luck.

If the button is in the UserControl, then you can go to design and click on the button. In the properties, select the lightening bolt. If you don't already have a button_Click event, then double click on the "Click", and VS will generate the basic function code. You then just add whatever code you need. Probably assign values to the usercontrol properties. Then add the event to notify the parent that the UserControl is done and start the function in the parent.

private void myButton_Click (object sender, System.EventArgs e)
{
  ... your code, if any ...
  OnAddEvent(EventArgs.Empty);
}

In this example, I'm not passing any data, (EventArgs.Empty) because it's in my properties, so I'm just notifying the parent to start it's function, which is

protected void OnAddNewRuleEvent(object sender, System.EventArgs e)
{
   ... the rest of my code ...
}

HTH, Dawn.

Hovic,
I'm in the same boat as Hal and Owain - I'm not a C# programmer - I did one subject at uni in C++ years ago, but that's about as close as I get.

Having said that - it looks like Dawn has solved your problem.
