I tried the following, an it worked:

made a winform and placed a panel on it.
Than added a Button with somethink like this:

private void button1_Click(object sender, EventArgs e)
      {
          Button btn = new Button();
          btn.Click += new EventHandler(btn_Click);

          panel1.Controls.Add(btn);
      }

      void btn_Click(object sender, EventArgs e)
      {
          MessageBox.Show("Hello World");
      }

Or did you mean someting different?

If you want to, for example, handle the click event of a button on a usercontrol, you should be handling it in the usercontrol code - nit in the form on which ou put the user control.

Similarly,if you want to design the button, you deign it in your user control.

If you want to be able to reuse your user control with, say, a different font on the button, then you need to add a property to your user control (lets call it ButtonFont) and write the Setter and Getter to access the Button's Font property.

If you REALLY want to access the button itself outside of the user control, at runtime e.g. you want code that says

MyUserControl1.OKButton.Text = "Hello";

then you need to set the Button's 'Modifiers' property in the user control to Public - so you can access it. This is not good practice, though, better to hide the button itself, and allow access only to those properties you want to give access to.

Similarly if you want to handle the click event of the button on the user control from within your form, you need to add an event to your user control - raise the event when the button is clicked. Thus the form doesn't know it was necessarily a button click event, just that the user control is telling it that some event has occurred.

For example - if your UC is used to select from a list of items, you might allow the user t double click on an item, selec the itme th click OK,select the item and press enter, click on a linklabel - etc. etc.

By raising a single event from the user control, the 'user' of tat control doesn't need to worry about what caused the event to fire - it just needs to know that it needs to handle the event because it has been raised.

Sorry for the rambling - this is a big subject & it depends on your requirements as to what you need to do for the best.

I have a this case...

using System;
namespace FirstGenericClass
{
public classCounter
{
private int count;

public int Counter
{
get{ return count; }
}
public void Increament()
{
count++;
}
}
}

Here i want to write 2 classes, first one as a query class and the second one as a command class. How do I go about that

What do you want to query , and what do you want to command? So far all you have is an Int32 wrapper that has an increment method...

Good way to alienate yourself. Good luck getting anyone to answer with an attitude like that.

Hi AnyBody help me.....

In my project need a schedule a program with in a clock, so i decided to create
a clock circle and if drag and drop the some program in clock(Circle)that is added
to the particular clock time.so need idea to GUI design , if i drag a program to clock
that program duration only have different color ,like wise all program are displayed different color. And main important is if i need to changr or remove the program means
click that the color and drag and drop to the out sideof the circle, that program will removed from the circle . how can i do this give some idea.... I more expecting from you.

ThankYou

How are you going to determine the program's duration? Surely with a Task Scheduler you can only determine the start time?
Also, what are your plans if two programs coincide - there's no easy way in your plan to implement that.
A traditional clock face is 12 hours, but we have a 24 hour day - so there's another issue.

Not trying to discourage you, it could be an interesting approach, but it may need a little more time thinking about the concept.

Thankyou for replay

The program duration already determined and that duration also maintain the database.
And clock issue was altered. Now we used every one an hour clock so that contain 60
minute. i will create 24 clock and that clock also assigned to the day grid.

Now what we want means The program are assigned to the clock(only for 60 minute).
For Example the programming(For Example consider song) duration is 10 minutes. and commercial break is 2 minutes. like wise fill an hour, if want to change the song means click the corresponding song then drag and drop out side of clock, the song
removed from the clock time that's only we want

Thankyou

Sounds good, with some effort it should work well. Don't forget to write an article to share with the community when you're done.

In the meantime, what specific part of your code is giving you trouble?
