MessageBox.Show(comboBox1.GetItemText(comboBox1.Items[i]));
}

i don't think that it is possible to iterate
through foreach becouse i didn't found any
class for combobox items.

In a combo box the items are just strings so you can do this:
foreach (string itm in comboBox1.Items)
{
MessageBox.Show(itm);
}

Not always true.
The Items property is an ObjectCollection because you can stuff whatever you want in the collection, and render the Items yourself in a custom drawing routine. It's usually strings, but not always.

Very true.
Of course HOPEFULLY if you have stuffed something else in there you know what it is and can write the appropriate foreach loop. And if not I guess you can always treat everything in there as an object and write the foreach loop that way.
Guess I need to be a bit clearer around here with all you guru's watching !
Thanks!

The comment wasn't so much for you; it was intended for people who are less well informed who may read the thread later. I don't usually presume to correct MCSDs.
Share and enjoy.

Please use punctuation to separate the sentences from each other. It would make what you write much easier to understand. (Perhaps you should have someone look at your keyboard too, the question mark key seams to get stuck.  )
The methods exist only once in memory.

I have a treeview which lists all the chapters of a book. Whenever the treeView is selected, the program is supposed to paint the text of the entire chapter onto a tabpage.
*******************************************************************************
private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
// a query is run here to produce a result of text from a certain chapter and then import it to a chap_lines string array
tabPage1.Paint += new PaintEventHandler(tabPage1_Paint);
}
private void tabPage1_Paint(object sender, PaintEventArgs e)
{
y = 8;
Graphics g = e.Graphics;
foreach (string line in chap_lines)
{
g.DrawString(line, new Font("Courier New", 10, System.Drawing.FontStyle.Regular), new SolidBrush(Color.Black), 3, y);
y = y+20;
}
}
*******************************************************************************
The problem is that the text is not painted until the next chapter node is selected. Chapter 1 is okay as it is the default node. But if I then select chapter 3, those text of chapter 1 stay there. The text of chapter 3 is not displayed until another chapter is selected.
The thing is when I debug the program setting the breakpoint at "tabPage1.Paint += new PaintEventHandler(tabPage1_Paint)", it gives me the correct result. But if I set the breakpoint anywhere in the tabPage1_Paint event, it can never get out of itself. Why is that?
How can I display its correct text once a chapter is selected?
Also, I have set the tabPage1.AutoScroll to true but it still doesn't scroll to display those lines that are not visible to the tabPage1 area.

Don't add the eventhandler to the paint event from the AfterSelect event. That should be done only once, preferably in the Load event. Now you are adding a new handler every time you select a chapter, which means that the tablPage1_Paint will be called multiple times whenever the control needs to be redrawn.
To cause a control to be redrawn, you use the Invalidate method of the control.

Thanks!
But I want the user to choose what chapter they want to read. If I put the eventhandler in the Load event, it would happen only once??? Well, I think I can do it for the 1st chapter (as default page) but how about the rest of the chapters?

You are confusing hooking up an event with using an event.
Adding an event handler will hook up the method to the event, but it will not call the method. If you do this more than once, the event will contain more than one hook to the same method. That means that every time the event is used it will call the method more than one time.
The paint event is used automatically whenever the control needs to be redrawn. You don't use the paint event yourself. If you need the control to be redrawn you use the Invalidate method to tell the system to redraw the control.
