Question

1)
I develop a c# user control.
In that control, I have a button. When the user clicks the button at runtime, a new control (for example, pictureBox) is created ,next to the previous pictureBox.

I did it that way:

PictureBox pb = new PictureBox();
pb.Location = new Point(oldPb.X, oldPb.Y + 100);
pb.Size = oldPb.Size;
Controls.Add(pb);

The problem is, that I want to be able to manage all of the created items.
I want, for example, to index the pictureBoxes, then get a number from the user and change the photo of the wanted photoBox.
for example:

photoBox3.Image = .......

How can I do it?

2)
I want to be able to recognize when the user clicks on one of those photoBoxes and do an action on the chosen photoBox.
How can I do that?

Thanks

You can use the Tag Property of the PictureBox to store some kind of index.

You can then have all your PictureBoxes respond to a click event:

pb.Click += new EventHandler(picturebox_Click);

and check the Tag there

private void picturebox_Click(object sender, EventArgs e)
{
   PictureBox pb = sender as PictureBox;
   if (pb != null)
   {
     string s = pb.Tag
   }
}
