Custom Control Event

[Marc Solé]

Hello to everybody.

I have a little problem with a Custom Control that I have created. The thing
is that in my control, when I click a button, it should create another
object in the main form.

My control is located in a TabPage, and I want that when the user clicks a
button, a new tabPage is created, but by now, I don't know how to do that.

Any ideas, suggestions, links are wellcomed.

Many thanks,

Marc

To add a tab page to an existing tab control you need the following :

TabControl tb1;

TabPage tabPage1 = new TabPage();
tabPage1.Text="Tab page1";
tb1.Controls.Add(tabPage1);
Hope this helps..

Regards,
Tasos

Well, to do it /properly/ you need to think about what each object should
legitimately be able to see; your control instance would either need to know
about the tab-control instance somehow, or the code containing your control
needs to catch an event and add the page outside of your control (since the
TabControl is not normally available inside your control - their could be 17
TabControl instances nested on the form for instance; which one do we add
to?).

From your post, the former seems more like what you want? In which case a
property may suffice:

using System;
using System.Windows.Forms;

public class MyControl : UserControl {
public MyControl() {
Button button = new Button();
button.Text = "Click Me";
Size = button.Size;
button.Dock = DockStyle.Fill;
button.Click += new EventHandler(button_Click);
Controls.Add(button);
}
private TabControl _tabControl;
public TabControl ParentTabControl {
get { return _tabControl; }
set { _tabControl = value; }
}
void button_Click(object sender, EventArgs e) {
TabControl tab = ParentTabControl;
if (tab == null) return;
tab.TabPages.Add("New page");
}
}

public class Program {
private static void Main() {

using (Form form = new Form())
using (TabControl tc = new TabControl())
using (MyControl mc = new MyControl())
{
tc.Dock = DockStyle.Fill;
form.Controls.Add(tc);
tc.TabPages.Add("Page1");
mc.ParentTabControl = tc; // key line
tc.TabPages[0].Controls.Add(mc);
form.ShowDialog();
}
}
}
