Did you try using the MouseClick event of your control? In the handler you can write code like

If (e.Button == Mousebuttons.Middle)
{
     // Your code here
}

 

by: kaufmedPosted on 2008-12-27 at 17:25:15ID: 23250060

Just in case you don't already know, you can dynamically add a handler by using code like

yourTabControl.MouseClick += new MouseEventHandler(your_Handlers_name_here)j

but how can I tell on which tabPage the click happened ?

 

by: kaufmedPosted on 2008-12-27 at 22:24:41ID: 23250640

The sender object of your event handler should be the tabPage. You will have to cast it to use its methods/properties:

Example:

        private void Form1_MouseClick(object sender, MouseEventArgs e)
        {
            TabPage tp = (TabPage)sender;
 
            if (e.Button == MouseButtons.Middle)
            {
 
            }
        }

I am a bit lost -
you placed the event handler on the form ? and the sender is the TabPage ?
will the sender not be the Page ?

 

by: kaufmedPosted on 2008-12-28 at 18:33:13ID: 23253682

I'm sorry. That example does seem confusing now that I look at it.

The name of the event handler is arbitrary--you can name your event handler whatever you want as long as you add it to handle the event. The code you should be concerned with is in the snippet. Put that code in your event handler for the TabPage.

TabPage tp = (TabPage)sender;

And I was just copy-and-pasting from my test solution...  The code I was testing in just happened to be in Form1_MouseClick...  You can disregard.

 

by: SnowFlakePosted on 2008-12-30 at 10:22:36ID: 23264593

Sorry,I can't get it to work. The event does not even fire.

At least not when I click the tip of the tab ( I don't have access the the client area of the TabPage as it is covered by a splitContainer that has other controls inside it - but that should not matter as I am interested in catching the clicks on the tips of the tabPages).

I can get a tabControl1_MouseClick event to fire
but the the handler is the tabControl and I don't know what tabPage was clicked.

 

by: SnowFlakePosted on 2008-12-30 at 14:06:27ID: 23266566

finally I got it working.

		private void tabControl1_MouseClick(object sender, MouseEventArgs e) {
			if (e.Button == MouseButtons.Middle) {
				for (int i = tabControl1.TabPages.Count-1; i >= 0; i--) {
					if (tabControl1.GetTabRect(i).Contains(e.Location)) {
						(sender as TabControl).TabPages.Remove((sender as TabControl).TabPages[i]);
						break;
					}
				}
				
			}
		}
