Question

Is there any easy (5 lines of code) way to do this?

Answer 1

The shortest code to delete the tab the middle mouse button was clicked on is by using LINQ.

Make sure the event is wired up

this.tabControl1.MouseClick += tabControl1_MouseClick; 

And for the handler itself

private void tabControl1_MouseClick(object sender, MouseEventArgs e) {   var tabControl = sender as TabControl;   var tabs = tabControl.TabPages;    if (e.Button == MouseButtons.Middle)   {     tabs.Remove(tabs.Cast<TabPage>()             .Where((t, i) => tabControl.GetTabRect(i).Contains(e.Location))             .First());   } } 

And if you are striving for least amount of lines, here it is in one line

tabControl1.MouseClick += delegate(object sender, MouseEventArgs e) { var tabControl = sender as TabControl; var tabs = tabControl.TabPages; if (e.Button == MouseButtons.Middle) { tabs.Remove(tabs.Cast<TabPage>().Where((t, i) => tabControl.GetTabRect(i).Contains(e.Location)).First()); } };
