I\'ve got a menu that contains, among other things, some most-recently-used file paths. The paths to these files can be long, so the text sometimes gets clipped like \"C:\\
Tooltip is set manually by:
testToolStripMenuItem2.ToolTipText = "My tooltip text";
The MenuItem can for example be part of this menu constellation: a menu strip with a menu item and a sub menu item. (This plumbing code is generated automatically for you in the code behind designer file if you use visual studio)
MenuStrip menuStrip1;
ToolStripMenuItem testToolStripMenuItem; // Menu item on menu bar
menuStrip1.Items.Add(testToolStripMenuItem);
ToolStripMenuItem testToolStripMenuItem2; // Sub menu item
testToolStripMenuItem.DropDownItems.Add(testToolStripMenuItem2)
