Tabs can appear rounded, sloped, or rectangular. By default, the tab will appear rounded, but you can change the shape of the tabs to any of the three settings by setting the C1TabControl.TabItemShape property to Rectangle, Rounded, or Sloped.

Rectangle

To change the tab shape, use one of the following methods:

Add TabItemShape="Sloped" to the <c1:C1TabControl> tag so that the markup resembles the following:
