Notes:
That property may have no effect for some combinations of TabLocation and TabOrientation and only pixel and percentage values are supported.
If DisplayMode is set to multi row and tabs are located at top or bottom and orientation is horizontal, then tabs are stretched to the width of control.
If DisplayMode is set to multi row and tabs are located at left or right and orientation is vertical, then tabs are stretched to the height of control.
If tabs are located at left or right and orientation is horizontal, then default value of 100px is used regardless of content of tabs. If application needs other size, then that property should be set.
