# How to: Split a Window Horizontally Using the Designer

This example makes the splitter that divides the <xref:System.Windows.Forms.SplitContainer> control horizontal.

> [!NOTE]
> The <xref:System.Windows.Forms.SplitContainer.Orientation%2A> property of the <xref:System.Windows.Forms.SplitContainer> control determines the direction of the splitter, not of the control itself.

## To split a window horizontally

In the **Properties** window, set the <xref:System.Windows.Forms.SplitContainer.Orientation%2A> property of the <xref:System.Windows.Forms.SplitContainer> control to <xref:System.Windows.Forms.Orientation.Horizontal>.
