SplitContainer.Panel1 Property

Gets the left or top panel of the SplitContainer, depending on Orientation.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public SplitterPanel Panel1 { get; }

Property Value

Type: System.Windows.Forms.SplitterPanel
If Orientation is Vertical, the left panel of the SplitContainer. If Orientation is Horizontal, the top panel of the SplitContainer.

Use the Panel1 property to configure the left panel of a vertical SplitContainer or the top panel of a horizontal SplitContainer. For example, you can specify the minimum size of the panel by changing the value of the Panel1MinSize property, set the FixedPanel property to Panel1 so that the panel remains the same size when the container is resized, or you can get or set the panel's BackgroundImage and BackgroundImageLayout properties.

You cannot remove Panel1 from the SplitContainer.

NoteNote

If Panel1 or Panel2 contains no control that can receive the focus, the focus remains on the splitter when it is clicked. To change the focus to Panel1 or Panel2, set the TabIndex property of Panel2 to 0 and the TabIndex property of Panel1 to 1.

If Panel1 or Panel2 contains no control that can receive the focus, the focus remains on the splitter when it is clicked. To change the focus to Panel1 or Panel2, set the TabIndex property of Panel2 to 0 and the TabIndex property of Panel1 to 1.
