Note: This property is new in the .NET Framework version 2.0.

Gets or sets a value indicating whether lines connecting child nodes to parent nodes are displayed.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public:
property bool ShowLines {
	bool get ();
	void set (bool value);
}
/** @property */
public boolean get_ShowLines ()

/** @property */
public void set_ShowLines (boolean value)

public function get ShowLines () : boolean

public function set ShowLines (value : boolean)

Property Value

true to display lines connecting nodes; otherwise, false. The default is false.

Use the ShowLines property to specify whether the lines that are connecting child nodes to parent nodes are displayed. When this property is set to true, the TreeView control searches the Web-accessible folder that is specified by the LineImagesFolder property for the line images.

NoteNote

If the LineImagesFolder property is not set, the TreeView control will use the built-in, default images (20 x 20 pixels).

The value of this property is stored in view state.

The following code example demonstrates how to use the ShowLines property to display lines connecting nodes in the TreeView control. Be sure to use the Line Designer tool to create a set of line images and place them in a folder named LineImages within the directory for the sample application.

No code example is currently available or this language may not be supported.
