TreeNodeBinding.NavigateUrl Property

Gets or sets the URL to link to when a node to which the TreeNodeBinding object is applied is clicked.

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

public string NavigateUrl { get; set; }

Property Value

Type: System.String
The URL to link to when a node to which the TreeNodeBinding object is applied is clicked. The default is an empty string (""), which indicates that the NavigateUrl property is not set.

When the TreeView control is bound to a data source, use the NavigateUrl property to specify the URL to bind to the NavigateUrl property of a TreeNode object. This binding relationship affects all TreeNode objects to which the TreeNodeBinding object is applied. When this property is set, the TreeView control displays a hyperlink for the text of the node, instead of plain text. You can also optionally set the Target property to specify the window or frame in which to display the linked content.

NoteNote:

You can selectively override the NavigateUrl property by setting the NavigateUrl property of each node directly.

Instead of using the NavigateUrl property to bind the same URL to each node, you can bind the NavigateUrl property of a TreeNode object to a field of a data source by setting the NavigateUrlField property.

The value of this property is stored in view state.

This section contains two code examples. The first code example demonstrates how to use the NavigateUrl property to specify the URL to link to when a node to which the TreeNodeBinding object is applied is clicked. The second code example provides sample XML data for the first code example.

The following code example demonstrates how to use the NavigateUrl property to specify the URL to link to when a node to which the TreeNodeBinding object is applied is clicked. For this example to work correctly, you must copy the sample XML data, provided after this code example, to a file named Booklist.xml.
