Gets or sets the target window or frame in which to display the Web page content that is associated with a node to which the TreeNodeBinding object is applied.
Assembly: System.Web (in System.Web.dll)
Property ValueType: System.String
The target window or frame in which to display the linked Web page content. Values must begin with a letter in the range of A through Z (case insensitive), except for certain special values that begin with an underscore, as shown in the following table.
Renders the content in a new window without frames.

Renders the content in the search pane.
Renders the content in the frame with focus.
Renders the content in the full window without frames.
Check your browser documentation to determine if the _search value is supported. For example, Microsoft Internet Explorer version 5.0 and later supports the _search target value.
The default is an empty string (""), which refreshes the window or frame with focus.
When the TreeView control is bound to a data source, use the property to specify the value to bind to the Target property of a TreeNode object. This binding relationship affects all TreeNode objects to which the TreeNodeBinding object is applied. The Target property is used to specify the window or frame in which to display the Web content that is linked to a node when that node is clicked.
Setting the Target property of the TreeView control for the nodes to which the TreeNodeBinding object is applied. You can selectively override the property by setting the Target property of each node directly.property overrides the
When creating accessible Web pages, you should avoid using the NIB: ASP.NET Accessibility.property to target another window. For more information, see
The value of this property is stored in view state.
This section contains two code examples. The first code example demonstrates how to use theproperty to specify that the Web page that is associated with the root node should be displayed in a new window. The second code example provides sample XML data for the first code example.
The following example demonstrates how to use theproperty to specify that the Web page that is associated with the root node should be displayed in a new window. For this example to work correctly, you must copy the sample XML data, provided after this code example, to a file named Book.xml.
