Property Value

Type: System::String^

Supplemental data about the node that is not displayed. The default value is an empty string ("").

The Value property is used to supplement the Text property by storing any additional data associated with the node. This value is not displayed in the control and is commonly used to store data for handling postback events.

System_CAPS_noteNote

If the Value property contains null, the get accessor returns the value of the Text property. If the Text property, in turn, contains null, Empty is returned.

System_CAPS_noteNote

Nodes at the same level must each have a unique value for the Value property; the TreeView control cannot distinguish between different nodes at the same level that have the same value. In this scenario, if the user clicks a node that has a duplicate value, the node that appears first in the TreeView control is selected.

The value of this property is stored in view state.

The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see LocalizableAttribute and ASP.NET Globalization and Localization.

The following code example demonstrates how to use the Value property to store the key field.
