TreeNodeBinding::ImageToolTip Property
Gets or sets the ToolTip text for the image that is displayed next to a node to which the TreeNodeBinding object is applied.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System::String^The ToolTip text for the image that is displayed next to a node to which the TreeNodeBinding object is applied. The default is an empty string (""), which indicates that the P:System.Web.UI.WebControls.TreeNodeBinding.ImageToolTip property is not set.
When the TreeView control is bound to a data source, use the ImageToolTip property to specify the value to bind to the ImageToolTip property of a TreeNode object. The text that you specify provides Assistive Technology devices with a description of the image that can be used to make the control more accessible.
This binding relationship affects all TreeNode objects to which the TreeNodeBinding object is applied. When an image is displayed next to a node, the ToolTip text is displayed when the mouse pointer is positioned over the image.
Note |
|---|
You can selectively override the ImageToolTip property by setting the ImageToolTip property of each node directly. |
Instead of using the ImageToolTip property to bind the same ToolTip text to each node image, you can bind the ImageToolTip property of a TreeNode object to a field of a data source by setting the ImageToolTipField property.
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 second code example provides sample XML data for the first code example.
The following example demonstrates how to use the ImageToolTip property to specify the ToolTip text for the image that is displayed next to a node to which the TreeNodeBinding object is applied. For this example to work correctly, you must copy the sample XML data, provided after this code example, to a file named Booklist.xml.
