Value
Documentation for this section has not yet been entered.
Remarks
When the System.Web.UI.WebControls.TreeView control is bound to a data source, use the TreeNodeBinding.ImageToolTipField property to specify the field name to bind to the TreeNode.ImageToolTip property of a System.Web.UI.WebControls.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 System.Web.UI.WebControls.TreeNode objects to which the System.Web.UI.WebControls.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.
You can selectively override the TreeNodeBinding.ImageToolTipField property by setting the TreeNode.ImageToolTip property of each node directly.
Instead of using the TreeNodeBinding.ImageToolTipField property to bind the TreeNode.ImageToolTip property of a System.Web.UI.WebControls.TreeNode object to a field, you can set the TreeNode.ImageToolTip property to a fixed value by setting the TreeNodeBinding.ImageToolTip property.
If the data source contains multiple fields, you must first set the TreeNodeBinding.Depth or TreeNodeBinding.DataMember property, or both properties in order to bind to the appropriate field.
The value of this property is stored in view state.
