TreeNodeBinding.TextField Property
Assembly: System.Web (in system.web.dll)
/** @property */ public String get_TextField () /** @property */ public void set_TextField (String value)
public function get TextField () : String public function set TextField (value : String)
Property Value
The name of the field to bind to the Text property of a TreeNode object to which the TreeNodeBinding object is applied. The default is an empty string (""), which indicates that the TextField property is not set.When the TreeView control is bound to a data source, use the TextField property to specify the field name to bind to the Text property of a TreeNode object. This binding relationship affects all TreeNode objects to which the TreeNodeBinding object is applied. The Text property is used to specify the text displayed in a node.
Note |
|---|
| You can selectively override the TextField property by setting the Text property of each node directly. |
Instead of using the TextField property to bind the Text property of a TreeNode object to a field, you can set the Text property to a fixed value by setting the Text property.
Note |
|---|
| If the data source contains multiple fields, you must first set the Depth or DataMember property, or both properties in order to bind to the appropriate field. |
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 TextField property to specify which attribute of an XML element to bind to the Text property of a TreeNode object to which the TreeNodeBinding object is applied. The second code example provides sample XML data for the first code example.
The following example demonstrates how to use the TextField property to specify which attribute of an XML element to bind to the Text property of a TreeNode object 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.
The following code example provides sample XML data for the preceding code example.
