TreeNode.ShowCheckBox Property
Assembly: System.Web (in system.web.dll)
public: property Nullable<bool> ShowCheckBox { Nullable<bool> get (); void set (Nullable<bool> value); }
/** @property */ public Nullable<boolean> get_ShowCheckBox () /** @property */ public void set_ShowCheckBox (Nullable<boolean> value)
public function get ShowCheckBox () : Nullable<boolean> public function set ShowCheckBox (value : Nullable<boolean>)
Property Value
true to display the check box; otherwise, false.The TreeView control allows you to display a check box next to a node's image. Use the ShowCheckBox property to show or hide the check box for the current node.
Although the ShowCheckBox property can be used to display check boxes, it is more common to use the TreeView.ShowCheckBoxes property of the TreeView control. The TreeView.ShowCheckBoxes property, however, affects every node type specified by the property; therefore, the TreeNode.ShowCheckBox property is often used to override that setting for an individual node.
The value of this property is stored in view state.
The following code example demonstrates how to use the ShowCheckBox property to programmatically show and hide the check box for a node in the TreeView control. For this example to work correctly, you must copy the sample XML data below to a file named Book.xml.
The following code is sample XML data for the previous example.
