Unselected manner in TreeView . please let me know how can I achive this functionality either from ClientSide or from Server Side.

Hello Manishkumar,

You can use this example that is taken from the Telerik Code Library and change the button with a checkbox. You can also simplify it by removing the RadComboBox and directly finding the RadTreeView in the selectAllNodes and deselectAllNodes JavaScript functions.

Hello Manishkumar,

Try to use set_checked(false) method as described here instead of the uncheck() method.
