TreeViewNodeFilterEventArgs is the data class for the following events:

• TreeViewControl.CustomNodeFilter

Remarks

Use the CustomNodeFilter event to apply custom rules on how to filter data. The TreeViewControl raises this event for each node. The TreeViewNodeFilterEventArgs.Node property returns the processed node.

To hide or show a node, specify the TreeViewNodeFilterEventArgs.Visible property, and set the TreeViewNodeFilterEventArgs.Handled property to true.

If the TreeViewNodeFilterEventArgs.Handled property is set to false, the node’s visibility is determined by the filter applied to the TreeViewControl.
