#Property Value
Type | Description |
---|---|
ICommand<Node |
A command that uses custom rules to filter nodes. |
#Remarks
Bind a command to the CustomNodeFilterCommand
property to maintain a clean MVVM pattern. The command works like a CustomNodeFilter event handler and allows you to specify custom filter rules in a View Model.
Use the CustomNodeFilterCommand property to apply a custom filter condition. The custom filter takes priority over the filter criteria applied in a column’s Drop-down Filter or the Automatic Filter Row.
To apply a custom filter condition, create a command that uses custom rules to filter nodes and assign this command to the CustomNodeFilterCommand property. You can use the NodeFilterArgs.Item property to get the processed data source record. The NodeFilterArgs.DefaultVisibility property returns the node’s visibility state based on the applied filter.
To hide or show a node, specify the NodeFilterArgs.Visible property.
