Property Value

Type	Description
ICommand<InitNewNodeArgs>

A command that allows you to initialize a new node with default values.

Remarks

Note

We recommend that you use the AddingNewNodeCommand property instead to initialize a new node with default values.

Bind a command to the InitNewNodeCommand property to maintain a clean MVVM pattern. The command works like an InitNewNode event handler and allows you to initialize a new node in a View Model.

The GridControl executes a command bound to the InitNewNodeCommand property in the following cases:

A user starts to edit the New Item Row.
A user presses the Append button in the Data Navigator.
You call the TreeListView.AddNewNode method / TreeListViewCommands.AddNewNode command.

This command is executed after the GridControl adds a new record to your data source. Use a command bound to the InitNewNodeCommand property to initialize fields in the new record. For example, you can assign a unique value to the key field or assign default field values.
