This demo illustrates how to bind TreeList columns to Model fields using lambda expressions.
To enable binding TreeList columns to Model fields using lambdas, it is required to declare the TreeList extension using the ExtensionsFactory.TreeList<RowType> strongly-typed declaration method. This method accepts the TreeListSettings<RowType>object that implements the following specific strongly-typed members.
PreviewField. This method defines a field from which the preview row will retrieve its data.
Columns. This property provides access to a collection of strongly-types columns. This collection exposes the specific Add method that accept the lambda expression that defines a particular model field to which the newly created column will be bound.
The specific Add method overload can also accept the delegate method that returns the column settings object. This overload allows you to add a column with specific settings (see the "Is New" and "Has Attachment" columns in this demo).
Note that the partial View with the TreeList extension does not need to be strongly-typed.
