Default Item

Updated on Jan 20, 2026

The DropDownList enables you to configure its default item.

The defaultItem property type has to match the data type. For example, if the data property contains a list of objects, the defaultItem has to be defined as an object with the same textField and valueField as the data items.

The following example demonstrates how to define a defaultItem as a primitive value (strings, numbers, or other).
