    Select Box

    Overview

    The SelectBox component allows users to select an item from a drop-down list. This demo illustrates the following SelectBox properties:

    • items
      Specifies an array of items displayed in the SelectBox.
    • placeholder
      Specifies the text that is displayed when no items are selected.
    • readOnly
      Prevents users from changing the editor's value via the UI.
    • disabled
      Specifies whether the SelectBox responds to user interaction.
    • dataSource
      Binds the SelectBox to data. Unlike the items property, dataSource accepts the DataSource object that allows users to sort, filter, group, and shape data.
    • fieldTemplate and itemTemplate
      Allow you to customize the text field and drop-down list items.
    • onValueChanged event handler
      Use this function to perform an action when a user chooses a new value. In this demo, this function is used to display the selected value.
