Form for DevExtreme - Declare DropDownBox in a Form item

This example illustrates how to declare a DropDownBox in an item using templates:

Here, a Form item includes a DropDownBox editor with an embedded DataGrid. To implement validation for the editor and the Form, add the following logic:

• Assign the same validationGroup to the Form and the DropDownBox's Validator. See dxForm.validationGroup and dxValidator.validationGroup
• Then, call the DevExpress.validationEngine.validateGroup(group) method to validate the Form and the DropDownBox.
