Property Value

Type	Default	Description
Boolean	false	true to allow the item to submit a form; otherwise, false.

Remarks

You can use a toolbar item to submit a form. This behavior is equivalent to the type=”submit” HTML button’s behavior.

To create a similar toolbar item, follow the steps below:

1. Place the Toolbar component’s markup inside an EditForm.

2. Define a data model with data annotation attributes. For more information, refer to the following help topic: Validate Input.

3. Set the item’s SubmitFormOnClick property to true.
