BindOnChanged Property

Gets or sets whether the SemanticItem control binds to the target control when its value is changed or when it is confirmed. Read/write.

Usage

Remarks

If BindOnChanged is True, then binding occurs whenever the item's value changes; if False, binding occurs only when the item's value is confirmed.

Example

The following example is based on SASDK Employing Confirmation and Correction Strategies sample.
