Remarks

Use the Name property to determine the unique identifier name for an HtmlInputControl. In this implementation, the get accessor returns the value of the Control.UniqueID property. However, the set accessor does not assign a value to this property.

Note

The set accessor does not assign a value to this property because the Name property must have the same value as the Control.UniqueID property for most controls to work properly.

Classes that inherit from the HtmlInputControl class can override this implementation, if necessary.
