Remarks

The Add method can be used to add a new value to the control’s collection of the property name/value pairs. Alternatively, you can use the ASPxHiddenField.Set method for the same purpose. To delete all values from the control’s collection of property name/value pairs, use the ASPxHiddenField.Clear method. An individual property name/value pair can be removed from the collection by using the ASPxHiddenField.Remove method.

The ASPxHiddenField.Get method is used to obtain the value with the specified property name. Also, the value can be accessed by using the ASPxHiddenField.Item property.

Items from the control’s collection of the property name/value pairs can also be manipulated on the client side by using the following methods: ASPxClientHiddenField.Add, ASPxClientHiddenField.Set, ASPxClientHiddenField.Get, ASPxClientHiddenField.Clear, ASPxClientHiddenField.Remove.
