This CompareValidator compares the input control (ControlToValidate) to a specified value (ValueToCompare) or a value in another control (ControlToCompare). Both values will be converted to the data type specified by Type before they are compared. Note that if you set both ValueToCompare and ControlToCompare, the latter will take precedence.

The Operator property specifies the expression that must be met in order for validation to succeed. In other words, ControlToValidate <Operator> ControlToCompare must be true. The compare validator works the same as the System.Web.UI.WebControls.CompareValidator used with full-fledged Web Forms.
