Class \Prado\Web\UI\WebControls\TCompareValidator
TCompareValidator compares the value entered by the user into an input control with the value entered into another input control or a constant value. To compare the associated input control with another input control, set the \Prado\Web\UI\WebControls\setControlToCompare property to the ID path of the control to compare with. To compare the associated input control with a constant value, specify the constant value to compare with by setting the \Prado\Web\UI\WebControls\setValueToCompare property.
The \Prado\Web\UI\WebControls\setDataType property is used to specify the data type of both comparison values. Both values are automatically converted to this data type before the comparison operation is performed. The following value types are supported:
- Integer A 32-bit signed integer data type.
- Float A double-precision floating point number data type.
- Date A date data type. The format can be specified by the \Prado\Web\UI\WebControls\setDateFormat property
- String A string data type.
Use the \Prado\Web\UI\WebControls\setOperator property to specify the type of comparison to perform. Valid operators include Equal, NotEqual, GreaterThan, GreaterThanEqual, LessThan and LessThanEqual.
