Sets or retrieves the data type that the values being compared are converted to before the comparison is made.

Inline	<asp:validator type = strDataType ... >
Script	Validator.Type [ = strDataType ]

strDataType

String specifying one of the ValidationDataType values.

The property is read/write with a default value of String.

Exception Type	Condition
ArgumentException	The given value is not one of the ValidationDataType values.

Use the Type property to specify the data type used for comparison. The Type property is used differently by the various comparison validation controls.

For example, in the RangeValidator control, all values being compared ( the upper bound, lower bound, and value of the input control ) are converted to the specified data type before any comparison is performed.

However, if you use a CompareValidator control and set its Operator property to DataTypeCheck, only the value of the input control is converted to the specified data type.

If the value of the input control associated with the validation control cannot be converted to the specified data type, validation fails. The IsValid property of the validation control is set to false.

The following table lists the values that you can use for the Type property.

Data Type	Description
String	Specifies a string data type.
Integer	Specifies a 32-bit signed integer data type.
Double	Specifies a double precision floating point number data type.
Date	Specifies a date data type.
Currency	Specifies a monetary data type.

The following example demonstrates how to use the Type property to specify the data type that values being compared are converted to before the comparison is made.
