The Key Event Args event data associated with the Key Down and Key Up events provides low-level information about the keystroke, listed in Table 4-6.This information allows you to determine, for example, if an upper- or lowercase character was pressed. Like the Modifiers Key Event Args property, it is of type Keys.The following code example shows how to use this event to validate a row value.To run this example, create a windows form, and add a Gc Multi Row control to the form.Super Validator also provides validation based on the Regular Expressions.You can read more about regular expressions in MSDN starting at following URL: Regular Expression Validator is assigned to input field it looks like this in property grid: Super Validator component includes Comparison Validation that allows you to compare values of two input fields or to compare input field value to a predefined value you set.

Keyboard events provide access to this type of functionality.

That is done by setting Validation Type property as shown in image below: These properties allow you to define 3 level validation for each control.

Validation starts with Validator1, Validator2 and finally Validator3.

Next step is to choose the way Super Validator performs validation.
