    The easiest way for achieving the desired result is by setting the MinValue and MaxValue properties of the GridNumericColumn, which will automatically enable the range validation:
        <telerik:GridNumericColumn DataField="Age" MinValue="0" MaxValue="100"></telerik:GridNumericColumn>

    As for displaying error message, this could be achieved with custom validator control. You can refer to the following demo, where you will see how RequiredFieldValidator is used, but in your case you will need CustomValidator:
