Global adgang til strenge

ja du burde godt kunne klare det med :

ValidationExpression="<%$ RegExLib.ValiderCifre%>" />

Men du skal nok lige køre en Page.DataBind();

The following code example shows how to register a custom expression builder in the Web.config file. A custom expression builder must implement the ExpressionBuilder abstract class.

To reference the expression in an .aspx file, use the following sytax:

<asp:Label ID="Label1" runat="server"

Text="<%$ MyCustomExpression:Hello, world! %>" />

Copy Code
<configuration>
    <system.web>
      <compilation>
          <expressionBuilders>
              <add expressionPrefix="MyCustomExpression"
              type="MyCustomExpressionBuilder"/>
          </expressionBuilders>
      </compilation>
    </system.web>
</configuration>
