Using a variable in regular expression validator

[djtom2000]

Hi,

I am using regular expression validator to carry out some validation and have some code like this:

<asp:regularexpressionvalidator id="regMobileNo" ControlToValidate="txtMobileNo" ValidationExpression="[0-9]{10,15}"

In my aspx.cs page I have added the following line of code to pull my vale from the config, e.g. 4,6

String MobileValidation = ConfigurationSettings.AppSettings["MobileValidation"].ToString();

In the aspx file I want to refer to the variable to dynamically refernce this, e.g. replace 10,15 that is currently hard coded.

How do I do this?

Thanks

protected override void OnInit(EventArgs e)
{
   base.OnInit(e);
   string digits = ConfigurationSettings.AppSettings["MobileValidation"];
   regMobileNo.ValidationExpression = "[0-9]{"+digits+"}";
}
