Try:
int i;
if (!Int.TryParse(myStringToValidate, out i))
   {
   // Failed validation
   }

Hi,

If it's number validation that your referring to, when have a look at the following blog post: Numeric validation in Textbox using regular expressions

From the blog post:

Only numbers can enter into that Textbox
We can use Regular expression validator for this:
Assign the following value to the validation expression property: ^\d+$

<asp:TextBox ID="TextBox1" runat="server" Style="z-index: 100; left: 259px; position: absolute;
top: 283px" ValidationGroup="check">
 
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="TextBox1"
ErrorMessage="Please Enter Only Numbers" Style="z-index: 101; left: 424px; position: absolute;
top: 285px" ValidationExpression="^\d+$" ValidationGroup="check">

Kind regards,
