Allow user to Enter Numbers only With Regular Expression Validator


Hi

try this example :

Only numbers can enter into that Textbox

We can use Regular expression validator for this:
In the validation expression property keep ^\d+$.

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></code><code>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="TextBox1"
ErrorMessage="Please Enter Only Numbers" ValidationExpression=<span style="color: #99cc00;">"^\d+$"</span>></asp:RegularExpressionValidator>

Hope this helps

Good Luck
