Question Regular Expression

[soni_1985]

I want to enter only characters in textbox not numbers.For dat I use Regular Expression Validator,But even after dat numbers are entering.

 <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></td>
                     <asp:RegularExpressionValidator ID="regexpName" runat="server"     
                                    ErrorMessage="This expression does not validate." 
                                    ControlToValidate="TextBox1"     
                                    ValidationExpression="^[a-zA-Z'.\s]{1,40}$" />

Your ValidationExpression is ok but RegularExpressionValidator is not designed to prevents entering of numbers.

Rather you should use a bit JavaScript for that. Just check the textbox's onkeyup event and if it's number cancel it.
