  Thanks Suresh for your code but it will only work if JavaScript is enabled. What's your fallback for when JavaScript is not available? Why don't you do this in server-side code?

  For Example

  <asp:TextBox ID="txtContact" runat="server" MaxLength="30" />
  
  <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtContact"
    Text="*" ErrorMessage="Contact is required" ToolTip="Only supports numeric and -+()" />
  
  <asp:FilteredTextBoxExtender ID="FilteredTextBoxExtender1" runat="server" TargetControlID="txtContact" ValidChars="1234567890-+()" />
  
  <asp:ValidationSummary ID="ValidationSummary1" runat="server" />

  its support letters and-+() only no alphabets or space

  To restrict everything including Blanks and Spaces and to allow only numbers use below Regex

  Regex NumOnly = new Regex("\\A[\\d]\\Z");

  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" Style="z-index: 100; left: 259px; position: absolute;
   top: 283px" ValidationGroup="check"></asp:TextBox>

  
  

  
   <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"></asp:RegularExpressionValidator>

  check out this one..

  its for numbers and some mathematical operators...

  u can remove the mathematical operators if not required..

    <asp:RegularExpressionValidator ID="regular_exp_for_txt_ans" runat="server" 
                  ErrorMessage="Enter digits only" ControlToValidate="txt_answer" 
                  ValidationExpression="^[+-]?\d+(\.\d{1,4})? *%?$" ForeColor="White">*</asp:RegularExpressionValidator>
                   <cc1:ValidatorCalloutExtender TargetControlID="regular_exp_for_txt_ans"
                   ID="ValidatorCalloutExtender1" runat="server">
                  </cc1:ValidatorCalloutExtender>
