Hai, For username and password You use Requiredfield validator this is a basic and most used one. For phone number use Regular expression validator this will check whether the give number is number/phonenumber.It raise an when u use character or any other special symbols. using Required field is easy just place it near username textbox and set the property "controltovalidate" as username textbox name for eg:txtuser.Continue same for password When u use regularexpression validator we need to use a regular expression. Set Expression property as ^[0-9]{10} Try this. R.SURESH

this is for username and password fields,

 <asp:TextBox ID="UserName" runat="server" Font-Size="0.8em"></asp:TextBox>
                                        <asp:RequiredFieldValidator ID="UserNameRequired" runat="server" ControlToValidate="UserName"
                                            ErrorMessage="User Name is required." ToolTip="User Name is required." ValidationGroup="Login1">*</asp:RequiredFieldValidator>

this is for phone number,


<asp:TextBox ID="txtqty" runat="server" TabIndex="6" MaxLength="10" AutoCompleteType="Disabled"></asp:TextBox>
                                <asp:RequiredFieldValidator ID="Rfvquty" runat="server" ControlToValidate="txtqty" 
                                    ErrorMessage="Enter the Material Quantity" ForeColor="Red" SetFocusOnError="True" InitialValue="0"
                                    ValidationGroup="valnewmaterial">*</asp:RequiredFieldValidator>
                                <asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server" ControlToValidate="txtqty" 
                                    ErrorMessage="Please Enter Only Numbers" ValidationExpression="^\d+$" ValidationGroup="valnewmaterial">*</asp:RegularExpressionValidator>
