Hi,
I have a usercontrol say AddressSearchControl.ascx, applied on a page. There is a textbox named Extended Zip code. I have applied reqular expression on this in usercontrol now I want to apply required field validator on this but I want to apply this on the page only instead of applying on the user control. This textbox renders as "ctl00_DefaultContent_AddressProviderBillingAddress_TextBoxExtendedZipCode". Now plz guide how can I make this textbox mandatory. Plz guide me ASAP instead of telling me as if I have asked a terrible thing :)

Hi,
You can use this for both purpose by adding property.

user control

XML

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="uctextBox.ascx.cs" Inherits="UserControlRegulerExpressionValidator.uctextBox" %>
<table><tr><td> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="TextBox1"
        runat="server" ErrorMessage="RequiredFieldValidator" ValidationGroup="ucval" Enabled="false" ></asp:RequiredFieldValidator></td><td><asp:Button ID="Button1"
    runat="server" Text="Button" ValidationGroup="ucval" /></td></tr></table>

C#

code behind of the user control

C#

protected void Page_Load(object sender, EventArgs e)
       {
           if (MyProperty)
               RequiredFieldValidator1.Enabled = MyProperty;
       }

       public bool MyProperty { get; set; }

Your page code behind

C#

protected void Page_Load(object sender, EventArgs e)
        {
            uctextBox1.MyProperty = true;
        }

simply enable and disable user control reqiured field validator using the property.
