the control which is causing postback, did you wrap that control with update panel?

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="Elvatra.test" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

try this:

ASP.NET

<asp:updatepanel id="upd" runat="server">
      <contenttemplate>
          <asp:textbox id="TextBox1" runat="server"></asp:textbox>
          <asp:button id="Button1" runat="server" text="Button" />
          <asp:requiredfieldvalidator id="RequiredFieldValidator1"
                                      runat="server"
                                      ControlToValidate="TextBox1"
                                      ErrorMessage="RequiredFieldValidator">
          </asp:requiredfieldvalidator>
    </contenttemplate>
  </asp:updatepanel>

Good luck

your code is wrong dear, please check your code. you haven't closed the update panel. also your contenttemplate tag is missing. match your code with this solution properly you will get to know where have you done wrong.

i think you don't understand my problem,
dear Reje, when i use validation controls, they doesn't work and page refresh.

Raje_ 8-Mar-13 6:07am

that's what I am telling, Check carefully in my solution, how I have wrapped all the controls inside UpdatePanel. Or you can just copy my solution and paste it after your scriptmanager tag.

hamid-shrk 8-Mar-13 6:09am
