Hello,

I have a web application, that has Masterpage, and a usercontrol inside Masterpage and some pages,

I have a button in one of pages for updating database,

after click button and page refresh, database and masterpage and page updated, but the value in usercontrol doesnt update, and I will refresh page manually to show updated data in usercontroll,

Would you please anyone tell me a solution for fix this issue ?

Hi Arvind Singh Baghel

Its my Masterpage
<form1" runat="server">
<div>

<nav class="navigation">
<div class="wrapper">
<controller:menu runat="server" ID="menu" />
<controller:user runat="server" ID="user" />
div>
nav>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
asp:ContentPlaceHolder>

div>
form>
and its my userControl
<ul class="nav signup">
<li class="no-drop-down">
<asp:Label ID="_signupbutton" runat="server" CssClass="sr">Testasp:Label>
<div class="signup-dropdown">
<asp:PlaceHolder ID="_defaultuser" runat="server" Visible="false">
<div class="notloggeduser">
<asp:LinkButton ID="LinkButton1" runat="server" CssClass="usercontroller" OnClick="LinkButton1_Click" Text="????">asp:LinkButton>
div>
asp:PlaceHolder>
<asp:PlaceHolder ID="_signedup" runat="server" Visible="false">
<div class="defalutuser">
<ul>
<li>
<asp:LinkButton ID="_userlogout" runat="server" CssClass="usercontroller" OnClick="_userlogout_Click">
<i class="fa">?i>????
asp:LinkButton>
li>
ul>
div>
asp:PlaceHolder>
div>
li>
ul>
and this is the code behind usercontrol
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Session["signup"] == null)
{
_signupbutton.Text = "??? ??? / ????";
_defaultuser.Visible = true;
}
else
{
_signupbutton.Text = "? " + Session["signup"].ToString();
_signedup.Visible = true;
}
}
}
protected void _userlogout_Click(object sender, EventArgs e)
{
Session.Remove("signup");
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
Session.Add("signup", "????? ??????????");
}
when I click one of the buttons, lable text doesnt change as session value, after when I refresh the page text chenges.

Hi. You need to refresh the User control. Even if without refreshing the page you can do that by using UpdatePanel. Thanks
