Run javascript function after Postback

You can use endRequest event of PageRequestManager.

<form id="form1" runat="server"><div>    <asp:ScriptManager ID="ScriptManager1" runat="server" />    <asp:UpdatePanel ID="UpdatePanel1" runat="server">        <ContentTemplate>               <asp:Button runat="server" Text="Button" />        </ContentTemplate>    </asp:UpdatePanel></div></form><script type="text/javascript">    var prm = Sys.WebForms.PageRequestManager.getInstance();    prm.add_endRequest(function (s, e) {        alert('Postback!');    });</script>

You can use the ClientScriptManager to make a call to a function on the reload:

ClientScriptManager.RegisterStartupScript(this.GetType(), "AKey", "MyFunction();", true);

Simply

<script type="text/javascript">     function pageLoad() {   } </script><asp:ScriptManager runat="server" /><asp:UpdatePanel runat="server">   <ContentTemplate>     <asp:Button runat="server" ID="Button1" />     <asp:Literal runat="server" ID="TextBox1" />  </ContentTemplate> </asp:UpdatePanel>

pageLoad() will then continue to be called each time Button1 is triggered
