Hello friends,

Many times we face the Ajax speed problem. Our AJAX page is very slow.

So here I am with  five valuable tips checkout if it helps you some where. 

1)      EnablePartialRendering:-

 Make enable partial rendering = true in script manager

Its syntax is as shown below

“<asp:ScriptManager ID=”scm” runat=”server”  EnablePartialRendering =”true”   >”

It enable partial rendering so use does n’t have to wait a long for page.

<asp:ScriptManager ID=”scm” runat=”server”  EnablePartialRendering =”true”   >


<asp:ScriptReference path=”../Includes/Scripts/System.Web.Extensions/1.0.61025.0/MicrosoftAjax.js”/>



3)      Script Mode=”Release”:-
