hOW to stop page refreshing in

normally in when you clicks on a button or post the page entire page get posted on the server and return back to the client browser.

To avoid this you can use AJAX

put the button or control inside the UPDATEPANEL Which make page post.
and put the part of the page in UPDATEPANEL which will get changed.

By Using this instead of Entire Page post only required part of the page will get changed.3


<asp:ScriptManager ID="ScriptManager1" runat="server">

<asp:updatepanel id="UpdatePanel1" runat="server" xmlns:asp="#unknown">
<asp:label id="Label1" runat="server" text="Label">
<asp:button id="Button1" runat="server" text="Upload" onclick="btnUpload_Click" />

Label1.Text = DateTime.Now.ToString();
