ASP.NET: Ajax UpdatePanel issue - asp.net

Question

I am supposed to update the progress & display the corresponding message on the client side while the function is still under execution at server side.
How can I achieve this?
The function looks like:
protected void Button1_Click(object sender, EventArgs e)
{
string Result = "Success";
if (Result == "Success")
{
Label1.Text = "Plan mst Completed";
Thread.Sleep(2000); //Some functionality here
Label1.Text = "Packing date mst Started";
}
if (Result == "Success")
{
Label1.Text = "Packing date mst Completed";
Thread.Sleep(2000); //Some functionality here
Label1.Text = "Etd mst Started";
}
if (Result == "Success")
{
Label1.Text = "Etd mst Completed";
Thread.Sleep(2000); //Some functionality here
Label1.Text = "Inner box mst Started";
}
}
And I have to update the text of Label1 while the above function is still under execution.
I have tried using AJAX (although I'm still a beginner), but with no success. Here's what I did:
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Timer ID="Timer1" runat="server" Interval="10" ontick="Timer1_Tick1">
</asp:Timer>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
</form>
And the corresponding events:
protected void Page_Load(object sender, EventArgs e)
{
UpdatePanel1.UpdateMode = UpdatePanelUpdateMode.Conditional;
}
protected void Timer1_Tick1(object sender, EventArgs e)
{
UpdatePanel1.Update();
}
Any other alternatives other than AJAX such as via jQuery or otherwise are also welcome.
