Hi friend,
To add the history point in Asynchronous call you can set EnableHistory
propery of ScriptManeger to true.
This event is raised during asynchronous postbacks automatically when the
server-side history state changes.
Refer the following code snippet
<asp:ScriptManager ID="SM1" runat="server"
EnableHistory="true" OnNavigate="SM_Navigating" />
<script runat="server">
private void DoTheAjaxWork(string step)
{
if (SM1.IsInAsyncPostBack && !SM1.IsNavigating)
{
// perform all your real work here and add the history point
SM1.AddHistoryPoint("historyPoint", step, "Step " + step);
}
else
{
txtBox1.Text = step;
this.Title = "Step " + step;
}
}
protected void SM_Navigating(object sender, HistoryEventArgs e)
{
string state = e.State["historyPoint"];
if (!string.IsNullOrEmpty(state))
{
DoTheAjaxWork(e.State["historyPoint"]);
}
}
</script>
Thanks & Regards,
