[How Do I:] Use the ASP.NET AJAX History Control?

One problem faced by a typical AJAX application is that a partial page update is not added to the history of the Web browser. This means that the browser's Back button does not move back one AJAX step, but moves back one entire document, which is unlikely to be what the user expects. The ASP.NET AJAX History control allows the developer to insert history points so that the user may click the browser's Back and Forward buttons to move between AJAX steps.

I am sorry, but every time I watch your video, I need go to have a cup of coffee first. Your voice makes me sleep.

Good subject though.

The Dim startPage As Int32 = 1, should change to: Int32 = 0.

Otherwise, the "Back" button can't bring you to the first page.

Protected Sub History1_Navigate(ByVal sender As Object, ByVal args As Microsoft.Web.Preview.UI.Controls.HistoryEventArgs) Handles History1.Navigate

Dim startPage As Int32 = 0 ' change 0 to 1, (James)

If args.State.ContainsKey("StartPage") Then

startPage = CInt(args.State("StartPage"))

End If

GridView1.PageIndex = startPage

End Sub

Haw to get the History server control into my AJAX-style application if it’s not appear in tool box?

I find that ‘an inherent problem with AJAX-style applications is browser navigation. Because an AJAX-style page can interact with the server by using asynchronous postbacks, users can perform many tasks without leaving the page. However, if users click the browser's Back button, by default the browser does not return to a previous state of the page (for example, the state before the most recent asynchronous postback). Instead, the browser unloads the page entirely and returns to the page that was displayed before your page was started. Very frequently, this is not what the user intended.

You can manage history (Back and Forward button navigation) to provide a more logical and natural navigation model in your Web application. As the page developer, you control the state that is required to recreate the page. You can manage history navigation in both server and client code.’

But what to do if the History server control is not appear in tool box?

Thank you for help

I'm running Visual Studio 2008 with .NET 3.5 SP1 and the AjaxControlToolkit version 3.0.30512.17815, but I don't seem to have this History Control in my toolbox.

Does anyone know where can I find it?
