Hi,
I have a big problem.
My current page have no master page, but my project have master page.
I am loading 3 usercontrols dynamically using webmethod and jquery.

code like this

[WebMethod(EnableSession = true)]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static string GetReviews()
        {
            string content;
            using (Page page = new Page())
            {
                UserControl userControl = (UserControl)page.LoadControl("GetReviewsData.ascx");
                page.Controls.Add(userControl);
                StringWriter sw = new StringWriter();
                HttpContext.Current.Server.Execute(page, sw, true);
                content = sw.ToString();

            }
            return content;
        }

Page is loaded perfectlly. But I have two textboxes and button in a page. When I entered something on textboxes and click button I got error like this.

The job of a webserivce is not to controls to a page. please find another way for it

NagaRaju Pesarlanka 17-Jul-14 1:49am

I think webmethod is not a problem.

Thomas Nielsen - getCore 17-Jul-14 6:08am

looks like you're using webmethods for partial postbacks and i guess some of the modified stuff belongs to the full postback and .net deems it out so to say.
consider not using viewstate at all and simply turn it off if avail

NagaRaju Pesarlanka 17-Jul-14 6:11am

Thank you for reply me...
I will check it

NagaRaju Pesarlanka 17-Jul-14 6:39am

I disable and enable in pageload, not working.

Thomas Nielsen - getCore 17-Jul-14 6:50am

use the page directive on top of the aspx file or even in web.config EnableViewState=false, then it cannot fail because it is not beign used and you should of cause verify that you are not using ViewState["yourvariable"] like structures anywhere or they'll stop working :)

I understood from your comments that turning ViewState off can work for you, please refer to this on how to do that:
http://msdn.microsoft.com/en-us/library/ms972976.aspx[^]

specifically:
http://msdn.microsoft.com/en-us/library/ms972976.aspx#viewstate_topic9[^]

If not in use ViewState cannot be corrupt of fail and anyway it is a very slow way to persist data between calls as it increases the data going to and from and affects page load times greatly

not a problem, no code in my pageload, I am using jquery.

Thomas Nielsen - getCore 18-Jul-14 3:52am

ment in the browser :) ViewState as you propably know sends data to and from the browser instead of keeping it at the server and hence the document load in the browser increases when it is in use and it is not a godsent in relation with partial postbacks, such as webmethods

NagaRaju Pesarlanka 18-Jul-14 3:55am

Is there any alternate without webmethods.

Thomas Nielsen - getCore 18-Jul-14 4:31am

You could use a webservice, but the essential here is getting rid of the contens of ViewState here, like what you've posted, and in that relation it doesn't matter which way you're getting data

NagaRaju Pesarlanka 19-Jul-14 0:44am

I want to load usercontols using webservice, Is it better way or not? I got any above viewstate error? Please suggest me, I will try this way.

Thomas Nielsen - getCore 22-Jul-14 3:35am

Yes isn't that what you're posting?
"Exception Details: System.Web.HttpException: The state information is invalid for this page and might be corrupted."

NagaRaju Pesarlanka 22-Jul-14 3:37am

yes

Thomas Nielsen - getCore 22-Jul-14 7:49am

and that is Your ViewState, you could be facing something like http://social.msdn.microsoft.com/Forums/vstudio/en-US/25f2886c-b560-434e-8dab-44a8adf4d34a/the-state-information-is-invalid-for-this-page-and-might-be-corrupted?forum=netfxbcl

NagaRaju Pesarlanka 22-Jul-14 7:53am

I got the soluation. Just override the viewstate and save it as session.
protected override object LoadPageStateFromPersistenceMedium()
{
return Session["_ViewState"];
}
protected override void SavePageStateToPersistenceMedium(object viewState)
{
Session["_ViewState"] = viewState;
}
</script>
<form runat="server">
<input type=hidden name=__VIEWSTATE>
</form>

Thomas Nielsen - getCore 22-Jul-14 8:02am

Pleased to know :)

NagaRaju Pesarlanka 22-Jul-14 8:07am

yah, This is working, I was searched so many sites but only msdn site gave the answere.

Thomas Nielsen - getCore 22-Jul-14 8:17am

What that your problem was the viewstate? I new you would find it with the MSDN links i posted. and i believe it is now 4 days since i mentioned that you should do what you wrote 20 mins ago that you did ;)

NagaRaju Pesarlanka 22-Jul-14 8:19am

The link is

Thomas Nielsen - getCore 22-Jul-14 9:11am

That is a very informative link and it may help somebody some day understanding why indeed. The essentials ofyour solution is, that you move data from ViewState to SessionState which is to say away from ViewState when you're not making full postback which was what i suggested, but without code examples it was difficult to show you how and as you'll see on these comments and the direction from the solution it was all about loosing your variables in viewstate, which utlimately you did. Although the naming is somewhat unfortunate as it a session variable named viewstate may be confusing to the next guy maintaining your code :)

unless you're writing back to the .net input named __ViewState in which case .. well that's somewhat unecessary

NagaRaju Pesarlanka 22-Jul-14 9:21am

I was taken only session variable on my home page. In my page have no viewstate variables. This page is included in a project but this is deffers from entire project, because it is a single page, I mean no master page. It will not linkups to other pages. Ultimately I think sessionstate is not a problem in present scenario. Anyway I am very thanks to you for your valuable suggestion.

Thomas Nielsen - getCore 22-Jul-14 9:40am

glad i could help

NagaRaju Pesarlanka 18-Jul-14 5:57am

ok. thank you for suggest me, I will try...
