Not sending RadEditor's content to server.

We have a page with RadEditor on a tab strip. There are scenarios when RadEditor contains a lot of html and when doing a post back in order to switch the tab, all its contents is being post back to the server. This results in gigantic performance loss (there are times when post backs are sending tens of MiB of data).
Is it possible to tweak RadEditor in such a way that it does not send its contents over to server on postbacks? Our code-behind does not rely on RadEditors Content property accessor (does not read its content explicitly), only its mutator (its contents are set from within the control's code-behind).
Is it even possible to do such things with any of Telerik controls and if it is, then how do we achieve such result?

It's worth pointing out that we use relatively old Telerik version (2013.2.611.35) and we can't switch to a newer version at the moment.

Thank you in advance.

Trying to solve a issue with a long running report adn letting the user know to wait

So I posted a question on the ASP.NET forums @ Microsoft and I have not gotten any useful suggestions on how to solve this issue. I am hoping perhaps a telerik tool might be able to solve this issue...

If you know of something please point me in the right direction...
here is the original post.. I have copied it below...

QUICK COMMENT:So I am currently trying to figure out how to use AJAX, JQUERY, BLOCKUI and ASHX handlers to generate a very large report in CSV. The report generation is spawned by clicking on a hyperlink which will call a javascript function that will execute a AJAX call. As of right now I get the ajax call to execute, but I have not yet figured out how to get the ajax success method to dump the report to the calling client browser yet.

How do I get the ashx handler to work with the master page to generate a report when the user clicks on the hyperlink.I can get it to work if I just route the hyper link control directly to the ashx page, but I eventually need to add code to block the UI while this report being generated. In the ajax, I am thinking I need to do some type of action to force the browser to kick out the report.. Just not sure what...I have a master page with the following code:

<script type="text/javascript">

function startReport(result) {

$.ajax({

url: "HTTPHandlers/TagExportHandler.ashx",

context: document.body,

success: function(){

alert("done");

//Eventually put code to block UI and etc while report is rendering...

}

});

}

</script>

In the markup I have a asp:hyperlink control... <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/HTTPHandlers/TagExportHandler.ashx" OnClick="startReport('');">Tag Export 2</asp:HyperLink>

Then I have a ASHX control that does the following..

public void ProcessRequest(HttpContext context)

{

using (var db = new TIPWebITDataContext())

{

string _exportContent = "";

int[] userDepartments = ((User)HttpContext.Current.Session["currentUser"]).Departments.ToArray();

List<TagDetailsDepartments> tagsModelCsvDepartmentses = null;

List<TagDetailsNonDepartments> tagModelCsvNonDepartmentses = null;

var data = GetTagDetails(db, "");

CsvContext cc = new CsvContext();

using (var writer = new System.IO.StreamWriter(context.Response.OutputStream))

{

CsvFileDescription output = new CsvFileDescription

{

QuoteAllFields = true,

EnforceCsvColumnAttribute = true

};

context.Response.AddHeader("content-disposition", "attachment; filename=TagExport.csv");

context.Response.ContentType = "text/csv";

if (userDepartments.Count() > 1)

{

tagsModelCsvDepartmentses = ((IQueryable<TagDetailsDepartments>)data).ToList();

cc.Write(tagsModelCsvDepartmentses.ToList(), writer, output);

}

else

{

tagModelCsvNonDepartmentses = ((IQueryable<TagDetailsNonDepartments>)data).ToList();

cc.Write(tagModelCsvNonDepartmentses.ToList(), writer, output);

}

context.Response.StatusCode = 200;

cc = null;

writer.Flush();

output = null;

}

data = null;

tagsModelCsvDepartmentses = null;

tagModelCsvNonDepartmentses = null;

userDepartments = null;

// context.Session.Add("TagExport", "Complete");

GC.Collect();

GC.WaitForPendingFinalizers();

}

German umlauts

Hello,

I have a little problem with the RadBarcode QR-Code. I have build an webapplication (asp.net c#) to generate buisness cards and on the back of the buisness card is an vcard QR Code image. This works fine and i can scan the code with my Windows, Apple and Android device. My problem is just, that the german umlauts (üöä) isnt in the generated QR Code. I've been experimenting with the settings.
My best result is with ECIMode = ISO8859_1En, Apple and Android works but the Windows device don´t work.
With no ECIMode the german umlauts dont show on any device.

Is there any solutions or workarounds that i can do?

thanks

Load On Demand, WebService Parameters

In the load on demand example, you are calling a web service with a method GetRotatorData. the signature of GetRotatorData requires a parameter called itemindex. I cannot see where you are setting this in the rotator defintiion or the javascript of the page.

Can someone point me in the right direction. We have a web service which requires us to pass in a date of the last post displayed on the page, we'd like RadRotator to get the data from the web service and then when it needs more data (load on demand) it send the max date back to the web service.

Can you provide any guidance?

Upgrade Wizard Failing

Running VS2012 Ultimate and I am trying to use the Telerik Upgrade Wizard on my web project.
I am trying to upgrade to version Telerik.Web.Ui v.2014.3.1209.40 from v.2012.2.815.35

After clicking through, I get the error:

The wizard encountered an error while trying to handle user event.System.ArgumentException: The path is not of a legal form.
   at System.IO.Path.NormalizePath(String path, Boolean fullCheck, Int32 maxPathLength, Boolean expandShortPaths)

   at Telerik.WizardEngine.Helpers.EventHelper.<>c__DisplayClass1.<RaiseEvent>b__0()
   at Telerik.WizardEngine.Helpers.EventHelper.CatchExceptionAndSendReport(Action action)

and the Wizard fails. I have no other problems with upgrading. The project path is reasonable, has no funny characters in the folder name.

Any ideas? How would I go about upgrading the project manually if required?

Thanks,
Bryan
