Report is unavailable or session has expired.

Hello:
Any help is appreciated with this error.

I do not get this error when I run the report on my local machine, but only when I deploy it to a different server (Win 2K8 R2).

I researched on the web and found that there is no support yet for MVC 3, but I was wondering whether anyone out there had the issue and found a solution.

Please let me know any specific information regarding the application that will help you answer.

Here is the code for my view:
==

<%

@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<BVReport>" %>

<%

@ Register Assembly="Telerik.ReportViewer.WebForms, Version=5.0.11.510, Culture=neutral, PublicKeyToken=a9d7983dfcc261be"

Namespace="Telerik.ReportViewer.WebForms" TagPrefix="telerik" %>

<

script runat="server">

protected override void OnPreRender(EventArgs e)

{

rvReport.Report = ViewData.Model;

base.OnPreRender(e);

}

</

script>

<!

DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<

html>

<title>BVReport</title>

html#html, body#body, form#form1, div#content, center#center

{

border: 0px solid black;

padding: 0px;

margin: 0px;

height: 100%;

}

</

style>

</head>

<body>

<telerik:ReportViewer Width="100%" Height="100%" ID="rvReport" runat="server" />

</form>

</body>

</html>

Q2 2011 broke IHttpHandler cast

We have a ReportViewerExtension that casts an instance of Telerik.ReportViewer.WebForms.HttpHandler as IHttpHandler. This has worked for years, but no longer runs after installing Q2 2011, throwing a run-time error that "Unable to cast object of type 'Telerik.ReportViewer.WebForms.HttpHandler' to type 'System.Web.IHttpHandler'."
Any ideas what happened (and how to resolve)?
Best,
Scott

Export to RTF with HTML in the body

Hi Guys

We are using the reporting module to produce a printable document out of our database system. Some of the input fields that form the record we are reporting on use the RadEditor to allow our users to be more descriptive with their input.

The problem we are seeing at the moment is, when we export the report to RTF, the actual html which is input in the report is being shown in the exported document.

Everything works OK when viewing in the report viewer.

Any thoughts?

Shane

sqldatasource stored procedure no results

Hi,
when i try and run a complex stored procedure using sqldatasource:

this.sqlDataSource1.SelectCommandType = Telerik.Reporting.SqlDataSourceCommandType.StoredProcedure ;

this.sqlDataSource1.SelectCommand = "myProc";
crosstab1.DataSource = sqlDataSource1;

it does NOT return any results.

if i use text: this.sqlDataSource1.SelectCommandType = Telerik.Reporting.SqlDataSourceCommandType.Text ;
this.sqlDataSource1.SelectCommand = "EXEC myProc";
crosstab1.DataSource = sqlDataSource1;

This used to work until i had to upgrade to: 4.2.10.1221

What do i need to do,
i need to execute as StoredProc as i pass in parameters.etc.

I've verified if i made a simple proc, and do:

this.sqlDataSource1.SelectCommandType = Telerik.Reporting.SqlDataSourceCommandType.StoredProcedure ;

this.sqlDataSource1.SelectCommand = "mySimpleProc";
crosstab1.DataSource = sqlDataSource1;

it also works.

The complex proc has temp tables, and calclations,etc...

Also when using the crosstabwizard or reporting wizard, the columns comeback but executing the the proc "myProc" also does NOT give results in preview.

Report background

I want to apply a watermark type image on the report but want to change it dependant on the state of the document content i.e. if i had a Perameter that returned a string of "Draft" i would want to apply the Draft image to the whole report likewise if the function returned "Approved" i would want to apply the Approved image instead?

LINQ in an object data source

I'm very new to telerik reporting, I'm sure I'm missing something;

I have a simple report that has a text box
I have the following classes in the report.cs

class DealerDataSource

{

public IEnumerable<CalDealer> GetDealerInfo()

{

DAdbDataContext xxx = new DAdbDataContext();

// Dealer deal = db.Dealers.First(d => d.DealerId == 2);

CalDealer cd = new CalDealer();

cd.Title = "Test";

yield return cd;

}

public class CalDealer

{

public string Title { get; set; }

}

When I add the data context and go to preview the report it gives the error of
"object reference not set to an instance of an object".
It compiles OK -

If I take out DAdbDataContext xxx = new DAdbDataContext(); the report previews fine.

I know the data context is good as I'm using it in the code behind of a page.

Thanks!!

Ron

Reporting Q2 2011 new caching feature questions

I'm trying out the new Q2 2011 version 5.1.11.713 features.
I keep reading the "Whats new" section and I'm seeing talk about these new caching features; however I am a little confused.

Does caching only work when using the WCF Reporter Service Implementation?
Can I use the caching features with the standard ASP.net web viewer control?
Will caching work in an out of proc session state set up?

I've been searching through documentation and i can't seem to find hardly any on these subject.

My reports are larger reports and are throwing out of memory exceptions when running in out of proc session (web farm).
I've read numerous forum post on these issue and have read the design considerations.
Just wanted to look into the caching options to maybe reduce these errors, but i can't find any documentation or guide on the caching topics.
I would like some more information if anyone could help.
Any information regarding caching or memory exceptions would be great.

How to set the value of the X axis Label

Hi

I have a very simple question : Is it possible to change the value of the label on the X Axis. In fact, what I want is to replace the number under the bar (bar chart) by a date (Look the attached file to see what I mean)? For me, it seem that it should be possible and really easy to do, but I look in the doc and it seem that only number can be set to the X axis label. So, is it right or is it a way to do what I want ?

Thank you,
David
