Using a Silverlight application and Telerik ReportViewer we're having the following issue.

We have a drop down to pick a client. That is passed to the report SQL and is all working fine.

If I run a smaller client report (up to about 60 pages or so works fine), it comes back fine.

If I run a larger client report... I get the following message.

Error: System.Reflection.TargetInvocationException : An exception occurred during the operation, making the result invalid.  Check InnerException for exception details.

at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary()

at Telerik.Reporting.Service.SilverlightClient.RenderAndCacheEventArgs.get_RenderingResult()

at System.Net.Browser.AsyncHelper.<>c__DisplayClass4.<BeginOnUI>b__1(Object sendState)

Same report... only difference is the volume of data. I can subsequently pick a smaller client and it reloads and renders just fine.

This error occurs (by me counting) about 40 seconds after the initial call.

I have tried setting the binding as follows (and confirmed the code gets called)

public ReportServiceClient Create(Uri remoteAddress)

{

var binding = new BasicHttpBinding() // or BasicHttpBinding(BasicHttpSecurityMode.Transport) overload if SSL is used

{

MaxBufferSize = int.MaxValue,

MaxReceivedMessageSize = int.MaxValue,

ReceiveTimeout = new TimeSpan(0, 15, 0),

SendTimeout = new TimeSpan(0, 15, 0),

OpenTimeout = new TimeSpan(0, 15, 0)

};

var endpointAddress = new EndpointAddress(remoteAddress);

return new ReportServiceClient(binding, endpointAddress);

}

The report is configured using a SqlDataSource object and the CommandTimeout there is set to 900 seconds. After that SQL text is used with a single parameter.

Again it only fails on large amounts of data... It works fine in Preview mode (design time) as well. One big one is 1400+ pages which is only about 42,000 rows.

Hi Kevin,

We have not encountered such an issue so far and do not believe this could be a browser specific problem. Please disable any firewalls or antivirus programs you have locally and if this does not make a difference try accessing your site from another location just to be sure this ain't related.
If the problem persists, use web debugging proxy like Fiddler to see what is the response from the server and whether there is a more user friendly error returned. You can also review the IIS and server logs to see if there isn't anything that could hint what is happening.

Greetings,
Steve
the Telerik team

Q2’11 SP1 of Telerik Reporting is available for download (see what's new). Get it today.

"We have not encountered such an issue so far and do not believe this could be a browser specific problem."

I give you information and then have to wait 2 days to be have that information dismissed out of hand and told essentially to "make sure the computer is turned on".

One step ahead of you...

Have been using Fiddler in all this.
Have tried on different machines.
Have been working with our infrastructure team to insure it's not a firewall timeout.

The ONLY variable, as I reported and you ignored... is the browser.

Machine1 (client) using Firefox (browser) hitting Machine2 (server) - FAIL
Machine1 (client) using Chrome (browser) hitting Machine2 (server) - FAIL
Machine1 (client) using IE (browser) hitting Machine2 (server) - SUCCESS!

Machine1 (client) using Firefox (browser) hitting Machine1 (server) - FAIL
Machine1 (client) using Chrome (browser) hitting Machine1 (server) - FAIL
Machine1 (client) using IE (browser) hitting Machine1 (server) - SUCCESS!

Machine2 (client) using Firefox (browser) hitting Machine2 (server) - FAIL
Machine2 (client) using Chrome (browser) hitting Machine2 (server) - FAIL
Machine2 (client) using IE (browser) hitting Machine2 (server) - SUCCESS!

Machine3 (client) using Firefox (browser) hitting Machine2 (server) - FAIL
Machine3 (client) using Chrome (browser) hitting Machine2 (server) - FAIL
Machine3 (client) using IE (browser) hitting Machine2 (server) - SUCCESS!

The ONLY VARIABLE IN the SUCCESS or FAIL is BROWSER

Fiddler reports nothing on the failures... the calls just fail.

Please do not ignore this and please try to offer some helpful suggestions of what to check. If you don't believe my competency in this, I can make a video demonstrating that this is BROWSER RELATED.

UPDATE:

From Fiddler... here are the calls that the Telerik Reporting engine is making... You will see they are the same except for the browser (and the Silverlight URL ID -- cannot do anything about that)

Also of note... with Firefox, the report times out -- but watching Fiddler, the response actually DOES come back with all the data. It's 100% identical to the response with IE. Somehow the Report control under Firefox is timing out.
