Telerik Q3 2014
Visual Studio Ultimate 2013
MVC 5 Report Viewer

Report works locally fine, deploy to IIS 7.5 and get below error.
Internal Server Error
An error has occurred.
Access to th epath 'C\Windows\TEMP\ReportService\...\LastCheckTime
value.dat is denied.

I go to the server and delete the TEMP data then the report works again.

Why is this erorr occuring and what is the resolution. We cannot have random Telerik failures in production.

I am receiving a System.NotSupportedException of "Adding or removing items from a 'HttpRouteCollection' is not supported. Please use a key when adding and removing items." when my application hits the ReportsControllerConfiguration.RegisterRoutes() method. 

Thank you for assistance in advance.

Hi Team,

 

Good Day!

 

I am using a Standalone Telerik Report and I want to set a new ObjectDataSource from a Dataset during run-time. But even how much I tried the report cannot retrieved or used the new ObjectDataSource that I set during run-time. Below is My Code. Please kindly help assist on which part of my code do i get wrong or is this possible in Telerik Report?

Hello,

When I run a report telerik after making changes in the X-Axis Rotation Label to better fit them in the chart of type "Chart", the change isn't verified and returns to the default setting.

How is this possible? Is there any step that should follow?

I'm using 6.1.12.823 version of telerik reporting integrated with Visual Studio.

Best Regards,
Emídio Teixeira

Hi Everyone

 

ASP MVC project.
I use Q1 2015 SP1 (9.0.15.324)
I have page with Html.TelerikReporting().ReportViewer()
There are parameters which user can set. I want to crate functionality which will send email with attached pdf report from this ReportViewer.
What the best way to implement this functionality? Could I export Report on HTML page array bytes (PDF) in JavaScript ?​

Hi,

I need some help retrieving the active set report parameters from a web report viewer.

I have a aspx page with the report viewer on it, in addition to the viewer I also have a custom email button. When the user clicks on that button I would like to sent a mail with the current report as a attachment. Problem with that is that when the user changes a few report parameters I have to apply those changes to report before I create the PDF file.

The creation of the PDF file I'm doing with the report processor:

 Problem with the code above is that the parameters of the report viewer report source are the original parameters and not the ones who the user has changed.

 Anyone suggestions how I can send the displayed report as a PDF attachment in a mail?

 

I am trying to create a report that is structured like the attachment.   I have to fields Machine and Category that would be a header and then data pertaining to those 2 would be listed under.  Right now I have a sub report using a table.  I get the data from the DB and stuff into a datatable.any help is greatly appreciated. 

I am creating a Report in Hebrew, that means it is right to left.

 

I have now a Table that is in the following form

 

aa     bb   abc   x

aa     bb   def    x

aa     bb   ghi    x

cc     dd    jkl     y

cc     dd   mno  y

 

and what I would like to get is:

aa     bb   abc  x

                 def     

                 ghi     

cc     dd    jkl    y

                 mno

 

or at least:

aa     bb   abc   x
aa     bb   def    
aa     bb   ghi    
cc     dd    jkl     y
cc     dd   mno  

Is it possible with the standalone Report Designer to achieve something like that, and if yes how? Is there a way to change the groups from being added to the left side of the table, to be added to the right side?

step 2:

Error Message:"
System.Web.Razor.Parser.TokenizerBackedParser~3[TTokenizer,TSymbol,TSymbolType]"上的GenericArgumnets[0]"
System.Web.Razor.Tokenzier.CSharpTokenizer“违反了类型”
TTokenizer“的约束。

 This is a screenshot!

 Have you an Idea to solve this ? Thank you.

 

Hello All,


There are 4 parameters in my report from COO->VP-->region-->district, which designed in a cascading way.
I setup them all as "auto-refresh". In the first time, it works well.

If I choose Coo1, All for VP , all for region and all for district, once you finish choosing, the report is triggered to run. However, if after reports return, u re-choose a specific VP(VP1), the region and the district still stand as "all" and the report does not trigger to run.

Now, I wanna achieve like this, either the 2nd time I change my VP parameter, then reports can refresh or I change VP parameter then the downstream parameters can be back to "select a value" instead of standing as "ALL".

Who has any idea on this?
Thanks in advance.
