Hello,

We are using Telerik.Reporting in one of our products. I've checked that Telerik.Reporting.dll uses SQLite internally.

May I ask what version of SQLite is being used on Telerik version 10.0.16.113?

Looking forward to your prompt response.

Thanks,

Mark

I am looking for a safe way to determine if a Telerik report file was modified by us or replaced by a custom version our client made.
I was hoping to simply apply a code-signing certificate to the report file, but that does not appear to work.

The idea is that if someone were to modify the file, it would strip out our protection which we could then detect.

We do not want to prevent end users from modifying the report file to create their own report, but they would need to set it up as a custom report in our system.
This means that a simple password on the file would not work as the end user would need to know it to modify the report file and therefore could pretend that their modified version is ours.

I wish to eliminate the possibility of tech support calls due to issues with their customized file that we mistakenly believe is ours.

I look forward to hearing from you.

Hi Team,

greetings from our end. the tool is performing absolutely awesome. but we got stuck up with critical requirement. before this let me tell you, we are strictly following the following url in our implementation.
http://www.telerik.com/help/reporting/graphhowtocreateprogrammaticallygraph.html


the requirement says:
we need to set standard colors (black, white, green, red, orange, gray, .. ) for each bar we have under one and only 1 series and the color for each bar is to be defined based on dynamically mapped ProductCategoryGroup field ProductCategory from the above url.

for eg:-
product category is Bikes we need to have orange. 
product category is automobiles we need to have grey.

Now, the data source is not always loaded with same product categories list. we make load bikes, automobiles, etc:- or bikes alone or automobiles or different combination list.

I've just moved back over to using the report viewer for HTML5 in order to use the interactive feature and have a Document map for my reports.  I have received push back from my QA people that we are going to lose our infinite scrolling feature.  When doing research I came across this article:​ http://www.telerik.com/forums/infinite-scroll

which suggests that by now the HTML5 ReportViewer should have infinite/continuous scrolling.  I have not been able to find this setting, and would like some help in locating it please.

For reference if needed, I am using the jQuery.fn.telerik method to spin up a report viewer on div creation like so.

$('mydiv''))
.telerik_ReportViewer({
serviceUrl: "/../api/reports/",
templateUrl: '/.../ReportViewerTemplate.html',
reportSource: { report: parameters },
viewMode: telerikReportViewer.ViewModes.INTERACTIVE,
scaleMode: telerikReportViewer.ScaleModes.SPECIFIC,
scale: 1.0
});

,

We have a few reports implemented to work with old ASP.NET Web Forms. Recently we moved to Angular 5 + Asp.Net Web API.
The distinctive feature of those report is the dynamic design based on the data evaluated as a DataSource for that report. 

The OLD (web forms) implementation follows steps below:
We have several business entities. As a first step we get the data related to those entities:

After that we create an Instance Report Source:

GetInstanceReportSource(..) method implementation detail.
Create a report book:

For each of entities based on data obtained we create specific report instance and transfer the data into it and than attach the report to a report work book:

Return newly created Instance Report Source:

 

Finally we assign the report source to a report viewer control

New back-end (Restful Service) implementation via CustomResolver is the following:

Everything works smoothly but as per Angular Telerik Report Viewer client lifecycle there are several calls to a back-end service:
GetParameters, CreateInstance, GetDocument ... and each of them internally invokes CustomResolver.Resolve(...) which causes data for the report evaluated several times.

So my question is there is a standard sensibility point or a simple workaround on how to set up DataSource for the report viewer once or at lease during some specific stage?

I noticed that the Export functionality is not working in Angular Report Viewer at all for all reports. I got the below exception in the browser If I click on any export button.

I have a working Silverlight web app using telerik reports. I moved it to a new server and now I get the error below.  The production web site runs on the same box as the sql server that is providing the data. At first I thought it was the connection string because there was an error in it, but I corrected that and can run the report from the dev machine using that connection string. I have ensured that the deployed application is in sync with the dev box – all files are identical.

I put logging code in the data class  for the objectdatasource that the report engine uses to retrieve data from the database and that code is never run, so it looks like the error is happening on the server somewhere after the ReportService.svc and before the telerik reports use the objectdatasource to retrieve records.

An identical deploy (with a different connection string) to a different server last week works just fine. I would think there is a file missing or an old version somewhere causing the problem but the only critical files outside of telerik are the Silverlight xap file which sets the .Report property of the ReportViewer and the DLL with the report designers and data class, and both of these files are correct and up to date, and both work from the dev box using the same connection string that points to a remote sql server.  I can preview the report from the dev box and run the application and view the reports.

So can you tell me what this error means? What is NotFound? The db server? The designer class?

To me it looks like a connection string error message – it could not find the db server, but that is very unlikely.  Is there a way to trace this out on the server?

Hi all,

I'm new to Telerik Reporting so forgive me for my ignorance. I read this article about using SQL parameters in a report: 

https://docs.telerik.com/reporting/sql-data-source-using-parameters

But I can't get it to work and I'm wondering what I'm doing wrong. I have a simple query that looks something like this:

And I set the Parameter in the database connection Name: @OrderDate; Db Type: Date; Value: = Parameters.Order_Date.Value

In the report, I created one ReportParameter, and I called it "Order_Date". It is set to AutoRefresh: True; Type: DateTime; Value: 1/6/2019; Visible: True.

When I try to execute the query from within the SQL box where I enter the parameter information, it works. But when I try to Preview the report, the wheel just turns forever and nothing ever displays and I get no error. Can someone help me figure out what I'm doing wrong? 

In my report, I use cross table to show my data. I set keep together to false in order to show the data to the bottom of the page. but there is no bottom line of text box (see attachment 2.png). I want to show the data like 1.png. now I add a text box in page footer, but this report is a sub report in a big report. I can not use this method to show the bottom line. how can I get it.

 

 

Hello,
I have successfully created a report in my application and I want to save it to my disk but before saving it I should be sure that the data in the report is fully loaded from the Database. The problem is that the database isn't in the local computer and I am connecting to it remotely through the internet and it takes some time to retrieve the data depending on the internet speed which is low in my country so I have to "Thread.Sleep" my application for a few seconds in order to fully load the report and the problem is i don't know how much time i need to load it so I was thinking of a way which I could check if the report is fully loaded instead of using the Sleep function. does the Telerik reporting have such a function which i could use to check the report is loaded and after that saving the report to my disk?
Thank you
