Hi!

I'm not sure if this is the right place to post this. I'm trying to figure out how to implement custom user functions for use with the reporting server. I was successfully able to implement custom aggregate functions as per this documentation: https://docs.telerik.com/reporting/expressions-user-aggregate-functions

However, when attempting to implement custom functions using this documentation, I cannot get it to work: https://docs.telerik.com/reporting/expressions-user-functions

The functions implemented in this way show up for use in the standalone report designer, but when using them they return an error: "function not defined in current scope"

Am I missing something obvious? Any help would be appreciated! 

Thanks

     

Hello,

I am currently working on a project that requires me to generate a report then turn it into a pdf and send it in a email. I currently understand how to generate a report for a report viewer using uriReportSource, but I don't understand how to generate the report in the code behind then turn it into a pdf.

How to localize Rich Text Editor component displayed by the Send Mail Message Dialog in the HTML5 Telerik Report Viewer?

 

 

HI,

I want to share my experience with binding an IEnumerable<String> to a report.

Normally, you bind a collection of complex objects with public properties:

Then, in a report's textbox, you specify this expression to load the data from MyType object:



But what if you want to just bind a list of strings without creating redundant wrapper types?

You can't just set "= Fields" expression to a textbox, it will produce "Incorrect use of Fields" exception. But you can set following expression and it will work (RawData is of type Object, so I guess it calls ToString() method internally):

Hi all,

We are using Report Web Designer. We have implemented custom storage (IDefinitionStorage). We have implemented SaveDefinition method where it saves the edited report in a custom way.

There can be some validations and save can fail. For this I am just throwing a new Exception.  

The question is, which kind of exceptions needs to be thrown so that the message of exception shows in a report designer?

In an attachment you can see that the error message is showing in a general way, and it doesn't show my custom message.

 

Thanks,

Hello,

I'm trying to test Telerik Report with .NET Core 3.1 and object data source.

The report is working correctly when running from Visual Studio but when I publish and put it in IIS, I see the below error in every binding.
"An error has occurred while processing TextBox 'textBox15': The expression contains object 'OpeningBalanceDate' that is not defined in the current context"

I'm using the report designer and the assemblies that has the object datasource are netstandard2.0

What could be the issue?

I have Rest Service (ASP.Net Web Application-->Empty-->check MVC)

Result: successed (pictrure: 1.jpg)

I have project Angular and call Rest Service

<tr-viewer [containerStyle]="viewerContainerStyle"
[serviceUrl]="'http://localhost:56342/api/reports'"
[viewMode]="'INTERACTIVE'"
[scaleMode]="'SPECIFIC'"
[scale]="1.0">
</tr-viewer>

Error (picture: 2.jpg)

Error loading the report viewer's templates. 

 

I have a table that has a column that may or not be visible. When it isn't visible I then need to adjust the proceeding 2 columns, one to put in the now invisible column's space and the second to increase its width. I have been able to get the column to be invisible via formatting but am not sure how to move and adjust the other columns. I had the same issue with rows and had to create a table for each row and keep track of the visibility and location of each row myself.

We have 2020 R2. I'm trying to implement a ReportSource class but when I try to implement the required Clone method VS 2019 gives me the error "no suitable method found to override". What's going on?

Hi,

I want to generate a pdf report expected to have 8000 pages. As of now I am experiencing Memory Out of Exception. Is it possible to generate the report in batch mode. For example, generate 1000 pages first then the next batches

or 

Is there any other ways to over come this memory out of exception issue.

 

 

Thanks
