Hello,

in my webproject I have integrated a reporting feature.

Please see the attached file!

Now I want to replace the listview with a dropdownmenu.

How can I do this?

I have not found a possibility to configure it.

In this example I have only two items, but in other cases there are more then two.

By the way: How can I rename the Preview-Button?

 

 

 

 

 

 

Hi

We've just updated our project for using Telerik Reporting 2019R1.

The update looks amazing! 

Our project is configured for dotnetcore-2.2 target framework and works prefect on Windows.

But unfortunately it crashes when I'm trying to open a page with Report Viewer.

I see the message: Cannot access the Reporting REST service. (serviceUrl = '/api/reports/'). Make sure the service address is correct and enable CORS if needed. (https://enable-cors.org)

Here is the log output:

Hello,

I'm Making  grouped report with crosstab according to the following layout:

 

ParentUnit

  SonUnit

ParentOption

  SonOption

SUM(data

ParentUnit2
  SonUnit
ParentOption
  SonOption
SUM(data)

 

The datasource i am using is flat ({parentunit, sonunit, parentoption, sonoption, sum(data)})

Report generation takes too much time 

can you give advice how report can be optimized.

thanks

Hi

I have very large report which has over 60k controls, so it becomes almost impossible for me to handle. The main problem occurs when designing page loaded. It shows OutOfMemory Error. Please help me divide report into multiple parts so that i can manage them easily.

 

Thanks in advance.

Hello,

I am missing the datatype double in dropdownlist of the property "Type".

I become errors in my sourcecode when I try to convert from float to double.

So, I need that datatype.

It is possible to expand the dropdownlist with the datatype double?

Why is double be ommitted? I think it is important.

 

 

Hello

I'm using Telerik.Reporting (Q3 2012 build 6.2.12.1123) for a MVC2 C# project.

Is it possible to use Radiobuttons instead of Checkboxes in a ReportView? Are there any examples?
I've got a boolean value which I want to show as a Radiobutton (True/False).

I have a report with a Crosstab on it. In Group Explorer, there is a single Parent Row group with one child (the details).  

My issue is that I can't seem to control the size of the Group Footer row - Can Grow is set to false (for the row and all text boxes within), yet it always matches the size of the detail section which can be huge. 

We have a report generated using Telerik Standalone designer where we use CSV data sources. Sometimes these data sources contain Asian characters. Our default font is "Segoe UI" which does not support these characters when generating the PDF file. Is there a way that we can define a secondary font when generating a PDF file so when a PDF is generated it will identify these characters are not available in the primary font and switch to the secondary font? 

Thank you. 

Hello,
I'm creating a report using something similar to the following classes:

 

Basically, the main report will bind to 'ManyMultipleSeries'. This class will have a list of 'MultipleSeries', which are bound to a sub report that contains the chart. The 'MultipleSeries' class could contain any number of 'Series' that need to be displayed in the chart. I could not find any way of creating a dynamic number of series like this in the docs. Thanks for any help.

Hello,

I have the following problem: I have Telerik Report Q2 2010 class with SqlDataSource set on stored procedure. This procedure has several output parameters which are (obviously) evaluated during procedure's execution. Also, this procedure returns some columns from database. Now what I want is to retrieve these parameters value after execution of procedure and use them in designer (something like "{Fields.ReturnedValue}" in for example textbox).

What is the simpliest way to do this? Some examples would be helpful.

Best regards
Rafael
