Hello ,

I am using telerik report designer R3 2016, and when I m drawing line chart using line chart, consider i have a data for the days 1,2,4 and 7 in the x-axis and 0 -100 in y axis . The line chart draws perfectly on the nodes 1 to 2, 2 to 4 and 4 to 7. But the the problem is here in x- axis 3, 5 and 6 is missing (obviously the node not drawn there) . is that any way to show the line chart 1 to 2, 2 to 3 ( go default to zero even no value is mention to draw), 3 to 4, 4 to 5, 5 to 6, 6 to 7.  Exactly to say the missing values which is not given from the user it should go down to zero and draw the nodes which the actual data. please see the screen shot for further reference.

When no value it should not directly pass to next node, My idea to show the amount of sales in particular day/month, the missing days/month not having any data means no sales. should go down to zero. If I process from back-end its huge amount of data generate for zeros.

Using C# code, we can set the missing value property as zero, but in designer i am not able to find this property, please can anyone help me to come out of this.

Hello,

I just installed Telerik Reporting r1 2019.

It tells me that the installation was successful, but Visual extudio does not detect the extension.

How could I add it?

Thank you.

Hello,

i have problems to resolve ExpensesData[] (Indexer,Array or what ever) in my table column.

Please see the attached file.

In the column "Fahrtzeit" I become the message --> ReportLibraryTest.DriverReportService.ExpensesData[]

What can I do to get to the data.

Is there an easy way to resolve contents of lists or arrays into table columns?

Thats the implementation of ExpensesData[] in the Webservice:

  [System.Runtime.Serialization.DataMemberAttribute()]
        public ReportLibraryTest.DriverReportService.ExpensesData[] Expenses {
            get {
                return this.ExpensesField;
            }
            set {
                if ((object.ReferenceEquals(this.ExpensesField, value) != true)) {
                    this.ExpensesField = value;
                    this.RaisePropertyChanged("Expenses");
                }
            }
        }

thanks in advance.

Hi,

I have crated class library report (.cs) and wanted to know how to set some value to textbox using ReportsController (i.e. web api)

Thank you!

I am trying to set up the report viewer to display a report using the InstanceReportSource. I want to use the InstanceReportSource because our application programmatically renders, compresses and downloads mass reports. I have followed this guide and have set up the rest service and custom resolver. I am using the same code to create the reports for rendering/downloading and for passing to the report viewer. The rendering and downloading works just fine but the report viewer is blank. During debugging, I can see the Reports API controller being hit and the resolver creating the InstanceReportSource.

I have created a a sample application that shows how I am using the reporting service. I'm sure that I'm missing something minor. I just can't figure out what. Any help would be much appreciated.

Sample Application Download

I have a Telerik Reporting Library 2019 project which contains Telerik Reports. The reports are consumed from a ASP.NET Core web application when controller actions are called. So there is a reference to this Reporting library project from Web project.

In the web project I create a ReportBook to generate report. and render the report as a PDF.

 In the reports I have few PictureBox components. I want to set pictures from a http url (https://docs.telerik.com/reporting/report-items-picture-box#data-binding)

Example

But when I try to do that it always gives an error (report-error.png). Is this because I have report definition in one project and consuming it from another project (web project). How can I solve this.

Hi. I have error page. (attached file)

We have four servers. only 1 server has this problem. All settings are same. I couldn't find any differences.

The report page has just a small circle shape.

I used default Html5ReportViewer1.html and aspx form which is created by Visual Studio new file menu.

When I use fiddler I got this message with URL /api/reports/clients.
