Hi,

When processing report, an error can occur. Report error can be different. For example:

• When a report has OData connection and if the OData request doesn't execute successfully (see "ErrorWhenODataRequestIsNotSuccess.PNG" attached file).
• When a report shows error while processing report item (for example, when we bind wrong parameter name to TextBox. See "Error while processing report item.PNG" attached file)
• etc.

When we print the report (or export to PDF file), it will continue printing the report which has an error in its content (see Print report with error.PNG file). The question is, how we should catch the report error before start printing? We use HTML5 report viewer to show report, we use Syncfusion package to print pdf format of our report, and also in backend side implemented our customer report resolver. We don't require printing wrong report. But, we want to do some actions before printing wrong report.

Thank you,

Hi all.

I've been using Telerik for Silverlight and WebForms.

Now I need help for a friend of mine, and i need to issue a page for each row in a table, aboout 1200 rows and each one having 9 columns. I've built a VisualStudio VB project with 2 forms, in the first one i ask for the name of the table, the 2nd one hosts ReportViewe. Can you pls help me in this issue?

I am trying to convert a clr report to a trdp report, but when I call ReportPackager.Package I get the following exception:

Test method Purolator.Reports.Test.ConvertReport.CreateReportTest threw exception: 
System.ArgumentException: Invalid name character in 'List`1'. The '`' character, hexadecimal value 0x60, cannot be included in a name.

Hello,

I'm trying to use the keep-alive feature of the Reporting services which is described here. I'm doing it to get rid of the 'expired client' message.

I couldn't find any elaborate tutorial how to achieve that.

What I'm trying to do:

• Send a POST request to https:/localhost:44325/api/reports/clients/keepAlive/87e05e1425d (which is a correct Reporing API Address with a correct client Id ). The server returns 404. 
• Inspect Telerik.Reporting.Services.AspNetCore.ReportsControllerBase method signatures in Visual Studio. It doesn't contain anything reminiscent of the keepAlive method.

Is there a complete tutorial how to set up the keep-alive?
I'm using Telerik.Reporting.Services.AspNetCore 15.0.21.224 with a standard configuration as described here:
https://docs.telerik.com/reporting/telerik-reporting-rest-service-aspnetcore-mvc-core3

I have a requirement to write a report that serves up data from our "Email Queue" table. A challenge will be that emails can have copy/pasted content from word and outlook so has random HTML tags that I know are not supported by Telerik Report. In some cases if uses paste images then these are stored as raw Base64 values in the HTML.

What options do I have available???

Even this simple example is failing...

Hello, 

I am getting this error: "Data at the root level is invalid. Line 1, position 1.'", when I try to Render the report. this is my code.

var uriReportSource = new UriReportSource();
 uriReportSource.Uri = @"D:\Projects\folderName\folderName\folderName\folderName\Reports\reportName.trdp";

var deviceInfo = new Hashtable();

ReportProcessor reportProcessor = new ReportProcessor();

RenderingResult result = reportProcessor.RenderReport("PDF", uriReportSource, deviceInfo); - here I am getting the error.

Thank you :)

Hi Guys

I want the user to be able to select which columns we display in their reports. I've got a multiselect parameter that has a list of the reports' columns as the display member (and a number as the value member).

In the Column Groups I've added in a filter on one of the columns like so:

However when I try to run the report I get this error:

I've troubleshooted the Parameters.availableColumns.Value and it has the expected values.

I've troubleshooted this expression "1 In Parameters.availableColumns.Value" in the report body itself and it works as expected (shows true/false correctly)

I've changed the expression in the Column Grouping box to both "1 = 1" and "1 =2" and it shows/hides the column as expected.

The only thing I can think of is Parameters.availableColumns.Value isn't populated when it hits that expression in the Column Grouping. Is that right? And if so how can I go about giving the user the option to select the columns they want to show?

I have a bar chart embedded into a column of a report. The report has these columns:

Name

Responses

Estimated

Percent Total (Responses / Estimated) * 100

Progress (bar chart)

For the bar chart, the x-axis is numerical and  the y-axis is category. The X value is set to =Fields.PercentTotal and the Y value is blank.

The problem is that the chart is always blank.

For the 3rd row above I'm expecting a bar that's around 1/3 of the length from 0 to 1. What setting do I need to change to make the bar appear?

Thanks
