This is for a .net core 2.2 razor page.

I've tried rerunning the vsix for vs2019, but nothing seems to work. How to get "The HTML5 Report Viewer item template is available in the Add New Item dialog box under the Web category" referenced in the docs at https://docs.telerik.com/reporting/html5-report-viewer-quick-start to show up?

I have found very little in the way of examples that are razor based. Does such an animal exist?

Thanks .... Ed

I have a question that is frustrating me.  I am trying to get up a column chart using the following query

SELECT COUNT(conversation.id) as total_chats, 
       COUNT(lead.id) as total_leads,
       (SELECT SUM(total_visits) 
FROM site_visit INNER JOIN site ON site.id = site_visit.site_id 
WHERE [date] BETWEEN DATEADD(DAY, DATEDIFF(DAY, 0, conversation.conv_start), 0) AND DATEADD(DAY, 1, DATEADD(DAY, DATEDIFF(DAY, 0, conversation.conv_start), 0)) AND site.client_id = @clientId) AS total_visits,
DATEADD(DAY, DATEDIFF(DAY, 0, conversation.conv_start), 0) as date,
        site.client_id
FROM conversation LEFT OUTER JOIN lead on conversation.lead_id = lead.id
                  INNER JOIN site on site.id = conversation.site_id
WHERE site.client_id = @clientId and conversation.conv_start BETWEEN DATEADD(DAY, 1, DATEADD(MONTH, -6, EOMONTH(@date))) AND DATEADD(DAY, 1, EOMONTH(@date))
GROUP BY DATEADD(DAY, DATEDIFF(DAY, 0, conversation.conv_start), 0), site.client_id that runs properly in the query configuration tool and populates the design view as expected as evidenced in the attached screenshots.  But when I attempt to run a preview I get the error shown in the third attachment.

I have checked all of the parameters and don't understand why this error would be coming up.

Thanks you for helping me understand this error.

Hello Telerik Team,

I wanted to install Telerik Reporting 12.2.18.912, but in the Progress Control Panel in Telerik Reporting under "View All Versions" I can only see 2 versions. (See in scrennshot). How can i install the version that I need?

Thank you in advance.

Hello, I need to get the size of textbox programatically but when I use, for instance, textBox.Height.Value I get the rounded number. Is there any way to get the accurate value of textbox size?

Thanks!

Hi, I'm very new to Telerik Reporting so please excuse the very basic question :)

I have a solution with multiple projects. The reports are in their own project.  I am trying to create the report from the website project and send a list of my data type to the objectDataSource of the report so that it can dynamically populate the report table. Then I render the report instance as a pdf to store. 

I am able to call and create the report, but I am having trouble getting the report to populate any data into the table.  The report renders but is blank other than the table headers. 

I am trying to find an example solution that does this using 2 projects, a telerik report, an object data source, and a GetData method that takes in a List<MyData> and returns the List<StuffData> so that the table can be populated. Is this doable or is there a better way to pass a list of data to the report so that it can dynamically populate the table on the report? 

Telerik.Reporting.ObjectDataSource objectDataSource1 = new Telerik.Reporting.ObjectDataSource();
        List<StuffData> stuffDataList = new List<StuffData>();

//This is just an example. The list will be populated from user selections adding to the list. 
        for (int i = 1; i < 3; i++)
        {
            int dummyNumber = 999999999 - i;
            StuffData stuffData = new StuffData()
            {
                stuffAddress = i + "Main Street",
                stuffDataId = i,
                stuffSource = "Source " + i,
                stuffName = "Big Corp #" + i,
                stuffNumber = dummyNumber.ToString()
            };
            stuffDataList.Add(stuffData );
        }

//Class in the report project that contains the GetStuffData method to return the list of stuff.  I couldn't find a way to pass a List<StuffData> in as a report 

//parameter

        objectDataSource1.DataSource = typeof(StuffDataAccess);
        objectDataSource1.DataMember = "GetStuffData";
        objectDataSource1.Parameters.Add(new Telerik.Reporting.ObjectDataSourceParameter("stuffDataList", typeof(List<StuffData>), stuffDataList));

        ReportTemplate.StuffReviewReport stuffReviewReport =
    new ScheduledHearingTemplate.StuffReviewReport();
        stuffReviewReport.DataSource = objectDataSource1;

        ReportProcessor reportProcessor = new ReportProcessor();
        Telerik.Reporting.InstanceReportSource instanceReportSource = new Telerik.Reporting.InstanceReportSource();
        instanceReportSource.ReportDocument = stuffReviewReport;
        RenderingResult result = reportProcessor.RenderReport("PDF", instanceReportSource, null);
       

Thanks in advance. 

I see "Using Multivalue Parameters" document that "The data source cannot be a stored procedure. Telerik Reporting does not support passing a multivalue parameter array to a stored procedure."

I want to confirm if I can pass MultiVaule to Oracle stored procedure in standalone version. 

Many thanks

I am new to Telerik and have run into an issue with the creation of a Pie chart.  I first set my data source groups and run the design mode view to see that the graph looks correct.  I then go to start cleaning things up and rename the graph from graph1 to another name and then run the designer view again to see the error :

An error has occurred while processing Graph 'DeviceTypePercentages':

An error has occurred while processing RangePolarDataPoint:

Scope name 'graph1' does not represent a valid data scope name.

---------InnerException--------

Scope name 'graph1' does not represent a valid data scope name.

Thanks for any help you can provide on this.
