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.
Hi there
I'm trying to change the image size of a report when saving it as PNG file. I'm using this code to render the report and save it as PNG file:
private static void RenderReport(){ ReportProcessor reportProcessor = new ReportProcessor(); Hashtable info = new Hashtable(); info["OutputFormat"] = "PNG"; InstanceReportSource reportSource = new InstanceReportSource(); reportSource.ReportDocument = new BucherLabel(nSalDocInternalNo, nSalDocItemInternalNo, nSalDocItemNo); reportProcessor.RenderReport("IMAGE", reportSource, info, CreateStream, out string docName); CloseStreams();}private static Stream CreateStream(string sFileName, string sExtension, Encoding encoding, string sMimeType){ string sPath = $@"K:\Daten\SRM\FileOrder\{nSupplNo}\Labels\"; sFileName = $"{nSalDocInternalNo},{nSalDocItemInternalNo}"; if (!Directory.Exists(sPath)) Directory.CreateDirectory(sPath); string sFilePath = Path.Combine(sPath, $"{sFileName}.{sExtension}"); FileStream fs = new FileStream(sFilePath, FileMode.Create); lStreams.Add(fs); return fs;}private static void CloseStreams(){ foreach (Stream s in lStreams) s.Close(); lStreams.Clear();}It works pretty fine. But I don't know how to set the filesize. Is this even possible?

Hi Team,
I am using Visual studio 2017 for designing Class Library Report (.cs) in my project.
And wanted to create template for Header and Footer, So I can use that in multiple Reports, but i couldn't find any solution in visual studio.
But it looks there is some option in Standalone designer tool that I am not using.
Please guide.
Thank you!

Hello, I have a string representation of the date - "01.02.2016", and I need to cast it to datetime with specific pattern "dd.MM.yyyy" to prevent wrong casting in another culture settings (e.g. en-us which will interpret it by pattern "MM.dd.yyyy").
How can I do this?
Thanks a lot!
My report pulls 6 months, on the first to the last day for each month, of data from the past using a data picker and will use all 6 for one of the graphs, but I also want to use only the last full month of data for all of the rest of the graphs so I need to filter the 6 months to get that data. I am trying to filter only the data for the last month using the date from the parameter but for this I will need the date parts because I want from the first day of the month to the last day of the month. Can someone please give me an idea how I can do this?
ie.
Date Picker chooses 3/5/2019 meaning getting data for all days in each month of Oct, Nov, Dec, Jan, Feb, Mar
One report uses all 6 months
All other reports use only data from March
Any help would be greatly appreciated.
Hi
We're using dynamic column sorting in telerik report. But every time we click on the sort button the report calls the data source. Is there a way to avoid it. This happens when we render the report in different format(csv, pdf) too.
