Now previously in our 2012 we were getting something similar to this when a control with the embedded control was displaying a report built inside Visual Studio.  We upgraded to Q3 2013's release, removed the older reports, added a class that builds the XML version (trdx files) and the error went away.  Now a different Out of Memory exception error (listed above) recently started occurring.  Originally the image we used was streamed from the database (for logos) but now they are local to the application (I cannot point to the post, but on your ASP forums, someone suggested doing that with other Telerik controls that used images).  Our app is a desktop app (non-wpf) that uses Telerik Reporting.  The above error only seems to occur in certain situations, so not every time.  it occurs on reports that vary in pages (1-75).  Our reports that go into the reportbook do not have this problem (avg 136 reports totaling ~900 pages).  We have 2 report viewers (2 separate user controls on same form) that display the reports.  One displays a single report while the other display the report book when all the single reports are loaded.

In 2012 release we were getting (using code behind version) about 80% of the clients were getting this error:
​ System.OutOfMemoryException: Out of memory.

Now this could just be me, but I'm starting to think it's not the loading of our logo onto the report, but drawing the report itself since the logo is no longer read from the database but read from file.  In my case, we discovered that working with trdx files are easier to create a dynamic tables than the code behind version.

Here is a sample of how the report is built.

/// <summary>
/// Returns a Telerik Report for use in the Telerik ReportViewer
/// </summary>
/// <param name="reportInfo"> of the report to generate, see ReportInfo class</param>
/// <returns></returns>
public Telerik.Reporting.Report GetReport(ReportInfo reportInfo)
{
#region hallway monitors
if (reportInfo == null)
throw new NullReferenceException("ReportInfo is missing or null.");

if (reportInfo.Name == null)
throw new NullReferenceException("Report Name is missing or null.");

#endregion

XDocument doc = CreateXDocument(reportInfo); //the trdx file

// open the report
BufferedStream stream = new BufferedStream(new MemoryStream());
stream.Write(Encoding.ASCII.GetBytes(doc.ToString()), 0, doc.ToString().Length);
stream.Seek(0, SeekOrigin.Begin);
StreamReader sr = new StreamReader(stream);

System.Xml.XmlReaderSettings settings = new System.Xml.XmlReaderSettings();
settings.IgnoreWhitespace = true;

XmlDocument xmlDoc = GetXmlDocument(doc);
Telerik.Reporting.Report report;

using (System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(sr, settings))
{
Telerik.Reporting.XmlSerialization.ReportXmlSerializer xmlSerializer = new Telerik.Reporting.XmlSerialization.ReportXmlSerializer();

report = (Telerik.Reporting.Report)xmlSerializer.Deserialize(xmlReader);
}

Telerik.Reporting.TextBox tbHeader = (Telerik.Reporting.TextBox)report.Items["pageHeaderSection1"].Items["textBoxHeader"];
tbHeader.Value = reportInfo.Title;

if (reportInfo.CompanyLogo != "" && reportInfo.CompanyLogo != null)
{
Telerik.Reporting.PictureBox pictureBoxCompanyLogo = (Telerik.Reporting.PictureBox)report.Items["pageHeaderSection1"].Items["pictureboxCompanyLogo"];
pictureBoxCompanyLogo.MimeType = reportInfo.CompanyLogoExt != "" ? "Image/" + reportInfo.CompanyLogoExt.ToUpper() : "";
pictureBoxCompanyLogo.Value = Image.FromFile(reportInfo.CompanyLogo);
}

foreach (TableInfo tableinfo in reportInfo.Tables)
{
Telerik.Reporting.Table table = (Telerik.Reporting.Table)report.Items["detailSection1"].Items[tableinfo.ReportTableName];
table.DataSource = tableinfo.DataSource;
}

return report;

}

​ private XmlDocument GetXmlDocument(XDocument document)
{
using (XmlReader xmlReader = document.CreateReader())
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(xmlReader);
if (document.Declaration != null)
{
XmlDeclaration dec = xmlDoc.CreateXmlDeclaration(document.Declaration.Version,
document.Declaration.Encoding, document.Declaration.Standalone);
xmlDoc.InsertBefore(dec, xmlDoc.FirstChild);
}
return xmlDoc;

Hello, I'd like to, using the Standalone Report Designer, Import an existing Visual Studio Report (.cs) and save it as a trdx.

I have seen the following links:

http://docs.telerik.com/reporting/import-report-wizard

and

http://docs.telerik.com/reporting/standalone-report-designer-import-clr-reports

 

They indicate it possible but the second link seems for a different interface than mine. (There is no " In the Open dialog window, select .NET Report Library from the file type combobox. ")

and following the first link leads to an Import Report Wizard but in the "available converters" there is only Crystal Reports. Also the file filter gives no option for extensions other than *.rpt.

 

Do I have to install/ download a .NET converter?

 

I have Report Designer Q3 2015.

 

Thanks,

-Jeff

Hi,

I upgraded my Telerik reporting version to the latest version.

I view reports using the Properties dialogue of a ReportViewer . all worked fine.

but after some reports, suddenly I get this error:

Invalid report type Exception has been thrown by the target of an invocation.

and I do not can see any reports. (all the reports , others too).

Yesterday I get this error all time. Today the reports worked fine' and suddenly I get this error again.

Can anyone shed any light as to the possible reasons why this might be happening?

Thanks

Chani

 

Hello there,

I am using C# .net Winforms Report. 
I have a data set like this

{Code, $dollar}
{0, 100} {0.1 , 125}, {0.2, 127},
{1.2, 250},{1.4,210},
{2.0,250},{2.3,210},
{5.2 , 300}

I tried to make a simplest scatter plot with every dots connect by line. I do not want the category group because if I do, then I will be missing  4, and 6 in x axis. it will have 0, 0.1, 0.2, 1.2, 1.4, 2.0, 2.3, and 5.2 only which is categorized.
I want x's range to be fixed from 0 to 6 with equal space.
scatter plot cannot have series group but line graph requires series group. 

I tried so many different ways but couldn't figure it out.
Can you show me some examples? 

I need to change the column name of the report based on the Day of Week.
I could not find this function on the docs.

net core 5, angular 9, telerik REST service, working fine on local when debug in VS

but after deploy, it  showing loading, then showing No page to display, no error.

tested api/reports/formats working, report calling backend api working, just not showing report.

any help pls

 

We are using the Report Designer V 14.1.20.513. I was hoping for an explanation of sortings. Some of our reports have 10 or more groupings, and sorting doesn't always do what I expect. It seems like I need to duplicate all the group sorting into the program sorting, but I can't tell which one rules in that case. Sometimes in the groups I need to add a 2nd sort from the next group to get the report to work. Can you explain the differences between group and program level sorting.

Thank you.

  

   Is there a way to connect telerik report designer to Cosmosdb

I have a textbox within a table.  I set the background color as test to red and the borders as solid.  The changes are visible in the designer, but get lost when I run the report.  It is only happening with the one textbox.  What is the problem?
