MultiVaule supported in Oracle stored procedure?

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

Changing the name of a Pie Graph causes error

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.

Render report as PNG and set image size

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?

Regards,
Roman

Cast string to date with specified pattern

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!

Saving Report Parameters

I want to be able to save report parameters the user has chosen and save them. Later the user can select the saved report and I'll run the report and fill in the (many) parameters at run-time. I came across this post written almost 2 years ago:

http://www.telerik.com/community/forums/reporting/telerik-reporting/saving-report-criteria.aspx#1736100

Does the Telerik Report Viewer expose an event or object which would allow me to grab these values? The only workaround I could see was to grab the data from the drop downs themselves. Using jQuery I wrote this as a simple test on a button click:

    $("iframe[id$='ParametersArea']").contents().find("select").each(function (index) {
        alert( $(this).val() + " | disabled: " + $(this).is(':disabled') + " | id: " + this.id);
    });

The only other option is to build my own Parameter sections from scratch (20 reports with up to 8 parameters each, oh joy).

Please let me know if anything has changed in the past to years in this regard,

Thank you

Filtering data using date report parameter

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.

Dynamic Sorting Calls The Data Source

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.

Regards,

Majar

Connection string in Asp.Net Core

I have an Angular / Asp.Net Core web application. The report viewer component is working in the Angular application. Parameters are passed correctly. But when the report is loaded I get the error message in the viewer:

An error has occurred while processing Table 'crosstab1': Invalid key value.

The passed parameters values are displayed in textboxes so the report is loaded and rendered.

I guess it has something to do with the connection string that cannot be found.I created the report in the Report Designer application (so no class library/project which contains the reports) and the name of the connection string is "Reports" in the designer.

In the appsettings.json file I added an entry into the ConnectionStrings section with the name "Reports" (just as in the examples)

"ConnectionStrings": [

{"name": "Reports",     "connectionString": "Data Source=.;Initial Catalog=DatabaseName;Integrated Security=True",     "providerName": "System.Data.SqlClient"   }

]

I also created an app.config file with the connection strings

<?xml version="1.0" encoding="utf-8"?>

<configuration>

<!-- To customize the asp.net core module uncomment and edit the following section.

For more info see https://go.microsoft.com/fwlink/?linkid=838655 -->

<!--

<system.webServer>

<handlers>

<remove name="aspNetCore"/>

<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified"/>

</handlers>

<aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />

</system.webServer>

-->

<connectionStrings>

<add name="Reports"

connectionString="Data Source=.;Initial Catalog=DatabaseName;Integrated Security=True"

providerName="System.Data.SqlClient" />

</connectionStrings>

</configuration>

It seems that the Report Engine cannot find the connection string. Or does the Report Engine use another name for finding the connection string?
