Hi,

When creating a report programmatically, using the old charts for reporting I could populate the data for the chart directly using eg. series.Items.Add(mydataitem) - this way I could build a chart by simply inserting data items manually without any datasource. I am now using the new Graph object and I cannot figure out how to dot his - is it even possible?

Hi,

I have a custom resolver working with my html report viewer to display trdx's just fine. Some reports though are not trdx though so I will create these purely in code (in my resolver?) and pass the report to the viewer. I have tried the code below and it seems to work but I just need to confirm that I am doing it the correct way?

ie. is it correct to return a report object instance from the custom resolver?

public class MyResolver : IReportResolver
{
    public Telerik.Reporting.ReportSource Resolve(string report)
    {
        Report rpt = new Report();
 
        ObjectDataSource ods = new ObjectDataSource();
        ods.DataSource = GetSomeData();
        rpt.DataSource = ods;
     
    /*
    ...code to set up report items...
    */
             
        return rpt;
}
 }

Hi,

We are evaluating telerik reports.

The below code snippet is defined in the Report Controller. Report works fine. But when a report is generated, the number of open connection of the telerikSession (used only for cache) is high and they do not get closed. I tried with one user, running one report and the number of openconnections is 30. Can you help me sort out this issue?

static ReportServiceConfiguration preservedConfiguration;
static IReportServiceConfiguration PreservedConfiguration
{
get
{
if (null == preservedConfiguration)
{
preservedConfiguration = new ReportServiceConfiguration
{
HostAppId = "ABC",
Storage = new MsSqlServerStorage(ConfigurationManager.ConnectionStrings["TelerikSession"].ConnectionString),
//Storage = new FileStorage(),
ReportResolver = new OrgnResolver(),
ReportSharingTimeout = 0,
// ClientSessionTimeout = 15,
};
}
return preservedConfiguration;
}
}

Thanks

If I have the Reporting WebAPI setup so that it's working, ie http://localhost:56200/api/v1/report/ is returning:

[{"name":"PDF","localizedName":"Acrobat (PDF) file"},{"name":"CSV","localizedName":"CSV (comma delimited)"},{"name":"XLS","localizedName":"Excel 97-2003"},{"name":"RTF","localizedName":"Rich Text Format"},{"name":"IMAGE","localizedName":"TIFF file"},{"name":"MHTML","localizedName":"Web Archive"},{"name":"XPS","localizedName":"XPS Document"}]

What would cause a 404 when attempting to retrieve a template? ie:

http://localhost:56200/api/v1/report/resources/templates/telerikReportViewerTemplate-html

Hey my headers sometimes are not attaching to a csv export at work. I am doing nothing differently. Example of scenario today. Logged in exported to csv and worked no problem. Reset the application repeated exact same steps with no difference and no headers. I've attached screenshots of the problem. Any pointers on how to fix this would be greatly appreciated.

In crosstab when I set the angle to 270, the text alignment is ignored and is always right aligned. Please see the attached screenshots. Is there a way for the report to actually align as set on design?

Can anyone explain the paging that is happening in this report?

Ive set KeepTogether = false everywhere I can think of. Also Group Keep Together is false.

But it is still throwing pages as if KeepTogether was true in some places.
