Hi,

I am using HTML 5 report viewer in my web site which has a fixed width of 1024px. I want my reports to occupy full width of the report viewer and fits on to an A4 sheet when printing.

 I have adjusted the columns to fit an A4 sheet but this makes the report to only take half of the report viewer width. How can manage both layouts?

Using Telerik.Reporting, Version=8.1.14.804.
Visual Studio solution in C# with report designer.
Data from database returns column 'Field1' of SQL type REAL.
Textbox on report with expression : 
= Abs(Fields.Field1)

In preview a red exception box is shown with message : 'Specified cast is not valid.'

As a workaround we now have:

= Abs(CDbl(Fields.Field1))

Should it work with a real (Single in C#?) from the database? Or are we doing something wrong?

I am building a report which is going to be used as a sub-report from within several other master reports.  The sub-report is pretty simple: one Table in the details section bound to a data source displaying a bunch of records, and a few header rows displaying column headers.  I want to include a header which displays some information about the records on the page such as 'Records #1 through #20" on page 1 and "Records #21 through #40" on page 2, etc.  This seems like the perfect application for the 'PageExec' function, however since I am using this as a sub-report anything in the Page Header and Footer will not be displayed.  Is there a way to do such a header value on each page of a sub-report?

I also tried looking into using the 'RunningValue' function but was unable to figure out a 'scope' value which would allow me to do such a thing.  Is it possible via some other method?

Hi! I am new to telerik reporting and creating simple report using stored procedure which takes one parameter. I am designing my report in standalone report designer using sqldatasource and using generated .trdx file in my ASP.Net MVC application in VS 2012. I already tried to create simple report using sql query/ stored procedure without parameter as shown in your article, this works great but when I am trying to use stored procedure with parameter it's not working. Report content like header and other static information is displaying in report but data coming from stored procedure is not displaying. There is no issue in Stored Procedure as I checked it's working in Sql server. I am using following code to pass parameter

@{
        var DataSource = new UriReportSource() { Uri = ViewBag.TemplateName };
       DataSource.Parameters.Add(new Telerik.Reporting.Parameter("SiteID", 1));        
    }

    @(Html.TelerikReporting().ReportViewer()    
       .Id("reportViewer1")
       .ServiceUrl("/api/reports/")
       .TemplateUrl("/ReportViewer/templates/telerikReportViewerTemplate-8.1.14.804.html")
       .ReportSource(DataSource)
       .ViewMode(ViewModes.INTERACTIVE)
       .ScaleMode(ScaleModes.SPECIFIC)
       .Scale(1.0)
       .PersistSession(false)
       ) 

This is working code and works with sql query/stored procedure without parameter but not working when I use stored procedure with parameter. 

Thanks......

Hi everyone,
I am deploying a custom winform application that will use a database table to lookup reports that a user is allowed access to.
The table is just 3 fields
rptID, rptName, and rptDescription

On load of the Report  Form I query the database using the users ID and pull in the 3 fields above to create a group of radio buttons on the form.
What I need to be able to do is then load another form with a reportviewer on it when the user selects a radio button.

Is there anyway to take the string value of rptName and dynamically load it into the ReportViewer on the called form?

I am using instancereportsource with a compiled DLL of reports.

I can hard code the reports and use a Select Case on reportname but I would rather have it be dynamic so that I can add reports later on after the application is deployed by just replacing the reports DLL file.

The code I currently use for the hard coded select case is
Select Case ReportName
            Case "IncidentListingReporting" 
                Dim FullnameRpt2 As New Telerik.Reporting.InstanceReportSource 
                FullnameRpt2.ReportDocument = New Reporting.IncidentListingReport
                FullnameRpt2.Parameters.Add(New Telerik.Reporting.Parameter("SDate", Param2))
                FullnameRpt2.Parameters.Add(New Telerik.Reporting.Parameter("EDate", Param3))
                FullnameRpt2.Parameters.Add(New Telerik.Reporting.Parameter("PNUM", Param4))
                ReportViewer2.ReportSource = FullnameRpt2
End Select

What I would like is to be able to do something like
                FullnameRpt2.ReportDocument = Param1

Thanks for any help!

Help me.

The Export options are missing from the Report Viewer - I'm using the HTML5 Report Viewer.  The icon is visible but clicking it does nothing. 

I can successfully call api/reports/formats and see the available formats in the returned json
I have references to DocumentFormat.OpenXML and Telerik.Reporting.OpenXmlRendering

According to the docs this is enabled by default, so what am I missing?
