I've upgraded my reporting component to 7.0.13.426 already.  Noticed this issue in IE 10 with version 6.2.12.1017.  When I open a report that uses the web viewer it displays fine and exports to PDF fine, but when I attempt to export the exact same report to RTF I get an exception error.  This is happening over all our reports that render in the report viewer.

Using Visual Studio 2012 and ASP.net (Frame work version 4.0).

Web.config report settings as follows:

<Telerik.Reporting>
    <Extensions>
      <Render>
        <Extension name="IMAGE" visible="false" />
        <Extension name="RTF" visible="true" />
        <Extension name="PDF" visible="true">
          <Parameters>
            <Parameter name="FontEmbedding" value="Subset" />
          </Parameters>
        </Extension>
        <Extension name="HTML" visible="false" />
        <Extension name="MHTML" visible="false" />
        <!--Added Bug 4420 - CCM Dec 7, 2012-->
        <Extension name="XLS" visible="false">
          <Parameters>
            <Parameter name="UseNativePageHeader" value="false" />
            <Parameter name="UseNativePageFooter" value="false" />
            <Parameter name="ShowGridlines" value="true" />
          </Parameters>
        </Extension>
        <Extension name="CSV" visible="false" />
        <Extension name="XPS" visible="false" />
      </Render>
    </Extensions>
  </Telerik.Reporting>

Hi!, I´m having problems with my report. We didn´t update anything from the report since April, it was working fine but since last week it stoped working. In the production server the report loads almost fine the first time (Some images are missing), but when you navigate to the second page of the report you get a "Session expired" message.
I tried running the project locally using the production connection and i get a "exception has been thrown by the target of an invocation" message. The report´s preview works fine. Im using Stored procedures. 
I changed the connection string and used the development SQL Server connection and the report works , so I suspect it may be a data Issue but I get that generic error and I can´t know with precision what is causing it.

Can you help me?

Regards.

When I try and insert a report viewer control, it says "Failed to create designer....".  All of the other Telerik reporting controls are also greyed out.  I've reset the toolbox but the issue remains.  Do I need to reinstall the reporting app?

I have nested lists in 3 levels in my detail section. When the innermost list is very big, then is forces a page break. it forces a page break.

list 1 has only 1 line - print on top of page 1
list 2 has only 1 line - prints on top of page 2
list 3 has 200 lines - starts printing on top of page 3 and runs over 2 pages pages

I need list 1,2 and 3 to start printing underneath each other on page 1.

I have set keeptogether to false on all 3 lists, with no luck.

Please help

We'd like to replace the default functionality for the Excel export button on the HTML report viewer.  We'd like to write a custom method for each report that will export the underlying data to spreadsheet in a format that is conducive to sorting, totalling, etc. via Excel.  We don't need to export the headings, totals, etc.

Can we override the default behavior? 

 

Hello,

I'm new to Telerik Reporting. Is it possible to force parameter fields to be displayed on an new line. In my case the parameters are placed after each other (by 2) . I've 5 parameter fields and I want them to be displayed like:

ParameterField1
ParameterField2                ParameterField3
ParameterField4                ParameterField5

Please let me know how to achieve this.

Regards,
  Jos.

Hi,

I am trying to use column groups and row groups to pivot the data programatically. Following is the code snippet I am working on
             crosstab1.RowGroups.Add(tableGrouprow);
                textboxGroup1 = new Telerik.Reporting.TextBox();
                textboxGroup1.Style.BorderColor.Default = Color.Black;
                textboxGroup1.Style.BorderStyle.Default = BorderType.Solid;
                textboxGroup1.Value = "=Fields." + ds.Tables[0].Columns[0].ColumnName;/***giving column index on the column we want to group****/
                textboxGroup1.Size = new SizeU(Unit.Inch(1.1), Unit.Inch(0.3));
                tableGrouprow.ReportItem = textboxGroup1;

but i am unable to do grouping.I have attached the screen shot of the table I want to pivot.I want pivot on month(column group) and drug(row group).I couldn't find any sample projects on this.can you please give some hint on this or a working sample would be more useful.

Thanks you..

Hi

I'm trying to apply some custom date formatting.
So I have created a method to format the date (where parameter dt is the Field from the database)


And for the expression I wrote:


If a DBNull value is returned from the database then I get the error "The expression contains undefined function call FormatDate()."

I don't understand why the error is occuring when I am using the IsNull() function.
