Hi,
I have developed number of projects in Visual Studio 2010 using Telerik Reports  v. 6.2.12.1017 (Q3 2012)

Now I'm using Visual Studio 2012, and want to install the latest version of Telerik Reporting v. 7.0. 13.426 (Apr 26, 2013)

I want to keep the old version for Visual Studio 2010, Because I have tried it before, as in the latest version of Telerik reporting they have obsolete some features from old versions which I have used in most of my Reports. and those projects with old version of Telerik reporting doesn't work with the latest version.
some of then are as bellow

Actually When I try to Install it from Telerik Control Panel, it gives the following warning

* All previous versions installed on the machine will be removed.
"Snapshot is attached"

Is there any way, so my Old Projects should use the old version of Telerik Reporting and New Projects should use the latest one...???

Thanks.

Hi there,

I have an existing view with an view model as the data context, I am adding a report (Telerik Reporting 2013Q1) to the page, I use one of the public properties of the viewmodel as the data source (it's a list of object), but the report is empty seems like there is no data, here is some code:

1. the view
<tr:ReportViewer Name="ReportViewerStrats" ReportSource="{Binding DataContext.ReportSource, ElementName=StratsView}"/>

2. the property view model
private List<MyItem> _myItems;
public List<MyItem> MyItems
{
    get { return _myItems; }
    set
    {
        _myItems = value;                
        base.OnPropertyChanged("MyItems");
    }
}

3. the initialize in view mode:
MyItems = GetItems();   //Get from database
ReportSource = new MyReport();


And finally the report is attached. In debug mode, I check the view model (MyItems) does have data.

thanks.

Is there an option for a slider or something within the reportviewer that shows all the pages but at thumbnails, that once clicked it will jump to that page? In another control we were using it had this option, so I wanted to know if Telerik's reporting tool has this as well or at least a way to emulate it with some other control. Like using a ListBox or something

Hello,

My company just purchased a bunch of Telerik controls. We noticed there was a reporting control so we wanted to take a look at it. Currently we are using Active Reports for all our reports. I was asked to look into what the Telerik Reporting could do for us. I wanted to create a simple report with a few text boxes and a subreport to show data. I am having a hard time though getting data to show in a sub report. I have to set all the report data in a usercontrol file. Since the report would be dynamically filled, I have to reference each control and set the data source to whatever I need. I call my PrepareReport() function to load the data into the report and then stream it. I am able to access my textboxes and set their values and those show fine.The datset below returns 4 records but nothing shows in the subreport when I run it. What am I missing? Any help would be greatly appreciated. I have searched through this forum and google and can't seem to find a solution for what I want to do. Thanks!
private void PrepareReport(Telerik.Reporting.Report rpt)
{
    Telerik.Reporting.DetailSection detail = (Telerik.Reporting.DetailSection)rpt.Items["detail"];
 
    Telerik.Reporting.TextBox txt = (Telerik.Reporting.TextBox)detail.Items["txtDNIdValue"];
    txt.Value = "11111";
 
    Telerik.Reporting.SubReport subRpt = (Telerik.Reporting.SubReport)detail.Items["subReport1"];
 
    DataSet ds = new DataSet();
    ds = FunctionToFillDataSet();
 
    subRpt.Report.DataSource = ds;
}

I have a report with a grouping based on parameter X.  In addition to this grouping, the report will page break after each grouping, so only one value of X will be on a page.  I have a footer in the pageFooter section with the current time and page number, and I want to put the X parameter into the footer.

The X parameter is being put into the footer but only the first instance.  For example, if the X values I have are A, B, C, I have a page for A, B, C but the footer always says A.

My page break occurs after the groupFooterSection for X.

What can I do to get around this problem?  Thanks.

Exporting to Excel takes a long time and I would like to display a message like "Exporting.... Please wait" so the user does not think the web page is frozen. The ReportViewer already has a "Generating Report" message so I assumed it would have a message for exporting. I tried putting the ReportViewer in a RadAjaxPanel and setting a RadAjaxLoadingPanel but no spinning wheel appeared.
 
I am using the latest Telerik Reporting and .Net 4 Framework. Any ideas?

I want to make statements, in ReportViewer shows these controls or label, but these controls or label is hidden, not printing.

Report provides these features, or attribute set?

thank you

I'm using Telerik reports in an asp.net MVC project.

A report I'm trying to generate is failing before it gets started, in the [HttpPost] ActionResult in the Controller; I reckon because "if 
(ModelState.IsValid)" is returning false.

I didn't know what IsValid was; on investigation, I see that it is defined in System.Web.Mvc.ModelStateDictionary

So what are the causes of a ModelStateDictionary being invalid? What should I examine or verify?

Hi All - Im looking at the KB article: The expression contains undefined function call MyUserFunction() error

http://www.telerik.com/support/kb/reporting/designing-reports/the-expression-contains-undefined-function-call-myuserfunction-error.aspx

excerpt ...

PROBLEM
The following error is thrown when running the report: #ERROR# The expression contains undefined function call MyUserFunction()

SOLUTION

This error can occur in any of these three cases:
  1. The class library has not been rebuilt and thus the function does not yet exist.
  2. Using the function with wrong number/type of parameters. The passed fields must match the function signature you've defined originally.
  3. A field specified as function argument is null. Make sure that such cases are handled in the user function.

In my case I think its #3. 

I have a report that uses date ranges to filter data.  if a user select a date range that results in zero records, I get the undefined user function error.  I assume because of the nulls.

#3 above mentions "Make sure that such cases are handled in the user function"  by this assume Telerik means use something to the effect of  ..

If (MyParam==null) {return 0;)

I tried this and still get the error, so I must be doing something wrong.

Could someone please test this and report back?

generate a report with a simple UDF.  pass a null dataset to the report.  Do you get the same error?
