Hello

We are using Telerik Reporting 2011 Q3.
 
When viewing on a computer (IE, Safari, Chrome, FF) we have some reports that display within a viewer that is set to a certain size, and will use scrollbars if needed.

When viewing the same reports on an Ipad (Safari), the viewer has lost the scrollbars and has grown big enough to accommodate the report. 

Any ideas as to how we can stop the viewer from resizing itself on the ipad?

Thanks

Cheryl

In my asp.net webforms or my Silverlight app, I can't resolve InstanceReportSource.

I have the latest Q2 2012 and ran both solutions through the upgrade wizard.

Also, I can see my report in the asp.net webform, but not the siverlight version after my upgrade to q2 2012.  My configs and dlls are up to date.  I'm not using InstanceReportSource for my silverlight report viewer, but I don't think you're supposed with that right?  That's only for WPF and asp.net.  Not being able to see the error message in silverlight is maddening, I'm 90% away from giving up on the silverlight viewer and always popping up a web browser report.

For silverlight I'm still using 
            repViewer.Report = "MyReportsNameSpace.MyRepor1, MyReportsNameSpace";
            repViewer.RenderBegin += new Telerik.ReportViewer.Silverlight.RenderBeginEventHandler(repViewer_RenderBegin);
...

Refresh button is not working in my report.I use report viewer to display report (in asp.net mvc).When i hit the refresh button it didnot get latest data.What is problem in my code.

Telerik.Reporting.ObjectDataSource objectDataSource = new Telerik.Reporting.ObjectDataSource();
objectDataSource  = getData();

 Reports.MyReport report = new  Reports.MyReoprt();
 report.DataSource = objectDataSource;


 ReportViewer1.Report = report;
 ReportViewer1.RefreshReport();

I have a client who is happy with Telerik apart from the fact that the charts are rendered as images - this means there is no mouse hover functionality available.

Is it possible to render the charts as SVG or Canvas? If not, is it possible and/or feasible to embed Google charts into the report. I noticed that there is an HtmlTextbox control that in theory I could use.

Hi..
1. I get outofmemory exception on large reports over  500+ pages.
2. When I include a Chart and have have more than around  5000+ items  (datapoints) I get a chart outofMemoryExceptions

any ideas?

Hello,

 I am not able to properly bind a DataTable to a report viewer that is embedded within a Sharepoint 2010 WebPart. (using Telerk.Reporting.dll version 6.1.12.820). I have bound the same data to a generic asp gridview without error.

I have followed the deployment/configuration steps for getting the report viewer to work properly within shareopint -- and it is appearing (just the underlying data is not that I'm binding is not).

I have also followed the instructions on how to bind a dataTable to a report viewer with no success.

http://www.telerik.com/help/reporting/object-data-source-how-to-bind-to-data-table.html

I have copied the code directly from this link (replacing the GetData() method with my own to create a simply 3 column, 1000 row table).

{

// Creating and configuring the ObjectDataSource component:

var objectDataSource = new Telerik.Reporting.ObjectDataSource();

objectDataSource.DataSource = createData(); // GetData(); // GetData returns a DataSet with three tables

// Creating a new report

Telerik.Reporting.Report report = new Telerik.Reporting.Report();

// Assigning the ObjectDataSource component to the DataSource property of the report.

report.DataSource = objectDataSource;

// Use the InstanceReportSource to pass the report to the viewer for displaying

Telerik.Reporting.InstanceReportSource reportSource = new Telerik.Reporting.InstanceReportSource();

reportSource.ReportDocument = report;

// Assigning the report to the report viewer.

ReportViewer1.ReportSource = reportSource;

}

protected void Page_Load(object sender, EventArgs e)

if (!Page.IsPostBack)

BindTelerikReport();

}

I would appreciate any help with this. Thanks you!

Hello Telerik Team,

I am presently converting my crystal reports to telerik reports.But previously crystal reports datasource was sql stored procedures and select statements but now
I am planning to have a datasource as sharepoint list.Is there any sample on how we can do that.
I appreciate your help.

Look forward from you.

Thank you
Smith

I am trying to upgrade to Q2 2012 but am getting some obsolete syntax errors (Warning 32 'Public Shared Widening Operator CType(report As Telerik.Reporting.Report) As Telerik.Reporting.ReportSource' is obsolete: 'The implicit Report to ReportSource conversion is obsolete. Please create InstanceReportSource instead.')
.
How do i correct this to use the create InstanceReportSource?
