export table data to excel in telerik report viewer Chart Item

Hi Telerik,
I have a report viewer that display database table in Chart Item format.
When using the Export function(for example export to excel) in the reportviewer, I got a excel file, which will have chart Item inside.
Right now, instead of the chart item in the exported excel file, I would like the actual database table content to be exported to the excel file. Can I make this work and how to make it work?

Thanks a lot!

multiple columns in report

Hi,

It seems it should be so simple to get multiple columns in a report

The online demo at

http://demos.telerik.com/reporting/examples/producttags/defaultcs.aspx

supposedly shows multiple columns but I can't see any.

I have created the simplest report I can think of, ie a text box in the heading & text box in the detail.
The text box in the detail is 2 cm wide & the report width is set to 6 cm so no overlaps as per tutorial suggestion so I would expect to get at least 2 columns on the page (yes the number of columns is set to 2)

I cannot get it to print multiple columns.

Any suggestions?

Thanks,

Andreas

No Data When Silverlight OnNeedDataSource

Hi,

By setting the DataSource in my server-side Report constructor, I am able to retrieve the report in my Silverlight viewer.

In order to pass in parameters, I understand that I am supposed to set the DataSource to null in the constructor and override OnNeedDataSource.

When I do this and set the DataSource in OnNeedDataSource, the report displays within the Silverlight client with no data at all.

        public OperatingIndicators()        // CTOR
        {
            InitializeComponent();
            DataSource = null;
        }
        protected override void OnNeedDataSource(object sender, EventArgs e)
        {
            this.DataSource = GoGetMyData();
        }

Using the debugger, I see that OnNeedDataSource is called and I can see that the parameters are passed in successfully and the DataSource is correctly loaded with data.

I am using Telerik.Reporting.Service.ReportService, version 3.2.9.1211 on the server.
and Telerik.ReportViewer.Silverlight version 3.2.9.1211 on the client.

Telerik Reporing & RAD Docking in a same WPF window?

Hi, I'm building a WPF application, using Telerik Reporting and RAD Docking control for WPF.

I'm nesting the ReportViewer for Windows forms in WindowsFormsHost. In the same window I put a RadDocking functionality. When I try to unpin and change the position of a pane, the WindowsFormsHost control have overlapped the DockingCompass and the Pane itself.

I have read that a hosted Windows Forms control is drawn in a separate HWND, so it is always drawn on top of WPF elements. Is there a some kind of workaround or WPF release of ReportViewer coming soon?

PDF Generation?

Hi,

We need to generate a PDF on the fly based on an existing template. This will operate on ASP.NET, possibly within Windows Workflow.

I see creating the template of the page in Telerik Reporting, and populating the (simple) fields in the page, then exporting the result to PDF, saving on the web server for onward email.

Is this possible within Telerik Reports? I do not want user interaction, so no Report Viewer is wanted. Just a Report that I can design, compile, populate a few fields and generate a PDF automatically.

Is this possible with your product?

Thanks,

Nathan
