Good afternoon,

After my initial problem here: http://www.telerik.com/community/forums/reporting/telerik-reporting/error-adding-new-telerik-report-to-solution.aspx I have finally gotten around to trying to add a new Telerik report to an existing WPF .NET 4 application I have written.

The problem I now have is that the DataSource wizard doesn't seem to pick up any of my datasets or entity models. If I tell the report wizard to create a new one, it doesn't even pick up my connection string from the project settings and I have to manually add it. 

Once the connection string is added, the next screen does not show any of the objects in my SQL database.

Am I way off here with what I should be doing or do I perhaps have a problem that is / isn't related to my original problem?

I'm really disappointed that I can't get this working yet but I'm afraid I will not be purchasing this Telerik reporting option until I am up and running correctly despite I think that it looks like the best reporting option available for my WPF applications.

Thank you,

Paul Pitchford.

Hi,

I am using telerik repotrviewer for reports and here is my code that dynamically accessing report and assigning to reportviewer.
When I run the application I am getting the following error message.

"Exception has been thrown by the target of an invocation."

Here is my code:
            Type reportManagerType = typeof(ReportClass);
            _reportAssembly = reportManagerType.Assembly;
            string assemblyName = _reportAssembly.GetName().Name;
            _reportName = String.Concat(assemblyName,".", _currentReportInfo.Name);
            _reportType = _reportAssembly.GetType(_reportName);
            _report = (IReportDocument)Activator.CreateInstance(_reportType);
               
            IReportDocument report = (IReportDocument)Activator.CreateInstance(_reportType);
            this.DefaultReportViewer.Report = report;

Please help me...

Hi,

Dear Telerik,

could you please consider supporting either <sub> <sup> tags or the css veritical-align attribute for the htmlTextBox.   We write a lot of reports that require footnotes and hence it is useful to subscript parts of the text in a report to achieve this.

Thanks,
Jason

Dear Telerik Team member,

 I am using Telerik report viewer with entity fraework.
This is the code I am using to bind the report to the control.
When I run the app. I am unable to see the result on the reportviewer, but I am able to get the result set from database.
Where am I doing wrong?
Help me please...

Hi all,

My scenario is to place a picture, uploaded by a user.
The picture can be any size, so, I want it to show as much of it as possible.

I have tried different sizetypes, and autosize seems to work the best for me.

The problem - which is a big issue - is, when the picture is wider than the page size. It makes the document contain blank pages on every other page, except the page with the right part of the picture.
This behavior is natural...

What I wanted the most, is some kind of maxsize along with the autosize setting.
Or is there an other recommandation.

Kind regards,
Morten

Hi,

I've been searching online for solutions that can solve my problem but most had to do with Master Details relationships.

My problem in a nutshell.

I have one Master report, the header and footer are populated with one datatable named CompanyInformation. In the details section, I have a telerik.reporting.processing.table, I set the headers and inside the table cells I drag a textbox. I set the value of the textbox to be the corresponding field from the database starting with "[=Field.something]." I bind the header and footer alright but the table will not show up at all and yes the visibility is set to true. By the way, both the master and table datasources are being set at runtime determined by a parameter passed from within an asp.net application.

heres my code.

    private void TelerikReportInvoice_NeedDataSource(object sender, EventArgs e)
        {

            int param = (int)this.ReportParameters["param "].Value;

            InvoiceDataSetTableAdapters.GetOrdersTableAdapter adapter = new TelerikReport.InvoiceDataSetTableAdapters.GetOrdersTableAdapter();
           
InvoiceDataSet.GetOrdersDataTable dt= new InvoiceDataSet.GetOrdersDataTable();
            dt= adapter.GetData(param);

            ((Telerik.Reporting.Processing.Report)sender).DataSource = dt.AsDataView();

        }

        private void table2_NeedDataSource(object sender, EventArgs e)
        {
            InvoiceDataSetTableAdapters.GetOrderFeesTableAdapter adpt = new TelerikReport.InvoiceDataSetTableAdapters.GetOrderFeesTableAdapter();

            InvoiceDataSet.GetOrderFeesDataTable dt= new InvoiceDataSet.GetOrderFeesDataTable();

            int param = (int)this.ReportParameters["param"].Value;  //same as master parameter

            dt= adpt.GetData(param);
            table2.DataSource = dt.AsDataView();

        }

I set both the table and report's datasource to be null in the constructor after initializecomponent() is called. The DataSet Visualizer also shows that there are 2 rows in the datatable returned and i'm also using stored procedures.

Thanks.
