Passing peporting parameters from WindowsForm Codebehind to Report

[Danilo]

Hello,

I'm working on a Windows Forms Application where I want to load Reports into a Reportviewer after a click on a Button.
This is the Event that gets triggered by pressing on the button in the Code behind of the Windows Form:

private void button1_Click(object sender, EventArgs e)

{

 

    Telerik.Reporting.InstanceReportSource reportSource = new

    Telerik.Reporting.InstanceReportSource();

    reportSource.ReportDocument = new Reportlibrary.Report1();

 

    reportSource.Parameters.Add(new Telerik.Reporting.Parameter("OrderNumber","123456789"));

 

    reportViewer1.ReportSource = reportSource;

    reportViewer1.RefreshReport();

 

}

The problem now is that I have no Idea how I can access / get the parameter I added before Refreshing the Reportviewer.
The Report already has set a Datasource. I don't know if this matters.
This is what I have right now. I've tried everything and I'm just not getting further.

public Report1()
        {
            InitializeComponent();

            Position[] all = new Position[]{

               new Position("Test", "Test","test"),

            };

            this.DataSource = all;

             MessageBox.Show("Number: " +
             this.Report.ReportParameters["OrderNumber"].Value.ToString());

        }

Is there any way to get this parameter straight after InitializeComponent(); ?
Do I need to add another Event to the report to access it? If yes which on is the best way to do this?

Any help very apreciated.
Thank you

Still no Progress. Anyone any idea?

Thanks

Hi Danilo,

We have reviewed your code snippet and noticed that you invoke the report constructor prior setting the report parameter value.

Generally the report parameters are designed for use in expressions. Thus in order to advise you appropriately we will appreciate if you elaborate further on your requirement.

Additionally you may find useful the Report Life Cycle help article.

All the best,
