Design Time Problems. ReportSource property from the ReportViewer property grid does not show available reports

Environment

Progress® Telerik® Reporting

Description

I want to show my report in a ReportViewer control, but when I click on the arrow in the ReportSource property from the property grid, it does not show available reports - what is wrong?

Solution

Follow our best practices and have the report in a separate class library that is referenced in the application or website. Check if the class library containing the report is referenced in your application/website and that you have rebuilt the application/website.

The most reliable way to specify a report for the ReportViewer is to do this programmatically. For example, if you're using the ASP.NET Web Forms Report Viewer, on the Page_Load event of the page:

CSharp

protected void Page_Load(object sender, EventArgs e)
{
	if (!IsPostBack)
	{
		var typeReportSource = new Telerik.Reporting.TypeReportSource();
		typeReportSource.TypeName = "Telerik.Reporting.Examples.CSharp.ListBoundReport, CSharp.ReportLibrary";
		this.ReportViewer1.ReportSource = typeReportSource;
	}
}

VB

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
	If Not IsPostBack Then
		Dim typeReportSource As New Telerik.Reporting.TypeReportSource()
		typeReportSource.TypeName = "ListBoundReport, VB.ReportLibrary"
		ReportViewer1.ReportSource = typeReportSource
		ReportViewer1.RefreshReport()
	End If
End Sub
