Behavior in changing report

[black_sun]

Hi,
I'm trying to use Report rdcl but i have a problem.
Here is the code:

Private Sub Report_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
DatiBindingSource.DataSource = FrmMain.anno
End Sub

Private Sub RadioButton1_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles RadioButton1.Click
Me.ReportViewer1.LocalReport.ReportEmbeddedResourc e =
"WindowsApplication1.GraficoTrend.rdlc"
Me.ReportViewer1.RefreshReport()
End Sub

Private Sub RadioButton2_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles RadioButton2.Click
Me.ReportViewer1.LocalReport.ReportEmbeddedResourc e =
"WindowsApplication1.GraficoLinee.rdlc"
Me.ReportViewer1.RefreshReport()
End Sub

The problem is that the second report I choose it not appears. Only
the first report I choose appears :-(

Why? Where do I do a mistake??

Thanks in advance.

Bye BlackSun
