Hi,

Can anyone tell me how to create a report using Microsoft report viewer ....

I need to bind the report using code behind....

I tried creating but its giving error....

Code:

  Dim report As ReportDataSource
    Dim ds As New DataSet1
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Local
        ReportViewer1.LocalReport.ReportPath = "C:\Documents and Settings\Murali\My Documents\Visual Studio 2008\WebSites\WebSite3\Report2.rdlc"
        ReportViewer1.LocalReport.DataSources.Clear()
        ReportViewer1.LocalReport.DataSources.Add(New Microsoft.Reporting.WebForms.ReportDataSource("ds", ds.Tables(0)))
        ReportViewer1.DocumentMapCollapsed = True
        ' ReportViewer1.Reset()

Error : A data source instance has not been supplied for the data source 'DataSet1_CountryMaster'.
