I have a problem in my RDLC Report. The report header is displaying whilst the report details are not.

Report Layout:

Name:  1.jpg
Views: 73
Size:  6.1 KB

Report Output:

Name:  2.jpg
Views: 71
Size:  9.3 KB

As you can see I've already called the SQL fields in the report layout and the report output does not display any data.

I use 2 forms: Form 1 is the generation of data whilst Form 2 is the Report Viewer.

This is a part of my code in Form 1 (Generation of Data):

Code:
Private Sub btnGenerate_Click(sender As Object, e As EventArgs) Handles btnGenerate.Click

    Dim rprtName As String

    If lstReports.SelectedIndex = 0 Then
        rprtName = "rprtIS"
    Else
        rprtName = ""
    End If

    Dim frmrpt As New frmReportViewer

    frmrpt.ismo = cbMonth.Text
    frmrpt.isye = cbYear.Text
    frmrpt.strReport = rprtName

    frmrpt.ShowDialog()

End Sub
This is the sample code for the Report Viewer form:

Code:
Private Sub frmReportViewer_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    Dim rprtDataSource As ReportDataSource

    Try
        With Me.rprtViewer.LocalReport
            .Refresh()
            .ReportEmbeddedResource = "REPORTTESTING1." + strReport + ".rdlc"
        End With

        Select Case strReport
            Case "rprtIS"
                Dim ds As New REPORTTESTING1.ds_spIS
                Dim da As New REPORTTESTING1.ds_spISTableAdapters.SP_Select_Invoice_SummaryTableAdapter

                ds.Clear()

                rprtDataSource = New ReportDataSource("dsIS", ds.Tables("SP_Select_Invoice_Summary"))
                Me.rprtViewer.LocalReport.DataSources.Add(rprtDataSource)
                da.Fill(ds.SP_Select_Invoice_Summary, ismo, isye)

        End Select

        Me.rprtViewer.SetDisplayMode(Microsoft.Reporting.WinForms.DisplayMode.Normal)

    Catch ex As Exception
        MessageBox.Show(ex.Message, My.Application.Info.Title, MessageBoxButtons.OK, MessageBoxIcon.Error)
    End Try

End Sub
Thanks in advance,
