[RESOLVED] rdlc Report not displaying correctly - top part missing

Sorry for displaying such large images but I wanted to show the problem - I've tried before to describe it in words and got no response.

When I run my report the first time it displays correctly - see below.

If I run the report a second time, sometimes it does not display all the report - the top part is missing - see below (here I have run it on a different person).
Attachment 99339

I have found the only solution is to exit the option completely and run the report again - you can see the report is now correct - see below
Attachment 99341

There must be some initialisiation missing.

I do have

Code:

---

ReportViewer1.Reset()

---

On the report form load.

Can you suggest what I am doing wrong or suggest where I can look for more help.
Thanks

Sorry, don't have an answer, but you should post the code that displays the report and explain where the code is located.

Here is a cut down version of the code.
There are two global variables:
'MyReport' which is the name of the rdlc file,
and 'query' which is the SELECT statement used.
When you run it it is OK the first few times then the top of the report is missing.

Code:

---

Option Strict Off
Option Explicit On

Imports System.Windows.Forms
Imports System.Data.SqlClient

Public Class frmReport

    Private Sub frmReport_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        Dim AppPath As String

        AppPath = Environment.CurrentDirectory()

        ReportViewer1.Reset() ' this is important
        ReportViewer1.LocalReport.DisplayName = MyReport
        ReportViewer1.LocalReport.ReportEmbeddedResource = "MIS." & MyReport & ".rdlc"
        ReportViewer1.ProcessingMode = Microsoft.Reporting.WinForms.ProcessingMode.Local
        ReportViewer1.LocalReport.ReportPath = AppPath & "\" & MyReport & ".rdlc"
        ReportViewer1.LocalReport.SetParameters(New Microsoft.Reporting.WinForms.ReportParameter("MyParam1", MyParameters(0)))

        Me.Size = New Size(1030, 600)    ' A4 landscape

        ReportQuery = query

        ' create a data adaptor
        Dim da As SqlDataAdapter = New SqlDataAdapter(ReportQuery, SQLConnection)
        ' create a new data set
        Dim ds As DataSet = New DataSet
        ' fill the data adapter
        da.Fill(ds)
        ' clear the datasource
        ReportViewer1.LocalReport.DataSources.Clear()
        ' set the dataource (DataSet1 is defined in the matrix in the rdlc file)
        Dim rds1 As New Microsoft.Reporting.WinForms.ReportDataSource("DataSet1", ds.Tables(0))
        ' add a new datasource
        ReportViewer1.LocalReport.DataSources.Add(rds1)

        ReportViewer1.RefreshReport()
    End Sub

End Class

I have done some more work and can now reproduce the problem.
If you display a report and scroll down on the report.
When you display the next report the top is missing and it is impossible to scroll up to it.
If you print the report it is all there but it is not displayed in the report viewer.

A colleague has had a look at it and he thinks it is caused by AutoSizing - I have autosizing set to false on bothe the form and the report.
If you set Autosize to true it does not autosize.
This is why I programatically set the size for portrait and landscape reports.

It is nothing to do with autosizing.

It also occurs when I scroll to the right - when I run the report again I cannot access what was to the left.
The problem may be to do with resetting the scroll position.

I have tried setting the AutoscrollPosition and the AutoScrollOffset to zero but that has no effect

Code:

---

ReportViewer1.AutoScrollPosition = New Point(0, 0)
ReportViewer1.AutoScrollOffset = New Point(0, 0)

---

I tried to trap the scroll events but this code is not accessed when the user scolls the report.

Code:

---

Private Sub ReportViewer1_Scroll(sender As Object, e As System.Windows.Forms.ScrollEventArgs) Handles ReportViewer1.Scroll
 End Sub

---

Do you close "frmReport" before you run the second report?

Yes, I close it using the 'x' button on the top right of the form.
There is no extra code to close it.
When I run the report again I load the form again.

I have at last managed to fix this, I added ReportViewer1.RefreshReport to the FormClose event.

Private Sub frmReport_FormClosing(sender As Object, e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Me.ReportViewer1.RefreshReport()
End Sub

Glad you got it solved, doesn't seem that should be necessary but at least it works. I also noticed you use a Me.ReportViewer1.RefreshReport() in the form load event. Have you tried just showing the report instead of refreshing.
