My problem is specific to the ReportViewer control. The report displays correctly in every other way (ssrs server viewer, visual studio preview, visual studio 'Run', etc)

The aspx page hosting the control has two controls, the reportviewer control (assembly 10.0.0.0), and a scriptmanager control

asyncrendering = 'true' and processingmode = 'remote'

So the columns are not 'always visible' with the reportviewer but they are with every other renderer that i've tried.

The report i'm testing is just a simple table with a couple groupings (built using the wizard). To enable the fixed headers I went to the groupings view and changed the "FixedData" property of the first Static member to true per instructions I found here:

So after messing around a lot I found out what the problem was.

I had set the control's height to 100%, so any overflow was technically considered "visible" to the control and the scroll bar was provided by the browser.

Fix: I set the control's dimensions so that they would not exceed the window dimensions. This causes the control to handle the overflow with its own scroll bars, allowing it to also handle frozen column and row headers.

Hi Andy,

Am also facing almost the same issue.. Could you provide me the code of the aspx page where u had used the control and done fix??

My page has a search criteria for passing values for a report and frame in which i populate the report..

Thanks Andy,

Its working now.. you are just awesome.. i ve been spending more time on this,.. Also one input is that we will have to set the property SizeToReportContent="false" in the report viewer control!!

Hi,

I am having the same issue where I can see the headers when scrolling in BIDS, Report Manager but not in the asp.net report viewer control. Can you let me know what height did you set for the reportviewer control. I have the following settings for report viewer to make headers appear while scrolling and also set FixedData = true

 <rsweb:ReportViewer ID="ReportViewer1" runat="server" ShowParameterPrompts="false"
        Width="100%" Height="550" ProcessingMode="Remote" SizeToReportContent="false"           AsyncRendering="true"> </rsweb:ReportViewer>
