ReportViewer Control - Height issue

This is the way I fixed, take a look

<div style="Width:auto;"> 
<form id="form1" runat="server" style="width:100%; height:100%;">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <rsweb:ReportViewer ID="rptViewer" runat="server" Width="100%" Height="100%" AsyncRendering="False" SizeToReportContent="True">
    </rsweb:ReportViewer>
</form></div>

The thing doing the magic is AsyncRendering="False" SizeToReportContent="True" the rest is basic HTML. The report will be displayed as it was designed.

There might be some code extra, but see if it works for you.

Hope it helps

this is the way i fixed it, setting the height dynamically using javascript, it works with both IE and Firefox. also works with reports larger than the maximum window size.

<rsweb:ReportViewer ID="ReportViewer1" runat="server" Width="100%" ShowBackButton="True" ProcessingMode="Remote" />

<script language="javascript" type="text/javascript">
    ResizeReport();

    function ResizeReport() {
        var viewer = document.getElementById("<%= ReportViewer1.ClientID %>");
        var htmlheight = document.documentElement.clientHeight;
        viewer.style.height = (htmlheight - 30) + "px";
    }

    window.onresize = function resize() { ResizeReport(); }
</script>
