    This is the solution to fix it, setting the height dynamically using javascript, it works with both IE and Firefox.

    <script type="text/javascript">
var ReportViewerForMvc = ReportViewerForMvc || (new function () {

    var _iframeId = {};

    var resizeIframe = function (msg) {
        var height = 360;//here you specify the height if you want to put in 
                        // percent specify value in string like "100%"
        var width = 1255;// follow above

        $(ReportViewerForMvc.getIframeId()).height(height);
        $(ReportViewerForMvc.getIframeId()).width(width);
    }

    var addEvent = function (element, eventName, eventHandler) {
        if (element.addEventListener) {
            element.addEventListener(eventName, eventHandler);
        } else if (element.attachEvent) {
            element.attachEvent('on' + eventName, eventHandler);
        }
    }

    this.setIframeId = function (value) {
        _iframeId = '#' + value;
    };

    this.getIframeId = function () {
        return _iframeId;
    };

    this.setAutoSize = function () {
        addEvent(window, 'message', resizeIframe);
    }

}());

ReportViewerForMvc.setAutoSize();
</script>

    • Please don't change the following code of ".aspx"

    <asp:ScriptManager ID="ScriptManager1" runat="server">
 <Scripts>
  <asp:ScriptReference  Assembly="ReportViewerForMvc"          Name="ReportViewerForMvc.Scripts.PostMessage.js" />
   </Scripts>
</asp:ScriptManager>

    Here we are replacing the ReportViewerForMvc.Scripts.PostMessage.js explicitly with our own resizeIframe where we specifying width

    I recently sat down and fought the ReportViewer control to expand to the height of the report content while still allowing .AsyncRendering = true. Here's what I did, which requires jQuery, and has only been tested with Report Viewer 2008 (9.0.0.0).

    <script type="text/javascript">

    $(function() {

        $('#<%= uxReportViewer.ClientID %> > iframe:eq(0)').bind('load', function() {
            ReportViewerResize(this);
        });

    });

    function ReportViewerResize(frame) {
        var container = $('#<%= uxReportViewer.ClientID %>');
        try {
            var reportFrame = $(frame).contents().find('html')[0].document.frames["report"].document;
            var reportHeight = $('div#oReportDiv > table > tbody > tr > td#oReportCell', reportFrame).height();
            $(container).css({ height: '' + (reportHeight + 10) + 'px' });
        } catch (e) { }
    }

</script>

    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>

    This is an issue with XHTML 1.1 standard. Change your page doctype to transitional to get 100% height working:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/>

    Or if you still struggle, remove it completely.

    The following options will fix your SSRS Report loading problem in ASP.NET page.

    And there is a fantastic property called ZoomMode="PageWidth" that will fix your report into full page. you also can use ZoomMode="FullPage" or ZoomMode="Percent". All those property will fix your page loading issue in ASP.NET page.

    <rsweb:ReportViewer ID="ReportViewer1" runat="server" Height="100%" Width="100%" ZoomMode="Percent"></rsweb:ReportViewer>

    As to what I have experienced, the report viewer control renders by default with a height of 400px if SizeToReportContent is set to false.
    If you want a dynamic height, you need to add a css class to the report viewer and the following css:

    #reportViewerContainer > span
{
    display:block;
    height:100% !important;
}

.reportViewer
{
    height:100% !important;
}

    "reportViewerContainer" is the parent container of the report viewer (a div, body etc.). The viewer renders as a span with height: 0 and inside is all the content. If you change this, everything should work fine.
