Unable to place ReportViewer Control directly inside Portlet tag

[njain]

Hi,

I am trying to use Reportviewer version 10.0 inside the Portlet tag but it gives an Javascript error. If I put it on the aspx page and then refer it works.
Does any one know if it support placing reportviewer control directly inder portlet.

<ext:Portlet ID="Portlet2" Title="RDLCompenent" runat="server" Height="450">
     <Content>
          <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt"
                  Height="240px" ProcessingMode="Remote" ShowToolBar="False" Width="320px" AsyncRendering="true">
                  <ServerReport ReportPath="/onlinereports/TestDir" />
            </rsweb:ReportViewer>
       </Content>
     </ext:Portlet>

Thanks for your help

Hi Daniil,


Microsoft JScript runtime error: '_EVENTTARGET' is null or not an object

Breaks at following code line
form._EVENTTARGET.value = eventTarget;

If I say continue on the script error; the ReportViewer control displays following error.
The ASP.net ViewState has been disabled. The Report Viewer control requires ViewState to be enabled.

What is the JavaScript error?

Hi,

Try setting DisableViewState="false" on the ResourceManger.

Example

<ext:ResourceManager runat="server" DisableViewState="false" />

Hi Geoffery,

That error is gone away; Now I am getting different error

"Microsoft JScript runtime error: 'theForm' is undefined"

on the below line in below function

var count = theForm.elements.length

function WebForm_FillFirstAvailableSlot(array, element) {
    var i;
    for (i = 0; i < array.length; i++) {
        if (!array[i]) break;
    }
    array[i] = element;
    return i;
}
var __nonMSDOMBrowser = (window.navigator.appName.toLowerCase().indexOf('explorer') == -1);
var __theFormPostData = "";
var __theFormPostCollection = new Array();
function WebForm_InitCallback() {
    var count = theForm.elements.length;
    var element;
    for (var i = 0; i < count; i++) {
        element = theForm.elements[i];
        var tagName = element.tagName.toLowerCase();
        if (tagName == "input") {
            var type = element.type;
            if ((type == "text" || type == "hidden" || type == "password" ||
                ((type == "checkbox" || type == "radio") && element.checked)) &&
                (element.id != "__EVENTVALIDATION")) {
                WebForm_InitCallbackAddField(element.name, element.value);
            }

Hi,

Try setting DisableViewState="false" on the ResourceManger.

Example

<ext:ResourceManager runat="server" DisableViewState="false" />

It appears to be not Ext.NET scripts.

Is there

<form runat="server">

on your page?
