Find Control inside a View of Multiview using Javascript (document.getElementById)



i am using the multiview control inside a page and i am trying to find a control using the javascript function document.getElementById. My Problem is that the function returns null cause it cannot find the control. When i open the code of the page from the browser the active view is not rendered so I think thats the reason why I am getting a null value from the function. 

On the HTML code is rendered only the first view or the view that is activated on page load.

Is there any way to find a control inside the view using javascript? or I am doing something wrong?

Thanks a lot.

Search does not find text in Word document stored in document library on a Report Center site within



We have a document library on a site created off of the Report Center site template. We uploaded a Word 2007 document with the word zebra in the text. Using the search bar at the top of the page we selected This list: Our document library and searched for zebra. We received no results.

We tested the same thing on another site (site template Team site) within the same site collection and search worked fine.

Does the Report Center search function differently then the search functionality on the Team site?

Mission Impossible? Use Javascript to Disable a Multi-Line Rich Text Field


Hey Community,

Here's a tough one that I have struggled with and so far have not been able to find an answer for - how do you use Javascript to disable a multi-line rich text field.  I have customized a SP Edit form by adding a CEWP.  In the CEWP I have added the Javascript below (only a partial code sample provided) to disable several fields in the form.  The code works fine for single line text fields but it does not work for multi-line rich text fields.  Any suggestions?

<script language="javascript">
//This runs the function when the form first loads

//This locks the fields the users should not modify
function lockFields()
  var theInputTFTitle = getTagFromIdentifierAndTitle("Input","TextField","Title");
  theInputTFTitle.readOnly = true;
  theInputTFTitle.style.color = 'gray';
  //alert(" Value: " + theInputTFTitle.value);//for testing

   var theInputDDLReplyStatus = getTagFromIdentifierAndTitle("select","DropDownChoice","Reply Status");
  theInputDDLReplyStatus.disabled = true;
  //alert(" Value: " + theInputDDLReplyStatus.value);//for testing

but I don't know what the ContentPlaceHolderID should be set to.


Really I looking for a way to easily inject javascript into SharePoint pages using Features that I can turn on and off. e.g. pieces of javascript that call jQuery functions.


Is there a way?

Javascript error on Rich Text Editor of CEWP

Hi all,

I have a problem that is really bugging and I wasn't able to find any workaround all day. I'll try to give as many details as possible:

I'm maintaining several site collections on a single server and this problem occurs only on one of the site collections. However it occurs on all subsites of this collection, it occurs on old pages and newly created pages, even on pages containing only one empty CEWP.

When I'm pressing the button for Rich Text Editor of CEWP I get the following error:

Message: Invalid argument.
Line: 5740
Char: 2
Code: 0
URI: http://www.dyrlaegeankenaevn.dk/_layouts/1030/HtmlEditor.js

I've tracked down the error with IE developer tools and I found that the error pops up in HtmlEditor.js at

function RTE2_GenerateLaunchArguments(parameterArray, webUrl, containerID)
    ............some code goes here......................

I followed containerID down the stack and it comes from:
