The MOSS 2007 People Search Web Part (PeopleResults.aspx) navigates to an invalid URL (Returning a 404 Error)

If you get a 404 error when using the Search People Web Part, the typical problem is that the part is not pointing to the Search centre correctly.

To fix this, just do the following:
1) Modify Shared Settings on the People Search web part
2) Expand the Miscellaneous section and change the Target search results page URL to /searchcenter/Pages/peopleresults.aspx (Where the /searchcenter portion would be the URL to your search center).

Using jQuery to toggle visibility of an ASP.NET textbox based on an ASP.NET DropDownList Control

My requirement was to display/hide associated comments boxes depending on what was entered in a "yes/no/not available" style dropdown.

To implement this, I made use of the following

  1. Hooking up the click and load events of the dropdowns via jQuery so that the comments text boxes would show correctly when the page initially loaded, or when the selected value changed
  2. Putting spans around groups of controls that I wanted to hide/show to use in the jQuery selectors e.g. span with class of "pricing" for all controls that should be hidden/ shown based on the Pricing dropdown list.
  3. In the common javascript handler, passing through the dropdownlist control itself, along with the class which should be used by the jQuery selectors to be hidden/shown.

STEP 1 - Common Code (CommentFieldHelper.js) - add this as a link ref to your masterpage/base page/page/control

/*Javascript file for hide/show of Yes/No/NA controls and their asssociated comment fields*/
/* Version 0.1 - Original*/

//Initialise handlers when the control is loaded and on change to show/hide associated comment field
function initCommentFieldVisibilityHandlers(sourceControl, classToHide, areNotesShownWhenNo)
//Hook up change handler
function() {
changeCommentFieldVisibility($(this), classToHide, areNotesShownWhenNo);

//Hook up load handler
changeCommentFieldVisibility(sourceControl, classToHide, areNotesShownWhenNo)

//Set visibility of controls with the "classToHide" class defined on them (typically span class="myclassname")
function changeCommentFieldVisibility(sourceControl, classToHide, areNotesShownWhenNo) {

var selected = $('option:selected', sourceControl).text();

if (areNotesShownWhenNo == false) {
if (selected == 'No') {
$('span.' + classToHide).fadeOut();
else {
$('span.' + classToHide).fadeIn();
else {
///If areNotesShownWhenNo and selected item is not No, then hide.
if (selected != 'No') {
$('span.' + classToHide).fadeOut();
else {
$('span.' + classToHide).fadeIn();


STEP 2 - Simple inline in control/page/master page:
<script language="javascript" type="text/javascript">

//Place in your user control/page/masterpage
$(document).ready(function() {
//Initialise hide and show of associated comments textbox onload/onchange of dropdown list
$('#<%=ProposalAssessmentFormView.FindControl("FundingStateInfrastructureRelevantDropDownList").ClientID %>'),
'fundingStateInfrastructureRelevant', false);



STEP 3 - Add controls/divs/spans with the correct class tags so they will be shown/hidden based on the selected value of the dropdown list.

Warning: Declarative workflows created in SharePoint Designer 2007 will silently fail with MOSS SP1

If you have installed SP1 of WSS 3.0 or MOSS 2007, declarative workflows will not start if you log in as the system account. The fix is here:

I would at least hope for an entry in the Event Log or SharePoint Hive log files rather than a silent failure in this case!

How to Add Properties and Custom Columns to Advanced Search in MOSS 2007

One of the reasons for adding metadata (apart from supporting grouping and filtering within lists) is to enhance your search experience. However, if you cannot specify that you want to search by a particular field e.g. "Faculty", then the quality of your search results and your ability to refine searches will be dramatically reduced.

To Add a custom field to the Advanced Search, you have to do the following:
  • Go to the Advanced Search page of the Search Center itself and switch the page to edit mode
  • When in Edit mode, Modify the Advanced Search web Part
  • Expand the "Properties Node" in the Advanced Search Web Part
  • Add an element to the PropertyDefs element with your field:

  • Before this entry will appear in the drop-down menu in the Advanced Search Web Part, you’ll also have to add a PropertyRef element as a child to the ResultType element.

For more detail on how Search works for custom fields, see

SharePoint Designer 2007 Now Free! - No April Fools

Microsoft Office 2007 SharePoint Designer is a must-have tool for any SharePoint Developer. In a March 30 2009 Letter to customers, the Microsoft Office team has announced the move to make it completely free:

I originally thought the announcement may have been an April fools joke - but that is not the case... so download it and enjoy.

You can download it from here:

What I'm really hanging out for is when the generous guys at Microsoft could make the other Office 2007 products free too... :o)

We can live in hope.

LinqDatasource not updating when Update Button is clicked in ASP.NET ListView

If you are using a LINQDatasource (or any ASP.NET datasource controls with 2 way databinding) and some of your fields are not updating, then one of the first things you should check is that you are not using Eval, rather than Bind() on your templated fields.

Today, one of my colleagues had issues with both inserting and updating records using a ListView and a LINQ datasource. After a little bit of DK (Divide and Konquer), I eventually found something he had (painfully) overlooked - the Item Template values used Eval (which is fine). However, he had updated the Item template and copied it over to the Edit Item templates and Insert Item templates to save time.

Obviously, Evals are readonly - so the values were never passed into the update of the LINQ datasource.
