Replacing URL in HTML using JQuery

Scenario:
Sometimes if a list is currupted, Allitems.aspx's HTML starts acting weird and we dont want to spend too much time to dig deep into the problem but want a quick fix and endup fixing the HTML. Same goes here.

Solution:
Following code change the URLs in a page to a predefined URL.

<script type="text/javascript">

 if(typeof jQuery=="undefined")
 {
  var jQsrc="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.4.min.js";
  document.write(unescape("%3Cscript src='"+jQsrc+"' type='text/javascript'%3E%3C/script%3E"));
 }
</script>

<script type="text/javascript">

$(document).ready(function() {
  //find all hyperlinks in the table holding calendar links and
  //change them to point at the display page instead of the edit page
  $("table[id^='CalViewTable']").find("a[href*='OldForm.aspx']").each(function(){
  var originalUrl = $(this).attr("href");
  var newUrl = originalUrl.replace("OldForm.aspx", "NewForm.aspx");
$(this).attr("href", newUrl);
});
});

</script>

SharePoint Client Object Model vs Server Object Model Classes

One of the new feature of SharePoint 2010 is the Client Object Model. By using Client Object Model, developers can build the applications which can talk to SharePoint without using WebServices and without deploying any server side code.

Following is the list of Client Object Model classes and their equivalent to Server Object Model classes:

Client Object Model	Server Object Model
ClientContext	SPContext
Site	SPSite
Web	SPWeb
List	SPList
ListItem	SPListItem
Field	SPField

Example:

using Microsoft.SharePoint.Client;

private void SomeMethod()
{
  ClientContext clientContext = new ClientContext(siteUrl);
  Site siteCollection = clientContext.Site;
  Web site = clientContext.Web;
}

EMail as Primary Key in List

Problem:
I have been asked a question today from one of the developers in another team that he wants to create a user registration list where emial should be unique for every user. And if user add item with existing email then he should be informed.

Solution:
We know that this functionality does not exist in the OTB SharePoint list features. After googling a bit I found following excellent solution using JQuery:

Silverlight Application in SharePoint 2010

In my last post I have explained how to develop the Silverlight application using Visual Studio 2010. Then we deployed that application in SharePoint 2007 using Content Editor Webpart. In this post I will explain how to deploy the same application in SharePoint 2010 using Silverlight Webpart.

Note: Please click here for the Silverlight application development using Visual Studio 2010. This Hello World Silverlight application can be deployed on both SharePoint 2007 and 2010.

Deployment to SharePoint 2010

3. Create a sample webpart page.


4. Open the page in Edit mode and from the ribbon select Editing Tools -> Insert -> Web Part.


5. From categories select Media and Content -> Silverlight Web Part -> Add.



6. Provide the URL of the SilverlightApp.xap file and hit OK.



7. It should look like this
