Populate the fields based on Drop Down selection in NewForm.aspx using JQuery

Before doing that add the JQuery.js and SPServices.js reference in the Master Page. 

Then add the following script in the NewForm.aspx of the List 

<script type="text/javascript">

$(document).ready(function(){

        

         $().SPServices.SPDisplayRelatedInfo({

         columnName: "Project",

         displayFormat: "list",

         headerCSSClass: "ms-hidden",

        rowCSSClass:"ms-hidden",

Script to Disable the Fields in NewForm EditForm in SharePoint

Before adding the following script to the NewForm or EditForm we have to give the Reference of jQuery.js and SPServices.js either in Master Page or in the form where you what to add this script.

<script language="javascript" type="text/javascript">

  $(document).ready(function() {

Reference CSS and JS files for Ribbon In SharePoint 2010

One of the most common things that you might be doing when creating your custom ribbon controls is to define JavaScript for the handlers that will be executed upon your controls being clicked.

One of the most demonstrated examples of how you can define your own JavaScript is

 <CommandUIHandlers>

        <CommandUIHandler

         Command="Demo_HelloWorld"

         CommandAction="javascript:spSticky();"     />

  </CommandUIHandlers>

In here, the highlighted  part is my command spSticky(). The CommandUIHandler  though doesn't allow to define external file where all of our scripts will be hosted. This might be puzzling at first and you may think that you need to define all of your JavaScript right inside the elements file – which obviously makes it hard to maintain your JS code in a future.

Well, the good news is that you can reference JavaScript external file for your handlers; you will still call your handler function just like in the example from above but here is what you add in your Elements (ribbon definition) file:

<CustomAction

   Id="OwnersButton.Script"

   Location="ScriptLink"

   ScriptSrc ="~site/_layouts/Images/Scripts/js/Custom.js"/>

If your custom.js has the reference of jquery plugin, then give the reference which should be below your custom.js else it will not take the reference of jquery.

  <CustomAction

   Id="OwnersButton.Script"

   Location="ScriptLink"

   ScriptSrc ="~site/_layouts/Images/Scripts/js/jquery-1.8.2.js"/>

If you want the give the reference of the CSS in the Custom Actions, the below script has to be added in the Custom Action.

  <CustomAction

   Id="OwnersButton.Script"

    Location="ScriptLink"

    ScriptBlock="

      document.write('&lt;link  type=&quot;text/css&quot; rel=&quot;stylesheet&quot; href=&quot;~site/_layouts/Images/Scripts/css/jquery-ui-1.8.21.custom.css&quot;&gt;&lt;/' + 'link &gt;');"

     />

Checking Whether an Item Is in a Set

We often need to know whether an item is already in a set.
public bool IsDocumentSetItem(SPListItem itemToCheck)
{
bool documentSetItem = false;
if (itemToCheck.File != null)
{
DocumentSet documentSet;
documentSet = DocumentSet.GetDocumentSet(itemToCheck.File.ParentFolder);
if (null != documentSet)
{
documentSetItem = true;
}
}
return documentSetItem;
}
The code asks the current item to return the containing set. If there is no set, then the item is not part of any document set.
