Animation Control , Adding Cool Animations in your application, Scenario 2

Assigning Animations to Client-Side Controls

If you need to assign Animation Behaviour  to any Client-Side Controls using the AjaxControlToolKit's Animation Extender Control ,

you gotta Explicitly create the AnimationExtender Control on the Client side using the $create function

$create's Documentation is here   Sys.UI.Component $create Method.

$create(type, properties, events, references, element);
Whenever, you add an Animation Extender control using the steps mentioned in my previous Post,

 Animation Control , Adding Cool Animations in your application ,

For the Markup

<!-- asp:Image Control that houses the ThumbNail --> 
<asp:Image runat="server" ID="imgThumbNail1" 
     ImageUrl="thumbNails/Second_Dimension_by_celsojunior.jpg" />
<cc1:AnimationExtender ID="animationExtendThumbNail1" runat="server" TargetControlID="imgThumbNail1">
              <Move Duration=".2"  horizontal="800" vertical="600" Unit="px"  />

The Runtime generates the Following  $create Function

<script type="text/javascript">

<!-- Called when the Client Side Script Framework
    and Controls are Initialised--> 
Sys.Application.add_init(function() {
         <!-- The ID to be associated with the control--> 
        <!-- The Control to be targeted imgThumbNail1--> 
         null, null, $get("imgThumbNail1"));
Looking at this , we understand that the Server-Side Control associated with the Animation Control is Specified as the 
   last parameter of the $create function is the Element the behaviour has to be associated with .
So , lets start by creating a client Side Control .
1) Create an <img> tag on the client Side , using the document.CreateElement Method
Function Name : CreateClientSideElementAndAttachAnimation
Parameters    : 
               a) parentElementId : The Parent Element Which will house the Dynamically Created Control .
Purpose       : This Function Creates A client Side <img> tag and Calls the Function to attach the Animation behavior
//parentElementId is the ID of the HTML element that will house the Dynamically Created Client Side Control 
function  CreateClientSideElementAndAttachAnimation(parentElementId)
   //Lets be Efficient and use StringBuilder 🙂
   var imgElementTagString = new Sys.StringBuilder("");
   // The ID of the dynamically Created control
   var imgElementID = "imgDynamicControl"
        imgElementTagString.append(" id=\""+imgElementID+"\" ");
        //Style the Control to have the "Position" Attribute set to "Absolute" and assign the left and Top Positions of the control 
        imgElementTagString.append(" style=\"position:absolute;top:100px;left:20px;\" ");
        imgElementTagString.append(" src=\"thumbNails/Second_Dimension_by_celsojunior.jpg\" ");
   //Create the Img Tag using the document.createElement
   var imgElement = document.createElement( imgElementTagString.toString() );
   //Add the Child to the "ChildNodes" collection of the Parent Control 
   $get(parentElementId).appendChild( imgElement );
   //Attach the Animation Control to the Dynamically Created Image Element
   AttachAnimation( imgElementID );
2) Attach the Animation to the Dynamically Created Control 
Function Name : AttachAnimation
Parameters    : 
               a) controlID :  The Dynamically Created Control that has to be associated with the Animation Extender
Purpose       : This Function Creates an Animation Extender on the Client Side and Associates the Behaviour with the Dynamically 
                Created Control Side
function AttachAnimation( controlID )
    //The Id of the Dynamically Created Animation Extender Control 
    var animatorID = "dynamicallyCreatedAnimationExtender";
    //Dynamically Create the  Animation Extender Control 
    //The Animation associted with the Extender in JSON 
    // Associate the Client-Side Control with the Animation Extender by  using  "$get(<controlID>")
     null, null, $get(controlID) );
The Script might look a little convoluted , but once you get the hang of it, its pretty easy to tweak it as necessary .

    Why would I get a javascript error stating "’AjaxControlToolkit’ is undefined"?

    Hey, Wondering whether you could list the function definitions for the javascript usage Im searching the ScriptResources for them, can’t find them anywhere else,

    Like this:

            var resizeAnimation = new AjaxControlToolkit.Animation.ResizeAnimation($get("InfoFormIframe") , 0.2 , 45 , 100 , 100 , "%");

  5. Hi Nathan,

    Did you check out this link ?

    It contains the download location for all the animation examples
