Problem when using AddWebPart

It seems that there is no way to dynamically add webpart in post request.

Writing something like that no going to do the job WebPart myWebPart = WebPartManager1.CreateWebPart(userControl);
WebPartManager1.AddWebPart(myWebPart, WebPartZone1, 0);

(on the next request you are not going to see the added webPart)

Why? In brief - it related to view state of the new control and page lifecycle

How to solve it?

There is a need to call SetPersonalizationDirty(); after adding the new webpart.

One problem SetPersonalizationDirty() is not a public method in webPartManager class (protected.)

So, how to solve it?

1. Create your own WebPartManager by inherit MS WebPartManager

2. Add new method as public that calls SetPersonalizationDirty

public void setDirty()
 {
   SetPersonalizationDirty();
 }

3. Replace the WebPartManager control on your page by using register tag

<@ Register TagPrefix="Mytag" Assembly="MyAssembly" Namespace="MyNamespace" %>

Have fun

Using ReSharper with Visual Studio 2005 & 2008 on the same machine

Lately I'm working with VS 2008 & VS 2005 on the same machine - no issues until now ... :)

After installing VS2008, ReSharper 3.0 didn't seem to be working - why? - because there are 2 version of ReSharper 3.0 one for 2005 and one for 2008 - there is a need to install both of them. after find out that it work also with 2008.

BTW - The 3.0 version doen't have support for c# 3.0 features.

How to register to partial-page rendering AJAX events.

While using AJAX.Net and specifically while using PageRequestManager there are several events that we can use.

• beginRequest - event the raised before any server request.
• endRequest - event that raised after the sever request end.
• pageLoaded - event after all page content is refreshed
• pageLoading - raised after endRequest but before pageLoaded.

 When we can use it?

Anytime when you want to do JS code before/after AJAX call -  

 Example: 

we just need to register to add_beginRequest and add_endRequest events and do the needed JS code there. 

<script type="text/javascript" language="javascript">
with(Sys.WebForms.PageRequestManager.getInstance()) {
add_beginRequest(onBeginRequest); //regester to the begin Request
add_endRequest(onEndRequest); // regester to the end Request
}</script>

 //JavaScript Code
function onBeginRequest(sender, args) {
try
{
var win = $get("mainTable");var winBounds = Sys.UI.DomElement.getBounds(win);
var x = Math.round (winBounds.width /2) ;
var y = Math.round(winBounds.height / 2);
Sys.UI.DomElement.setLocation($get("loader"),x,y);
$get("LoadingIcon").style.top = winBounds.y;$get("LoadingIcon").style.left = winBounds.x;
$get("LoadingIcon").style.width = winBounds.width ;
$get("LoadingIcon").style.height = winBounds.height;$get("LoadingIcon").style.display = '';
}
catch (e){}
}

AJAX Debugging

I'm sure you know about the JavaScript debugger command that enable you to open a JavaScript debugger whenever you wrote it on your code .

But Are you familiar with AJAX Debug class - the Sys.Debug?

The simple method is Sys.Debug.trace(message) - the trace method will show the trace message on VS console window, and will look for Html control with TraceConsole id : <textarea id="TraceConsole"></textarea> on the page, if there is it will add the trace message there.

Sys.Debug.assert(condition, message, displayCaller) - the assert method, will show a message in case the condition is false, and asked if you would like to debug the code.
The displayCaller (bool parameter) - To show or not the function name that call assert method, as part of the debug message

C# 3.0 Anonymous Types - Are we going back to JS?

In my previous post I've talked about new feature in C# 3.0 - Extension Methods and while cont' playing with Framework 3.5, I notice a new keyword - var, What is var? I know var from JavaScript, what it's doing in C#? :)

So, var in C# is object initializer means it specifies the values from one or more fields and properties of an object.

For Example: 

var Employe = new {First_Name = "Kuku", Last_Name = "The King", Age = 89};

The compiler will create an anonymous type at complie time that will be somthing like that:

class __AnonymousTypes
{
   private string last_Name;
   private string first_Name;
   private int age
   public string Last_Name{ get { return last_Name;} set { last_Name= value ; } }
   public string First_Name{ get { return first_Name;} set { first_Name= value ; } }
   public int Age{ get { return age} set { age= value ; } }
}
__AnonymousTypes p1 = new __AnonymousTypes();
Employe.First_Name = "Kuku";
Employe.Last_Name = "The King";
Employe. Age = 89;

 
Well, I don't see a massive usage with the feature. (I didn't want to say any :))

Cheers.
