MS Tech Ed 2011 Coming Soon

Microsoft Tech ed 2010 was a great success.
Infact Most of such conferences always provide a great place to meet other technology enthusiasts and ofcourse,whats in the pipeline for future products of a company or field..

And yet again,MS Tech ed India is coming on 23-25 march in Banglore,India.Well,the place is ofcourse right suited for any IT/Computing conference.After all,Its Silicon Valley of India..

From Last year.I remember a session by Harish about “Building pure client side apps with Jquery and Microsoft Ajax .”

Here’s the video:

http://live.viasilverlight.com/TechEdOnDemand/Breakouts/TheWebSimplified1/Session4/AjaxClientSideApps.wmv

At that time only,I got to know that jquery is so easy to use for ajax or client side templating.Though I prefer jquery over Microsoft Ajax many folds.UpdatePanel is Dead for sure in my view.
I believe,Web forms will be dead sooner or later with ASP.Net MVC gaining share many folds.(TODO:Learn MVC).

The new standard is surely:JQUERY .

Between,Last years videos and ppt’s are available to browse and download:

After going through Tech Ad 2011 session agendas : http://www.microsoft.com/india/teched2011/agenda.aspx

Few of my personal choices to watch would be:

Day 1: a) Identity And Access Control in the Cloud
b)Windows 7 at Home:Digitizing your Home.(Sounds cool.)
c) And ofcourse,Jquery and MS ajax(Lets see if MS can do something that’s not already happening with their version Of Ajax)..

Day 2: a) Lap Around Silverlight 5 and Html 5 as I have heard some hot talks that html5 will kill Silverlight,(I don’t see it in near future though).

b) Html 5 more than “Html 5”…Google will be seeing this one.

Day3: a) Cross Browser applications in Azure
b)VS 2010 sessions of automated testing azure apps etc.

Windows Phone 7 sessions will surely be of more interest now after MS-Nokia Deal.

Though,Personally,I would want atleast some worth of sessions on MS future in Robotics,AI.Perhaps I am looking at wrong place..(When is PDC?)

And Since,Bill Gates consider Robotics as the next big thing,

Refer this one : http://www.cs.virginia.edu/robins/A_Robot_in_Every_Home.pdf

I am sure,they wont loose this new hot spot to competitors, like how google rules in Online Search now.Robotics and AI will surely provide a big battlefield for future.See,What IBM is doing with IBM Watson.

OR see this, http://www.sciencedaily.com/releases/2011/02/110218083711.htm

this is cool only if you can control your mind.Atleast,I’ll prefer regular driving (I would devote my mind seeing people,places which we see on road).thats what jouney makes “cool”.:P.

Adding controls dynamically in ASP.Net?

sonam — Mon, 05 Oct 2009 10:58:14 GMT

The Problem scenario is like this:

I have a button and a textbox on a asp.net page:

<asp:Panel ID="Panel1" runat="server"

<asp:TextBox ID="GroupName" runat="server" Width="352px” />

<asp:Button ID="CreateGroup" runat="server" Text="Create"

onclick="CreateGroup_Click" />

</asp:Panel>

<asp:PlaceHolder ID="PlaceHolder1" runat="server" />

When I click the button a label should be added dynamically to the placeholder located in the page:

The code in click event handler is as:

protected void CreateGroup_Click(object sender, EventArgs e)

{

Label label = new Label();

label.Text = GroupName.Text;

label.ID = GroupName.Text;

PlaceHolder1.Controls.Add(label);

}

Its working but the problem is only last label are added to placeholder not the previous ones like:

If I put “Computer” in texbox and click,then the label is added .fine.

But If I put again “science” and click,then the label with “science” is added but the previous label is not rendered.

Any guesses,solutions?

Well..here are some workarounds:

You can use this:SEE THE EXPLANATION WHY ITS HAPPENING:

Or this:

http://stackoverflow.com/questions/113392/dynamically-added-controls-in-asp-net

http://www.4guysfromrolla.com/articles/092904-1.aspx

Or the best solution is

Avoid dynamically creating controls.Actually creating controls dynamically is not the problem but maintaining there state might be.

Instead of storing dynamically added controls in ViewState,

You can use a collection to store them and store it in ViewState[Updated] . But I would again say,Avoid such things as much as possible..

If you get any better workaround ,Please do point me to that.

In my opinion,The best Solution will be the solution which will add the controls just like they are added at design time.But design time is different than runtime..Which occurs after compilation.

Please read the second comments that follows this post(Some nice cons of static variables in ASP.Net pages).

I am pasting here as i really liked the "Disadvantages of static variables in ASP.NET"

"You can use a collection to store them and declare it as static" I need to caution against this. I have learned some hard lessons with this.

I have many developers use static variables in their ASP.NET pages and NOT realize thast every user shares that variable.

If I have static array of strings that a button click adds to, and I have 2 users click that button, there will be 1 array 2 items in that array. A page where this is the intended affect desireable is rare.. and probally badly designed :).

The implications of adding a Control as a static member would be much, much worse. (GC collection and a threading nightmare!)

Storing Meta data using a client-specific storage, like Viewstate may be the way to go.
