Comment Feed for Channel 9 - 10-4 Episode 3: ASP.NET WebForms 4.0 http://ecn.channel9.msdn.com/o9/previewImages/100/450497_100x75.jpg Channel 9 - 10-4 Episode 3: ASP.NET WebForms 4.0 Happy New Year everyone! In this episode of 10-4 we’ll begin seeing how Visual Studio 10 and the .NET Framework 4.0 offer compelling new functionality for web developers. In this episode we’ll be specifically focusing on ASP.NET WebForms 4.0, and what enhancements it offers. We’ll be diving into the new client ID feature being introduced and see how it can be leveraged in web applications that have a high-reliance on client-centric development.   In future episodes we’ll take a deeper look at the remaining features of WebForms 4.0 including: viewstate control, data control enhancements, and routing integration. If you’d like to see something particularly emphasized, let us know, and we’ll take it into account for upcoming shows. For more 10-4 episodes, be sure to visit: http://channel9.msdn.com/shows/10-4   Over and out! en Fri, 24 May 2013 20:34:55 GMT Fri, 24 May 2013 20:34:55 GMT Rev9 Re: 10-4 Episode 3: ASP.NET WebForms 4.0 Nice explanation of the new ClientID feature!

Now that ClientID can be set, wouldn't it make just as much sense to use data binding to set its value?  ClientIDMode=Predictable is nice but has limitations as was pointed out in the video.  Setting a Suffix property is a nice shortcut if you have a data field amenable for use as a suffix, but if you don't, crafting a function that could, say, substitute spaces with dashes would also suffice.

A note about the video itself, you could have spent more time smoothing down the rough edges. Some of the monologue could have been re-recorded as it was worded a bit oddly. The transition from the end of the content to its summary was a bit jarring, too. The "3D cube" effect transition was cheesy; a simple blend or fade transition would have sufficed.

I'll make sure to kill the cheesy cube rotate as well Smiley

As far as using some type of method to create your own client IDs instead of using the predictable method, you could definitely go that route. I didn't have time to show that, but it would be pretty intuitive.

It's just an artifact of the VPC's we are using that have been "approved" and fully tested. Since Windows 7 is still very early and very young, we are wanting to have a virtual environment that performs very well and is stable enough to show off the features of the development tools themselves, not necessarily the environment they are used in.

You can rest assured that as soon as we are able to, we will be running these bits and doing these shows on Windows 7 Smiley. The Windows 7 bits are in great shape and I can't WAIT until I can start doing all of my programming on it Smiley. Soon, soon, soon Tongue Out

and see if that fixes it. I'll be updating the site to use a different xap soon, but in the meantime I'd be interested to know if the experience improves with that change (I changed VideoPlayer.xap to VideoPlayer3.xap, for those that don't want to try to parse the html and find the change).

So if you wanna use them (jQuery and Co), you must autorize the developpers to set the client ID.

I don't congratulate you. You're desining your evolutions to save your plateform and not to bring innovation or to make the developper work easy.

When you dont want to allow integration of third party products, you close your API (clientID unsetable, and client id generated), but when you realize that your are 5 years late on third party libs, you allow integration to save your plateform.

happy new year,

Would it throw an error or is it the developers responsibility to ensure that this dosen't happen.

My question is, instead of using the command argument,  will I be able to dynamically create the ClientIds to have the savedSearchId suffixed at the end.  Will I then be able to get this information out in the OnItemCommand event handler?
