Apr 08, 2016, 6:16 PM
Hi Ext .Net

Currently, we have a website that uses the .Net library Ext 2.5.x , being analyzed the feasibility of migrating to version 4.0. I would like to know if there are issues with this migration ?


The website is implemented with the framework 4.0.
Visual Studio 2012
Website running on Windows Server 2003

Hello @opendat2000!

Glad to hear you are considering the upgrade to Ext.NET 4!

We believe that, being on Ext.NET 2.5 you won't have much trouble migrating but yes, several things changed from the versions. This is particularly true for graphs/charts that have severely improved thru 3.x and 4.x. Some grid panel features will also have new names.

As for direct event and C#-aspx-MVC integration, it is pretty much the same. Namespaces preserved, no renamed component handles. Some component properties have been renamed and added to follow Sencha's changes, of course.

You can have a look on Ext.NET 3 and 4 change logs (3 here (http://examples4.ext.net/#/GridPanel/Paging_and_Sorting/Page/), 4 here (http://examples4.ext.net/#/Getting_Started/Release_Documents/CHANGELOG/)) and also Sencha change logs (5 here (http://docs.sencha.com/extjs/5.0/whats_new/release_notes.html), 5.1 here (http://docs.sencha.com/extjs/5.1/whats_new/release_notes.html), 6 here (http://docs.sencha.com/extjs/6.0/whats_new/release_notes.html)) to assess more things that changed over the versions (beware that's going to be a very long reading!).

And of course, in case you decide on migrating to Ext.NET 4, we'll be here willing to help you with any possible migration troubles!

As for your system specs, they look good for Ext.NET 4. It could be a good time to consider upgrading your development tools too though. Just to catch up to new technologies and tools! It should work with Windows Server 2003 and also with VS2012.

Well, hope this helps!
