We have a solution hacing couple of ASCXes that uses Ajax Control Toolkit (Modal Popup, Calendar, Collapsible Panels etc); I am trying to wrap them as DNN module for a client who is using DNN 6.2. In my dev setup; I have installed DNN 6.2.9 having Telerik Web UI 2012.2.724.35 to be exact; I have tried different Ajax Control Toolkit NUGET packages and these three (DNN, Telerik and ACT / Ajax Control Toolkit) are not playing nice together.

We need to deploy to IIS6 / SQL 2005 server; so have to keep things in DNN 6.2 / .NET 4. Can anyone confirm if its possible to use ACT for DNN 6.2 module development? If yes; which can anyone point which version of ACT is recommended?

Note: there is a core hack you can do which apparently works -see http://www.dnnsoftware.com/forums/for... -note: I haven't tested this and don't know anyone who's used it so can't vouch for it working.

no, I'm afraid not - it's not something we get often asked about and due to it's history not something we've looked to fix. To give some background -DNN started to use asp.net Ajax as soon as it came out, and later added telerik to the distribution (both of these work seamlessly together as telerik inherits from the MS Ajax scriptmanager class). For the first few years of telerik, ACT worked fine until Microsoft decided to break binary compatibility and change inheritance from scriptmanager (which other Ajax frameworks such as telerik or component one used) to a brand new class called toolkitmanager (which only ACT uses). This meant that lots of code broke (you can see some of the complaints at https://ajaxcontroltoolkit.codeplex.c... ). Frankly after that point lots of people stopped trusting ACT (i.e. if Microsoft can arbitrarily change something and break lots of existing websites it wasn't something wise to trust), and most people tended to use telerik in a DNN environment - until the past few years when the usage of jquery plugins became popular.
