we adopted the iso 8601 date format for short dates a long time ago and all our non-DNN sites use it. How do i get a DNN site to use "yyyy-mm-dd" for all ToShortDateString() items?

My http module (which works just fine on asp.net sites) seems to be overridden somewhere by DNN back to the locale short date " eg. mm/dd/yyyy" sometime after it has been set correctly.

Modify the source of every module that is used by DNN sounds extreme to me. It is also time-consuming and high maintenance. Iso 8601 is the date format stand and internationally.

I was thinking about some way of handling the Page.OnInit event so I don't need to modify the source of PageBase where this happens.

I didn't understand that as the server locale is ignored by DNN.

Anyway, for now I have added the code I need to the code-behind of the default.aspx page in the Init event handler making sure it runs after the init handler of PageBase which sets up the Culture for the current thread.

        Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init

            ' set global page settings
            InitializePage()

	<snip lots of code />

            ' ClientCallback Logic
            DotNetNuke.UI.Utilities.ClientAPI.HandleClientAPICallbackEvent(Me)

            ' My code to force short date format to iso 8601
	   Utilities.Dateformats.ForceDefaultShortDateformat()

        End Sub

This seems to work although it has the downside that I now have a non-standard dnn installation. not too hard to maintain, but I was hoping to do this via an httpModule to avoid doing this type of change.

Thanks for you comments.
