Hi Adam,

 

The application is an intranet app and developing a small test app so that you can diagnose the problem is outside of scope at this stage.

 

Using the UseStandardDialog="true" does fix the issue for people using single monitors.  On my development machine it opens the popup in the middle of the primary monitor.  It will probably be a good enough work for the purposes of our intranet application.

 

My real question was actually what properties/attributes/classes can I use to control the opening position of the dialog boxes.  Have you got a link to this part of the documentation?  It would be useful to have an Xpos/Ypos or at least alignment setting.

 

It looks like by default the dialog is using the middle of the page as the opening location.  In long pages this means it can open below the level of the browser leaving the user with a modal dialog they can't see and a page that appears disabled.  Some users will scroll down and locate the dialog others will give up. 

 

Cheers,

Peter
