I want to perform validation of data enterred in "AddAppointment" dialog. This means, that I need to search in database and when some conflict was found, window shoudl remains opened.
When processinng it with "ActifityAdding" event, dialog is closed.
By the way, is there possibility to reopen Activity dialog from server side?
Thanks for info ...
Why not try some other event that doesn't have to do with the activity or the schedule. Use a click event for a button and load your Data needed in the click and compare it that way. And if a conflict is located tell it to return and nothing else will be preformed. If no conflict is found the activity will be added without incident. this way the dialog page stays open and can be corrected.
