Change Back Color on Event Move

Most likely, the problem is that you are using EventMoveHandling="Notify". When using the Notify event handling mode the events are not reloaded from the server side unless you call DayPilotScheduler.Update() in EventMove handler.

Dan,
I do have the EventMoveHandling set to Notify. I am calling the DayPilotScheduler.Update() in the EventMove handler. Do i have to do anything else ? Or should i change the Notify to Callback ?

Vinay,

Yes, you can also change it to CallBack but it should work with Notify as well. In order to reload the events you need to set DataSource (reload the data from a database) and call DataBind() and Update(). This will ensure that BeforeEventRender is fired and the new event data set is set to the client side.

Let me know if it doesn't work as expected.

It worked i had to change DayPilotScheduler.Update() to DayPilotScheduler.Update(CallBackEventType.EventsOnly)
