    greetings, I've got a scheduler control which I'm using as an events calendar (read only). so far it's working very well, except I tried to optimize the queries using the VisibleRangeStart and VisibleRangeEnd properties of the control. The problem is that sometimes it work and sometimes it doesn't.

    I added a Response.Write() of these two values so I can track what is changing on postback.

    my page starts out with month view, and the output shows that it's reading from 3/30/2008 - 5/4/2008, which is great that's what I need. But then I click the Week view button, and the date range still shows the same range instead of the smaller week view from 4/20/2008 - 4/26/2008. If I then click to the previous week, I then SEE the date range 4/13 - 4/19, however the variables I'm outputting show that the range NOW is 4/20-4/27.

    it looks like the visible range properties are not being updated until AFTER the page posts back, so how am I supposed to properly bind to the datasource?

    I should add that I'm binding to a custom object on Page_Load, not using the datasource.

    any help is appreciated!

    Hello guys,

    The PageLoad event occurs too early to allow you to get the actual values for VisibleRangeStart and VisibleRangeEnd. You should use NavigationComplete of RadScheduler instead.
