    Performance Tip: Use Web Service Load On Demand with RadTreeView

    A common scenario for a treeview control is to populate it with lots of nodes. Adding a few thousand nodes initially is not a good idea though. Think of all the rendered HTML. Even rendering a few thousand strings (without any extra markup) will result in a few megabytes of HTML. That's where load on demand comes into play. RadTreeView supports three different types of load on demand: web service, server side callback and server side postback. From those the server-side postback mode is least efficient in terms of performance because it postbacks and updates the whole page. Here is how...

    RadTips, Episode 2: Client-Side Paging in the RadGrid

    Here for your viewing pleasure is the second episode in my new series, RadTips. In this episode I show you how to implement paging in the RadGrid when binding data to the grid on the client.

    Working with RadScheduler recurring appointments on SQL server*

    UPDATED: Rebuilt project with the 2011 Q2 version of RadScheduler You might have noticed that RadScheduler uses very cryptic strings to describe repeating appointments. We have decided not to reinvent the wheel and in fact this format is closely based on the iCalendar (RFC2445) standard. Here is an example: DTSTART:20080218T000000Z DTEND:20080219T000000Z RRULE:FREQ=MONTHLY;INTERVAL=12;BYDAY=-2MO;COUNT=3;   This rule says: "The event starts at midnight on 18th of February 2008, lasts one day and repeats each year, for 3 years, on the second to last Monday of February".
