Design Internship Program
http://internship.dreamture.net is the new blog of this summer's design intern at the UX department here in telerik, where Dimitar Raykov will regularly upload his ongoing work on the weekly internship assignments. Following a successful attempt to accommodate an intern a couple of years ago, this summer we wanted to expand the effort with a program that gives not just a preview of an actual work environment, but also has a more academic side to it with a chance to experiment within the design practice. Before I laid out the program I did some research on existing programs elsewhere but failed to find... -

How To: RadGrid hierarchy from objects hierarchy
Every once in a while we receive support about how to create hierarchical grid directly from objects hierarchy and I decided to post small example how to achieve this easily: protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e) { RadGrid1.DataSource = MyList; } protected void RadGrid1_DetailTableDataBind(object source, GridDetailTableDataBindEventArgs e) { e.DetailTableView.DataSource = MyList.Find( delegate(Master master) { return master.ID == Convert.ToInt32(e.DetailTableView.ParentItem.GetDataKeyValue("ID")); ... -

RadTreeView for ASP.NET Ajax Load On Demand Modes - why so many?
In my previous blog post I told you how the Web Service load on demand mode of RadTreeView delivers the best performance. A logical question arises - why we have the other load on demand modes (server side postback and callback) if they do not perform on par with the Web Service mode. The answer is not that obvious. The truth is every load on demand mode has its pros and cons. The following table describes visually the load on demand modes according to three criterions - performance, templates support, ease of... -

Best Practices: Client-Side DataBinding with the RadGrid for ASP.NET AJAX
I recently released the first two episodes of my new screencast series, RadTips. In these episodes I show users how to take advantage of the new client-side databinding feature of the RadGrid (only available in the Q2 2008 release of RadControls for ASP.NET). I wanted to highlight what we consider to be a best practice when using the RadGrid's client-side API to do your databinding, something I didn't do in either of the episodes. While client-side databinding can save some bandwidth and improve round-trip speeds on subsequent requests, it is actually faster to to bind data to the RadGrid on the... -

I'm back again, what comes next?
Yeah, I know, it's been quite some time since my last post. The ideas keep coming though and I’ve just realized there is no better time for a QA to blog than ... the summer. Do you know why? Well, just because of the summer time! You know, devs are humans too and they also need to rest a bit. ;) I can at least stop bugging around for a while and post some nice, interesting content. I'm afraid the list of ideas for my future posts is already quite long. However, since I'd like to share the most fascinating ...August 07, 2008 2 min read -

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...
