Desktop: WinForms

A few weeks ago, the Q3 2010 release made its official appearance. This release marked the addition of various new features across all Telerik products. As with every release, we try our hardest to create video tutorials corresponding to each new product feature. In these videos we generally write the code to some sort of example application. Often we receive requests for this code, so I thought I would save you the trouble of asking and post the code to the RadControls for WinForms videos here in this blog entry. Here is a list of all videos related to RadControls ...

In the upcoming Q3 2010, we bring the extensibility of RadGridView to the next level. We will add the ability to create and replace the row type for all rows stored in the rows collection which will give our customers almost unlimited control over the customization and design of the control. The new feature gives developers the opportunity to extend the default behavior of all descends of the GridViewRowInfo class. Here is how it works: Let’s say that you want to create an expandable filter row which has extended user-friendly UI for filtering: In Q3 2010 this will be possible with a few simple...

Update (10/8/2010): With the Q2 2010 release, a few things changed in RadGridView's API. Most notably, the MasterGridViewTemplate property has been deprecated and replaced with the MasterTemplate property. Due to this, and other changes, I've decided to update this blog entry to contain the latest available information. A while back, I posted a video on Telerik TV explaining the different techniques you can use to create a hierarchical RadGridView (Please note that the video was recorded prior to Q2, so there may be a few minor differences between the RadGridView in the video and the one that is currently ...

A few weeks ago, I decided to spend some more time experimenting with the Twitter API and TweetSharp. If you missed my last blog entry about it, you can access it here. Last time I focused on creating a simple UserControl for ASP.NET that displayed recent tweets. It didn’t require any authentication and was actually quite simple to implement. This time around, I wanted to create a RadControls for WinForms based application that retrieved information about my accounts followers. This type of information is unfortunately not publically accessible through the API. You actually need to authenticate and log ...

Every once in a while, someone asks me "What’s the best way to bind 1,000,000+ records to RadGridView?” The first thought that pops into my head is, “Why in the world would you want to do that?” But – as there is always a reason for everything, good or bad, I typically go ahead and answer this question by suggesting the use of Virtual Mode. Virtual Mode allows you to implement your own data management operations for RadGridView. This means, instead of setting radGridView1.DataSource = bagillions of objects, you can intelligently manage how objects are loaded and cached ...
