Telerik’s OpenAccess ORM is no exception. With the Q3 release of OpenAccess next week, OpenAccess will have full support for SQL Azure, going further than the basic support available today that I demonstrated on my blog last month. Full wizard support, forward and reverse mapping, and of course data services support via the Telerik Data Services Wizard. Let’s take a look at the basics here. Getting Started To get up and running and show the mapping and LINQ support, I will open Visual Studio 2008 (or 2010) and create a simple Console...

In some scenarios it is required to load thousands of items in a ComboBox. Since by default the control creates RadComboBoxItem containers for each data item, it might take some time to open the drop-down. To resolve the problem you only need to change the RadComboBox ItemsPanel with VirtualizingStackPanel: <telerikInput:RadComboBox> <telerikInput:RadComboBox.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel /> </ItemsPanelTemplate> </telerikInput:RadComboBox.ItemsPanel> </telerikInput:RadComboBox> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   thus making the drop-down to open instantly. Attached is a simple application that loads 1000 items in two RadComboBox controls, one virtualized, the other – not virtualized. The difference between the two controls is visible and becomes much larger if you create 100,000 items! VirtualizingComboBox I hope this helps....

Did you hear the bells and whistles which accompanied the public Q3 2009 Beta release of RadControls for ASP.NET AJAX? If not, I think it is time to explore it and get acquainted with the new controls/features that we will be introducing for the official Q3 2009 release expected in the first week of November. One of the new controls that I encourage you to play with is RadListView for ASP.NET AJAX. If you allow me to quote one of our clients who already gave the Q3 2009 Beta a spin, it is "something like a rotator on steroids" which allows you...

With the next Q3 2009 official release we are introducing a significant improvement to the validation mechanism of the RadGridView control. If we compare the new validation to the previous versions we add another validation layer (Data Layer) and refactoring of the related events. In a series of blog posts I’ll try to clarify this mechanism with several small examples. I’ll start the series with validation for a single cell.   How to: Validate data on a cell (property) level with RadGridView for Silverlight and WPF   The cell validation occurs when a GridViewCell is edited and its new data is about to be committed. At...

Whenever Telerik puts something up on Telerik Labs we hope that some early adopters will try it out and give us feedback. We had an amazing demand for the Telerik OpenAccess WCF wizard and got tons of feedback. The most overwhelming piece of feedback is the name of the wizard: so as of this CTP, the wizard is now renamed the Telerik Data Services Wizard. We made some key enhancements in this build for usability. The big thing is that you no longer have to...
