    How to load 1M+ records in Telerik’s ASP.NET Grid without Compromising Performance

    The latest release of Telerik’s ASP.NET AJAX controls (Q3 2013) shipped the so famous virtualization feature in our almighty ASP.NET DataGrid allowing you to load hundreds of thousands of records without compromising performance. Another goal for this functionality was to replace the previous Virtual Scrolling and Paging features which were a great example but did not deliver the full user experience that a virtualization mechanism could deliver.

What is virtualization? To put it simply, when you bind RadGridView to a DataTable with 1000 rows, you get 1000 data row objects created in RadGridView (of type GridViewDataRowInfo). However, not all data row objects can be visible at the same time in the RadGridView estate in your application. This is why only the visual rows that can be shown in the estate get created (these visual rows are of type GridDataRowElement), or about...

    GridView in ComboBox with RadControls for Silverlight

    Recently we received several requests for an example, demonstrating how to put a virtualized GridView in a ComboBox popup. The best way to do this in my opinion is to replace the ItemsPresenter of the ComboBox with a GridView. There is some plumbing that has to be done, but I managed to separate it in two attached behaviors. The original idea is described in my blog post for TreeView in ComboBox which I recently updated with the latest control template of RadComboBox for Silverlight. The principle is exactly the same with RadGridView and it should work with very minor adjustments with...
