(Abey George) One of my friends asked me how we can persist the checked state of DataGrid check box columns while paging. That means when a user checks one record in a page (in datagrid) and goes to the next page and selects some records there, when he returns to the previous page we need to keep th

(Alejandro Gervasio) This is the second installment of the series “Enforcing object types in PHP.” Welcome back. As you’ll surely know, this three-part series goes through the basic concepts of object type enforcement in PHP 4/PHP 5. It explores different approaches for checking types of objects to

(Tony Patton) Microsoft’s share of the office productivity suite market is no secret as Microsoft Office dominates the competition. For this reason, it is often desirable to harness the power of the Office suite when developing custom applications. After all, who wants to reinvent the wheel?

The following blocks of code will provide you with a method of iterating through all the controls on a page and performing some change on the properties of the control.

(Robert A. Nisbet) One way to refer to this wider context of data mining is to include data mining as part of the broader process of knowledge discovery (KD).

(waveangle) This solution demonstrates a simple model-view pattern for a multithreaded Windows Forms UI in .NET 2.0. I prefer to design the “model” classes for my programs first, and then design the forms around the model. This example shows a couple types of data binding techniques using worker thr

(Syed Aziz ur Rahman) A normal requirement in any ASP.Net application is to sum/average up the values in a DataGrid column to the Footer. In this article we will compare the normal methods and later create our own custom DataGrid column “SumColumn”, derived from BoundColumn to avoid repetition of th
