Calling a Detail Data Form From A DataGrid Row

The idea is that we have a DataGrid which has list of records in a database table. We want to be able to select a row and call up a detail form which will have the corresponding database detail.

Getting on The Same Page With Your DataGrid

The purpose of this article is to give a succinct, understandable overview of how to setup a DataGrid so that you can page through the records of a data source. To demonstrate how this is done, I’m going to take actual code from an application I developed for a large telecommunications company. I use Visual Studio and that is reflected in this article.

The Low Down on the DropDownList Control

Whenever I see a DropDownList control, my brain says “Yes! That is a ComboBox!” That’s because I’ve been programming in Visual Basic 6.0 for too long. VB6 has something called a ComboBox. It was given that name because it could be used in different ways. That was way cool but whenever I had to write a help file or explain an application to a customer, I couldn’t use the term “ComboBox” without them wrinkling their brow and frowning at me. The “combo” aspect of the control never made sense to users, only programmers. So I started calling it a drop-down list. That made more sense to the customer. No more wrinkled brows. No more frowns. (But sometimes in the middle of the night I would quietly whisper … “ComboBox! ComboBox!”).

The RegularExpressionValidator Control and a Primer on Regular Expressions

A Vision
