Allowing Users to Upload Multiple Files at Once

This article demonstrates how to allow users to upload multiple files from thier computer (the client) to your server. Specifically, this article will demonstrate how to set up a page that has 5 HtmlInputFile controls where a user can choose 5 images to upload. Only .jpg and .gif extensions will be accepted on the server and each one will be saved to a different directory::so any image that has the extension .jpg will be saved to the jpgs direcory and .gif will be saved to the gifs directory and everything else isn't saved at all.

ASP.NET DataGrid Paging Part 2 - Custom Paging

While 100 percent backward compatible with ASP.NET 1.1, ASP.NET 2.0 brings a number of internal changes to ASP.NET. These include changes to the code model, compilation, page lifecycle, and more. This article outlines those changes.

ASP.NET Server Control Creation

C#Today

ASP.NET custom server controls provide a powerful architecture for isolating the atomic functionality of applications, using highly reusable compiled components (dll). This makes enforcing application-wide rules and applying composite view design patterns easy. In this article, Daniel Cazzulino will look at numerous facets of these controls, such as extending their functionality.

Building a DataNavigator Control

Building a Full-Featured Custom DataGrid Control

The list of ASP.NET rich data-bound controls is a long one, but it's not all-encompassing. You won't find any Microsoft® .NET counterpart for the Data control—a scrollable and updateable binding context that data-bound controls could rely on to refresh their user interface. The original Data control allowed for simple movements—first, next, previous, and last. It worked on top of a Recordset object and exposed the UpdateRecord method to save changes according to the capabilities of the currently selected type of cursor. While not the perfect programming tool, the Data control was especially good at building simple user interfaces for tables used internally for administrative purposes.

Building a Generic Database Tool Using .NET and Three Tier Architecture

In this article, we will examine and implement these very features and demonstrate how you can build your very own Datagrid control component, one that you will be able to customize, and more importantly reuse. Based on this ability, you will then end up with one powerful control that will have many implementations, from which you could learn about creating almost any other types of custom controls.

Building a Variety of Custom Controls Based on the DataGrid Control

In this article, Sun shows how easy it is to develop a n–tiered Web application to create a generic database tool using ASP.NET and the .NET Framework. The system is quite simple and is able to handle the management of any simple table in any database. It provides an excellent starting point for providing a generic database tool.

Building Windows Forms on-the-fly with XML and C#

The DataGrid Web control is by far the most powerful and versatile of all ASP .NET controls. Not only does it have many properties that you can set programmatically, but it lends itself to more advanced forms of customization. In this column, I'll build a few flavors of DataGrid-based Web controls. In doing so, I'll review the major design issues that characterize these controls and answer some of the questions most frequently raised by readers after they tackled the series of DataGrid columns in the March through June 2001 installments of Cutting Edge. In particular, you'll see how to add a custom toolbar to a DataGrid control to accomplish common tasks such as New and Unselect.

C#Today

In this article, Ashiwn Kamanna takes the concept of an XML driven Form builder a step further than the basics as he discusses how to eliminate the requirement for Form development, not only in an ASP based web application, but also in any potential client of an application. He discusses how to build a Form dynamically in a C# based windows application, and also discusses some object oriented patterns as he walks us through an example.
