As we know an input file element allow you to select only one file at a time i.e. you can upload one file at a time using one input file element. If you want to upload multiple files at a time, then you have to add as many file input elements as the no of files you want to upload. The reason behind this you can only store the file upload information in an input file element. You can not set value directly for an input file element programmatically due to security reasons. Now I am going to prese...

Implementing GridView rows navigation using the arrow (Up/Down) keys is an easy task in IE but some tricky in the other web browsers. Initially when I wrote the JavaScript code for it, script was working well in IE but not in the other browsers. After making lots of R’N’D on internet, I have learned some tricks from the Mozilla Development Center web site [^] in order to run this script on the other web browsers. Using this script you can navigate GridView rows with the help of the arrow (Up/Dow...

It's a very common requirement to have login functionality in almost every Web application. Before ASP.NET 2.0 was released, we used to design user interfaces (UI) for authenticating the user. This involved writing a lot of redundant code. To avoid this, ASP.NET 2.0 provides a complete login solution in the form of a bunch of server controls for Web applications that require no programming. Internally, these controls are responsible for rendering the appropriate UI where a user can enter his or ...

The DynamicImage control derives from the DynamicImageBase which is in turn derived from Image. This control acquires image bytes from varied sources and renders them to image capable devices using an internal normalization process. It stores the images in the System.Drawing.Image object and is cached in ASP.NET Cache with a randomly generated key....

This article describes a control which can host a UserControl. It allows to Ajaxify a user control without any code change. The main benefit is that when refreshing its content, it does not instantiate the full page but only the contained user control. Most of the ASP.NET features (at least the ones that I tested) are supported: viewstate, controlstate, postback events, validators... Moreover, one of the cool features of this control is allowing UserControl to do cross-domain Ajax postback....

Developing some web site we often should use some control in the GridView control. In this case we have to create the GridView control with TemplateField columns and use some special methods to access needed data. Inside the GridView control we can use both standard server controls (such as DropDownList , etc.) and our own controls. In this article I will show how a web user control can be used in the GridView control. As example we will use our old friend : the ListBoxesFT_C control....

Portal applications are very popular today and the better ones share some common traits. Useful portals serve up generous portions of content through a user interface that is modular, consistent, and easy to navigate. More sophisticated portals go even further and allow site members to contribute content, upload documents, and personalize portal pages. Microsoft added a scalable portal framework to the Windows Server™ 2003 platform with the release of Windows® SharePoint® Services, which provide...

With ASP.NET 2.0, you can add authentication, authorization, and profiles to your Web site without writing a single line of code. That's quite a step forward from the way things used to be. Like most of the new features in ASP.NET 2.0, authentication, authorization, and profiles each have their own built-in providers. You can think of providers as modules that contain the methods for a particular task. These providers are quite flexible-they can be customized by specifying attributes that pass i...

This month marks the 11th anniversary of my column and the inauguration of a new title: C++ At Work. We're also adding a new bimonthly column, "Pure C++," by my pal Stan Lippman, one of the great C++ Masters. Stan will cover more of the pure C++/CLI language stuff (he can tell you more himself), and I'll continue to write about the everyday application of C++, MFC (and now the Managed Extensions) to real-world Windows® programming, just as I've done for 11 years. Stan's new column represents the...

Since its introduction in 2002, ASP.NET has become the gold standard for Web applications run on servers powered by Microsoft® Windows®. In version 2.0 of the Microsoft .NET Framework, ASP.NET sheds its new-kid-on-the-block status. Its aim is to reduce the amount of code required to accomplish common Web programming tasks by 70 percent or more. New services, controls, and features make ASP.NET 2.0 almost as dramatic an improvement to ASP.NET 1.x as that was to ASP Classic.
Here's a broad ...

ASP.NET 2.0 introduces a series of new tools that improve data access including several data source and data bound controls. The new assortment of data source controls can eliminate a ton of repetitive code that was required in ASP.NET 1.x. For example, you can easily associate SQL statements or stored procedures with data source controls and bind them to data bound controls. Even more impressive, the ObjectDataSource control allows you to take advantage of the simplified development and reducti...
