Paging, Selecting, Deleting, and Editing in the ASP.NET 2.0 GridView Control with Keyboard Shortcuts

The ASP.NET 2.0 framework comes with the GridView, a feature-rich ASP.NET server control to display, page through, and edit data on a webpage. Paging, selecting, and editing of the GridView is achieved by declaratively adding properties to the markup of the GridView. This adds link buttons to the data rows of the GridView. You have to click on one of the link buttons to delete or edit a row. One feature I missed is the ability to use these features via keyboard shortcuts.

To achieve that, I developed an ASP.NET 2.0 AJAX Extensions Extender Control for use with ASP.NET 2.0 GridView on ASP.NET 2.0 AJAX enabled web pages.

Generate an Image with a Random Number

We need to check if it is a real person who is registering on our Web site. So we decided to generate an image with a random code, hidden for robots, and feed it to the browser instead of a page response. We show it in our registration form, and let the user enter the code to check it.

PleaseWaitButton ASP.NET Server Control

It is often useful upon a form submission in a web application to display a "please wait" message, or animated .gif image, particularly if the submission process lasts a few seconds or more. The application inserts the uploaded data from the spreadsheets into a database. The upload/insert process may only take a few seconds, but even a few seconds on the web is a noticeable wait.

When testing, some users clicked the upload button repeatedly; it was useful to provide a visual clue that the upload was underway. For that matter, it was useful to hide the upload button altogether, preventing multiple clicks. The control presented here, a subclass of the Button control, demonstrates how client-side JavaScript code encapsulated in an ASP.NET server control can provide such functionality conveniently.

ASP.NET File Uploader with Overwrite Message

This ASP.NET application is a file uploader dialog box that can be called from classic ASP. It is designed for use in an intranet site. The file uploader displays an overwrite warning as a popup or a warning message. The overwritten file is archived with a time stamp appended to the filename. Checking if the file already exists turned out to be the biggest obstacle. The FileExists Java function uses an ActiveX control that causes browser security warnings. The workaround was to access a code-behind routine by calling AJAX Web Services.

DropDown and MultiselectDropDown Controls for ASP.NET

This article discusses about two user controls written in ASP.NET. Working on a project recently, I needed to develop a custom DropDown control with multiselect options in the form of CheckBox. I searched around for something simple, yet useful for my needs, and I wasn't able to find anything, so I developed my own control. Later, I reused the code to create a regular DropDown control (no multiselect checkbox options). The two controls can be merged into one, but I might do that at a later stage. On to the controls.

CAPTCHA stands for "completely automated public Turing test to tell computers and humans apart." What it means is, a program that can tell humans from machines using some type of generated test. A test most people can easily pass but a computer program cannot.

You've probably encountered such tests when signing up for an online email or forum account. The form might include an image of distorted text, like that seen above, which you are required to type into a text field.

Please Wait Button ASP.NET Server Control

It is often useful upon a form submission in a web application to display a "please wait" message, or animated .gif image, particularly if the submission process lasts a few seconds or more. I recently developed a survey submission application in which internal users upload excel spreadsheets through a web page. The application inserts the uploaded data from the spreadsheets into a database.

The upload/insert process may only take a few seconds, but even a few seconds on the web is a noticeable wait. When testing, some users clicked the upload button repeatedly; it was useful to provide a visual clue that the upload was underway.
