A reusable collapsible panel user control for web applications .
This is a reusable Collapsible Panel user-control for web applications.Often we encounter web pages that run very long and it becomes difficult for the user to navigate down, dragging his mouse along all the way. So, when we want to display all the stuff on the same page and still keep it easy for the user, we could group pieces of related information into a collapsible panel. This is what got me working on this user-control. Th...

Reuse is a technique that is important to most developers. Reuse allows you to avoid constantly reinventing the wheel by using functionality that has already been built and tested. It increases productivity, by reducing the total amount of code you need to write, and reliability, since by using tested code, you (presumably) already know the code works reliably....

How many times where you required to let user select some data from the database? This means allowing the user to check some ticks on the data from the database and then to perform some actions based on the selected items.
In ASP.NET 2.0 there are two controls that could do the trick: CheckBoxList and RadioButtonList. These controls allow you to set a DataSource property to them and they will handle all the work. However, if you need to get the selected items in the list, you have to do t...

In this article I am going to show you one technique for adding a "drill down" feature to a DataGrid. In the code that accompanies this article, the summary page consists of a simple DataGrid control, with three columns. The DataGrid is bound in the code-behind to a data reader representing the Categories in the Northwind database. The third column contains an indication of the number of products that are in the category, rendered as a Link Button. Clicking the Link Button causes the page to ...

Some user controls are entirely self contained, for example, a user control displaying current stock quotes does not need to interact with any other content on the page. Other user controls will contain buttons to post back. Although it is possible to subscribe to the button click event from the containing page, doing so would break some of the object oriented rules of encapsulation. A better idea is to publish an event in the user control to allow any interested parties to handle the event....

Displaying data in ASP.NET verison 1.x required writing code to programmatically retrieve the data and then more code to bind the data to a data Web control, such as the DataGrid. ASP.NET 2.0 simplifies the process of working with data through its data source controls, which allow data to be retrieved and even modified through declarative means. In short, ASP.NET 2.0's data source controls permit developers to work with and display data without having to write a line of code. For a more thorough...
