Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView   26 Dec 2007 00:00 GMT

In November 2007 Microsoft released ASP.NET 3.5. As noted in An Overview of ASP.NET 3.5 and Visual Studio 2008, this released included two new ASP.NET data Web controls: the ListView and DataPager. In a nutshell, the ListView control provides a very flexible means for displaying a collection of data while still offerring rich data features like paging, sorting, editing, inserting, and deleting. The DataPager control can be associated with a ListView to render a paging interface.

Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

Disabling the Submit Button Until a CheckBox is Checked   19 Dec 2007 00:00 GMT

ASP.NET provides a variety of validation Web controls that can be used to validate a user's form field inputs. Unfortunately, the validation Web controls do not work with the CheckBox or CheckBoxList Web controls. In a previous article, Creating Validator Controls for the CheckBox and CheckBoxList, I shared two custom controls I had created to address this shortcoming: CheckBoxValidator and CheckBoxListValidator. These controls work like any other ASP.NET validation control - at a minimum, just add them to a page and specify their ControlToValidate and ErrorMessage properties.

A colleague recently asked me to enhance the CheckBoxValidator control's client-side script so that it could optionally disable a particular button when invalid. In particular, she wanted to be able to specify the ID of a Button control in the CheckBoxValidator's properties. The CheckBoxValidator would then use client script to disable (gray out) the Button when the CheckBoxValidator was invalid. The following screen shot illustrates this concept. On the left, the CheckBox is unchecked so the Submit button is grayed out; on the right, the CheckBox has been checked so the Button has become enabled.

I recently updated the CheckBoxValidator to meet these specifications. Read on to learn more about this new enhancement to the CheckBoxValidator!
