DREAMWEAVER CS3 691 User Guide Preselect an ASP.NET RadioButton control You can let the server determine which RadioButton in a group is selected. At run time, the server compares each checked value you specified to a value in a DataSet. If the values match, the server checks the RadioButton. For more information on ASP.NET RadioButton properties, see the documentation on the Microsoft website at http://msdn.microsoft.com/library/en-us/cpgenref/html/cpconradiobuttonwebservercontrol.asp. ❖ Select the Dynamic option in the Properties inspector and set the Dynamic Radio Group options. Creating ASP.NET DataGrid and DataList web controls Comparing the ASP.NET DataGrid and DataList controls The ASP.NET DataGrid and DataList controls provide numerous options for displaying different data types (especially dynamic content from a database), and simplify the process of binding data sources to the controls. Dreamweaver supports both the DataGrid and DataList controls as server behaviors. The controls provide the following features: DataGrid creates a multi-column, data-bound grid. This control allows you to define various types of columns, both to lay out the contents of the grid and to add specific functionality (edit button columns, hyperlink columns, and so on). DataList displays items from a data source using templates. You can customize the appearance of the control by manipulating the templates that make up its different components. About the ASP.NET DataGrid web control The Dreamweaver DataGrid allows you to insert an ASP.NET DataGrid web control. The DataGrid control renders tables as multi-column grids, and can include different column types (heterogeneous columns) for defining the layout of cell contents. These include bound, button, and template columns, among others. In addition, the DataGrid supports interactive functionality such as column sorting, editing, and commands. The following table shows the column types that are available in the DataGrid: DataGrid Column Type Simple Data Field Free Form Description Referred to as a "bound column" in ASP.NET, the Simple Data Field column lets you specify which data source field to display, and the data format the field will use with a .NET formatting expression. Referred to as a "template column" in ASP.NET, the Free Form column type lets you create combinations of HTML text and server controls to design a custom layout for a column. The controls within a free-form column can be data-bound. Free-form columns give you added flexibility in defining the layout and functionality of the grid contents, because you have complete control over how the data is displayed and what happens when users interact with rows in the grid.
