A DataGrid is a data-bound control in ASP.NET that automatically iterates over records and generates HTML output, saving you from having to manually write for...next scripts inside HTML tags. A single row of the DataGrid control can be edited and updated using EditCommand and UpdateCommand events. An ADO.NET DataSet acts as an intermediate data store between the application and the database. In this article, Pandian demonstrates how multiple rows in a DataGrid can be updated at once. He also explores the flexibility of using DataSets and DataGrids in an ASP.NET application in the context of the following topics:

• Creating a dynamic DataGrid and DataSet
• Building a DataSet from the DataGrid
• Handling multiple postbacks in a single page
• Creating edit boxes for selected rows and columns
• Adding the validation controls for these edit boxes dynamically
• Adding live columns (with data) to the DataSets
• Updating the records of the DataGrid in one submit
• Exporting records of the DataGrid to an XML file
• Displaying XML records in the DataGrid
