The Rows property (collection) is used to store the data rows in a GridView control. The GridView control automatically populates the Rows collection by creating a GridViewRow object for each record in the data source and then adding each object to the collection. This property is commonly used to access a specific row in the control or to iterate though the entire collection of rows.

|---|
Only rows with their RowType property set to DataControlRowType.DataRow are stored in the Rows collection. The GridViewRow objects that represent the header, footer, and pager rows are not included in the collection. |
The following example demonstrates how to use the Rows collection to access the row being edited in a GridView control. After a row is updated, a message is displayed to indicate that the update was successful.
