Difference between rowediting and rowupdating in gridview Free unregistered video chat
Each column represents a field, while each row represents a record.
The Grid View control is used to display the values of a data source in a table.
Here we use a Template Field inside a grid view control.

The Columns collection stores all the column fields in the control and enables you to programmatically manage the column fields in the Grid View control. For more information, see Introduction to the Validation Controls.
The following table lists the different column field types that can be used. The columns specified are added to the Columns collection in the order listed. Validation server controls are also provided to assess user input.

The Grid View control supports the following features: , which creates an Auto Generated Field object for each field in the data source. before that i want just using Find control and casting and then retrieving all lot code. If values are same they could notify user to change the value(give new cell value). Every one can use it to compare the new value with old ones. When both are used, explicitly declared column fields are rendered first, followed by the automatically generated column fields. When the Grid View control is bound to a data source control, the Grid View control can take advantage of the data source control's capabilities and provide automatic sort, update, and delete functionality. Explicitly declared column fields can be displayed in combination with automatically generated column fields. The Grid View control provides many built-in capabilities that allow the user to sort, update, delete, select, and page through items in the control.
