Note: The Grid View control can provide support for sorting, updating, and deleting with other types of data sources. 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. The following table lists the different column field types that can be used. The Grid View control can be bound to a data source control (such as the Sql Data Source control or Object Data Source control) or to any data source collection that implements the IEnumerable interface, such as Data View, Array List, List`1, or other collection types. Different column field types determine the behavior of the columns in the control. When both are used, explicitly declared column fields are rendered first, followed by the automatically generated column fields.I am using Template Field’s Item Template and Edit Item Template for providing read only and editing interface of the same column in the Grid View.By Default, Grid View control displays Item Template which directly shows the Product Name and Unit Price columns but when user clicks Edit button Grid View automatically switches to Edit Item Template and display the control available inside Edit Item Template for user editing.Enable View State property must also be set to true to ensure that concurrent data operations, such as updates and deletes, apply to the appropriate row.
Instead of displaying all the records in the data source at the same time, the Grid View control can automatically break the records up into pages. Causes Validation property set to true, then the Page.
Sorting allows the user to sort the items in the Grid View control with respect to a specific column by clicking on the column's header. The Grid View control can automatically add a Command Field column field with an Edit, Delete, or Select button if the Grid View. Note: Inserting records into the data source is not directly supported by the Grid View control.
However, it is possible to insert records by using the Grid View control in conjunction with the Details View or Form View control.
In the above code, I set two properties Show Edit Button and Show Cancel Button of Command Field.
These properties will automatically render Edit, Update and Cancel buttons inside Grid View column.
