I have one gridview I need to write code to insert data into gridview after that I need to edit that gridview data and update it and if I want to delete the record in grdview we need to delete record simply by click on delete button of particular row to achieve these functionalities I have used some of gridview events those are By Using above griview events we can insert, edit, update and delete the data in gridview.
After you have run the website, you will see the Grid View showing details of employees in tabular format.
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.
However, you will need to provide an appropriate event handler with the implementation for these operations. The automatic updating, deleting, and selection functionalities are enabled when a button in a Button Field or Template Field column field, with a command name of "Edit", "Delete", and "Select", respectively, is clicked.
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 System. Note The Grid View control can provide support for sorting, updating, and deleting with other types of data sources.
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.
