Gridview rowediting rowupdating
For this situation, many developers use invisible columns (Hidden columns) in the gridview to identify that row. We can achieve the same functionality using Datakeys. Set the Data Key Names property of Grid View to Primary Key Column of Data Base i.e. This property binds the database column field value to each row of gridview as a Unique Identifier.Set the data bindings for Delete Button for Command Argument Eval(“Emp Id”); for saving the ID column value from database for fetching the ID field value while Deleting the Record.Add Edit button from Command Field Group from Property Window.Template Field Colums have Item Template, Alternating Item Template, Edit Template, Header Template, Footer Template.In this example, I am going to retrieve values from categories table of Northwind database. Drag a Grid View into the Web Form and assign Data Key Names property with the primary key column i.e. In the gdview_Row Editing and gdview_Row Deleting event, we have used the below code to retrieve categoryid from datakey of Grid View, int catid = int.
Go to property builder by right click on Grid View - Edit Columns.
On Row Deleting - can call registered event handlers" I couldnt figure out how to continue this thread, but the issues in it are related so i'm including it as a reference.
In my custom grid View control I cannot raise the Row Updated event.
A datakey represents the primary key field or field of a record that can uniquely identify it in a data-bound control. Row Index represents the index of the particular row.
Many a times in our applications we use primary keys to get control of the particular record in the gridview.
