The another problem is after populating how to display or show current database value by default in Drop Down List as a Selected Value in edit mode.
In this example I will give you a complete solution on “How to operate Drop Down List in Grid View Edit Mode“ CREATE TABLE [dbo].[Brand]( [ID] [bigint] NOT NULL, [Name] [varchar](max) NOT NULL, CONSTRAINT [PK_Brand] PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] CREATE TABLE [dbo].[Product]( [ID] [bigint] NOT NULL, [Name] [varchar](max) NULL, [Description] [varchar](max) NULL, [Brand ID] [bigint] NULL, CONSTRAINT [PK_Product_2] PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] INSERT INTO Brand Values(1,'Kohinoor') INSERT INTO Brand Values(2,'Proctor & Gamble') INSERT INTO Brand Values(3,'Telenor') INSERT INTO Brand Values(4,'Unilever') INSERT INTO PRODUCT VALUES(1,'Lux Beauty Soap','Product of Unilever',4) INSERT INTO PRODUCT VALUES(2,'Tibbet Pomed','Winter Product',1) INSERT INTO PRODUCT VALUES(3,'Data SIM','Subscriber Identity Module',3) INSERT INTO PRODUCT VALUES(4,'Nippon','Color Television',1) Note: If you look at the Grid View events you will get onrowdatabound, onrowupdating, onrowediting, onrowcancelingedit events. Like onrowdatabound event will fire when Grid View Data Bind() method was called, onrowediting event will fire when user click on Edit link, onrowupdating event will fire when user click on Update link & onrowcancelingedit will fire when user click on Cancel link.
Grid View Row row = (Grid View Row)(((Link Button)e.

Therefore, you should test for the optimum batch size setting before implementing your application. Errors are handled the same way in batch mode as they are when batch mode is disabled. Only rows that have been successfully processed in the database will be updated in the corresponding Data Row within the Data Table.
Dim connection String As String = Get Connection String() ' Connect to the Adventure Works database. When performing a batch update, the command's Updated Row Source property value of First Returned Record or Both is invalid. Product Category (Name) VALUES (@Name);", _ connection) adapter. An exception may be thrown if a non-supported statement is submitted for execution.The following procedure demonstrates the use of the property. Data Adapters and Data Readers Updating Data Sources with Data Adapters Handling Data Adapter Events ADO.The procedure takes two arguments, a Data Set object that has columns representing the Product Category ID and Name fields in the Production.
Product Category table, and an integer representing the batch size (the number of rows in the batch).
NET allows a Data Adapter to group INSERT, UPDATE, and DELETE operations from a Data Set or Data Table to the server, instead of sending one operation at a time. Every row update involved a network round-trip to the database. NET 2.0, the Db Data Adapter exposes an Update Batch Size property.
