Rowupdating event in c

In this example I will give you a complete solution on “How to operate Check Box 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 use windows authentication then use the first key. Update server name, Database name, User name, Password as per your settings. Is Post Back) Bind_Check Box List(); } private void Bind_Check Box List() { Data Table dt; String SQL = "SELECT P. Now add the Grid View Control like Below: 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.

I have a gridview row that when clicked has to do postback A and a buttonfield in that row that when clicked has to do postback B.

The problem is that when i click on the buttonfield, both event1 and event2 gets fired. protected void gdv_Row Command(object sender, Grid View Command Event Args e) { string arg = Convert.

Command Name == "Command2") { do Event2(arg); } } protected void gdv_Row Data Bound(object sender, Grid View Row Event Args e) { if (e.

Command Name == "Command1") { do Event1(arg); } else if (e.

Command Argument = arg1; Link Button row Link = (Link Button)e.

Net) developers faced a problem when they want to implement edit functionality within a Grid View. Name Brand" + " FROM Product P, Brand B" + " WHERE P.

The problem is developers can not understand how to populate or Bind data into Check Box List within the Grid View in Edit Mode.

The another problem is after populating how to display or show current database value by default in Check Box List as a Selected Value in edit mode. Now first Bind or Load the Grid View Control: C# Code: protected void Page_Load(object sender, Event Args e) { if (!
