Vb net gridview onrowupdating

In my previous tutorials, I’d explained about how to bind data to gridview, how to get connection string, insert update delete gridview data using parameterized query, difference between executereader executenonquery and executescalar and other more cracking tutorials on Grid View, Asp.net, SQL Server here.

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.

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 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.

(Note, in the gridview the Enable View State="False" - if I set it to True I get the standard "Failed to load viewstate. error) One strange thing that I've noticed that makes me think it's a View State problem is that if I change the Command Name of the Update button to "Edit" that postback event does get captured in the Row Command event... Something in my inheritance stack (or something in the MS controls) didn't work the way I had it set up.

Hi I have gridview and I am using gridview1_rowupdating event to update the gridview, but when I am using the code given below its not working.

Keep in mind in every event we need to rebind the Grid View Note: Don’t forget to add “System.

Open() Using da As Sql Data Adapter = New Sql Data Adapter(comm) dt = New Data Table("tbl") da. Open() Using da As New Sql Data Adapter(comm) dt = New Data Table("tbl") da.

My problem lies in that the click on the Update Image Button posts back, but neither the Row Command nor Row Updating events get triggered.

I have set the requisite attributes in the Grid View tag. I removed the master page and let the page that contained the Grid View inherit from Page, and it worked.

You have to make sure that you aren't setting your Grid View's data when it is not postback.
