Databinding programmaticall y

Databinding programmaticall y

In my webform I have the code below in the form_load procedure.

On the webform I have a GridView control. My question is simply how to bind
the GridView to the datasource in the code programatically .

Dim cnn As OleDbConnection

Dim strConnection As String

strConnection = "Provider=sqlol edb;Data Source=myServer ;Initial
Catalog=Intrane tt;;Persist Security Info=True;User
ID=sa;Password= myPassword"

cnn = New OleDbConnection

cnn.ConnectionS tring = strConnection

Dim myDataSet As DataSet

myDataSet = New DataSet("Artikl er")

Dim myDataAdapter As OleDbDataAdapte r

myDataAdapter = New OleDbDataAdapte r("", cnn)

Dim myCommand As OleDbCommand

myCommand = New OleDbCommand("S elect * from Artikler")

myDataAdapter.S electCommand = CommandObject

myDataAdapter.S electCommand.Co nnection = cnn

myDataAdapter.F ill(myDataSet, "Artikler")

Are you asking "why isn't my code working?".

I don't see a "CommandObj ect" in your sample code:

myDataAdapter.S electCommand = CommandObject

shoudn't that be

myDataAdapter.S electCommand = MyCommand

Yes you have right it should have been myCommand, but my question is not why
my code isn't working. I have a code that I know is OK (by testing the
rows.count ) but I am simply asking how to bind the data to the gridview on
the webform by code (not by the wizard used when dragging the gridview to
the form)

MyGridView.Data Source =myDataSet.Tabl es(0)
MyGridView.Data Bind()

This will bind with All columns. If you have set ItemTemplates and turned
off "Autogenera te Columns", then it will bind to the specified columns you've
defined ItemTemplates for.
