this is for the asp .net datagrid, but the main code is exactly the ame, just remove the html and asp stuff, and remove the .DataBind method
Code:
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.OleDb"%>
<html>
<script language="VB" runat="server">
' ---------------------------------
' Code by Chris Andersen
' This example shows how to show data from an access database in the DataGrid control
' and how to write a new record to the database.
' ---------------------------------
' Recordset no longer exists for ADO .NET. Create DataSets and populate it from the data you get from
' a DataAdapter or other source. In this case we are getting ADO DataSet using the System.Data.OleDb.OleDbDataAdapter Class
Dim myDS As New DataSet
Dim myConn As OleDbConnection
Dim myCommand As OleDbDataAdapter
Dim strConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;data source=" & Server.Mappath("/candersen/db/test.mdb")
Dim strSQL As String
Sub Page_Load(Sender As Object, E As EventArgs)
' This sub is called everytime the Page Loads
End Sub
Sub Go_Click(Sender As Object, E As EventArgs)
Dim strName As String = Name.Text
Dim strAge As String = Age.Text
' Write posted data to the lables
lblName.Text = strName
lblAge.Text = strAge
' Insert Posted Data to database
strSQL = "Insert Into Test(Name,Age) VALUES('" & strName & "','" & strAge & "')"
' Populate DataSet
FillDataSet()
' Update DataGrid
UpdateGrid()
End Sub
Sub UpdateGrid()
' Updates the DataGrid
strSQL = "Select * FROM Test"
'Populate DataSet
FillDataSet()
' Now set the DataGrid's source to the Dataset and bind it
MyDataGrid.DataSource = myDS.Tables("Test").DefaultView
MyDataGrid.DataBind()
End Sub
Sub FillDataSet()
' Reusable code to populate the Dataset from the SQL statement
'Start Connection to ADO source
myConn = New OleDbConnection (strConnString)
' Run the Sql statement and get the Data into the DataAdapter
myCommand = New OleDbDataAdapter(strSQL, myConn)
' Fill the DataSet and name the table
myCommand.Fill(myDS, "Test")
myConn.Close()
End Sub
