Sorry i am just repeating a question that has been asked a million times, but every answer seems to be either too advanced or not satisfying. I have a simple gridview .. and it shows all the values in the table its connected too .. but when i edit or delete .. the values in the table do not get updated .. Here is my code .. hope you guys can help me ..

CODE
[b]1    [/b]<%@ Page Language="VB" %>
[b]2    [/b]<%@ Import Namespace="System.Data" %>
[b]3    [/b]<%@ Import Namespace="System.Data.OleDb" %>
[b]4    [/b]<script language="VB" runat="server">
[b]5    [/b]    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
[b]6    [/b]        Dim myConnection As New OleDbConnection
[b]7    [/b]        myConnection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; " _
[b]8    [/b]         & "Data Source=" & Server.MapPath("App_Data\origin_ts.mdb") & ";")
[b]9    [/b]        Dim myCommand As New OleDbCommand
[b]10   [/b]        myCommand.Connection = myConnection
[b]11   [/b]        myCommand.CommandText = "SELECT * FROM TimeSheet"
[b]12   [/b]        myCommand.CommandType = CommandType.Text
[b]13   [/b]        Dim myda As New OleDbDataAdapter
[b]14   [/b]        myda.SelectCommand = myCommand
[b]15   [/b]        Dim mydg As New GridView
[b]16   [/b]        'Me.GridView1.DataBind()
[b]17   [/b]        Dim dss As New AccessDataSource
[b]18   [/b]        dss.DataBind()
[b]19   [/b]        Dim myds As New DataSet
[b]20   [/b]        myda.Fill(myds, "TimeSheet")
[b]21   [/b]
[b]22   [/b]    End Sub
[b]23   [/b]
[b]24   [/b]    Protected Sub btlogout_Click(ByVal sender As Object, ByVal e As System.EventArgs)
[b]25   [/b]        FormsAuthentication.SignOut()
[b]26   [/b]        Response.Redirect("login.aspx")
[b]27   [/b]    End Sub
[b]28   [/b]
[b]29   [/b]</script>


This is my Script code ...

Now here is my html code for the gridview:

CODE
[b]1    [/b]  <asp:AccessDataSource ID="AccessDataSource1" runat="server" ConflictDetection="CompareAllValues"

[b]4    [/b]                                OldValuesParameterFormatString="original_{0}" SelectCommand="SELECT * FROM [TimeSheet] WHERE ([UserName] = ?)"
[b]5    [/b]                                UpdateCommand="UPDATE [TimeSheet] SET [Day_Date] = ?, [UserName] = ?, [Client Name] = ?, [Job Description] = ?, [Job Type] = ?, [Hours] = ?

[b]60   [/b]                                <AlternatingRowStyle BackColor="PaleGoldenrod" />
[b]61   [/b]                            </asp:GridView>


I cant find anything wrong here, so how can i manually update this or delete a value .. or please suggest any other alternative ?

TimeSheet Table has the Following:
  • TimeSheetID --> This is the Primary Key
  • Day_Date
  • UserName
  • Client Name
  • Job Description
  • Job Types
  • Hours
And the Column names are exactly as in my table, I hope the capital and spaces don't make a difference. Should i be changing the primary key to something else ? Like Day_Date ? Cause UserName is Primary key of User table and Client Name is primary key of Client table. So basically its just 3 tables and its pretty simple, but i have no clue where i am going wrong.

Thanks in Advance .. Regards
