Never mind, i forgot to put "If Not Page.IsPostBack Then" on the page load section, so its sorted.
hi all,
i have a table in an access database like so
tbl_link(linkid, linkname, link)
im currently trying to get a datagrid to work so i can edit the records but i've run into a bit of trouble. the datagrid looks like this
the problem im having is that records wont update at all and im pretty positive that its due to the ID column being the wrong value but i can't work out how to sort the problem.
the rest of the code is like this
any ideas please,

Code:
<asp:DataGrid id="LinkGrid" runat="server" OnEditCommand="EditRecord" OnUpdateCommand="UpdateRecord" OnCancelCommand="CancelRecord" AutoGenerateColumns="False">
<Columns>
<asp:BoundColumn HeaderText="LinkID" DataField="linkid" />
<asp:BoundColumn HeaderText="Link Name" DataField="linkname" />
<asp:BoundColumn HeaderText="Actual Link" DataField="link" />
<asp:EditCommandColumn HeaderText="Editing" EditText="Edit" UpdateText="Update" CancelText="Cancel" />
</Columns>
</asp:DataGrid>
the problem im having is that records wont update at all and im pretty positive that its due to the ID column being the wrong value but i can't work out how to sort the problem.
the rest of the code is like this
Code:
Dim DBConnection As OleDbConnection
Dim DBCommand As OleDbCommand
Dim DBReader As OleDbDataReader
Dim SQLString As String
Sub Page_Load
BindDataGrid
End Sub
Sub BindDataGrid
'get all the data
End Sub
Sub EditRecord (Src As Object, Args As DataGridCommandEventArgs)
LinkGrid.EditItemIndex = Args.Item.ItemIndex
BindDataGrid
End Sub
Sub UpdateRecord (Src As Object, Args As DataGridCommandEventArgs)
Dim linkid = CType(Args.Item.Cells(0).Controls(0), TextBox).Text
Dim linkname = CType(Args.Item.Cells(1).Controls(0), TextBox).Text
Dim link = CType(Args.Item.Cells(2).Controls(0), TextBox).Text
SQLString = "UPDATE tbl_link SET " & _
"linkname = '" & linkname & "', " & _
"link = '" & link & "' " & _
"WHERE linkid = " & linkid
DBConnection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:\inetpub\db\bedb_las.mdb")
DBConnection.Open()
DBCommand = New OleDbCommand(SQLString, DBConnection)
DBCommand.ExecuteNonQuery()
DBConnection.Close()
LinkGrid.EditItemIndex = -1
BindDataGrid
End Sub
Sub CancelRecord (Src As Object, Args As DataGridCommandEventArgs)
LinkGrid.EditItemIndex = -1
BindDataGrid
End Sub
any ideas please,
