Editing a datagrid whose datasource is a query

I'll get this thing working if it kills me.

I have a datagrid whose datasource is a SQL query.
The infromation is displayed in the grid OK. When i click
on a cell to edit it i can change the value but when i click
on another cell i get the following message:-


'insufficient base table information for updating
or refreshing'

When i have the datasource as a single table i can
edit and update cells fine.

Can anyone point me in the right direction


Below is the code i use
___________________________________________________

Public Sub PopulateGrid()

Dim Cmd As New ADODB.Command
Dim rs As New ADODB.Recordset
'frmMain.MyContractID = 1

dgdRateEntry.Visible = True


Set Cmd.ActiveConnection = frmMain.conn
Cmd.CommandType = adCmdText


Cmd.CommandText = "SELECT cl.event , cl.eventdescription, lp.Rate, " _
& "lp.rate as oldrate,'U' as flag" _
& " From linepayment lp,contractline cl" _
& " Where lp.contractlineid = cl.contractlineid" _
& " AND lp.contractid =" & frmMain.MyContractID & " Union" _
& " SELECT cl.event , cl.eventdescription, 0, " _
& " 0 as oldrate, 'I' as flag" _
& " From contractline cl " _
& " Where Not Exists" _
& " (Select * from linepayment lp " _
& " Where lp.contractlineid = cl.contractlineid " _
& " and lp.contractid=" & frmMain.MyContractID & ")"



rs.CursorType = adOpenDynamic
rs.CursorLocation = adUseClient
rs.Open Cmd, , adOpenDynamic, adLockOptimistic
Set dgdRateEntry.DataSource = rs
dgdRateEntry.ReBind


End Sub

Puma,

Sorry, this is not the solution to your problem, but I thought maybe you can help me...

Reading your post, I am trying to do something smilar. At design time, I don't know the name of the database I am going to access, so I can't bind it permanently to an ADO data control for instance.

Here is my code:

Code:

---

Dim cd As New ADODB.Command
Dim rs As New ADODB.Recordset

' That's the name that could change...
cd.ActiveConnection = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=c:\VB Projects\CD400\CD400.mdb;"

cd.CommandType = adCmdText
cd.CommandText = "select * from EMPLOYEE_IDS"

rs.Open cd, , adOpenStatic, adLockOptimistic

Set DataGrid.DataSource = rs

DataGrid.ReBind

---

I am getting the following error when executing the 'ReBind' method: "Cannot initialize data bindings"

Am I missing something ?
