SQL Server 2000 and VB

I have a simple application that has a form with a datagrid, text, and command button.  The user can type in a SQL statement in the text box and get the results in the grid, then the user can update data in the table.  

The problem I ran into was if there are more than 1 record displayed in the grid everything works ok.  The user can update the data like an excel spread.  

But if there is only one record in the grid, and the user tries to update it, it acts like it works, but it is not really updating it.  If the user update the 1 record, then turns around and queries it again to see if the update worked, it never works.

Does some know why this would happen?  It this a datagrid control bug?  Or is this a SQL server bug/ weirdness?

It is not a bug.
By default datagrid updates DB when the current record changed.
when there is only one record (and I think that user not allowed add new rows) user cannot change the record and force datagrid update the DB.
The solution is simple: put a button on the form, name it "Update" and call  to your recordset's .Update method when pressed.

I hope it helps

AllowAddNew = True
AllowArros = True
AllowDelete = True
AllowUpdate = True
CausesValidation = True
ColumnHeaders = True
DataMember = NULL
DataSource = NULL
DefColWidth = 0
Enabled = True
HeadLine = 1
Index = NULL
Netgotiate = False
RighttoLeft = False
TabAcrossSplits = False
TabStop = True
TAG = Null
Visible = true
WrapCellPointer = False

I use a typical connection string...   I am also using the ADODC control ...

  Connect = "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=" & txtUserName.Text & ";password=" & txtPassword.Text & ";Initial Catalog=SysDB;Data Source=myserver"




Adodc1.ConnectionString = Connect
Adodc1.recordsource = 'SELECT * FROM My_TABLE"
   
  Set DataGrid1.DataSource = Adodc1
