The only thing I could check is:

MsgBox(myDS.Tables("Measure").HasErrors)

and it shaws False, no errors, my update statments inside a Try, Catch method, so if there are any error it will display a message.

This is the new news about what I found, any row I change in the datagrid it shows the position as "0", so as I said before it's position problem:

MsgBox(Me.BindingContext(myDS, "Measure").Position)

I am not able to find the code to know the position of the selected record in the datagrid, can you help me in this?


>That sounds like a good place to start. I would trace through the code and look at the state of the DataSet before trying to update.
