My datagrid's datasource is a db table.

If the user edits a cell, how do I update the db with the change?  

I need to know what value has changed and make an update to SQL Server.

A code snippet, svp.

Hello

  Use SqlDataAdapter to fill Dataset, and then bind the DataGrid to the Dataset
when you would like the changes that happen to the Datagrid to be updated to sql server, use SqlDataAdapter.Update for that

it's easy and doesn't require from you much code ;-)

Sample code.............

    Public DS As DataSet
    Public CurRow As DataRow
    Public sTableName As String = "MyTable"
    Public myDataAdapter As OleDb.OleDbDataAdapter
    Dim icnt As Short = 0

        For Each CurRow In DS.Tables(sTableName).Rows
            CurRow.BeginEdit()
            CurRow("OnHand") = datagrid.Item(icnt, 1)         '<---- Column 1
            CurRow("Name") = datagrid.Item(icnt, 2)            '<---- Column 2
            CurRow.EndEdit()
            icnt +=1
        Next
        myDataAdapter.Update(DS.Tables(sTableName))
        MsgBox("Records edited successfully")

I'd use the commandBuilder class since it's a single table.
