Need some help updating the database from my datagrid.

The code that populates the grid is...
        m_da = New SqlClient.SqlDataAdapter(strSql, pStrConnection)

        m_ds = New DataSet("mytestds")
        m_da.Fill(m_ds, "mytestds")

        dgDH51.SetDataBinding(m_ds, "mytestds")
        cn.Close()

I was trying to update the db using ....

        m_da.Update(m_ds, "mytestds")

But I get this error. I am guessing what to do as I can't find any good examples.

An unhandled exception of type 'System.InvalidOperationException' occurred in system.data.dll

Additional information: Update requires a valid UpdateCommand when passed DataRow collection with modified rows.

Thanks
Andy
