Save all records DATA Grid view by typing in it

Hi, can somebody help me about Save all records DATA Grid view by typing in it. I'm using vb 2010..

for example i have a grid and i type the records there after going to the next row it will be saved to the database.. I'm using MSSQL 2008 for the DB. I tried this one

Private Sub frmsetting_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.UtOTratesTableAdapter.Fill(Me._88PayrollDataSet.utOTrates)

    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Me.UtOTratesTableAdapter.Update(Me._88PayrollDataSet.utOTrates)
    End Sub

 but I received this error:Update requires a valid UpdateCommand when passed DataRow collection with modified rows.
