detecting delete on row in datagridview and updating dataset
 

i have a datagrid which show values in a dataset.

I can add new values fine with the below code, but when i delete one of the rows (highlighting a row and using the delete key) i get the error:

'Update requires a valid DeleteCommand when passed DataRow collection with deleted rows.'

this is flaggin on the bolded line below

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click



        Dim drNew As System.Data.DataRow



        drNew = Me.ISurfDataSet.Urls.NewRow

        drNew.Item("URLLink") = urlTextBox.Text

        Me.ISurfDataSet.Urls.Rows.Add(drNew)



        Changes = True 'set the flag to show that changes have been made



    End Sub



    Sub AddData() ' add the new urls to the database







        Me.Validate()

        Me.UrlsBindingSource.EndEdit()

        Me.UrlsTableAdapter.Update(Me.ISurfDataSet.Urls)



        MsgBox("All new data added successfully!")



        Changes = False ' all canges have been saved so the form can close



        Me.Close()



    End Sub



    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

        Call AddData() ' call the function to add the new urls to the database



    End Sub



    Private Sub UrlsDataGridView_UserDeletedRow(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewRowEventArgs) Handles UrlsDataGridView.UserDeletedRow

        Me.Validate()

        Me.UrlsBindingSource.EndEdit()

        Me.TableAdapterManager.UpdateAll(Me.ISurfDataSet)

    End Sub
