Update requires a valid UpdateCommand

[lorena]

when passed DataRow collection with modified row - this is the error message I am getting when I try to update my datagridview.

The form is simple (or so I thought) - I just did the drag and drop and let VS2005 do all the code but when I try to update the datagridview, it deletes the information in the cell and I get the error message.

Here is my code:

Public Class RiskReleaseUsersForm

 Private Sub TDS_RR_EMPLOYEEBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TDS_RR_EMPLOYEEBindingNavigatorSaveItem.Click
   Me.Validate()
   Me.TDS_RR_EMPLOYEEBindingSource.EndEdit()
   Me.TDS_RR_EMPLOYEETableAdapter.Update(Me.RiskReleaseEmployeesDataSet.TDS_RR_EMPLOYEE)

 End Sub

 Private Sub RiskReleaseUsersForm_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) _
   Handles Me.FormClosing
   'Make sure validation events don't keep the form from closing
   e.Cancel = False
   'Show the main menu
   menuForm.Show()
 End Sub

 Private Sub RiskReleaseUsersForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
   'TODO: This line of code loads data into the 'RiskReleaseEmployeesDataSet.TDS_RR_EMPLOYEE' table. You can move, or remove it, as needed.
   Me.TDS_RR_EMPLOYEETableAdapter.Fill(Me.RiskReleaseEmployeesDataSet.TDS_RR_EMPLOYEE)

 End Sub

 Private Sub ExitToolStripMenuItem_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ExitToolStripMenuItem.Click
   Me.Close()
   'Show the main menu
   menuForm.Show()
 End Sub

End Class

What am I missing?
