Cannot update record in datagridview

VB11

I have an application in VB .Net that connects to a database MS SQL. It is connected to a datagridview, the problem is when I add a new record when I update the dataset it accepts the 2 first cell values but the third cell becomes blank, if I click another row it exits rdit mode and accept all cell values if I press the update button.
here is the source

Private Sub SaveToolStripButton_Click(sender As Object, e As EventArgs) Handles SaveToolStripButton.Click
      Me.Table1BindingSource.EndEdit()

      If DataSet11.HasChanges Then
          Try
              SqlDataAdapter1.Update(DataSet11, "Table_1")
              DataSet11.AcceptChanges()
          Catch eUpdate As System.Exception

              'Throw eUpdate
              MsgBox(eUpdate.Message.ToString)
          End Try
      End If
  End Sub

Ant ideas?

What I have tried:

I have tried this in first line

Me.BindingContext(DataSet11, "Table_1").EndCurrentEdit()

but the same behavior seems that the code cannot stop the edit mode.
