Question evaluating haserrors problem

[king_jeremy]

Hi,
I have a datagridview on a form and when I set errors on a column with setColumnError method the hasErrors evaluates just fine but when I set errors by DataGridView(RowIndex).ErrorText, hasErrors ignores it. What is it that I'm missing here?

This is the code I use

Private Sub StudentsDataGridView_CellEndEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles StudentsDataGridView.CellEndEdit
	If e.ColumnIndex = 1 Then
		For i As Integer = 0 To StudentsDataGridView.Rows.Count - 2
			If i <> e.RowIndex Then
				If Not IsDBNull(StudentsDataGridView(1, e.RowIndex).Value) AndAlso _
				   Not IsDBNull(StudentsDataGridView(1, i).Value) Then
					If StudentsDataGridView(1, e.RowIndex).Value = StudentsDataGridView(1, i).Value Then
						StudentsDataGridView(1, e.RowIndex).ErrorText = "This student name has been defined!"
						
						Exit For
					Else
						StudentsDataGridView(1, e.RowIndex).ErrorText = ""
					End If
				End If
			End If
		Next
	End If
End Sub

Why don't you just set the datacolumn to be Unique?
