Type 'GridViewRow' non défini

Bonjour,
qlq 1 peut m'aider à résoudre ce problm?
voici mon code:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
For rowIndex As Integer = DataGrid1.Rows.Count - 2 To 0 Step -1
Dim gviewRow As GridViewRow = GridView1.Rows(rowIndex)
Dim gviewPreviousRow As GridViewRow = GridView1.Rows(rowIndex + 1)
For cellCount As Integer = 0 To gviewRow.Cells.Count - 1
If gviewRow.Cells(cellCount).Text = gviewPreviousRow.Cells(cellCount).Text Then
If gviewPreviousRow.Cells(cellCount).RowSpan < 2 Then
gviewRow.Cells(cellCount).RowSpan = 2
Else
gviewRow.Cells(cellCount).RowSpan = gviewPreviousRow.Cells(cellCount).RowSpan + 1
End If
gviewPreviousRow.Cells(cellCount).Visible = False
End If
Next
Next
End Sub

le msg qui s'affiche est: Type 'GridViewRow' non défini

Bonjour

Tout d'abord, merci de mettre le code entre balise [CODE]. Ca facilite la lisibilité.

Ensuite, c'est quoi comme appli ? Du WinForm ou de l'ASP.net ?
WinForm : DataGridViewRow
ASP.net : GridViewRow

Enfin, un moyen simple de trouver ce type d'erreur est de voir ce que doit retourner GridView1.Rows(rowIndex)

merci de ta réponse.
le code est :

Code:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
For rowIndex As Integer = DataGrid1.Rows.Count - 2 To 0 Step -1
Dim gviewRow As GridViewRow = GridView1.Rows(rowIndex)
Dim gviewPreviousRow As GridViewRow = GridView1.Rows(rowIndex + 1)
For cellCount As Integer = 0 To gviewRow.Cells.Count - 1
If gviewRow.Cells(cellCount).Text = gviewPreviousRow.Cells(cellCount).Text Then
If gviewPreviousRow.Cells(cellCount).RowSpan < 2 Then
gviewRow.Cells(cellCount).RowSpan = 2
Else
gviewRow.Cells(cellCount).RowSpan = gviewPreviousRow.Cells(cellCount).RowSpan + 1
End If
gviewPreviousRow.Cells(cellCount).Visible = False
End If
Next
Next
End Sub

et j'utilise comme application winform.

Donc comme je le disais dans mon précédent post, GridView1.Rows(rowIndex)
retourne un DataGridViewRow et non un GridViewRow.
