Treeview Question

[jpinto]

I've a treeview on my form that as a Parent node "Familia" and a child node "Ocorrencias". Here's the code:

Private Sub frmListaOcorrenciasTree_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim x, y As Integer
        Dim NomeFamilia, NomeOcorrencia As String
        Dim OcorrenciaNode As TreeNode
        trvOcorrencias.Nodes.Clear()
        trvOcorrencias.ImageList = ImageListTree
        trvOcorrencias.ImageIndex = 0
        Me.ListaOcorrenciasQueryTableAdapter.Fill(Me.ReportItDataSet.ListaOcorrenciasQuery)
        OcorrenciaBoolean = False
        conexao()
        sSQL = "SELECT * FROM [Familias]"
        da = New OleDb.OleDbDataAdapter(sSQL, con)
        ds.Clear()
        da.Fill(ds, "Familias")
        For x = 0 To ds.Tables("Familias").Rows.Count - 1
            NomeFamilia = ds.Tables("Familias").Rows(x).Item("Familia").ToString
            trvOcorrencias.Nodes.Add(NomeFamilia)
            sSQL2 = "SELECT [Descriçao] FROM [Ocorrencias] WHERE [Familia]='" & NomeFamilia & "' GROUP BY [Descriçao] ORDER BY [Descriçao] ASC"
            da2 = New OleDb.OleDbDataAdapter(sSQL2, con)
            ds2.Clear()
            da2.Fill(ds2, "Ocorrencias")
            For y = 0 To ds2.Tables("Ocorrencias").Rows.Count - 1
                NomeOcorrencia = ds2.Tables("Ocorrencias").Rows(y).Item("Descriçao").ToString
                OcorrenciaNode = trvOcorrencias.Nodes(x)
                OcorrenciaNode.Nodes.Add(NomeOcorrencia)
                OcorrenciaNode.ImageIndex = 1
            Next
        Next
        con.Close()
    End Sub

I'm putting an image to the parent node (index=0) and one to the child node (index=1) from an imagelist.

My problem is that when I click on the parent node, the image changes from the index 0 to the index 1, and when I click on other parent the image returns to the normal index 0 image.

Can annyone help me please?

Thanks,

João Pinto

Set the Parent node's SelectedImageIndex property to the same value as its ImageIndex property - in this case, 0.
