Consegui, Alterei o comando "Private Sub cbxOperacao_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)" para: "Private Sub cbxOperacao_SelectedIndexChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbxOperacao.SelectedIndexChanged" Obrigado!

Cara, Obrigado pela atenção! Mas não deu certo! Tentei mudar os códigos aplicando o VB, ao invéz de asp.

Olá, sou novo por aqui e gostaria que me ajudassem a resolver um problema com os combobox relacionados. Sendo o primeiro combo = cbxOperacao o segundo = cbxSupervisor e o terceiro = cbxDiretor O sistema consegue pegar a informação do primeiro combo, mas não puxa as informações do segundo e terceiro. Segue código: Private Sub PreencheOperacao() Dim con As New SqlConnection(strCon) Dim cmd As New SqlCommand() cmd.Connection = con cmd.CommandType = CommandType.Text cmd.CommandText = "SELECT ope_id, ope_nome FROM TBcad_operacao" Dim objDs As New DataSet() Dim dAdapter As New SqlDataAdapter() dAdapter.SelectCommand = cmd con.Open() dAdapter.Fill(objDs) con.Close() cbxOperacao.ValueMember = "ope_id" cbxOperacao.DisplayMember = "ope_nome" cbxOperacao.DataSource = objDs.Tables(0) End Sub Private Sub cbxOperacao_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) If cbxOperacao.SelectedValue.ToString() <> "" Then Dim ope_id As Integer = Convert.ToInt32(cbxOperacao.SelectedValue.ToString()) PreencheSupervisor(ope_id) cbxDiretor.SelectedIndex = 0 End If End Sub Private Sub PreencheSupervisor(ByVal ope_id As Integer) Dim con As New SqlConnection(strCon) Dim cmd As New SqlCommand() cmd.Connection = con cmd.CommandType = CommandType.Text cmd.CommandText = "SELECT sup_id, sup_nome FROM TBcad_supervisor WHERE ope_id =@ope_id" cmd.Parameters.AddWithValue("@ope_id", ope_id) Dim objDs As New DataSet() Dim dAdapter As New SqlDataAdapter() dAdapter.SelectCommand = cmd con.Open() dAdapter.Fill(objDs) con.Close() If objDs.Tables(0).Rows.Count > 0 Then cbxSupervisor.ValueMember = "sup_id" cbxSupervisor.DisplayMember = "sup_nome" cbxSupervisor.DataSource = objDs.Tables(0) End If End Sub Private Sub cbxSupervisor_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Dim sup_id As Integer = Convert.ToInt32(cbxSupervisor.SelectedValue.ToString()) PreencheDiretor(sup_id) End Sub Private Sub PreencheDiretor(ByVal sup_id As Integer) Dim con As New SqlConnection(strCon) Dim cmd As New SqlCommand() cmd.Connection = con cmd.CommandType = CommandType.Text cmd.CommandText = "SELECT dir_id, dir_nome FROM TBcad_diretor WHERE sup_id =@sup_id" cmd.Parameters.AddWithValue("@sup_id", sup_id) Dim objDs As New DataSet() Dim dAdapter As New SqlDataAdapter() dAdapter.SelectCommand = cmd con.Open() dAdapter.Fill(objDs) con.Close() If objDs.Tables(0).Rows.Count > 0 Then cbxDiretor.ValueMember = "dir_id" cbxDiretor.DisplayMember = "dir_nome" cbxDiretor.DataSource = objDs.Tables(0) End If End Sub End Class
