Aquí les pongo el codigo de como creé los controles:
Código:
Private Sub ControlesParaFacturas(ByVal ListFacturas As ListBox)
Dim Num As Integer = ListFacturas.Items.Count
Dim xIniTB As Integer = 34
Dim yIniTB As Integer = 235
Dim xIniCB As Integer = 154
Dim yIniCB As Integer = 235
Dim xIniTt As Integer = 300
Dim yIniTt As Integer = 235
Dim Total As Double = 0
Dim Nombre As String
For i As Integer = 1 To Num
'Extraer los datos del Listbox
Dim dFact() As String = Split(ListFacturas.Items(i - 1), " | ")
'Agregar textbox
Dim txtBox As New TextBox
With txtBox
.Name = "txtFactura" & i
.Width = 100
.Height = 22
If i > 1 Then
yIniTB += 23
End If
.Location = New System.Drawing.Point(xIniTB, yIniTB)
.Text = dFact(0)
.ReadOnly = True
.BackColor = Color.Cornsilk
End With
Me.Controls.Add(txtBox)
'Agregar combobox
Dim cmbTP As New ComboBox
Dim Elementos() As String = {"PARCIAL", "TOTAL"}
With cmbTP
.Name = "cmbTP" & i
.Width = 121
.Height = 21
If i > 1 Then
yIniCB += 23
.Focus()
End If
.Location = New System.Drawing.Point(xIniCB, yIniCB)
.Items.AddRange(Elementos)
.SelectedIndex = 1
End With
Me.Controls.Add(cmbTP)
'Agregar controles para mostrar el total de la factura.
Dim txtTotal As New TextBox
With txtTotal
Nombre = "txtTotal" & i
.Name = Nombre
.Width = 100
.Height = 22
If i > 1 Then
yIniTt += 23
End If
.Location = New System.Drawing.Point(xIniTt, yIniTt)
.Text = dFact(1)
.TextAlign = HorizontalAlignment.Right
.ReadOnly = True
.BackColor = Color.Cornsilk
End With
Me.Controls.Add(txtTotal)
Total = Total + FormatNumber(txtTotal.Text, , , , TriState.False)
Next
Me.txtMontoCobrar.Text = FormatNumber(Total, 2, , , TriState.True)
End Sub
