Вы можете сделать свой собственный контроль.Вот пример / предложение, как это сделать с User control
, который можно повторно использовать в вашем приложении.пользовательский элемент управления удерживает панели в матрице, вы можете установить перетаскивание Event
для каждого Panel
элемента управления, и пользователь сможет поместить графическое окно на каждую панель:
УПРАВЛЕНИЕ ПОЛЬЗОВАТЕЛЕМ:
Public Class UserControl1
Public NumberOfPanelsInRow As Integer
Sub New(ByVal height As Integer, width As Integer, Optional ByVal numberofPanelsInRow As Integer = 3)
' This call is required by the designer.'
InitializeComponent()
' Add any initialization after the InitializeComponent() call.'
Me.Height = height
Me.Width = width
Me.NumberOfPanelsInRow = numberofPanelsInRow
End Sub
Private Sub UserControl1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
' grouped panels to hold picturebox you can drag & drop to them...'
Dim panelHeight As Integer = Me.Height / NumberOfPanelsInRow
Dim panelWidth As Integer = Me.Width / NumberOfPanelsInRow
Dim colors() As Color = {Color.Pink, Color.Black, Color.Red, Color.Cyan, Color.Green, Color.Orange,
Color.Red, Color.Pink, Color.Black, Color.Red, Color.Cyan, Color.Green, Color.Orange, Color.Red}
Dim total As Integer = NumberOfPanelsInRow * NumberOfPanelsInRow
Dim currentYlocation As Integer = 0
Dim currentXlocation As Integer = 0
Dim location As Point = New Point(0, currentYlocation)
Dim rowcounter As Integer = 0
Dim itemcounter As Integer = 0
For i = 1 To total
If rowcounter >= NumberOfPanelsInRow Then
rowcounter = 0
currentYlocation += panelHeight
currentXlocation = 0
End If
' to each one of this panel you can drag a picture box'
Dim p As New Panel
p.Size = New Size(panelWidth, panelHeight)
p.Location = New Point(currentXlocation, currentYlocation)
p.BackColor = colors(itemcounter)
Me.Controls.Add(p)
rowcounter += 1
itemcounter += 1
currentXlocation += panelWidth
Next
End Sub
End Class
ВЫЗОВ КОНТРОЛЯ ПОЛЬЗОВАТЕЛЯ ИЗ ФОРМЫ1:
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim uc = New UserControl1(300, 300)
Me.Controls.Add(uc)
End Sub
End Class
