[英]Which auto generated picturebox was clicked? VB.net
I have the following code. 我有以下代码。 Im trying to find out which of the 64 pictureboxes was clicked: 我试图找出单击了64个图片框中的哪个:
For i As Integer = 1 To 8
For j As Integer = 1 To 8
SpilleBræt(i, j) = New PictureBox 'Opretter picturebox
If (i + j) Mod 2 = 1 Then
Me.SpilleBræt(i, j).BackgroundImage = Skak.My.Resources.DarkTile
Else
Me.SpilleBræt(i, j).BackgroundImage = Skak.My.Resources.LightTile
End If
'Placering, størrelse, m.v.
Me.SpilleBræt(i, j).Location = New System.Drawing.Point((i - 1) * 103, (j - 1) * 103)
Me.SpilleBræt(i, j).Size = New System.Drawing.Size(100, 100)
Me.SpilleBræt(i, j).Name = "SpilleBrik" & i & j
Me.PanelSpilleBræt.Controls.Add(Me.SpilleBræt(i, j))
Next j
Next i
Thanks. 谢谢。
In order to handle a click event, the first thing you'll need is a click handler. 为了处理单击事件,您需要的第一件事是单击处理程序。 Could be something as simple as this: 可能像这样简单:
Private Sub PictureBox_Click(ByVal sender As Object, ByVal e As EventArgs)
' Do something in here
End Sub
When you create your PictureBox
controls, bind the handler to their click event: 创建PictureBox
控件时,将处理程序绑定到其click事件:
AddHandler Me.SpilleBræt(i, j).Click, AddressOf PictureBox_Click
Me.PanelSpilleBræt.Controls.Add(Me.SpilleBræt(i, j))
What this should do is invoke the PictureBox_Click
method any time the user clicks on the PictureBox
. 用户应该在PictureBox_Click
单击PictureBox
时调用PictureBox_Click
方法。 Within that method, sender
is the element which was clicked: 在该方法中, sender
是被单击的元素:
Private Sub PictureBox_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim clickedBox As PictureBox
clickedBox = CType(sender, PictureBox)
' clickedBox is the element which was clicked
End Sub
