推荐答案
我真的不明白的要求,但我认为功能应该做的唯一一件事就是打印ID的所有检查在TextBox的复选框。
I really don't understand that requirement but i think the only thing the function should do is to print the ID's of all checked CheckBoxes in a TextBox.
为什么这么复杂吧,这也工作:
Why do you complicated it, this works too:
TextBox1.Text = String.Empty
For Each control As Control In form1.Controls
If TypeOf control Is CheckBox AndAlso DirectCast(control, CheckBox).Checked Then
TextBox1.Text &= control.ID & ","
End If
Next
'remove last comma'
If TextBox1.Text.Length <> 0 Then TextBox1.Text = TextBox1.Text.Substring(0, TextBox1.Text.Length - 1)
据有关订单的新信息,试试这个:
According to your new informations about the order, try this:
Protected Sub CheckedChanged(ByVal sender As Object, ByVal e As EventArgs)
Dim chk As CheckBox = DirectCast(sender, CheckBox)
Dim separator As Char = ","c
If TextBox1.Text.Length <> 0 Then
Dim allIIDs As New List(Of String)(TextBox1.Text.Split(separator))
allIIDs.Remove(chk.ID)
If chk.Checked Then
allIIDs.Add(chk.ID)
End If
TextBox1.Text = String.Empty
For Each id As String In allIIDs
TextBox1.Text &= id & separator
Next
TextBox1.Text = TextBox1.Text.Substring(0, TextBox1.Text.Length - 1)
Else
TextBox1.Text = chk.ID
End If
End Sub
要注册<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.checkbox.checkedchanged.aspx\"相对=nofollow>的CheckedChanged-事件上的复选框你必须添加以下的ASPX每一个复选框:
To register the CheckedChanged-Event on the CheckBoxes you have to add following on aspx for every Checkbox:
<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true" OnCheckedChanged="CheckedChanged" />
或者如果你是懒惰,要做到这一点在codebehind,加入Page_Init以下内容:
or if you are lazy and want to do that in Codebehind, add following in Page_Init:
Private Sub WebForm1_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
For Each control As Control In Me.form1.Controls
If TypeOf control Is CheckBox Then
Dim chk As CheckBox = DirectCast(control, CheckBox)
chk.AutoPostBack = True
AddHandler chk.CheckedChanged, AddressOf CheckedChanged
End If
Next
End Sub
