禁用复选框选择在VB .NET 2008 Winform的列表视图 [英] Disabling checkbox selections in VB .NET 2008 Winform Listview

问题描述

你如何禁用其他复选框选项/ deselections不牺牲ListView控件的功能？我知道你可以拨打：ListView.Enabled =假，但也禁用其中的任何滚动

How do you disable additional checkbox selections/deselections without sacrificing the functionality of the ListView? I know you can call: ListView.Enabled = False, but that also disables any scrolling within it.

例如：我有一个启动的基础上被选中的列表视图项的备份计时器。过了一段时间，我不想让最终用户能够在列表视图中点击任何复选框（所以我有项目的备份集数），但我希望他们能够滚动而正在执行列表中的备份。我想这样的：

For example: I have a timer that starts a backup based on the Listview items that are checked. After a certain time, I don't want the end-user to be able to click on any of the checkboxes within the listview (so I have a set number of items to backup), but I do want them to be able to scroll the list while the backup is being performed. I tried this:

Private Sub clboxOptions_ItemChecked(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ItemCheckedEventArgs) Handles clboxOptions.ItemChecked

If backupStarted = True Then
   If e.Item.Checked = True Then
      e.Item.Checked = False
   Else
      e.Item.Checked = True
End If

不过，这似乎并没有为我工作。 谢谢！ JFV

But this doesn't seem to work for me. Thanks! JFV

推荐答案

我发现了什么我的问题是。我用的是ItemChecked的而不是ItemCheck的方法。下面code对我的作品：

I found out what my issue was. I was using the 'ItemChecked' instead of the 'ItemCheck' Method. The below code works for me:

Private Sub clboxOptions_ItemCheck(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles clboxOptions.ItemCheck
    Try
        If backupStarted = True Then
            If e.CurrentValue <> e.NewValue Then
                e.NewValue = e.CurrentValue
            Else
                e.NewValue = e.NewValue
            End If
        End If
End Sub
