在DevExpress CheckedComboBoxEdit中获取检查项目

问题描述

我正在使用DevExpress 9.3 CheckedComboBoxEdit，我需要获取所有已检查项目的集合。似乎这应该是一个简单的任务，但是我找到的最接近的一个解决方案是我可以使用的东西：

  CheckedComboBoxEdit.Properties.GetItems.GetCheckedValues（）
  

不幸的是，这里没有GetCheckedValues方法。我已经找到以下内容：

  CheckedComboBoxEdit.Properties.GetCheckedItems（）
  pre> 
 
 
它返回一个对象，但我找不到任何关于我应该将对象转换为的引用。我还试图迭代这些项目，并检查每个项目是否检查，按照，但Items返回一个字符串的集合，而不是CheckedListBoxItem，所以我无法测试是否被检查。
 
 
 
我想要什么是已检查项目的String集合;现在，我可以收到他们作为任何类型的收藏，甚至自己创建收藏。我知道我会忽略一些非常简单的事情，但我似乎找不到。
 
 
 
 解决方案 
 
 
 
这是我想出的解决方案。我更喜欢更优雅的东西似乎应该有一种方式来获得检查的项目，因为这是控件的。然而，这似乎是有效的：
 私有函数GetChecked（）作为列表（String）
 Dim List（Of String）
 Dim checkedString As String = CType（SitePickerControl.Properties.GetCheckedItems（），String）
 If（checkedString.Length> 0）然后
 checked.AddRange（checkedString。拆分（新的Char（）{，c}））
结束If 
返回检查
结束函数
  
如果有人可以给我一个正确的解决方案，我很乐意看到。
解决方案
 p>这是我使用的：
  var ids =（来自checkedComboBoxEdit.Properties中的CheckedListBoxItem项.Items 
其中item.CheckState == CheckState.Checked 
 select（int）item.Value）.ToArray（）; 
  
您还可以在 CheckedListBoxItem  
 
 
 
（它是C＃，而不是VB，但概念是一样的。）
 
I am using the DevExpress 9.3 CheckedComboBoxEdit, and I need to get the collection of all checked items. It seems like this should be a simple task, but the closest thing I have found to a solution is something that says I can use:
CheckedComboBoxEdit.Properties.GetItems.GetCheckedValues()
Unfortunately, there is no GetCheckedValues method here. I have found the following:
CheckedComboBoxEdit.Properties.GetCheckedItems()
which returns an object, but I cannot find any reference on what I should cast the object as. I have also tried to iterate through the items, and check each one to see if it is checked, following the suggestion from here, but Items returns a collection of Strings, not CheckedListBoxItem, so I cannot test if they are checked.
What I want is a String collection of checked items; right now, I am okay to receive them as any type of collection, or even create the collection myself. I know there must be some very simple thing that I am overlooking, but I can't seem to find it.
SOLUTION
This is the solution that I came up with. I would prefer something more elegant; it seems like there should be a way to get the checked items, since this is what the control is for. Nevertheless, this seems to work:
Private Function GetChecked() As List(Of String)
    Dim checked As New List(Of String)
    Dim checkedString As String = CType(SitePickerControl.Properties.GetCheckedItems(), String)
    If (checkedString.Length > 0) Then
        checked.AddRange(checkedString.Split(New Char() {","c}))
    End If
    Return checked
End Function
If anyone can give me a proper solution, I would love to see it.
 解决方案 
This is what I use:
var ids = (from CheckedListBoxItem item in checkedComboBoxEdit.Properties.Items
           where item.CheckState == CheckState.Checked
           select (int)item.Value).ToArray();
You can also make an extension method on CheckedListBoxItem which will return only checked items values.
(It's C#, not VB, but the concept is the same.)
