获取复选框的值在CheckBoxList控件 [英] getting the values of checkboxes in a checkboxlist control

问题描述

我有一个asp：我的网页上的CheckBoxList，我需要得到选中的复选框的值

I have an asp:CheckboxList on my page and I need to get the values of the checked checkboxes.

所以，我有那么遍历，但是我发现没有办法来检索与个人复选框相关的值LINQ查询。

So I have a linq query that I then loop through, but I've discovered that there is no way to retrieve the values associated with the individual checkboxes.

下面是我的code：

        Dim checkboxValues = cblmyCheckboxes.Controls.OfType(Of CheckBox)().Where(Function(c) c.Checked)

        For Each c As CheckBox In checkboxValues
            Response.Write(c.Value)
        Next

我怎样才能获得价值？

How can I get the values?

感谢

推荐答案

您复选框列表中包含列表项，而不是复选框。所以cblmyCheckboxes.Items是 ListItemCollection

Your Checkbox List contains ListItem and not checkbox. So cblmyCheckboxes.Items is a ListItemCollection

真的，更快，更简单的方法是：

Really, a quicker and easier way would be:

For Each li as ListItem in cblmyCheckboxes.Items
       If (li.Selected) Then
           Dim XX = li.Value
          '' Do something with Value
       End If
Next

使用LINQ你有效​​地通过复选框循环列出的项目（在你的LINQ功能的背景（这是错误反正），然后又在对于每个 - 还不如干脆做一个...

By using LINQ you're effectively looping through the checkbox lists items (in the background of your LINQ function (which is wrong anyway) and then also looping again in your For Each - might as well just do the one...
