每个选定项目的Silverlight ListBox [英] Silverlight ListBox for each selected item

问题描述

我知道这听起来很愚蠢，但花了我几个小时却无法正确解决.
如何从Silverlight列表框中获取selecteditem?

I know this may sound silly but took me a few hours and couldn''t get it right.
How to get selecteditem from the silverlight listbox?

Dim item As Object
For Each item In Me.ListBox1.SelectedItems
//here i just could not do it.
Next

这是填充列表框的服务

This is the service that populate the listbox

Dim proxy As New ...()
AddHandler proxy.GetDistrictCompleted, AddressOf Proxy_GetDistrictCompleted
proxy.GetDistrictAsync()

Me.ListBox1.ItemsSource = e.Result
Me.ListBox1.DisplayMemberPath = "District"
Me.ListBox1.SelectedValuePath = "District"

我知道从ASP内向外，但silverlight似乎有所不同.

I know inside out on the asp but silverlight seems to be different.

推荐答案

只需将item 强制转换为您的特定数据类类型.

我不确定为此使用VB语法，但是在C#中，您可以这样做:

Just cast item to your specific data class type.

I am not sure of the VB syntax for this, but in C# you''d do this:

MyType myType = (MyType)item;
DoStuff(myType.MyProperty, etc...);

尝试类似的方法:

Try something like:

Dim lbi As ListBoxItem = TryCast(TryCast(sender, ListBox).SelectedItem, ListBoxItem)
textBlock1.Text = " You selected " + lbi.Content.ToString() + "."
