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?

VB

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

This is the service that populate the listbox

VB

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"

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

Solution 1

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:

C#

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

The item only showing item.toString which gives me the dataproperty and not the datavalue.

Solution 2

Try something like:

VB

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

Have a look at full detail with sample here[^].

I dont have the content. The listbox is bound to a data property called "District".

Dim item As Object

For Each item In Me.ListBox1.SelectedItems

Dim district as string = Me.ListBox1.SelectedValue
This will show for the first selected value I need the item. Why can't I used item.toString()?
