Hi, I have exactly the same problem. I even have just one object ( not an array) I want to transfer that way to another page. I doesn't work. I even got a java.lang.ClassCastException as I try to convert an Object back to the specific object I use.
I believe this is a bug or the tutorial is just wrong stating, that you can wrap any object. I even tried using Objects for everything and then casting them back. But it just gives me the java.lang.ClassCastException.
Can anyone from the Creator Team address this?

Get selected values from Listbox control

Hi All,
I'm still new to SL so please bear with me.
I have a ListBox being bound with some records from a DB. Here's the xaml:
<ListBox x:Name="lstClassSeries" SelectionMode="Multiple" DisplayMemberPath="Description" Grid.Row="11" Grid.Column="1"></ListBox>
What I need is to get the values of the items that were selected and I can't seem to get it to work. I've tried looping through the SelectedItems but there's no property for value or text. I even tried to cast the item as a ListBoxItem but I
get the following error:
Unable to cast object of type 'UI.Silverlight.TransactionService.DTODropDown' to type 'System.Windows.Controls.ListBoxItem'.
How can I get the values of the items selected?
Thanks

You're using windows forms style techniques with xaml.
This is a bad idea.
You ought to learn MVVM.
You probably don't think you want to learn it, but trust me on this one.
Learn MVVM as soon as you can.
There's a selecteditems collection.
You have to cast to listboxitem, it has a content property which you cast to whatever you put in there originally.
Here's a snippet.
I have a class foo, load a bunch of them in. Do stuff. Work out what's selected in the click event of a button.
public class foo
public int id {get;set;}
public string description {get;set;}
public partial class MainPage : UserControl
public MainPage()
InitializeComponent();
lb.Items.Add(new ListBoxItem{Content=new foo{ id=1, description="a"}});
lb.Items.Add(new ListBoxItem { Content = new foo { id = 2, description = "b" } });
lb.Items.Add(new ListBoxItem { Content = new foo { id = 3, description = "c" } });
private void Button_Click(object sender, RoutedEventArgs e)
List<foo> selectedfoos = lb.SelectedItems.Cast<ListBoxItem>().Select(x=>x.Content as foo).ToList();
Hope that helps.

How can i add to a listBox items near in a new column other items ?

The items on the right i changed the property of the listBox1 righttoleft to Yes.
My problem is i want to build a new column for the number so each number i'm adding will be next on the left to the belong item string. And not under it like now.
1. Maybe i need to use another control and not listBox ?
2. How can i add column/s and also maybe adding a title to each column like: Names Id Number....?

If you want columns, you should consider a
ListView or
DataGridView.

Goto field and listbox color formats

i've got two questions
1. i've scripted a functional listbox (field2) that hides or shows fields depending on options selected ('yes' opens field2a, 'no' hides field2a) but depending the option chosen i want to 'go to' an appropriate field. example: 'yes' automatically goes to field2a, 'no' proceeds to field3
as it is the 'yes' jumps to field3 and 'no' goes back to the top of the page. is there a command/script i can enter at the end of the 'if' and 'or' statement that will place the cursor in a designated field?
2. the list box only shows as white text on a blue background. is there a way to make it show like a regular text box (black text on a white background)?
any help is greatly appreciated!!
..joseph g

You are sure you are getting only "No" and "Yes" from your list box?
$host.messageBox(Concat("Event value = ", event.vlaue), "Verify Event Value", 3, 1);
if (event.value=="No") {
this.getField("5S1").hidden = true;
xfa.host.setFocus("8");
}else {
if (event.value=="Yes") {
this.getField("5S1").hidden = false;
xfa.host.setFocus("5S1") };
Are your 2 fields are not in the same section, you will need to provide the full reference.

Select all in listbox

Hi guys,
I have a question.
I have a from xml populated listbox and want to select by pushing a button all populated items in the list.
this is my code.
the interesting thing is, that this code works before I import xml data, but as soon as i import xml data, it doesnt work anymore.
Do you have any idea, what the problem is and how can I fix it?
and second question. Is it possible deselect single items, when all are selected?
var temp1 = "";
for (i=0;i< PAGE3.ListBox1.length.rawValue;i++){
temp1 = temp1 + ListBox1.getDisplayItem(i) + "\n";
ListBox1.rawValue = temp1
Thank you in advance for any help!!
Diana

The code should work as long as you set "Allow Multiple Selection" at design time.
However I will suggest small change to your code...try the following...
var temp1 = "";
for (i=0;i< PAGE3.ListBox1.length;i++){
temp1 = temp1 + ListBox1.getDisplayItem(i) + "\n";
ListBox1.rawValue = temp1
Hold "Ctrl" btn for deselcting from the list.

    }any idea or suggestion tell me

You usually use the property behind value="#{DynamicListBean.selectedCategory1}" for that. But in your case you'll need the vce.getNewValue() as the valueChangeListener is been invoked before the property is been set.
Having said that, your code is terrible. Please read on about the DAO pattern. Further on, did you know that you can also just use List<SelectItem> instead of SelectItem[] as f:selectItems value?

Retrieve Values From ListBox

Hi,
I have a ListBox populated with values. The user can select multiple values. One of the values is "OTHER". If this is selected (alone or amongst multiple selections) a text field should be turned from read only to open.
So far I can do this only when the OTHER value is selected by itself. How can I modify my current script to accommodate for multiple selections?
Current JavaScript:
if (this.rawValue == "OTHER - Please Specify")
PO.main.Subform5.OtherRegion.rawValue = "-->SPECIFY<--";
PO.main.Subform5.OtherRegion.access = "open";
else
PO.main.Subform5.OtherRegion.rawValue = "------";
PO.main.Subform5.OtherRegion.access = "readOnly";
Thanks

Try something like this
<select size="1" name="tst" tabindex="3">
<option value="item1">item1</option>
<option value="item2">item2</option>
<option value="item3">item3</option>
</select>
then in the response
<%
String result = request.getParameter("tst");
out.println("You selected: " + result);
%>
I haven't tested this out, but I believe something like this should work

How to get the selected items from listbox

Regarding listbox i have two questions
1) I want to get the selected items as per the order in which ihave selected.Presently i'm getting in the ascending order.For example after selcting the 1,2,6 if i select 3 then its giving 1,2,3,6.But i want it in the order 1,2,6,3
2)I want to select items from a single list box to many other listboxes.(ie) my first selection should goto first,second one to the second listbox and like this.How should i write the logic.
please give me a suggestion.

In order to have the selected items line up in accordance to the selection order, please do it one at a time. (That's the limit for that VI)
If you need more than that (i.e. to regconize which item clicked first and which one comes later), you may have to figure it out ya
Wish you good luck. Perhaps, someone else has a already made vi.
Cheers!

How to get selected value from a listbox

Hi !
I use following code to fill in my LISTBOX with values :
AT SELECTION-SCREEN OUTPUT.
val-key = 1.
val-text = '0016'.
APPEND val TO list_values.
val-key = 2.
val-text = '0028'.
APPEND val TO list_values.
val-key = 3.
val-text = '0035'.
APPEND val TO list_values.
val-key = 4.
val-text = '2001'.
APPEND val TO list_values.
val-key = 5.
val-text = '0515'.
APPEND val TO list_values.
CALL FUNCTION 'VRM_SET_VALUES'
    EXPORTING id     = 'p_list'
              values = list_values.
My question is - how to get a selected key/text value ? i dont need it to be done dynamically - i just need it in START OF SELECTION to perform tasks.
Thx in advance.

Unfortunetly it does not work
i Define parameter as follows :
PARAMETERS:
p_list AS LISTBOX VISIBLE LENGTH 10.
Then i add values to it :
AT SELECTION-SCREEN OUTPUT.
val-key = 1.
val-text = '0016'.
APPEND val TO list_values.
val-key = 2.
val-text = '0028'.
APPEND val TO list_values.
val-key = 3.
val-text = '0035'.
APPEND val TO list_values.
val-key = 4.
val-text = '2001'.
APPEND val TO list_values.
val-key = 5.
val-text = '0515'.
APPEND val TO list_values.
CALL FUNCTION 'VRM_SET_VALUES'
    EXPORTING id     = 'p_list'
              values = list_values.
Then when i add a blank section :
AT SELECTION-SCREEN ON p_list.
I set a breakpoint in START OF SELECTION block - but the value is empty no matter what do i select.
Actually when i select value from the list and hit enter key on selection screen the selection in a listbox goes empty :/
Whats the cause of this ?
