set_checked(true) not saving after postback

[yoomee kwon]

I have the checkbox items in the listbox.
When the item is inserted into the  listbox, I want the checkbox to be automatically checked to be true.
However during the postback, the checked value is false on the serverside. How can I retrieve the value set by the client side?

Here is my code.

<

 

script language="javascript" type="text/javascript">

 

 

function AddItems(strDay, strDate, strType1, strType2) {

 

 

var list = $find("<%= lstDFSummary.ClientID %>");

 

 

var items = list.get_items();

 

list.trackChanges();

 

var item = new Telerik.Web.UI.RadListBoxItem();

 

 

var item2 = new Telerik.Web.UI.RadListBoxItem();

 

item.set_text(strDay + " , " + strDate + " - " + strType1 + " " + "<%= strShowName %>");

 

item.set_checked(

true);

 

items.add(item);

 

 

 

 

list.commitChanges();

}

 

</

 

script>

Hello Yoomee,

I suggest you first add the item to the items collection of RadListBox and then set its checked state:

items.add(item);
item.set_checked(true);
