Hi,

Try the following code snippet to achieve your scenario.

JS:
<script type="text/javascript">
    function OnClientClick() {
        var listbox = $find("<%= lbEssenceDispo.ClientID %>");
        var items = listbox.get_selectedItems();
        for (var i = 0; i < items.length; i++) {
            //get the selected items here
            var selecteditem = items[i];
        }
    }
</script>

Hope this helps.

Regards,
Princy.

Hi,

I was not able the replicate the issue that you are facing. Following is the complete code which worked as expected at my end.

ASPX:
<telerik:RadListBox ID="lbEssenceDispo" runat="server" SelectionMode="Multiple">
    <Items>
        <telerik:RadListBoxItem Text="RadListBoxItem1" />
        <telerik:RadListBoxItem Text="RadListBoxItem2" />
        <telerik:RadListBoxItem Text="RadListBoxItem3" />
        <telerik:RadListBoxItem Text="RadListBoxItem4" />
        <telerik:RadListBoxItem Text="RadListBoxItem5" />
        <telerik:RadListBoxItem Text="RadListBoxItem6" />
        <telerik:RadListBoxItem Text="RadListBoxItem7" />
        <telerik:RadListBoxItem Text="RadListBoxItem8" />
        <telerik:RadListBoxItem Text="RadListBoxItem9" />
    </Items>
</telerik:RadListBox>
<asp:Button ID="Button1" runat="server" OnClientClick="OnClientClick(); return false;" />

JS:
<script type="text/javascript">
    function OnClientClick() {
        var listbox = $find("<%= lbEssenceDispo.ClientID %>");
        var items = listbox.get_selectedItems();
        for (var i = 0; i < items.length; i++) {
            //get the selected items here
            var selecteditem = items[i];
            alert(selecteditem.get_text());
        }
    }
</script>

Please provide your entire code if it doesn't help.

Regards,
Princy.
