Hello Dhamu,

In order to preserve the changes after postback you need to call trackChanges and commitChanges.
Aspx:

<telerik:RadListBox ID="RadListBox2" CssClass="Large" runat="server" EnableDragAndDrop="true"
            AllowTransfer="true" ButtonSettings-ShowDelete="true">
 <Items>
      <telerik:RadListBoxItem Text="Argentina" />
      <telerik:RadListBoxItem Text="Australia" />
      <telerik:RadListBoxItem Text="Brazil" Selected="true" />
      <telerik:RadListBoxItem Text="Canada" />
      <telerik:RadListBoxItem Text="Chile" />
      <telerik:RadListBoxItem Text="China" />
</Items>
</telerik:RadListBox>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
<asp:Button ID="Button2" runat="server" Text="Disable form client side" OnClientClick="disable();" />

C#:

protected void Button1_Click(object sender, EventArgs e)
    {
     RadListBoxItem item=RadListBox2.FindItemByText("Canada");
     item.Enabled = false;
    }

Javascript:

function disable()
  {
       var listBox = $find('<%= RadListBox2.ClientID%>');
       listBox.trackChanges();
       listBox.findItemByValue("Canada").set_enabled(true);
       listBox.commitChanges();
   }

Thanks,
Shinu.
