item disappears when the transfer mode=copy

[Anjali]

Hi,

  I have two listboxes, On my left side of list boxes, I have some items, when i transfer the items to the right side listbox, I add two checkboxes before those items. Everything works fine when the transferMode = move, but when I changed the transferMode=Copy then when I move the item from the left listbox to the right listbox, the checkboxes appear in the right list box, but items don't appear.
I am not sure what am I doing wrong. below is my code

<td style="width:"10%" >
           ag: <br />
               <telerik:RadListBox runat="server" ID="RadListBox_Unselectedag" AutoPostBack="false"
               Width="120px" Height="200px"
               TransferToID="RadListBox_selectedag" AllowTransfer="true" TransferMode="Copy"
               AutoPostBackOnTransfer="true" SelectionMode="Multiple" AllowDelete="false" AllowReorder="false" ontransferred="RadListBox_Unselectedag_Transferred" >
           </telerik:RadListBox>
       </td>
       <td style="width:"2%">aselected <br />
           <telerik:RadListBox runat="server" ID="RadListBox_selectedag" AllowDelete="true" AllowReorder="false"
               AutoPostBack="false" SelectionMode="Multiple" Width="140px" Height="200px"    >
               <ItemTemplate>

                  <asp:CheckBox ID="chkAD" runat="server" />
                   <asp:CheckBox ID="chkAS" runat="server" />
                   <asp:Label ID="lblagSelected" runat="server" Text='<%# DataBinder.Eval(Container,"Text") %>'></asp:Label>
               </ItemTemplate>

           </telerik:RadListBox>

       </td>
       <td>

My code behind looks like this

protected void RadListBox_Unselectedag_Transferred(object sender, RadListBoxTransferredEventArgs e)
        {
            foreach (RadListBoxItem item in e.Items)
            {
                item.DataBind();
            }
        }

Hello Anjali,

The issue occurs, because you are using ItemTemplate into RadListBox control. Please review the attached project. In your scenario it is possible to use the property of the RadListBox, CheckBoxes="True".

Hi,

  The attached project does not have any checkboxes, I need two columns of checkboxes in my sourcelistbox. can you give me example that has two columns of checkboxes.

Thanks,

Anjali

I tried the code line by line, didn't work. I need two columns of checkboxes.

Hello Anjali,

I was able to reproduce your issue. Please review the attached project. Please bind the RadListBox on the right side when an item is transferred.
