In IE8 Reordering same item by drag and drop more than once throwing script error.

[Praveen]

In IE8 when I do drag and drop item for first time it drops. Again if I drag and drop same item it throws script error.
Below is my RadListBox code:

 <telerik:RadListBox ID="rlbId"
                                                runat="server" 
                                                AllowReorder="true" 
                                                ShowReorder="false" 
                                                EnableDragAndDrop="true"
                                                Width="375px" 
                                                Height="400px" 
                                                SelectionMode="Single">
                                                <ButtonSettings Position="Right" VerticalAlign="Top" />  
                                           <ItemTemplate>
                                                    <table class="bottomBorder" style="border-collapse: collapse; width: 100%;">
                                                        <tr>
                                                            <td style="width: 30%; border-bottom: 1px solid black; padding: 5px; text-align: left;"><%# Eval("Code")%></td>
                                                            <td style="width: 30%; border-bottom: 1px solid black; padding: 5px; text-align: left;" align="left"><%# Eval("Name")%></td>
                                                        </tr>
                                                    </table>
                                           </ItemTemplate>
                            </telerik:RadListBox>

Hello Praveen,

I was able to replicate the described exception, which is thrown using the demonstrated implementation. I had forwarded it to our developer team for further consideration. However, I am afraid that the scenario you had implemented is not valid. When you are using the Server ItemTemplcate, an AutoPostBackOnReorder should be set to true, in order to ensure the correct reorder of the Items. You could encapsulate the RadListBox in an RadAjaxPanel , like demonstrated in this online demo.

Another possible approach is to use the ClientItemTemplate, where AutoPostBackOnReorder  does not need to be set. I have prepared a sample page for you, demonstrating a possible implementation, using the ClientItemTemplate. Please find it attached.
