problem with generate big list of elements in the pup up if mouse hover on particular cells of column

[Dian]

Hi,

I have tree list view, when user mouse hover on  particular cells of column, I want to generate a pup up to showing elements.It is working fine, but if there are so many elements in the pup up, it will crush and stop run anything.Can anyone help?   

<telerik:GridViewDataColumn  Header="Name" DataMemberBinding="{Binding Name, Converter={StaticResource InsensitiveRevConverter}}">
                      <telerik:GridViewDataColumn.CellTemplate>
                          <DataTemplate>
