Hi all,

I am using one wpf combo box control and adding one static combo box item and one list to its ItemsSource

using CompositeCollection. Below are the code.

             

 
                   
                       
                           
                           
                       
                   

 

and i am also assigning one string list to CompositeCollection and it is working fine. But whenever i am adding new a item to the list and assinging updated list to CompositeCollection. At that time i am getting below error

"collection was modified enumeration operation may not execute"

Please help me out inupdating my CompositeCollection.

Thanks
