Thanks for the solution, it worked for me.
Can you please explain why it works when a desktop folder is created in the above mentioned paths?

Thank you for your solution.

sorry i gave wrong example. I have many value items and one "By Rule" which is will opens the window and this combo box is inside a grid view cell.

Thank for quick response.

Actually my scenario is ,
1) I have combobox which contains two items "value" and "By Rule".
2) Whenever user selects "By Rule" it will open new window, and i will perform some operations in that window.
3) The data related to those operations will get saved in xml then the window gets closed.
4) If i changed the selected item to "value" in combobox the data in xml will be deleted.
5)So, without deleting the data in the xml i need to open the window again by selecting the combobox item "By Rule" which will show the saved data.

I tried to add button so that if the combobox item is "By Rule" i will click button it will open the window with previous data but user is not agreed to it.

Now i need the way to trigger the window whenever i selected "By Rule".
