I am generally used to get values from database in sorted order. Here I am required to sort the data from an xml file 
so that the values are displayed in ascending order in the combobox. 

I thaught of writing code to do the same. found a very simple solution. 

Open properties set softed  = true 

or 

cbPrebuilt.Sorted = True


cbPerbiilt is the combobox in the winform i wanted sorted.
