keep web form dropdown list from changing

Question

In a vb.net 2012 web form application, there is a page that is only accessed by the administrators of the application.
There are 2 drop down list options for the user to select and one submit button. Basically one drop donw list is the language that is to be selected and the kind of letter that is to be generated. The letter is a 'template' generic letter that the administrator changes.
After the administrator hits the submit button, the template letter is changed in the database and one dropdown list shows the language that was selected. The problem is the kind of letter drop list does not stay and show what was selcted. The kind of letter drop down lists displays what the intitial drop down list looked like initially.

Thus would you show me how to keep is the kind of letter drop down list from changing once the user clicks the submit button?
