title: How to display selected data from dropdownlist in grid view?
body: <p>I have a <code>dropdownlist</code> in which I want to show different branches of a college.</p>
  
  <p>When a user selects one of the value from the <code>dropdownlist</code> then the data corresponding to that value has to be displayed in the grid view.</p>
  
  <p>For example when a user selects "information technology" from drop-down list box then list of faculty members related to information technology has to be displayed in grid view.  </p>
