title: Javascript or jQuery Gridview Filter
body: <p>I have an <strong>ASP.NET GridView</strong> and multiple <strong>ListBoxes</strong> as Departments, Categories, Faculties etc. ListBoxes and GridView are filled from a database (MSSQL) in codebehind. </p>
  
  <p>I need a <strong>JS</strong> or <strong>jQuery</strong> function that takes selected item's value and filters gridview rows by this value. <strong>For example</strong>, when a department selected from department listbox, it will show only the entries in that department (hide others). </p>
  
  <p>I know, it is not a proper question without sample codes but i really need some hints in this case. </p>
  
  <p>Thanks for help. </p>
