title: Cascading Combo Boxes in the Filter row of a DevExpress Aspx Gridview
body: <p>Throughout my ASP.net application I employee the 'cascading combo boxes' technique as depicted below.  </p>

  <p>For anyone not familiar with the term, cascading combo boxes is a technique where the datasource of one combo box is bound to the datasource of another.  For example in the image above, the 'Sport' combobox choices changes based on the input of the 'Sport Category' combo box likewise, the Keyword combobox choices change based on what the user selects in the 'Sport combo box'.</p>
  
  <p>What I want to know is if there is any way to acomplish this same technique in the filter rows of the DevExpress suite's AspxGridview contorl and if so can anyone show or point me to some examples of how to acomplish this. </p>
