title: GridView Customization
body: <p>I have a grid view with more than one control (ie. a DropDownList and a TextBox)</p>
  
  <p>How can I bind the DropDownList in the gridview and how do I insert an add button in the footer of the gridview</p>
  
  <p>I have found a few ways to do this but they are confusing and I am not sure about the performance of them.</p>
