title: Kendo UI Grid with Cascading DropDownList
body: <p>I have a Kendo UI Grid on my Razor Layout which fetches data from the controller.</p>
  
  <p>In this grid I wish to have a set of 3 DropDownLists which are:</p>
  
  <p><code>ProductGroups</code>, <code>Products</code>, <code>Services</code></p>
  
  <p>The behaviour I wish to implement is, when I Add a row to the Grid, I choose <code>ProductGroups</code> first, and the <code>Products</code> DropDown is updated with products list filtered by <code>GroupId</code> (value).  Then select <code>Product</code> and like the first one, update the <code>Services</code> DropDown with services filtered by <code>productId</code> (value).</p>
  
  <p>I don't quite know how to achieve this, can anyone please help me?</p>
  
  <p>Thank you all for your help.</p>
  
  <p>Best Regards.</p>
