title: XCeed DataGrid for WPF v4.x: Accessing Excel like filters
body: <p>I am using XCeed DataGrid for WPF 4.x. I have created excel like drop down filters using <strong>view's ItemProperties</strong>.</p>
  
  <ol>
  <li>Let’s say there is a single column in data grid with values 1,1,0,1. </li>
  <li>Now I apply excel like filter
  <img src="https://i.stack.imgur.com/EmG80.png" alt="enter image description here"></li>
  <li>Now there will be rows with value 1 in the data grid.</li>
  <li><strong>Question:</strong> How to find values checked in this drop down<code>(read)</code>? And also how to set these check boxes from code behind<code>(write)</code>?</li>
  </ol>
  
  <blockquote>
    <p><strong>Main purpose:</strong> To retain previous excel like filter applied by user when data grid item source is changed.
    <em>[In case of above example after #2, if I change items source from {1,1,0,1} to {0,0,0,0} then user should not be able to see even a single row in grid]</em></p>
