Filtering a lookup column value of dxdatagrid
<p>I am working with a devextreme mobile application, and I am not able to implement filter in one of my lookup column.</p>

<p>I want to filter lookup value based on my column data. For example: If my lookup column contains values like:</p>

<pre><code>CEO,
Executive,
developer
</code></pre>

<p>Then while inserting a new row the look up should not contain these values .
I have attached a sample fiddler for better understanding. </p>
