  <pre><code>&lt;Grid.ColumnDefinitions&gt;
     &lt;ColumnDefinition Width="auto" SharedSizeGroup="SG1"/&gt;
     &lt;ColumnDefinition Width="auto" SharedSizeGroup="SG2"/&gt;
  &lt;/Grid.ColumnDefinitions&gt;
  </code></pre>
  
  <p>every time?</p>
  
  <p>Thank you very much!</p>
  
  <p>ps: I did try to search on Google first. But I couldn't find any answer. Anyone who find the answer from google could you please tell me what keyword do you use to search? Sometimes I find it hard to determine what keyword use to search.</p>
  
  <p>ps2: I am too lazy, every I just open chrome and type something and search. If nothing found, I conclude nothing found and come here. Is there anyone will search on Google, then find nothing, then open bing.com and search? And find nothing and go to yahoo and search and search?.....</p>
