title: DataGroup TileLayout autoheight
body: <p>I have DataGroup with TileLayout. How to make datagroup resize accordingly to number of elements in datagroup?</p>
  
  <p>For example 1 have 1 row with 4 elements. Each element is 20 pixels tall. So I want my datagroup to be 20 pixels tall as well. If I have 7 elements which will be 2 rows I want my datagroup to be 40 pixels tall and so on.</p>
  
  <p>Right now for datagroup with 1 row is about 100px tall.</p>
