  Is there a way where I can selectively render showDropDowns in individual cell instead of the entire column. I have a grid with more than 52 columns and more than 40 of these 52 will require dropdown combobox. If showDorpDown is enabled, the page looks too crowded with arrow all over places. If I can enable showDropDown on a single cell when it is selected/gotFocus, that will make the page look much cleaner. Thank you very much.

  Below is some examples of what I see how showDropDown are enabled.

  You will need to render all the DropDown though but you can set the Visible Property on the DataMap for these cells using the item formatter and therefore only DataMap only when clicked and hide when then are out of focus. Please note that using ItemFormatter has a computation cost as it would need to run for all cells in the grid and it may lead to Performance issues.

  Let me know if you are still facing issues.

  Thanks,

  Hi Hoang,
  
  Here is the demo sample(http://jsfiddle.net/mkgupta911/8brL80r8/58/) for the same, but it will increase performance issue since itemFormatter will trigger each time.
