how to check if grid field is empty

Question

I just need to check if one field artist_gallery:image in a grid field is set, if not the markup should not be rendered. This syntax {if "{artist_gallery:total_rows}” > 0} or {if artist_gallery:total_rows > 0} is not working ... if there is no image, the markup is rendered.

Any ideas? Thank you!

    {if "{artist_gallery:total_rows}" > 0}
 <div id="artistgallery">
  <div class="cycle-slideshow">
   {artist_gallery}
    <img src="{artist_gallery:image}">
   {/artist_gallery}
  </div>
  <div id="adv-custom-pager" ></div>
  <div class="clb"></div>
 </div>
{/if} 

Answer 1

Try

{if my_grid_field}
    {my_grid_field}
        Stuff in here if the grid field has rows
    {/my_grid_field}
{/if}

I've now discovered that it is a bug in 2.9.2 and there is a fix, see this question and the answers: Grid Conditionals not working
