    Hi Sergey_Skalyga,

    In the future, if you have a question specificially about the WebDocumentExporter, you can post it in that forum.

    I tried out your little sample and got the same results.  What happens is that for templated cells, we attempt to render the template out as a string.  If we get an exception doing that, we return an empty string.  That is what is actually happening in this case because the checkbox has a runat attribute, so it needs to render in a form, not outside.  I tried a simple item template like <span>two</span> and it renders excactly that string out.  So, what you can do is handle cell exporting and set the value to true or false and it would at least say that.  Or you could add an image of a checked/unchecked checkbox to the cell.  In 11.1, there will be a bound checkbox that will automatically export the checked/unchecked/partial image.

    regards,
