Hello Christian,

Internally the row template was implemented as a gateway for the column templates. Thus we had to parse the row template string and split it by columns. This approach proved to be slow and error prone, that's why we decided to get rid of it. As a result we gained around 30% faster rendering (columns which don't need templating do not need to go through the templating code anymore, which was the case when using row templates).

Hope this helps,

Hello Christian,

As of 14., the RowTemplate option of the igGrid has been deprecated. The individual column templates can be used instead for applying templates in the grid:
