Hello,

I am not sure if this feature is supported - I will double check with the dev team and let you know (I also tried several scenarios and none of them worked for templated columns). This may be logical to some point, since templates can contain anything including complex server-side controls, so maybe the exported cannot be that clever to export that.

I have a suggestion though - for exporting data, you can create a new datasource with one extra column / field that you can construct with code and could be what the templated column showed (or a simplified text version of it, if it contains server controls)
