Either use the Form Loader widget in your template grid (this is not the preferred solution), or use the new List View instead of the template grid. The drawback to this is that you cannot have multiple records on each row
@Mendix: Are you guys working on a permanent solution for this issue? This feature is needed in all application and the current solutions are dirty workaround
Please make the Template Grid Editable!
Ported The form loader to Mx5 (Its not fully functional but good enough for the template grid) https://forum.mendix.com/questions/5813/FormLoader%20for%20Mendix%205#9228
I now use the list view editable; that results in a better user experience
Isn't your template grid inside a view which has editable set to no?
