The data is displayed in my nested grid (binds to the main grid's collection property) inside the main grid's editor template. But when I try to add/update the data the editor template is found but not displayed correctly. For some reason it just shows 0 instead of the editor template content. What could be the problem here?
p.s. Found this on the forum:
When you are trying to load a helper that will contain templates in another template (in this case the Popup template of the main Grid), you need to ensure that you are calling the ToClientTemplate method over the nested helpers. This should resolve the escaping in the templates and it should resolve the problem that you are facing
So I've added ToClientTemplate() to my nested grid & tried adding it to the helpers inside the nested grid's popup editor but this changes nothing,the problem is the same.
