When adding subgrid views to a dashboard in the Unified Interface, it appears the 'Filter By' option is greyed out for columns. I am trying to see if there is a way, either through point-and-click, or customization, to enable filtering to these subgrid views without having to navigate to the full grid.
I have tried adding Read Only Grid and Editable Grid controls to the component, but neither of these options enable the 'Filter By' selection.
I have checked the documentation on using FormXML and tinkered with the FormXML Manager in XrmToolBox, but have so far come up empty handed. I do not see anything in the FormXML schema that would enable this, however there are a couple items (namely GridUIMode) in the schema that accept strings as values, however the schema does not tell me what values can be used or what the parameter does.
Is this something that could be achieved by a custom control on the dashboard? Is there another way to allow filtering individually on columns of subgrid views?
Thanks!
