Get Display Option Value

s there any way at controller level or view level to get the selected displayoption for a specific block?

I have looked into a custom content area renderer, and while I can grab it at this stage if I try and add it to viewdata or the viewbag by the time it gets to the razor view the viewdata/viewbag has been cleared.

I have also looked into using OnTemplateResolved but at this point I don't think you have access to the selected display option.

Thanks

You wanted to get it from block's controller?

scope for the display option for the block is tight to that specific block instance while it's rendered (because you might have 2 blocks on the area each with different display options). Here you can read up a bit on the problem bootstrap renderer had - https://github.com/valdisiljuconoks/EPiBootstrapArea/blob/master/src/EPiBootstrapArea/BootstrapAwareContentAreaRenderer.cs#L121

Scott, let me find issue in bootstrap renderer as I recall that tag was conflicting with display options back in days when I hacked together bootstrap lib

Yes, 'tag' is overwritten by the selected display option, even if the display option doesn't have a tag. I reported this as a feature request a while ago - to not overwrite the tag if the display option doesn't have one.

But question is if JSpencer wants the tag or the actual display option, since they might not be the same?

Display option will have the tag in definition so you just look it up against the defined display options to get the option. That's what I've done in the past.
