Custom Visual: Slicer selection display won't stay when page changes. (Visuals will reload)

Hi there,

 

I developed a timeline slicer. Everything works fine except that I realised the selection display won't stay when I shifted page. I know when page changes, the visual will automatically reload and hence runs the constructor and reset the visual to default state. How can I prevent the reload or set the constructor to reload the previous status? Is it the workaround something to do with bookmarking? Ken

Hi,

 

You are right, you can restore filter from update options.

If you use API 2.2 or higher, you will be able to read property jsonFilters from Options parameter inside Update method.

Hi,

 

How do you pick the data in the slicer, through a Selction mechanism or Filter API?

If you work with a slicer it is recommended to use the second option.

Also, every time when you change the size of a visual, the Constructor woun't be called, only Update method will be.

Hi Evgenii,

I use Filter API. So I have no problem with the filter even though the page changes and the visual reload, the data is still filtered. However, the visual needs to display which is filtered. When page changes or the dashboard refresh, I think the visual will reload and the Constructor will be called. I believe something must be done in the Constructor to call back my previous status.
