Custom Visual with drill support

How can I implement a custom Power BI visualization that supports the new drill down functionality? Specific interfaces/properties/attributes that needs to be supported?

    I have not tried this in the Playground yet, but numerous charts have drilldown listed in their Capabilities. Try using one of the [x]capabilities.ts files for a template.

     

    For example:

    drilldown: {
                roles: ['Category']
            },

Hi,

 

I have a data set with two hierarchical columns as REGION and SUB-REGION. A REGION has multiple SUB-REGION'S.

 

I have dragged both the columns to VISUAL FILTER section in Power BI.

 

When I select a REGION and then SUB-REGION in the visual filter, I am not getting the selected "SUB-REGION" in the "update" method of Custom Visual.

 

Is there anyway to get both the REGION and SUB-REGION whenever filter is modified?

Could you help on this. Thanks in advance.

Hi,

 

If I understand you correctly I don't think there is any way of getting data from more than one drill-down level at a time. You will always get data on the current level only (at least the last time I tried it). This makes is very hard to create custom visuals that display hierarchies using drill-down (such as Pivot Tables or Breakdown Trees). Hopefully this will be supported in the future.

    Thanks. Could you suggest any reference for adding a field to capabilities with drill down option in custom visual.

     

    Thanks
