    callum,

Hi callum v-chuncz-msft
I'm also trying to develop a custom visual and is stuck at this particular point.
how did you retrieve property values from the dataview and how did you populate the property pane afterwards?
Did you use enumerateObjectInstances ?

    Hello Anonymous

     

    Yes, you should implement enumerateObjectInstances in order to update values at the format panel.

    Do you have VisualSettings class in your csutom visual?

      hello v-viig
      Yes,I am using VisualSettings class.
      Should i use the switch statement then.
      I'm a little confused as this template is slightly different from the one in the tutorial.

        If you want to include new properties into formatting panel you should:

        • Create a new class

         

        export class NewGroup {
    public show: boolean = true;
}
        • Specify an instance of the new class into VisualSettings class

         

        export class VisualSettings extends DataViewObjectsParser {
  public newGroup: NewGroup = new NewGroup();
}
        • Specify the new group at capabilities.json
        "objects": {
    "newGroup": {
        "displayName": "New Group",
        "properties": {
            "show": {
                "displayName": "Show",
                "type": {
                    "bool": true
                }
            }
        }
    }
}

        Please note that these steps are for including the new group of properties. You can actually include new properties into the existing classes (please don't forget to specify the same properties at capabilities.json).

         

        Please let me know if you have any further questions.
