KB320020: Automatically Trigger the "Add Existing Dataset" Panel When a New Visual Insight Dashboard Is Created using MicroStrategy SDK 10.5

SUMMARY:
A developer may need to know the number of datasets within a Visual Insight Dashboard.  One use case is to determine if a Visual Insight Dashboard is new.  Assuming that a new Dashboard will contain 0 datasets, developers can insert logic to enable panels such as the "Add Existing Dataset" panel when a Dashboard has 0 datasets.  
 
CUSTOMIZATION SUMMARY:
To achieve this customization, developers can leverage JavaScript and the Strategy SDK.  The following JavaScript snippet will return 0 if no datasets are attached to the current Visual Insight Dashboard: 

Object.keys(mstrApp.rootCtrl.view.controller.datasetsPanel.data).length

This JavaScript snippet returns the number of datasets already added to this Strategy Visual Insight Dashboard.
The following JavaScript snippet will trigger the "add existing dataset" panel when executed on the Strategy Visual Insight page (Html5Vi):

mstrApp.rootCtrl.view.controller.docCtrl.addDataset()

 
CUSTOMIZATION STEPS:

1. Launch the Strategy Web Customization Editor
2. Create a new plugin, give a meaningful name
3. Navigate to Strategy Web Configuration-> Pages -> Html5Vi(HTML5 VI Page) -> JavaScript.
4. Right-click on the JavaScript folder and choose "Create New Javascript".
5. Use the following snippet:
   

   
   if(Object.keys(mstrApp.rootCtrl.view.controller.datasetsPanel.data).length == 0){
   	console.log("Dashboard doesn't seem to have existin datasets, since count is 0. Triggering logic to prompt user to add existing dataset");
   	mstrApp.rootCtrl.view.controller.docCtrl.addDataset();
   }

   
   
6. Save the JavaScript, restart Strategy Web and clear browser caches to apply the customization.
