dynamics-crm - How to add a custom button on CRM subgrid?

Question

I have two entities in my Dynamics CRM solution. Both are related to each other. Product -> configurations

Each product can have multiple configurations. I have added a subgrid on product screen.

I need to call a custom html webresource to be able to create configuration records.

How to add a custom button to the subgrid? OR how to customize existing (+) button to open an html webresource?

Answer 1

1. Add the entity to a solution & take a backup
2. Open the solution in Ribbon workbench
3. Start customizing the subgrid ribbon (ignore other two - Main grid & Form), right click the OOB button & hide it (this is also a backup)
4. Add a new button & custom javascript action command (follow this)
5. Open your custom HTML webresource using openWebResource method in javascript function
