Hello,
I have added new navigation link at Opportunity entity. In this, I am displaying a webresource which is a pure .net page. So same as like what we have "Products" option in Opportunity entity, I need to have one more option next to "Products". When user select that option, instead of displaying Opportunity Products associated view, I need to display .net page hosted on CRM server itself.
This works fine. Now what I need to do is, if someone navigate to any other page from this new navigation menu, I need to display alert from that .net page. So how I can achieve this?
