To enable edit mode on Interactive Grid immediately when page loads (to save users a double click), you can create a dynamic action to run custom JavaScript on page load:

• Set Static ID on your Interactive Grid region – lets call it MYIG1
• Create a Dynamic Action on event Page Load and on True event let it execute the following JavaScript Code

apex.region("MYIG1").call("getActions").set("edit", true);

Up to this part all is well and if you page is not very log, problem solved. But if the page is longer you will notice a side-effect – the page gets automatically scrolled to set focus on the Interactive Grid. To fix it append a scroll up code to the JavaScript snippet above, so a full example would look like this.

apex.region("MYIG1").call("getActions").set("edit", true);
$("html, body").delay(500);
$("html, body").animate({ scrollTop: 0 },0);

That little bit of delay is necessary, otherwise scrolling will not work. It will also introduce a little bit of “page flickering”, but at least the page focus is back on top when page is loaded.

Tested with APEX 24.2.
