Addition operation on quick edit mode

[gkarakas]

Hi,

We need to make an addition operation on related items in quick edit mode. When the user enters a value or changes the value of two columns, the sum of them should be calculated on the third column automatically. How can we do that?

Dear gkarkas,
As I've mentioned in another topic recently, it's not possible with JS, at least as far as I'm aware. You can use Calculated column for this, or try a Workflow (but this won't be visible without refreshing Related Items). You can google solutions for Quick Edit mode SharePoint List, it's identical to Related Items.
