APEX

Sure,

What is the problem with zoom out ?

Hamza,
Problem with a zoom out occurred with items but it was just a workaround. I'd like to have the IG with feature like I pasted above on the screenshot

IG Cookbook app have an example like that on my workspace :
Workspace: hamzasoft
Username/Password: demo/demo0000
Application 138659 - Page 5

It's not a solution, I need to dynamically sum a column inside the IG, not as an item in another region.

This is not a built-in feature, it needs more JS, in this case it will work if your IG pagination is scroll with aggregate. I have an example on my workspace :
Workspace: hamzasoft
Username/Password: demo/demo0000
Application 62472 - Page 17

Hamza, thanks a lot! This is exactly what I needed

For newer APEX releases take a look at
JSDoc: Interface: model (0 Bytes)properties aggregates.
For example EMP table SAL column add to JS init code:

function(options) {
    options.defaultGridColumnOptions = {
        aggregates: ["SUM"]
    };
    return options;
}

This is much less code than the old way!

@john-snyders-oracle thanks a lot! It's working great but I struggle with one thing, how to round values?

I think all you need to do is give the column a format mask. I tried FML999G999G999G999G990D00. This is the declarative option Format Mask for a number column.
One other note for using aggregates option is that the IG must have a primary key defined.

@john-snyders-oracle I tried with FML999G999G999G999G990D00 and it's still the same, I have a number column type and a primary key in my IG.

Just give the column a format mask.

@hamza-alabbasi
Do you have a JS function to get a sum of multiple columns in IG

Hi md-sameer,
Please open a new thread and explain your issue.

hi ,
I have added the same logic in SUM column properties but I couldn't get the total value

function(options) {
    options.defaultGridColumnOptions = {
        aggregates: ["SUM"]
    };
    return options;
}

Hi John Snyders-Oracle, can this value assign to any page item?
Thanks.

@robin-biju When using model field option aggregates the aggregate value cannot be stored directly in an item. There are ways to data out of a model into an item but it can be trickier for aggregate rows. (Model method getAggregateRecord is not documented and not clear how useful it is.)
If you want to save the aggregate value to a page item you can use the method shown in the IG Cookbook page 5.
