Hi @NELSON_D1 :

It depends of many factors. To fill the whole child at once, maybe method 1.
frm.add_child lets you adds data row by row.

From backend can use

Hope this helps.

image1172×203 61.1 KB

Here, i want to filter this values, then set them to another tables
like there is total of orange color is 8, so i want to set another table like orange total is 8,

how do I do this, i create the button below this table, click the button, it filter the table then set
best practice for setting values from the backend or frontend??

Hi @NELSON_D1:

Again … it depends.

I would prefeer do it calling to backend method … if you don’t need to show this sumarized/filtered data on front side.
