Hi everybody,

as all of you guys, I need a dropdown2 (subcategories) populated when another dropdown1 (categories) is changed.

I have an inline grid.

If I use the approaches explained in this forum (dataUrl and Ajax calls) everything works fine but what I want now is to

avoid all those Ajax requests to increase my site performance.

My idea is to load every option in the first load of the page so I have created a JQuery function (populateFromLocalValues)

to change the dropdown2 values working with them locally.

When I change a value in dropdown1 the values are correctly populated in dropdown2 throughtthe implementation of a

change function in the “change dataEvent” of the dropdown1.

My problem comes when I have to initialize the values of dropdown2 when I select a row. I'm using the following code:

{name:'subcategory_id',index:'subcategory_id', width:110, align:”right”, sortable:false, editable: true, edittype:”select”,
