I need the updated value of Opslag Marge when adding value on the Opslag edit box and click on the Update Items and Qty's button

I have checked sales.js productConfigureSubmit : function(listType, area, fieldsPrepare, itemsFilter) and also check Mage_Adminhtml_Sales_Order_CreateController but not understand how can update custom price on order create in admin.

Answer 1

I have to get a solution from sales.js which is located at js/mage/adminhtml/sales.js. in that file, I have to find productConfigureSubmit that is saved and put data when pressing the Update Items and Qty's button.

productConfigureSubmit : function(listType, area, fieldsPrepare, itemsFilter) {
    area = this.prepareArea(area);
    this.loadingAreas = area;
    var url = this.loadBaseUrl + 'block/' + area + '?isAjax=true';

    // prepare additional fields
    fieldsPrepare = this.prepareParams(fieldsPrepare);
    fieldsPrepare.reset_shipping = 1;
    fieldsPrepare.json = 1;

    // create fields
    var fields = [];
   for (var name in fieldsPrepare) {
       fields.push(new Element('input', {type: 'hidden', name: name, value: fieldsPrepare[name]}));
   }
   productConfigure.addFields(fields);

   // filter items
   if (itemsFilter) {
       productConfigure.addItemsFilter(listType, itemsFilter);
   }

   // prepare and do submit
   productConfigure.addListType(listType, {urlSubmit: url});
   productConfigure.setOnLoadIFrameCallback(listType, function(response){
       this.loadAreaResponseHandler(response);
   }.bind(this));
   productConfigure.submit(listType);
   // clean
   this.productConfigureAddFields = {};
   },
