For example if I choose 22k option in Combo Box the current price related to the gold should be retrieved from internet or any url related to commodity pricing.
Method name->modified for combobox.
Can anyone help me to Figure out exact solution.
It depends what data source you want to use. The usual approach is calling a web service providing the data, although you may also get a file to import, extract data from an HTML table or who know what.
Thank you
I will see to it.
