dependent dropdowns in gris=d editor

[Santosh Dhumale]

I have a EditorGridPanel which contains two columns, country and state, each being implemented as a combobox. User can add as many rows as he/she wants. I have a list of countries and cities in in the corresponding stores and everything is working fine now. I want to add one enhancement to it for which i need some help. Currently i am loading all the cities in the combobox, instead of that, i want to load only the cities from selected country. I cant think of a way to do this, appreciate your help

HI!

i guess, you may filter your city combo depending on the value of country combo.

just use select event on your country combo and filter the city store.

Sample for filtering:-

Yes I did like it. when I changing the country the state combo store get changed and I am able to store this values in database.but what after the when I reolad the grid.

After displaying grid the associted state combo must have only those values with respect to country combo value of that row.
