    Dependent fields needs to be part of the core Ext Platform really. They could easily build in your technique.

    I mean there is a much easier way for this
    But I donno how to use that.From API it seems each will do the required.
    I would like to get a sample implementation



    each( Function fn, [Object scope] ) : void Calls the specified function for each of the Records in the cache.
    Calls the specified function for each of the Records in the cache. Parameters:
    • fn : Function The function to call. The Record is passed as the first parameter. Returning false aborts and exits the iteration.
    • scope : Object (optional) The scope (this reference) in which the function is executed. Defaults to the current Record in the iteration.
    Returns:

    Store
    My store is store = new Ext.ux.data.PagingJsonStore({
    fields : fields,
    url:'loadxxxxxx.do',
    root: 'result'

    });
    I am retriving all the records from the store
    var records = [].concat(store.allData.items);
    Now i would like to iterate over the records for a validation.
    But my colums in the grid are dynamic .
    I would like to know by any means ,could we retrive the column defenition from the store or record .
    gor eg: if i gave any index is it possible to get the colum name in that location.

    A store doesn't know anything about columns, only about records and fields.

    Do you mean fields instead of columns? A store has a 'fields' property that holds a MixedCollection.

    ps. store.allData is also a MixedCollection, so it also has an each() method.
