Showing a value on a grid that doesn't belong to the associated store

[nuno_Santos]

Hi everyone,


i have a problem using a grid. Maybe is a bit odd, but here it goes.

    public class Person
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public int IDCountry {get; set;}
    }

    public class Country
    {
        public int IDCountry { get; set; }
        public string CountryName { get; set; }
      
    }

Let's assume i have this 2 classes. On my aspx, i have a store that receives a datasource, List<Person>.
In the grid that uses that store, how can i show the countryName instead of the countryID that is associated with that person?

In trying to use <Renderer> to call an Ajax function that receives the ID and return either de countryName or the whole Country obj. Like in the example, i can make a Ext.Ms appear afer de responser from the server, but i can write the country name on the column.

Any ideas?

Thanks,
Nuno Santos

Hi Vladimir,

fast reply. :)

I miss that example completely.

I try to reproduce that making the changes for my case, but i get an error in javascript, saying that the StoreCombo is not defined ( on the Fn function).



Can you help me?

Thanks,

You need define own *store which contains Countries*

Hi,


I did and the error occurs when the javascript try to get the country by id.

Hi,


I solved this problem.

Instead of having a function, i wrote all the code in the handler itself, taking advantage of the #{} syntax.

So, may handler look like this:

<Renderer Handler="var r = #{StoreCountry}.getById(value); return Ext.isEmpty(r) ? '': r.data.CountryName;" />

If someone have the same problem, this solution is working for me.

Nevertheless thanks very much Vladimir for putting me on the right track.
