Hi!

I'm playing with new grid and I have a question. In 0.33 ColumnModel has a 'sortType' parameter, so one can do some changes to column data for sorting.

But in 1.0 sortType didn't work. I read forum topics, looked at examples, but failed to understand how to do "advanced" sorts in new Ext.

The sort types in the new grid are much easier to use and most of the time aren't needed.

For example, when you define a field as type "int", any incoming data (i.e. XML String) are automatically converted to int, data is automatically sorted as an int, etc.

The same applies for type: 'string', 'date', 'float'. For strings, they are automatically sorted case insensitive (unlike old version).

However, if you require a custom sort type there are options for that as well. You can reference one of the predefined sort types by name (see SortTypes.js):

sortType: 'asText'

and you can also pass in a function (including a custom function):

sortType: Ext.data.SortTypes.asText

The type and sortType options are on a field in the record definition.

Thanks for the answer, Jack! Adding sortType to the record definition works fine.

I really need to use custom sort function in my app, cause data I have to display is quite complex.

Referencing sorting function by name doesn't help in my case (ext 1.0). A column with integer values is still sorted as text.

{id: "s_6", header: "State" ,width: 64,dataIndex: 's_6' ,type: 'int', sortType:'asInt'}

The function ds.fields.get('s_8').sortType -- comes back as function (s) { return s; }

Is there a trick to make this work?
