How to get the value of a cell?

[george.wei]

Hi! All,

If a column is not bound to a field of grid's data source, can I retrieve the value of a cell belongs to this column?

For example:


var colModel=new Ext.grid.ColumnModel([
{header:"Selected",width:40,
editor: new Ed(new fm.Checkbox())},
{id:"id",header:"ID",width:20,sortable:true,locked:true,dataIndex:"id"},
{header:"Name",width:100,sortable:true,dataIndex:"product.name"}
]);

grid=new Ext.grid.EditorGrid("grid-example", {
ds:ds, //ds is an instance of Ext.data.Store
cm:colModel,
selModel: new Ext.grid.RowSelectionModel({singleSelect:true})}
);


How to know which records are selected? Thanks for any clues.

Regards,
George

Ooh...
Thanks for your reply. But actually, I mean how do I know which records are tagged as selected/checked according to my example? The first column uses Checkbox editor, but it doesn't bind to any field of grid's underlying data store.

That is how you know which records are selected. But you want to use checkboxes for selection?

A Grid cell is always bound to a Record Field. How else is the value from that cell going to be stored? It is stored in that row's Record.

That will be using field 0 from the record as its underlying data. You will have to add a boolean Field to your Record to hold the value.

Although this is not for an Editor grid, I needed something similar so this might help you: http://extjs.com/forum/showthread.php?p=20549#post20549. As Animal says it needs to be bound to a field, in my example, this is basically a "calculated" field not in the underlying data.

OK, thans you two. I'll try to add an extra field.
