Is there any way to show "Add item" member on icon data view?

[kohhy]

Hello,

I'm making a map viewer based on this example, and I want to show 'Add map' icon in the top of data view.

This is sample image:
addmap_image.png

But, there are two problems:

1:
I try to do this by code below:

    initComponent: function() {
        this.store = Ext.create('Ext.data.Store', {
            autoLoad: true,
            fields: ['mapName', 'mapID', 'meta'],
            proxy: {
                type: 'ajax',
                url : '/maplist.json',
                reader: {
                    type: 'json',
                    root: ''
                }
            }
        });
        
        this.callParent(arguments);
        this.store.sort();
        this.store.insert(0,{mapName:'Add Map ',mapID:'__AddNewMap__'});
    }

But, not add item for add map icon, it is overwrite by ajax data.
How can I add extra item in top of data items?

2:
If I add "add map" item not as extra item but as the item included in data, it works.
But another problem is, if I make a sort, "add map" item is also sorted.

Is there any way to avoid sorting for some items?


Thanks,

Can you insert a new item on the store load listener?

Scott, thanks!

I could add it.

And, is there any way to make it item always being top if they items sorted?

Since it is on the load event, it will insert(0,..) after sort reloads the record.
