EnhancedGrid Indirect Selection Sorting

[denov]

you can see the bug in the demo for indirect selection on ​http://docs.dojocampus.org/dojox/grid/EnhancedGrid

if you select a couple rows and then sort the grid the records all get sorted but selected rows do now change to reflect the sort. So if you sort by movie title, select the first row, and then reverse the sort you'll see the wrong row is now selected.

looks like these are ones that evan is working on

It's a known issue for single sorting in DataGrid?.

This is fixed when nested sorting turned on in EnhancedGrid?, please see the first demo on ​http://docs.dojocampus.org/dojox/grid/EnhancedGrid EnhancedGrid? inherits the single sorting when nested sorting is off - I think that's the reason why you saw this issue.

In the latest nightly build, this feature is disabled by default and only applicable in EnhancedGrid? with client data store, you can turn it on with <div dojoType="dojox.grid.EnhancedGrid?" keepSortSelection="true" .../>

With this patch selection will be persisted across various use actions, e.g. sorting, filtering or pagination etc. Applicable both for client/server side stores.
But there is a key precondition - Identifier(id) is required for store, as id is used for differentiating row items.
Known issue - The preserved selections might be inaccurate if some unloaded rows are selected by range(e.g.SHIFT + click)
To turn on this - set 'keepSelection' attribute to true, e.g.
<div dojoType="dojox.grid.EnhancedGrid" keepSelection = true .../>

(In [23422]) With this patch, selection will be persisted across various user actions, e.g. sorting, filtering or pagination etc.

• Applicable both for client/server stores.

Key precondition

• Store Identifier(id) is required since id is used for differentiating row items.

Known issue

• The preserved selections might be inaccurate if some unloaded rows are selected by range(e.g.SHIFT + click)

Usage

• To turn on this, please set 'keepSelection' attribute to true, e.g. <div dojoType="dojox.grid.EnhancedGrid?" keepSelection = true .../>

Fixes #10855 !strict

[evan]

(In [23667]) Refs #10855, fix missed scenario - select/deseelct all vs. unloaded rows are selected/deselected by range(e.g.SHIFT + click), !strict

[evan]

(In [25497]) Refs #10855 shouldn't keep _connects[] in class scope

[evan]

(In [25579]) Fixes #7304 !strict by leveraging selection persistence across DataGrid?, TreeGrid/LazyTreeGrid?. Refs #10855

The selection persistence feature is still limited with

1. Key precondition - Store Identifier(id) is required since id is used for differentiating row items.

2. Known issue - might not be accurate if some unloaded rows are selected by range(e.g.SHIFT + click)

Usage - To turn on this, please set 'keepSelection' attribute to true, e.g. <div dojoType="dojox.grid.DataGrid?" keepSelection = true .../> or

<div dojoType="dojox.grid.TreeGrid?" keepSelection = true .../> or <div dojoType="dojox.grid.LazyTreeGrid?" keepSelection = true .../>
