OK, I created an Ext 3.2 compatible PagingStore.

New features in v0.5:
- Only for Ext 3.2 (and up?).
- Added PagingGroupingStore (although I don't recommend using it).
- Added Ext.ux.PagingStore with doRefresh patch and support for adding/removing/clearing records.

Hi Condor

I know you don't recommend using your great plugin with a GroupingGrid. However, is it possible in case if let say group C spans across 2 pages, recalculate a page size after load and apply paging again with a new page size to avoid the spanning?

Thank you

[Condor]

Yes, you could do that.

For initial load I recommend using suspendEvents/resumeEvents to stop it from displaying the page with the wrong pageSize.

Hi Condor,

Thanks for your great work on this UX. It works and performs great even with large record sets (5000+)!

Yesterday I moved a project to Ext 3.2.1 and also upgraded the PagingStore to the new 0.5 version. I then noticed a behaviour which caused a problem for me:

In version 0.5 the START and LIMIT params are also being send to the server when retrieving records, version 0.41 did not have this behaviour.

Is this intentional and what is in your opinion the best way to prevent this without have to do 'server side' adjustments?

I suppose replacing:

this.proxy.request(Ext.data.Api.actions[action], rs, options.params, this.reader, this.createCallback(action, rs, batch), this, options); 

with:

this.proxy.request(Ext.data.Api.actions[action], rs, this.baseParams, this.reader, this.createCallback(action, rs, batch), this, options); 

Does fix this for me. However this is not really a 'correct' fix.

What are your thoughts on this?

Many thanks for this UX and your help is very much appreciated!

Thanks Condor

But if I suspendEvents on beforeload or on load, how I can check if group C spans across 2 pages? I will not be able to use for example store.collect('groupfield') to get unique fieldname and compare the set per page. Is there any better solution how can I check if group C spans accross 2 pages, and if yes, get a number of records grouped by group C and recalculate a paze size by adding this number to the initial page size and reload the store?

A simple example will be really usefull.

Thank you in advance

how to place a date field on toolbar..please help with code..i want that date to be inserted into the grid

[Condor]

Completely untested:

store.suspendEvents();
store.load({
  callback: function(){
    var limit = ... // calculate limit for first page based on first group
    store.resumeEvents();
    store.load({params: {start: 0, limit: limit}});
  }
});

Is this related to PagingStore? If not, please start a new thread.

Hi!

I'm using PagingGroupingStore in a grid and everything is fine with that, but the sort options of the grid don't work :\
Is it normal this conflict?
