First of all, thanks for the new TextEditor extension. It was essential for my projects.
Is there a way to activate a text-color toolbar button too? Or maybe it will be on next release?

Yes, it could be very useful for me too. Any help would be appreciated

Easyui 1.4.5 version is the answer. On form, set "iframe" property to false and use "OnProgress" event to update progressbar plugin.

Yes, the 'iframe' property will be available, which can be set to submit the form via 'iframe' or 'xhr2'.

Finally tested new 1.4.5 version. It's perfect. On forms now I can use the iframe poperty and bind "OnProgress" event on progressbar plugin update. Thanks.

Perfetct. I just sow on documentation the new properties and events of form and filebox plugins. It's what I was looking for.
....Waiting for new 1.4.5 version. Great job.

I'd like to extend form features to have "upload file progress"  like this very interesting implementation: http://malsup.github.io/jquery.form.js
For now, someone can help me?
It could be a request for next version of easyui?

I need to show a progress bar (with real values) when uploading file on server with a form. How can I do that? I found several examples on the web with jQuery uploadProgress option of ajaxSubmit(); it's possible to extend form easyui plugin with this option? 

Ok, maybe i found a solution.

Code:

$('#fb').filebox({
   buttonText: 'Select...',
   onChange: function (newValue, oldValue) {
   // This to show all files list on the textbox (otherwise it shows only last selected file with the "fakepath" issue)
            var f = $('#fb').next().find('.textbox-value');
            var listfiles = '';
            $.each(f[0].files, function(index, item) {
                if (listfiles.length > 0) { listfiles = listfiles + ', '+ '"'+item.name+'"'; }
                else { listfiles = '"'+item.name+'"'; }
            });
            $(this).textbox('setText',listfiles);
   }
});

// This to set the right property "multiple" on the input file tag
$('#fb').next().find('.textbox-value').prop('multiple',true);

I'm using easyui-filebox plugin, but i can't select multiple files. How can I enable this feature?

It's simply  a personal consideration. It could be a good practice on extensions site pages to show a changelog, a version number or at least a "last modified date". It's very difficult for me realize if I'm using the latest version of any extension.

Perfect jarry, it is what i'm looking for

The 'onBeforeLoad' event fires before loading the remote data. Returning false will abort the request to the server.

Thanks jarry, your code could be a good start point but on my datagrid I'm using pagination option; when I change page with invalid filter field nothing happens (so your code works fine) but page indicator changed always. How to avoid this?
Another good solution could be to avoid the load data event if the filter is not valid.
For example, is there a way to use "onClickMenu" event introduced by filter-row extension, to avoid adding a filter rule not validated by validatebox?

I'm using datagrid filter row extension with remoteFilter option enabled and it works fine.
Now I'd like to avoid that filter action starts when typed text lenght is less then 3 char. This is my code to enable this filter:

Code:

dg.datagrid('enableFilter', [{
   field:'description',
   type:'validatebox',
   options: {validType:'minLength[3]'},
   op:['contains','equal','notequal','beginwith','endwith']
}]);

The validatebox object works fine (I see the expected alert message for too short string), but it's always possible to apply the filter.
Any idea?

That's ok. I think for best visual result it should be

Code:

var h = $('#dg').datagrid('getPanel').find('div.datagrid-header div.datagrid-header-check');
h.removeClass('datagrid-header-check');
h.addClass('datagrid-cell');
h.html('<span>Final</span>')
