[CLOSED]combo box does not display anything if number of records are greater than 134

[hellosudhir]

I'm using combo box in grid editor. and i have to populate a long list ( around 250) in a combo box.
but when the number of records exceeds 134 then combo box does not show anything when i click it.
is there anything i can do to show the records? am i missing anything??
any help would be appreciated.

thanks

Hi hellosudhir,

I have honestly never heard of this issue before. I'll check it out myself. In the meantime, I'd like to move your post to the Ext 3.0 Bugs forum so it can be properly tracked and ticketed if necessary.

Thanks,
Jarred

EDIT: I went ahead and tested a ComboBox with 1000 items. It was operating just fine. http://dl.dropbox.com/u/12081268/Combo1000Items.png Perhaps you can send your code over and allow us to take a look. Screenshots? I will still move this to the Bugs forum to proper review. Thanks.

Ext.onReady(function(){
    var data = [];
    for(var i = 0; i < 500; ++i){
        data.push({
            id: i,
            name: 'val - ' + i
        });
    }
    
    var store = new Ext.data.JsonStore({
        fields: ['id', 'name'],
        data: data
    });
    
    new Ext.form.ComboBox({
        store: store,
        triggerAction: 'all',
        displayField: 'name',
        valueField: 'id',
        mode: 'local',
        renderTo: document.body
    });
});

Works fine for me. @hellosudhir Please post a test case.

Hi
thanx for reply.

below is the section of my code:

xtype: 'gridcolumn',
header: 'Manufacturer',
sortable: true,
width: 100,
dataIndex: 'T7F6',
id: 'Manufacturer',
editor: {
xtype: 'combo',
store: 'ManufacturerStore',
lazyRender: true,
mode: 'local',
displayField: 'T3F3',
valueField: 'T3F3',
editable: false,
triggerAction: 'all',
ref: '../ManufacturerRef',
id: 'UpdateManufacturer'
}
don't be confused with value in dataIndex, valueField and displayField, i used combination of table no. and field no. to represent a field and made jason data to return like that.

below is the json data for 140 records returned by ManufacturerStore:

{"success":true,"tM":141,"rs":[{"T3F3":"Merck Generiques"},{"T3F3":"GFL"},{"T3F3":"Sunways India"},{"T3F3":"Sanderson"},{"T3F3":"Cipla, India"},{"T3F3":"PurePharma, India"},{"T3F3":"P2"},{"T3F3":"Portex"},{"T3F3":"NICHE"},{"T3F3":"HSL"},{"T3F3":"Australia"},{"T3F3":"BDH,industries"},{"T3F3":"Square Pharmaceuticals"},{"T3F3":"Surgisup"},{"T3F3":"SAPL"},{"T3F3":"Astra"},{"T3F3":"Plasmatec"},{"T3F3":"3M"},{"T3F3":"Livingstone International PTY Ltd"},{"T3F3":"Golden cross"},{"T3F3":"Sigma"},{"T3F3":"Pfizer"},{"T3F3":"Claris"},{"T3F3":"Alphapharm"},{"T3F3":"Sanofi"},{"T3F3":"Pacific, New Zealand"},{"T3F3":"Orion"},{"T3F3":"PFK, Australia"},{"T3F3":"Sandoz"},{"T3F3":"Gracure, India"},{"T3F3":"Mallinckrodt"},{"T3F3":"Unilab, India"},{"T3F3":"Pharmatel"},{"T3F3":"Rotexmedica"},{"T3F3":"Bayer"},{"T3F3":"Ciron"},{"T3F3":"Aventis"},{"T3F3":"Hartmann"},{"T3F3":"Glaxosmithkline"},{"T3F3":"Smith & Nephew"},{"T3F3":"CSL Biotherapies"},{"T3F3":"Terumo"},{"T3F3":"Hamilton, Aus"},{"T3F3":"Mayne, NZ"},{"T3F3":"Douglas, New Zealand"},{"T3F3":"Novartis"},{"T3F3":"Roche"},{"T3F3":"Helathcare Logistics"},{"T3F3":"Apotex, NZ"},{"T3F3":"Ashford"},{"T3F3":"PSM, NZ"},{"T3F3":"Mid West"},{"T3F3":"Phebra, Aus"},{"T3F3":"Sinochem"},{"T3F3":"Xepa Soul, Malaysia"},{"T3F3":"IDAMAN Pharm"},{"T3F3":"Dyna pharm"},{"T3F3":"Whatman USA"},{"T3F3":"Holden Netherlands"},{"T3F3":"Hovid, Malaysia"},{"T3F3":"edico"},{"T3F3":"Hospira"},{"T3F3":"Medi Crepe"},{"T3F3":"Semina"},{"T3F3":"CSPC"},{"T3F3":"SM Pharma"},{"T3F3":"Vernald"},{"T3F3":"LabServ"},{"T3F3":"Multichem NZ"},{"T3F3":"Elastoplast"},{"T3F3":"China"},{"T3F3":"BD"},{"T3F3":"Littman"},{"T3F3":"Valeant Phamaceuticals Australia"},{"T3F3":"Star Wood"},{"T3F3":"Pfizer"},{"T3F3":"Energizer"},{"T3F3":"Baldwin"},{"T3F3":"EPOCH PHARM"},{"T3F3":"KARKA PAK"},{"T3F3":"Ansell Gammex"},{"T3F3":"Advantage II"},{"T3F3":"UPHA pharmaceutical"},{"T3F3":"sunward pharmaceutical"},{"T3F3":"Atlantic lab,Thailand"},{"T3F3":"alcon"},{"T3F3":"Beximco, Bangladesh"},{"T3F3":"Bode"},{"T3F3":"Ecipse"},{"T3F3":"Soonmelt"},{"T3F3":"B.Braun"},{"T3F3":"aspen pharm"},{"T3F3":"holden,netherland"},{"T3F3":"laboratory,santiago"},{"T3F3":"Pharmacy Health"},{"T3F3":"Anspec Pty Ltd"},{"T3F3":"ainmedicare"},{"T3F3":"Galentic, India"},{"T3F3":"Remedica"},{"T3F3":"Micro labs, India"},{"T3F3":"Medreich"},{"T3F3":"Medopharm, India"},{"T3F3":"Adcock Ingram"},{"T3F3":"Martindale"},{"T3F3":"Fronine Lab Supplies"},{"T3F3":"baxter"},{"T3F3":"SMS"},{"T3F3":"SMA"},{"T3F3":"SENTRY"},{"T3F3":"Ranbaxy, India"},{"T3F3":"Arrow, NZ"},{"T3F3":"Flamingo, India"},{"T3F3":"RHR India"},{"T3F3":"novo nordisk"},{"T3F3":"fabrique,canada"},{"T3F3":"Ego, Aust"},{"T3F3":"Serum institute india"},{"T3F3":"Reckitt Benkiser, Australia"},{"T3F3":"Mentholatum Pharm-Australia"},{"T3F3":"Suru International Pvt.Ltd"},{"T3F3":"Aurobindo Pharma-India"},{"T3F3":"H-Bio Juven Pty Ltd-Australia"},{"T3F3":"Chauvin Pharmaceuticals-England"},{"T3F3":"Allen & Hansbury-UK"},{"T3F3":"Unimed- Switzerland"},{"T3F3":"Tevapharma- Holland"},{"T3F3":"DBL Mayne Pharma- Australia"},{"T3F3":"ZLB-Behring-Germany"},{"T3F3":"Biotech Pharm Pty Ltd-Australia"},{"T3F3":"Holland"},{"T3F3":"Gland Pharma, In"},{"T3F3":"Multigate"},{"T3F3":"Suture India Pvt.Ltd"},{"T3F3":"AFT, New Zealand"},{"T3F3":"Spinal needle 20G 3.5""},{"T3F3":"Spinal Needle 22G x 3.5""},{"T3F3":"Unisis"},{"T3F3":"Mucus Extractor 10Fg"},{"T3F3":"Indoplast"},{"T3F3":"Askina"},{"T3F3":"See comment"}]}

That doesn't really add much extra information, please follow the guidelines: http://www.sencha.com/forum/showthre...-the-Bug-Forum

[hellosudhir]

Hi,
sorry about the guidelines.
i think i found what was causing the problem.
it was the format of my json data: there were two extra double quote in my json data
when i removed those quote, combo box showed all records... :-)

sorry for that.
thanks.
