c# - EXT.NET Combobox in gridpanel show value instead of text -

-

i have big problem in ext.net. have gridpanel combobox inside. combobox work fine when grid load, if click on combobox edit, combobox show me value instead of text. if select 1 of possible item in combobox, save result , retry edit same combobox, @ time value show correct (i see text , thi correct.) follow code:

the render function:

var statusrenderer = function (value, st) {         var ind = st.find("value", value);         var r = st.getat(ind);         if (ext.isempty(r)) {             return "";         }         return r.data.text;     };

the column in gridpanel:

<ext:column id="columnprofilo" runat="server" dataindex="profilo" text="profilo">                             <renderer handler="return statusrenderer(value, #{storeprofilo});" />                             <editor>                                       <ext:combobox id="comboboxprofilo" selectonfocus="true" emptytext="select class"  triggeraction="all" querymode="local" runat="server" displayfield="text" valuefield="value">                                     <store>                                         <ext:store id="storeprofilo" runat="server" autoload="true" >                                             <model>                                                 <ext:model id="modelprofilo" runat="server" idproperty="value">                                                     <fields>                                                         <ext:modelfield name="text" />                                                         <ext:modelfield name="value" />                                                     </fields>                                                 </ext:model>                                             </model>                                                     </ext:store>                                     </store>                                     <listeners>                                         <beforequery handler="delete queryevent.combo.lastquery;" />                                     </listeners>                                 </ext:combobox>                             </editor>                         </ext:column>

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
