asp.net mvc - How do I retrieve the VALUE of the object's property that is passed to my custom EditorFor from the view? -

-

system.web.mvc has htmlhelper contains method called editorfor renders editing control associated data type in view.

im trying create own editorfor method extending asp.net mvc 2 htmlhelper. have following:

    public static string editorfornew<tmodel, tproperty>(this htmlhelper<tmodel> helper, expression<func<tmodel, tproperty>> item)     {         string value = "";         string name = item.tostring(); // corrected in comment answer below!         type type = typeof(tproperty);          if (type == typeof(int) || type == typeof(int?) || type == typeof(double) || type == typeof(double?) || type == typeof(decimal) || type == typeof(decimal?) || type == typeof(float) || type == typeof(float?))         {             return helper.textbox(name, value, new { @class = "number" }).tostring();         }         else         {             return helper.textbox(name, value).tostring();         }     }

can explain how retrieve value of object's property passed view?

you need use modelmetadata:

modelmetadata metadata = modelmetadata.fromlambdaexpression(item, helper.viewdata);

you can value metadata.model property.

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...
