c# - What is the alternative for DisplayMemberPath="Value" for Windows Store applications? -


i think there bug windows store applications when comes using displaymemberpath="value".

here code

    <combobox height="40" verticalalignment="stretch" selectedvaluepath="key" displaymemberpath="value" x:name="combobox1" fontsize="25"/>  var source = new dictionary<string, double>();             source.add("item1", 0.4);             source.add("item2", 0.3);             source.add("item3", 0.1);             source.add("item4", 0.1);              var formatedsource = new dictionary<string, string>();              foreach (var item in source)             {                 formatedsource.add(string.format("[{0}, {1}]", item.key, item.value), item.key);             }              combobox1.itemssource = source;

if use code in wpf in works perfectly. if use code in windows store application combo box empty , error thrown. there alternative way in windows store applications , have unearthed bug? because have researched web days , found no solution this.*please not comment unless have tried code windows store app not wpf in visual studios.

i've been able reproduce in universal app (windows phone version).

to solve it, first remove "height" property value on combobox, because prevent combobox show options when open (on windows phone @ least).

then, in code behind, try converting dictionnary list (or dictionnary) of objects (i used anonymous objects, better create custom type) :

combobox1.itemssource = formatedsource.select(f => new { key = f.key, value = f.value }).tolist();

so xaml looks : 

<combobox x:name="combobox1"               verticalalignment="stretch"               displaymemberpath="value"               fontsize="25"               selectedvaluepath="key" />

right now, don't understand what's going on raw dictionnary, @ least should have workaround now.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
