Databinder.Eval and Substring -

-

im using repeater control , databinder display data database website. example: databinder.eval(container, "dataitem.title")

sometimes text long use substring display preferred string in length. how do databinder , if text long (> 20 characters) want truncate , leave 3 dots behind. how ?

i'd suggest extension method heavy lifting, in order make markup simple possible:

public static string evaltrimmed(this repeateritem container, string expression, int maxlength) {      string value = databinder.eval(container, expression) string;     if ( value != null )         return null;     if (value.length > maxlength)        value = value.substring(0,maxlength) + "...";     return value; }

then use in markup as:

<%# container.evaltrimmed("dataitem.title", 20) %>

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
