how can bind number after d in stringformat?

you can't bind stringformat part of binding expression. can instead add together property view model "valuedisplay".

public string valuedisplay { { homecoming string.format("{0:" + valueformat + "}", valuevalue); } } public string valueformat { { homecoming _valueformat; } set { _valueformat = value; raisepropertychanged("valuedisplay"); } } private string _valueformat;
