c# - Update issue with data-bound Listbox and PropertyGrid -


this part of aoi class (nothing special it):

class aoi : inotifypropertychanged {     private guid _id;     private string _name;     private string _comment;      public guid id     {         { return _id; }     }      public string name     {         { return _name; }         set         {             _name = value;             onpropertychanged("name");         }     }      public string comment     {         { return _comment; }         set         {             _comment = value;             onpropertychanged("comment");         }     }      public override string tostring()     {         if (_name.length > 0)         {             return _name;         }         else         {             return _id.tostring();         }     }  }

i keep them in bindinglist<aoi> bound listbox. in selectedvaluechanged event of listbox assign selected object propertygrid, user can modify aoi.

this works fine except name field (which displayed in listbox (see tostring() above)).

when edit name field using propertygrid, listbox updated correctly. in propertygrid, name field (just value) cleared press enter. correct (modified) value appears when set cursor field in propertygrid.

what easiest workaround handle correctly?

this problem of propertygrid.

this can reproduced designer within visual studio. select control , change minimum size larger value current one. if take grid, value in size property won't updated till select within grid.

if rows won't update correctly 1 of these 2 options help:

  • reattach object propertygrid calling propertygrid.selectedobject = myobject
  • force grid redraw calling propertygrid.invalidate()
