c# - Controller returning file header to view not file -

-

my form looks 

{  using (ajax.beginform("log",                         new ajaxoptions {                              updatetargetid = "lessontable"                         }))    //removed dropdown list ect... readability   input type="submit" name = "submitbutton" value = "filter"            input type="submit" name = "submitbutton" value = "print report"

and controller this

[httppost]     public actionresult log(lesson lesson,string submitbutton)     {         /*retreive lessons*/         list<lesson> lessonlist = (from l in storedb.lessons                                    l.statusid != deleted                                     select l).tolist();          /*filter retreived lesson*/         lessonlist = filterlesson(lesson,lessonlist);          switch (submitbutton)         {              case "filter":                 return partialview(lessonlist);              default:                 {                     return detailsreport();                 }         }       }

the detailsreport() method returns file

 return file(renderedbytes, mimetype);

when click print report button updating div file header not requesting user opens file. have tried removing updatetarget id doesn't prompt file download. when make ajax.actionlink call details report method working fine.

thanks

if understand doing, working intended; because making request ajax.beginform(), trying display ever returned in page. removing target not expected change that.

you should make "print report" button part of separate form or not form @ all, , have pull info needs existing form before submitting (since wouldn't automatically once removed form)

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
