c# - Epicor10-Image.Save method -

i trying build customized window in epicor 10. have added picturebox , try open picture(bmp) file , button save somewhere else. problem in customization tools dialog epicor 10, write code when compile keep getting error:

error: cs1061 - line 258 (953) - 'object' not contain definition 'save' , no extension method 'save' accepting first argument of type 'object' found (are missing using directive or assembly reference?)  ** compile failed. ** 

now, when have copied code, , re-created windows form app visual studio 2012, works fine, no errors on compilation @ all.

the code quite simple:

private void epibuttonc6_click(object sender, system.eventargs args) {     var fd = new savefiledialog();         fd.filter = "bmp(*.bmp)|*.bmp;| jpg(*jpg)|*.jpg;| png(*png)|*.png";         fd.addextension = true;          if (fd.showdialog() == system.windows.forms.dialogresult.ok)         {             switch (path.getextension(fd.filename).toupper())             {                 case ".bmp":                                             epipictureboxc1.image.save(fd.filename, system.drawing.imaging.imageformat.bmp);                     break;                 case ".jpg":                     epipictureboxc1.image.save(fd.filename, system.drawing.imaging.imageformat.jpeg);                     break;                 case ".png":                     epipictureboxc1.image.save(fd.filename, system.drawing.imaging.imageformat.png);                     break;                 default:                     break;             }         }        } 

epipicturebox not derived system.windows.forms.picturebox. derived infragistics.win.ultrawineditors.ultrapicturebox.

the image property on system.windows.forms.picturebox of type system.drawing.image image property of infragistics.win.ultrawineditors.ultrapicturebox system.object. why things not behaving expect them to.

i able mockup working using following work long sure whatever assigned proptery of epipictureboxc1.image indeed going able cast system.drawing.image

switch (path.getextension(fd.filename).toupper())         {             case ".bmp":                                         ((system.drawing.image)epipictureboxc1.image).save(fd.filename, system.drawing.imaging.imageformat.bmp);                 break;             case ".jpg":                 ((system.drawing.image)epipictureboxc1.image).save(fd.filename, system.drawing.imaging.imageformat.jpeg);                 break;             case ".png":                 ((system.drawing.image)epipictureboxc1.image).save(fd.filename, system.drawing.imaging.imageformat.png);                 break;             default:                 break;         }
