Answer 1

try using Request.Form["radion_button_name"]

eg

string strPlace='';

if (Request.Form["rbMode"] != null)
 {
     strPlace = Request.Form["rbMode"].ToString();
 }
//=strPlace will return Null if No radio button is selected.

and use your code base on the value on selected radio button .

if(strPlace=='1')
{
//save image in location 1
}
else if(strPlace=='2')
{
//save image in location 2
}
else
{
//error you have to select the location type using radio button.
}
