        }     } 

the problem code doesnot work. once fill relevant data on page, , click submit button not save database. help.

problem : if region cookie null not inserting default value.

solution : need add default value if region cookie becomes null. need add else block store default value asbelow

try this:

if (request.cookies["region"] != null) {     textbox5.text = server.htmlencode(request.cookies["region"].value);//read cookie } else{     textbox5.text = string.empty; } 

edit:

try this:

if (radiobuttonlist2.selectedvalue.tostring().trim().equals("pending"))
