CheckMarx scan on dot net application -


checkmarx scan complains "element’s value flows through code without being sanitized or validated , displayed user in method onitemdatabound " in places drop down values passed or selected.example:

strtext = dropdownlist.selectedvalue;

return dropdownlist.selectedvalue;

how sanitize these values?can htmlencode , decode apt avoid such vulnerability results?
