There are two methods in which you can solve your problem.
1. Combine all (Radiabutton ,DropDownBox) value into one and pass that value to SQL query.
string dropDownBoxValue1 = string.Empty;
string dropDownBoxValue2 = string.Empty;
string radioButton1Value = string.Empty;
string combineAllValue = string.Empty;
bool isChecked = radioButton1.Checked;
if(isChecked )
radioButton1Value=radioButton1.Text;
.......
.......
dropDownBoxValue1 = Convert.ToString(DropDownBox1.SelectedValue);
dropDownBoxValue2 = Convert.ToString(DropDownBox2.SelectedValue);
combineAllValue=radioButton1Value +","+dropDownBoxValue1+","+dropDownBoxValue2
Note :- combineAllValue pass this value to query String.
2. Combine all values in Stored Procedure and then store to table.
