string str = "Select * From Vendor Where(VendorID= '"+ DropDownList1.SelectedValue +"')";
check whether VendorID is int or string, if VendorID is int then use "DropDownList1.SelectedValue" if VendorID is string then use '"DropDownList1.SelectedValue"'

it will render in back end as, select * from table where id is '2'-- this is wrong because ''is for string...... so we have to mention as, select * from table where id is 2 and for name field, select name from table where name = 'xyz'-- this is correct

One small suggestion..The when you build a query string try to execute that in the DB first. With quotes query would have given you the error in DB itself.
