Maybe you could post the C++ code that shows this problem?

i havnt use any code for binding with grid,it directly bind through object datasource and the function for edit is.......

public void EditStatus(stri ng statusname,stri ng statusdesc,int pk_autstatusid)
{
db.ConnectionSt ring = Conn;
db.Open();
db.CreateParame ters(3);
db.AddParameter s(0, "statusname ", statusname);
db.AddParameter s(1, "statusdesc ", statusdesc);
db.AddParameter s(2, "pk_autstatusid ", pk_autstatusid) ;
int a = db.ExecuteNonQu ery(CommandType .StoredProcedur e, "EditStatus ");
}

over here wen i pass null value in statusdesc at that time the error comes....

db.AddParameter s(1, "statusdesc ", statusdesc);
db.AddParameter s(2, "pk_autstatusid ", pk_autstatusid) ;

It looks like there are two AddParameters functions:

AddParameters(i nt, string, string);
AddParameters(i nt, string, int);

Which one are you talking about?

Also, what do you mean by null value in statusdec? statusdesc is a string object and string objects do not have null values.
