Question

Is this possible to send a DB null to a integer variable.

I’m calling a function

private void BindGridView(String Fromdate, String Todate, int IsPending)

1. fromdate
2. todate
3. ispending is my stored procedure scalar variable

On pageload I show the both detail (ispending or not pending). For this I need to pass null.

Is there need to change the signature of function?

Answer 1

Make the int parameter nullable, then check for a value when calling your sproc:

private void BindGridView(String Fromdate, String Todate, int? IsPending) {

and then

cmd.Parameters.AddWithValue("@intParam", 
                 IsPending.HasValue ? (object)IsPending.Value : DBNull.Value);
