Solution 1

Use System.DBNull whenever you have that case and then it will save NULL in your database.

Solution 2

Check using

if(String.IsNullOrEmpty(YourTextbox.Text))
{
     //Now set data as DBNull.Value
}

It will save Null in database.

Also if you dont specify the value in insert statement it will automatically set itself as null by default.
