SMTP Server

To fix this, we will have to make sure that no other mailservers are running. Then we have to startup SMTP service (via services). After which, Inside Manager Server, "Manage Mail Server", "add a POP3 acccount". Use that as the default SMTP details.

Form does not get value from readonly fields

To fix this, don't put readonly property for the controls by default, do it programatically. This has something to the storage of values for disabled properties. Apparently .NET does not store the value of disabled controls and hence does not pass the value on.

txtStartDate.Attributes.Add("readonly", "readonly");
txtExpDate.Attributes.Add("readonly", "readonly");
