I have a FormView that allows a user to register for a company event. I want to do a couple of things with this form.
1. I need to write this data to a MS SQL database
2. I need to send an email confirmation of their registration to their email.
I know how to do both of these things, but i am having trouble doing both at the same time.
It would be nice if I could do it in one click, but I coded it into two pages to try to help simplify it.
The first page allows the user to input their information into a formview and when they click the submit button, it places those answers into session variables:
[Code]....
[Code]....
The Second page confirms the users information by taking those session variables and placing them into labels:
[Code]....
[Code]....
However, after I place information into the formview on the first page, it throws up this error:
"Conversion from type 'TextBox' to type 'String' is not valid".

Above is my code. The error I'm get is, Unable to cast object of type 'System.DateTime' to type 'System.String'.
The column "To" and column "Subject" are strings and column "Receive" is DateTime. I can't made any changes in the database, so I need to write some code to handle casting a string to datetime or if statement as a work around.

I seem to be having issues with posting forms with DropDownLists. I've looked all over the net and tried various solutions, but none seem to work for me.
I'm getting the following error: The parameter conversion from type 'System.String' to type 'Models.Organization' failed because no type converter can convert between these types.
Here's my ViewModel:
[Code]....
Here's my controller:
[Code]....
The objects are generated by ADO.NET Entity Framework. Organizations is its own object, but also a property of Profile (each user belongs to one organization). Now I understand what the error message is saying, just not sure how else I'm supposed to do this.

I have defined an ODBC Command and ODBCdatareader as follows
OdbcConnection myConnection = new OdbcConnection(connectionString);
OdbcCommand myCommand = new OdbcCommand();
myCommand.Connection = myConnection;
myCommand.CommandText = "select UOPGM from GREG.TUSROPTF";
OdbcDataReader myReader;
myConnection.Open();
myReader = myCommand.ExecuteReader();
When I try to retreive from the reader as follows:
while (myReader.Read())
{
string someString = myReader["UOPGM"];
lstNames.Items.Add(someString);
}
I get the following error
Error reading the database. Unable to cast object of type 'System.Byte[]' to type 'System.String'."
I have also tried string someString = (string)myReader["UOPGM"]; to no avail
