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".
I am trying to add a validation of the textbox.text.length in a FormView and prevent the insertion of being made in case the text length is not compliant (less than four characters).
In the scenario when clicking the submit button an Alert should appear with xxxx warinig text. and the Insert command being prevented.
This is my FormView Insert Template:

I have a few applications/websites running with LINQ to SQL and the other day I decided to go ahead and optimize some of the queries, etc and I found that the size for variable length data types is derived from the parameter value instead of the column actual size? for example a column is defined as nvarchar(30). when I use linq to query that column with a value that's 5 characters long the parameter in sp_executesql will be defined as nvarchar(5)...this causes a major procedure cache bloat even for a small utility site that has a lot of queries is there a way to optimize this?

i am trying to read file from a stream.
and i am using stream.read method to read the bytes. So the code goes like below

Now the above gives me error because the last parameter "outputMessage.FileByteStream.Length" returns a long type value but the method expects an integer type.
