View 4 RepliesI 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 have a ListView (in an update panel) bound to an ObjectDataSource (connected to an NHibernate object) and in the EditItemTemplate I use Text='<%# Bind("HideLocation")%>' to bind to a string property of the object.
When I click edit (twice, another issue I'm having) and view the code in Chrome, the output looks like this:
[code]....
why the value of the bound data (in this case: In locker 2317) is showing up outside of the text box instead of as the contents of the data?
I want to let TextBox control TextChanged event fire only when there are more than one character in the TextBox.

I'm sure this will need to use javascript but not sure exactly how to do it. I need to count the characters typed in a textbox and when it reaches 10 I want a sub to be called in the code. Or have it click a button on the screen which is probably easier. How to do this? I would think I would call the script with the OnTextChanged? And in the script use the .length property to see if it is 10? Maybe I just answered my question here!!
