View 2 RepliesForms Data Controls :: Conversion From Type 'TextBox' To Type 'String' Is Not Valid?
Sep 6, 2010I 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".

Validators - RangeValidator Can't Do Even The Most Basic Math?
Jun 3, 2010I'm having an issue with my ASP.NET RangeValidator controls.
I want to allow users to enter a discount amount, and this amount must be negative (< $0.00). I want to verify that the amount entered in a textbox is a negative value, so I have this in my page markup:
<asp:TextBox ID="tbxDiscount" runat="server" />
<asp:RangeValidator ID="rvDiscount" runat="server" ControlToValidate="tbxDiscount"
MinimumValue="0.0" MaximumValue="0.0" EnableClientScript="true"
ErrorMessage="Please enter a negative value for a discount" />
and I attempt to set the MinimumValue dynamically in my code before the page gets rendered - to the negative equivalent of my item price. So if the item is $69, I want to set the minimum value to - $69:
rvDiscount.MinimumValue = (-1.0m * Price).ToString();
Trouble is: I keep getting this error message:
The maximum value 0.0 cannot be less
than the minimum value -69.00 for
rvDiscount
WTF?!?!??! Where I come from, -69 $ IS less than $0 ...... so what's the problem?

VS 2008 - How To Call Sub When 10 Characters Type In Textbox
Sep 21, 2011I'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!!
