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'm now facing a problem with the listview, on my web form, I have a listview with a textbox at the end of each row, a Submit button, I bind my listview datasource to a table in my database via LINQ, (name Daily Money), here I want that when I click on Submit button, I want to retrieve the text that user typed in the textbox of each row, I tried many ways but it just give me an empty string (the value that was bind to the text on pageload) (first I didn't bind anything to the textbox, second I bind it to a column of the table but all failed).
I used item.FindControl, but it didn't work, how can I retrieve the textbox's value that user typed in (using foreach), or a way to update the listview datasource, I want to insert, update those textbox's value to my database,

I am using jquery autocomplete. Its working fine. Only issues I have is with its display.Now I have a textbox where users type in the text. Below the texbox are some other controls such as texbox, dropdownlist etc.Now when the user start typing in my autocomplte textbox it shows all the suggestions below but it still displays my controls below, i mean my result should be over the controls below and my results box should overlap my controls. Right now it seems my results box is transparent.Here is the css that I currently have.

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!!

I have a textbox and an updatepanel. As I type, I want to be able to update the updatepanel. Right now, all I have is when the textbox loses focus, it updates. What is the .NET 4.0 method for doing this? Clarification: this is not autocomplete on a textbox.

i have a textbox, dropdownlist and a listbox. these 3 controls form my search engine where i can type some characters on the textbox then select one option from dropdownlist(eg.department), the listbox will populate names from the department that contain the characters. However i have one problem, my database contain all data in uppercase so when i type lowercase letter in the textbox nothing will be populated. Only when i type uppercase characters then something will populate. I think it got to do with my sql statement but i do not know how to do it

I am not sure if I have found the right forum for this one.
the problem is:
I have a .licx file in my rootfolder.
I am getting the error:
Error 53 Unable to resolve type ' <add type="TabStrip" version="7.0" />' C:inetpubwwwrootCrop_ApplicationCrop_Applicationeo_web.licx 7 Crop_Application
,which I get for all the types that are in the xml file(i just gave one of them).
A friend told me that I have to add the type .licx in the MIME type in the IIS .
The problem is that I find the MIME type, I add the extension type .licx but I do not know the MIME type for .licx

I think this is a little tricky problem, but I need to solve it somehow. I have a texbox in my asp.net page. I want to show all names when a user types in a letter in that textbox, whatever names starting with that letter. the names are from a list generated by other function, pulled out from active directory. So for example: User types in "a" in a textbox then automactically names "aron" "asron" "amanda" in the list shows, and user can select one of those names.

I'm trying to create a validation layer that will contain methods to validate all my objects (in my Business Objects layer) .. but when I try to reference both the validation and business objects to each other I get a circular dependency error .. so I've decided to create a new layer (BLL) to validate the objects for me and I'll be able to reference both the validation and the object layers.
so I want to build some kind of class/interface -I don't know what fits more- to be like a generic type or a parent type that my method could accept it as a parameter and check for it's Name/ID property. Instead of defining a new method overload for each object type I have

I have built a dataset named Transaction_Time.I called it on Page_Load
Transaction_Time tranTme = new Transaction_Time();
put it in the session.
Session["Transaction"] = tranTme;
Then I call that session and cast to dataset.
DataSet dstTranTime = (DataSet)Session["Transaction"];
I got the following error.Unable to cast object of type 'Transaction_Time' to type 'System.Data.DataSet'.
