In my application, if I do not input the value into the textfield, it will show error message: "The value '' is invalid."
However, is it possible to check one more thing: the length of the textfield? For example, it will show the error message if I input more than 10 chars? And is it possible to change the message "The value '' is invalid." to "Missing Value"?
I need to let my users enter a variable length list of items into something that looks like a grid view (or a series of standard text boxes stacked vertically). Each item could be a few characters or a few hundred characters long, and I just want them to enter a "sentence", and then tab to the next row, and always having another blank one ready to go at the bottom of the list.
I don't want to save any data to my SQL Server DB until they enter the entire list and then click on a "save all" button. When they hit the "save all" button they will be given a preview screen where the data will be presented as standard HTML ordered list. If they confirm/save, then each row of the grid will then be saved as a separate row into my SQL Server database (with an index to remember the order).What ASP.Net (or Jquery/javascript) UI control would be the best to use in this situation? (i.e. just for the data entry part - the rest I got covered).
I've added some validation to a text box which works, only the code behind on the image button executes even if the validation shows a problem. I need some way of testing the validation and blocking the code behind from running. He's my code:

I have a two-character field for US State. I add a RegularExpressionValidator control to validate the input using
ValidationExpression="[a-zA-Z]{2}"which works to validate the content when something's entered, but it doesn't catch if someone just leaves the textbox blank.
Is there any way to validate within the same regex to catch an empty textbox?

Below is the condition i want:
total_display_all = "2,10,4,25,17" 'length = 5
Dim I_total()
As
String = total_display_all.Split(",")
Dim alphabet = string
Dim alphabet_all = string
For i = 0
To I_total.Length - 1
alphabet_all = alphabet 'don't know how to write this part of codingNext
final output i want:
when length = 5, alphabet = "A,B,C,D,E"
when length = 2, alphabet ="A,B"
when length = 10, alphabet = "A,B,C,D,E,F,G,H,I,J"
the alphabet depends on the length of total_display_all.
i don't know how to write the coding to loop through alphabet.
I'm looking for ways to reduce the size of my page . I have a page that just renders a gridview - no images - and it is over 400k!
Looking at the html that is generated I see the names of the controls in the gridview are very very long. For example: ctl00_ContentPlaceHolder1_releaseGV_ctl149_lblBuy
My gridview is about 200 rows by 13 columns = ~ 2600 spans with very long names rendered. The above example is 49 characters X 2600 controls = 127,400 characters just in control ID's!
The actual data on my page ins't anywhere near a tenth of that!
I am already storing viewstate on the server.
YES, I will put a pager on this page to bring down the number of rows. Also, I've seen sever other posts related to page size with some excellent content. I will follow up on them - however I have not seen this specific question answered.
Here is a sample of my page. As you can see there is not much data and a lot of html!

The last thing I have is an Add and Save button and what I would like to achieve is add/update the record based on if it exists or not. To do this I would like to check the state of the tutorial object to see if it has been loaded and use its id without needing to put it on the page for reference later.
Will the tutorial object still contain values after postback and how can I check if its been declared?
