it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)
View 1 RepliesI have a PDF document with a number of text fields, several of which have a maximum length - namely, a maximum number of allowable characters. Is there a way using iTextSharp to determine this setting? Here's the code I have so far:
Dim reader As New iTextSharp.text.pdf.PdfReader("Foobar.pdf")
Dim inputFields As IDictionary(Of String, iTextSharp.text.pdf.AcroFields.Item) = reader.AcroFields.Fields
For Each key As String In inputFields.Keys
Dim PDFFieldName As String = key
Dim MaxFieldLength As Integer = ???
...

View 1 RepliesI've had an "interesting" request .
1) Is it possible, in a multiline textbox, to automatically break to the next line after 100 characters?
2) If not, is it possible to parse the enter key as entered by the user to break the line in the code behind?
Some additional info:
The person requesting this does not think that the user should use a single line textbox limited to 100 characters and click an "Add Line" button to store that field in a table.
The person requesting this is of the belief that a DEC Alpha-based system that currently does this can be replicated on the web.
how to limit the number of characters per line in a multiline textbox? Any posibility to do this with javascript? I have the users enter a list of names and need to limit each. I hate to use another textbox to add each name. If so, I would then add them to a listbox instead so they could select and remove a name.

View 1 RepliesI couldnt help but notice that if you have a FileUpload-control, and then try to upload a file thats bigger(in bytes) then the allowed maxiumsize, then the site crashes or some wierd "Connection problem"-page shows up, atleast for me in Firefox...
So my question is simply...is this just for me?..and if not, how do I fix this the best way?...cause the current "crash-page" aint a nice way of handeling the problem in my opinion...whould be much better to actually just show some custom-page that lets the user know that thier trying to upload a file thats way to big..
i want to validate my password textbox that it should be minimum length of 7 charsthe code i m using is this
Code:
if (textbox1.text.legth>7)

label1.text="invalid";
}
now the problem is this is it everytime check when the page is postback i.e when ever page is return from server.
A very easy one hopefully - what expression can I use to validate an integer to ensure it is greater or equal to zero, but less than 2,147,483,647 (i.e. the maximum value of an integer)?
For example 0 =< x < 2,147,483,648
