Web Forms :: Set Text Box Max Number Of Characters?
Aug 10, 2010
How can I set a asp.net text box to accept up to 20 characters? I was trying the range validator and I set it up to 0 min value and 20 max value. The prolem is that if I write 12933, the range validator errors appear saying "only 20 characters allowed" so I think it is adding the values.
I have a column in my repeater which allows as many as 255 characters and causes the page contents pushed away to the right if any of the record has all 255 characters in that column. How can I tell it to wrap the text after 50 characters?
I 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 = ??? ... Next
I need to set MaxFieldLength to the number of allowable characters for the current form field being iterated over.
On my current form I have it validating a Canadian Postal Address (xxx xxx). The space is optional but if the user does not use a space, then once the validation passes it will insert one. How can I count the first 3 characters of the textbox, insert a space, then add the rest of the characters?
I have a form that's used to submit emails. I'm not sure what the character limit should be for the body of the email. I'm thinking about setting it at 150. It's used to allow people to inquire about services provided by a small business. Should I allow more? Is this sufficient?
On my products page I have a small thumbnail and a description that is pulled from the database, since there is space restraints, how do I allow a max amount of characters, and if the description is longer append ... to the end? I'm using a data repeater and data binding for the content inside it.
I use this query for my table but it retrives the value for each row. It does not retrieve the size of the column name. I need to know the number of characters occupied in particular column. How do i get this value?
I am trying to figure out how to get the text value from each textbox on a page that has a dynamically created number of text boxes. I need to store that value in a database row. I guess what i need is to be able to store the text box values in a collection or arrary of some sort and then be able to use textbox(i).value or something of that nature. Not really sure where to begin.
I have a textbox on my page and I only want the user to be able to type into it up to 4000 characters. Currently if they type in more than 4000 characters it will take it, but when I save it to the DB it either cuts off after 4000 or does not save it at all.
I'm using the ASP Validation control a wanted to test that multiline textbox content was between 2 and 40 characters. Any character can be provided, including the new line character. What would be the expression? What I have below fails.
I am using mySQL. I have separate tables for several languages. When I display the Greek statements I seem to be limited to between 192 and 201 characters. That is not the problem with English, Danish, Dutch, Russian, or Farsi. I am using the same code for each with the only change being which table is opened. (In fact I just took the Dutch code and changed only the name of the table I'm opening to the Greek table and had the same problem.)The problem is that I've also double checked the statements in the table and they are complete, e.g., some have up to 255 characters.
I have been looking for the best way to obtain the total number images in a folder where the first two characters on the file name are XX and place this number into a variable.So for example - I have a folder containing the following images:
XX-01.jpg XX-02.jpg XX-03.jpg YY-01.jpg ZZ-01.jpg
So I would populate the variable with 3 in this case.Does anyone know of any way to do this?
