I want to prompt the user to enter up to four specific months as an input on my page. Should I use a textbox control and just apply validators to it? or a check list box? which would control what the user puts it and would make it easier to iterate through the selected items? The only concerns I have are the looks of the list box. Can I make it look and feel like a drop down box? Also, how do I limit the selection to 4? If I use a text box, how do I validate that "up to" 4 items are entered let's say separated by a comma?

I'm trying to update a db record via a business object, based on a users input.
In my button event handler, I check for a null or empty value like this before I set the object properties:

But if the textbox is empty, I get the "System.FormatException:
Input string was not in a correct format." in the line:

How can this be?

I have a custom user control with some input fields and a submit button. I need to validate the fields using the jquery validation plugin when the submit button is clicked. (The function of the submit button is to create another custom control which displays the data entered in the above mentioned control)
Bt as far as I knw, validation plugin works only with form validation ryt? And my custom control does not contain a form tag as I am using master pages. The custom control is present in one of the content pages and the master page already contains a form tag with a runat=server attribute. And I guess one page can contain only a single form tag with runat=server attrib ryt?
So how do I get it to work?

I developed a screen in which there are fields like first name,username,password and email. I validated these fields using javascript and came to know that javascript is not that safe. So i decided to validate on server side also. My question is whether i can use asp controls like requiredfieldvalidator, regularexpression validator to validate the form or i have to validate through server side coding??

Before committing the record from the postback of the Create or Edit method in my controller, I validate the values in the form against some business rules in the GetRuleViloations() of this domain object. The following rule example is written in two ways. The 1st one validates against the numeric values in form, the 2nd one validates using the associated object (lookup table in database) description via the foreign key. I would like to use the 2nd method, but during the Create postback the associated object is always null.

I need to validate that a user makes a selection from a select list OR they enter text into a textbox. I'm trying to figure out which validator to use. Is there a way to make a CompareValidator do this? Or would I need to write a custom validator? If custom, do I write one for each of the form elements, or does the validation happen upon submit?

(Using ASP.Net 2.0 on Visual Studio 2005, coding in C#)I write in the hope that someone will be able to provide a clue as to how I might best overcome this issue:I've got a form with 2 RequiredFieldValidators, and 2 buttons. Button 1 has 'CausesValidation' set to 'False', and populates some of the other fields on the form from the database (via a postback).Button 2 fires the validation, then if the form is valid brings a javascript popup confirmation box and then, if true, it puts the data in the form into an email.All this is working fine. However......My problem is this: If I press button 2 with my required field(s) empty, the form quite correctly refuses to submit, and highlights the appropriate field(s) with a red *.But: if I then press button 1 (my populating button) it DOES NOT FIRE until I press it a second time!Code snippet follows (markup only - I will of course post code-behind if nec. but I don't think it is)
<script type="text/javascript">
function ConfirmSubmit()

In order to use hidden input, does the hidden input must be inside a form?
Is there any strategy to perpetuate the hidden input value between requests? So far I guess it's through query string / URL?

I have a form and stored procedure that inserts the data from the form. It works fine except that if a field isn't filled in it doesn't insert a NULL into sql it inserts "".
I've tried a few different ways but none seem to insert NULL, the one below still inserts "", can anyone point me in the right direction.
Here is the required part of the code, if you require more just let me know.
[code]....
So if I enter nothing into address1 field it should write NULL to screen but it always writes NOT NULL.

After deploying a ASP.NET WebForms application to a production server some of the ajax calls has stopped working for me. After some debugging I found out that the following statement (in the internal client-method WebForm_DoCallback) was causing the problem:
xmlRequest.open("POST", action, true);
The problem seemed to be that the action-variable was empty so after checking the rendered html I found out that the form-tag rendered on the production server looks like:
<form method="post" action="" id="Form1">
However, on my developer machine I get the following:
<form method="post" action="default.aspx" id="Form1">
So, why would the action-attibute render on my dev.machine but not on the production server? This seems to be the case only for one specific web form, when I look on other pages the action-attribute renders correctly.

I am really new to AJAX and Web Application development in general. What I am trying to do is relatively simple, problem is...I'm just not sure how to do it.
I wish to popup some sort of control that contains a "asp:Label" and an "asp:TextBox" where I can input a value into the textbox. Is this possible to do with AJAX? If so, how is it done?

I have a form that when submitted shows a busy animation and disables the submit button.
Anyone know how to query Microsoft's Sys.Mvc.FormValidation to see if the form passed it's test so I can prevent the busy animation showing if the form hasn't actually been submitted? Or even some other work-around? In case it's relevant - I'm using Data Annotations for my validation.
At present my client side javascript looks like this:

I have an ambitious requirement for an asp.net 2.0 web page that contains a table (gridview), and each row in the grid contains 6 select (dropdown) controls for data entry. The number of rows that will be displayed is dependent upon the user's search parameters, which are specified in another area of the page. Unfortunately, with the default (and even basic) search parameters specified, the grid could contain several hundred rows. I've noticed that the browser, in this case IE8, starts behaving rather erratically once I reach a large number of rows -- no documented evidence for the number of rows where this begins to be a problem. For example, trying to view the source of the page results in a message from IE stating that there was a problem with the page that forced the browser to reload it, and I never get the source. Obviously the page loads and renders rather slowly also.
I know that my solution is probably going to involve paging the gridview such that it only displays 20 or so rows per page, and I'll have to write code to handle the saving of changes in the dropdown values when the user changes pages. I can probably turn off viewstate on the gridview also. However, the question I really want to pose is this -- has anyone seen a documented rule indicating the maximum number of input controls that an HTML browser form is supposed to be able to contain? I could not find anything on the Internet after doing a search, and I suspect the answer may be whatever the browser can handle based on the machine configuration it is running on. Any rules of thumb you use?

I have an ASP.NET application designed for a Windows CE device that needs to take in information from a scanned barcode. The device sends the scanned data as string input with a crlf to whatever field has focus. I set up my page with a textbox that takes the input and posts back to look up the item.
Now, I'd like that box to not be visible to the user, but IE complains when I set focus to it if the field is "visibility: hidden" or "display: none". I've tried moving it off screen using absolute coordinates, but setting the focus scrolls the window to the new location.

I'm using Josh Bush's MaskedInput plugin for jQuery in an ASP.NET 3.5 Webform app. How to get rid from the literals in the code-behind file after form submit? E.g: a phone input with the mask $("#txtPhone").mask("(99)9999-9999");
In the code-behind:
string customerPhone = txtPhone.Text
Which returns me: (12)3456-7890
But this is what I want: 1234567890
In the plugins changelog page it says I can use mask() method with no arguments to archieve this. But how to do it from the code-behind?!
EDIT
I want to send to the server the unmasked value. How to do that?
