I have a contact page with fields like E-mail Address, Name, Subject, and Message. I use a RequiredFieldValidator on each text box. They work fine when I test it with the Visual Studio built-in development server, but on IIS7, they don't work and they allow the Send button's click event to be fired.
View 6 RepliesI have 2 date fields - From and To Date.Both are using required field validators, regular expression validtors and compare validators. When the user enters an invalid date range, e.g. 02-29-2010 to 02-29-2010 (non-leap year), the comparevalidator throws an 'from cannot be greater than to date range' error.Why am I seeing this error when From is not > To.Here's the code snippet

I have required field validators in my ASP.NET application form.
In the button click event of the FORM, i.e. OnClientClick(), I am calling a javascript function to validate the controls in this same page. Due to this the required field validators are not getting fired.
I need both the javascript function be fired on the button click , as well as required field validators also to work efficiently.
I have created a form with several textboxes and a dropdown list and assigned a required field validator to each of them. I also have a master page with several links to other pages, some made using <a href=..> and some linkbuttons. The problem I am having is that when I click the linkbutton links they do not redirect to the proper page, rather they trigger the validators for all textbox fields and display the validator characters next to each textbox (and the dropdown). When I fill out the form, those links redirect properly. The links created using <a href=..> do not cause this problem.

I created some required field validators and a validation summary control. When I get an error it displays next to the control its validating and also inside the validation summary control. I only want the error to display in one place; inside the validation summary control. I tried making the required field validator invisible but then it didn't display anywhere.How can I get the errors to only display in the validation summary control? There is no need to display them twice it just clutters up the page.
View 3 RepliesI have an html input control that is a radio button. This radio button needs to disable required field validators when selected. This is my non working code so far. What have I not done?
<input ID="card1" runat="server" type="radio"/>Card<br />
btnSubmit_Click
{
if (card1.Checked == true)
{
RequiredFieldValidator10.Enabled= false;
}
}
this however doesnt disable the control.
How can I use required field validators in the insert item template in a listview control? The empty fields in the insert item template are preventing the user from deleting or updating ay other row.

View 1 RepliesWe are using regular expression and required field validators. They work fine, especially in out of the box environments like the log in control.
When used on other controls, e.g. a textbox, they also work, but we note that the whole site is in effect shut down until the expression is valid. I.e. the user cannot click cancel, or a link. The site only starts working again after the expression has been made valid.
How can this be fixed?
The validators should only apply to the control to validate and to the control that would cause the value of that control to be posted back to the server (e.g. a button), not the whole site.
I have defined a field validator that works fine on normal behavior on a page:
<asp:RequiredFieldValidator runat="server" ErrorMessage="errroooorr" ControlToValidate="TextBoxHouseNumber" Display="Dynamic"></asp:RequiredFieldValidator>
Now if I dont insert any text in the TextBoxHouseNumber field, and push submit, the FieldValidator fires as it should. But if I now click a button that automatically fills the TextBoxHouseNumber with text from a Jquery/Ajax function, the field validator still shows. It´s like "Hey, the user hasnt made any changes to the textbox, so I wont bother check it".
I will do my best to explain what I am trying to do. This is a form that will allow the user to change his/her password with RequiredValidators in place.Here's how to reproduce the problem that I can't seem to figure out.1. Please open up the aspx file into a browser.2. Click the "Save" button. The required validators should kick in and prompt a "Required" message.3. Key in any word in the "Change Password" textbox except for the word "pass" since I have hardcoded it into the aspx file just for example sake over here.
4. Key in anything for both the "New Password" and "Confirm New Password" textbox.5. Click the "Save" button again. You should be able to see "Your current password is incorrect." next to the "Current Password" textbox which is a Literal control.Here's the problem: How do I hide or get rid of the Literal control when I click save again? Right after the form does a post back, all the password textboxes are empty and I can't find a way to bypass the required validator controls and then screen would look like this below.I will attach my changePass.aspx file code below for reference.
I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".
I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?

I have an ASP.NET form for currency exchange requests. There are two text fields there: amount-source and amount-target.
One of them must be filled and only one.
How to implement this using Validators, if applicable?

Imagine the scenario of a contact form, whereby data is to be collected and further transmitted via email to the appropriate address. One of the important fields asks for an email address, pretty vital to instrumenting the call-back. So say I check for the entry of something, anything, in the mail address field using a RequiredFieldValidator; a further check in code will determine if the mail address supplied is usable, or not. Given that both of these checks are essentially validation, I would simply like to reuse the RequiredFieldValidator from my code-behind; is this possible? For example, something as simple as:
MyValidator.Show();
return;
What I have done in the past is add a Label to the form as well, and just use a similar tactic, only making the control visible as needs be and returning. Ideally I'd like to get rid of this altogether and simply use one control to output my error message. For an idea of current code, below is a skeletal listing, which, even as such, is the concept in its entirety: Within the page:
<asp:TextBox runat="server" ID="MailAddressTextBox" />
<asp:RequiredFieldValidator runat="server" ID="MailAddressValidator" ErrorMessage="Enter a valid mail address" ControlToValidate="MailAddressTextBox" />
<asp:Label runat="server" ID="MailAddressError" Text="Enter a valid mail address" Visible="false" />
And within the code-behind:
MailAddress enquirerMail;
try
{
enquirerMail = new MailAddress(MailAddressTextBox.Text);
}
catch
{
MailAddressError.Visible = true;
return;
}
The pitfall with the approach of hiding/showing error labels, other than the obvious of extra controls, is the maintenance of their visibility, and also a label for each error, or lists of messages and in-code alterations to the display.
Also, multiple validators is something I want to avoid, at least in this particular instance; a RegularExpressionValidator won't cut it here, as we all know just selecting the 'best' regex for parsing mail addresses can be a feat in itself, or maybe it will contain more characters than the actual page content + markup. Another reason for my aversion to regex, should you need one, is that, ultimately, I have to implement the above try/catch validation regardless, as even a 'validated' address may cause failure in the MailAddress constructor.
Page validation using Required field validator is not firing I configured everything and tested in other page and found its working fine.
I placed my controls under TabContainer is that the reason for not firing.
I'm trying to write a form for a user to leave a testimonial on the website. I would like a group of inputs related to the users name (title, firstname and surname) or an input for their company name to be required. They can leave both if they like, but they must at least either fill in all the inputs related to their name or the input for their company name.can I do this with the RequiredFieldValidator?

I have a form that contains times and dates. Each of these controls has a required field validator so that the user must put in the date and time. This apprears to work fine in testing. The data is stored in sql tables which are then worked with in the office using an Access Database. The webforms are simply used for gathering the data. In analyzing the data, they are finding that there are instances when no time has been stored. I don't know how the insert information could be saved if the control was blank. To make matters worse, the staff swear that they are entering the times.
Sometimes while registering on the website people don't provide correct details like name and e-mailIn order to check correct e-mail it is better to use e-mail activation link send to their e-mail.But how to make sure the user is providing correct name ?I am really impressed by the Facebook name recognition system, it we try to use any word which is not a name, it asks you to enter a valid name.Is there any way we can make use of asp.net requiredfieldvalidator to check if user is providing a correct name or not ?I know we can make use of requiredfieldvalidator to see how many alphabets / special symbols etc butIf we put minimum alphabet requirement - in that case user can enter "....." and can easily bypass the requiredfieldvalidator or a user can easily write "iamfakeuser" instead of name and bypass the requiredfieldvalidator.
question is how to check if name is correct or not just like facebook registration form ?
I'm trying to use a field validator to make sure one of my list boxes has a selection before the user is able to proceed to the next page. i'm having is that if the validation message is triggered, all of the buttons on my page loose functionality.Meaning, if I purposely trigger the validation control, I can't get rid of the error message and none of my buttons do anything when clicke after this.

Is there something that I need to add to the code behind of the page or the Java Script that I'm using?
