ValidationSummary Is Not Displaying With RegularExpressionValidator
Sep 17, 2010
below is the code and when i select a wrong filetype i get instant red "*" but i dont see the validation summary and there is a buton("upload") and when i click on it than i get the validation summary error message.
my question is: why validation summary is not displaying when i select the wrong file type?
With client validation enabled, is there a way to force the ValidationSummary created by
<%= Html.ValidationSummary()%> to show up the same time the other validation messages appear? And obviously be updated as more error messages need to be displayed.
I am new to using the MVC so experiencing a few beginners issues with understanding how the validation works. I have a form with 3 fields, when the user submits the form I need to ensure at least one box has data in it. So I have created a custome ValidationAttribute for my model, here is what the model code looks like:-
I am posting back to the server to check the DB to see if we hold a reference number. If the reference number does not exist I set two custom validators to invalid and change the ValidationSummary header text. The problem is that the background colour I set in the css class does not display. The font colour does display correctly.
When the validation summary is displayed using client side script the styles are displayed correctly. i am not sure why they dont when there is a post back.
I am new to ASP.NET so may be my question sounds stupid but here is it anyway: Why a postback happens when we use aValidationSummary control? When I am using RequiredFieldValidator control then postback is not happening if the validation fails which is right. But if I useValidationSummary control then postback starts happening even if the validation should fail.
I have 2 text boxes txtUserName and txtPassword and a button btnLogin on my page. I have a RequiredFieldValidator control for each text box. If any of the text box is empty and I click the Login button, the postback does not happen and I got error message(s) which is good.
[Code]....
Now I add a ValidationSummary control. Now if any of the text box is empty and I click the Ok button, the postback happens which is bad.
I have to customize a validation scheme for my form because required validation is only necessary if 2 other conditions are met; I have this figured out, but is there a way to add the messages to the ValidationSummary Control using C#
I have a Gridview control on my webpage which is loaded using a GridViewTemplate dynamically. I have added FormatValidators toemailaddress, date type data fields. I also have a ValidationSummary control to show the error summary at the bottom of the page.Now, on the webpage, when a user enters incorrect data into two emailaddress fields, the ValidationSummary control summarizes the error messages and shows same error message twiceone per row. I think this is a standard behavior of the ValidationSummary control.
My question is, is there anyway to show the error message only once per column i.e. even if two email address fields are incorrect, the error message shown by validationsummary will appear only once instead of twice? I am referring to showing the validationsummary once per column of gridview instead of once per row...
I have ValidationSummary in masterpage out of UpdatePanel and inside updatePanel i have my ContentPanel. I have an user control where iam having Save button which iam using in all my pages of application. Now i have a requirement like i need to show the validation summary in ModalPopUpExtender.
how do i go about modifying the display of the validationSummary control in asp.net i want to modify it completely not just modify the color of the text etc.has anyone got any sample code etc ?
I'm trying to add a new html attribute to my ValidationSummary Html control like this:
<%= Html.ValidationSummary(new { id = "validationSummary" })%>
VS compiler has no problem with it, however when it comes to running it in the browser I get the nasty error message saying:
'System.Web.Mvc.HtmlHelper<Adgistics.Mvc.ViewModels.Forum.IForumCreateOutModel>' does not contain a definition for 'ValidationSummary' and the best extension method overload 'System.Web.Mvc.Html.ValidationExtensions.ValidationSummary(System.Web.Mvc.HtmlHelper, string)' has some invalid arguments
The validation control will validate if I set the Display to Dynamic or Static, but it won't display the error text in the ValidationSummary when the onBlur event is fired (its fine if the form is submitted using the button). Does anyone know if this is a restriction of using the ValidatorValidate function or am I doing something wrong?
I'm currently working with the ASP.NET login control. I can set a custom failure text and I can add a literal on the page where the failure text is displayed if the login fails. I also have a validation summary on the page in which I collect all errors that can occur (for the moment it just validates that the user has entered a login name and a password.
It would be really nice if I could add the failure text of the login control as an item in the validation summary, but I'm not sure if this is even possible?
Hoping that the massive brainpower of stackoverflow can give me some pointers?
I have some custom validation that occurs outside of the built in ASP field validators and I want to update the contents of asp:ValidationSummary section in my document. Is this possible? Is there a reccomended method for doing it?
I am trying to make an AJAX Form work correctly with Client Validation, but I can't seem to figure out how to make it work together.Currently I have a view like this:
[Code]....
My model:
[Code]....
The client validation works on the Required and Stringlength attributes, but if I put an incorrectly formatted email, it still returns successful. Is there a special way to do the regular expression attribute? Or am I doing it wrong?
1) I have a createUserWizard and ForgetPassword Controls...I believe they don't have the Validation Summary Controls, but they throw out the error message(for controls like email validation etc) through ValidationGroup....now how do i throw the error message to the users as MessageBox(since i can't set the ShowMessageBox ="true" in ValidationSummary Control)???2) also i m checking the PasswordStrength at the web.config file.....When i m trying to throw the error message to the usersusing the Message Box....it doesn't actually throw the error message that i created(instead it throws me an MessageBox saying "new Password does not match the regular expression specified in the Config file
When my validation fires on my web form, the validation summary writes out the same error message for each control that was in error twice! I have no validation groups in my web form.Here is my html for the Validationsummary control.
<code>
<asp:ValidationSummary ID="ValidationSummary1" runat="server" DisplayMode="BulletList" ShowMessageBox="true" ShowSummary="false" EnableClientScript="true" HeaderText="You must enter a value in the following fields:" />
I have a text field where user can enter either an URL or an Email address. How can I use a RegularExpressionValidator to validate that user have entered an URL or an Email address
I had a question on here for a RegularExpressionValidator which I'm relatively new to. It was to accept all alphanumeric, apostrophe, hyphen, underscore, space, ampersand, comma, parentheses, full stop. The answer I was given was:
"^([a-zA-Z0-9 '-_&,().])+$"
This seemed good at first but it seems to accept amoung other things '*'.
