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:-
[Code]....
my controller code looks like this:-
[Code]....
my view code looks like this:-
[Code]....
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.
css
.form-box .form-error-box {
background: #cd3300 url("../../../images/alert.gif") no-repeat 10px 10px;
color: #ffffff;
font-weight:bold;
padding:10px;
padding-left: 80px;
min-height:55px;
}
code
<asp:validationsummary id="vSummary" cssclass="form-error-box" displaymode="BulletList" headertext="An error has occured" runat="server" backcolor="" forecolor="" />
This works in Firefox and IE 8 on post but not IE 6. Unfortunatly I have to support IE 6
I am trying to do a simple validation where i check the text box value. I have used follwing approch.
<%: Html.ValidationSummary(true) %> in View.
[Required (Error Message="Name Required")]
public virtual string Name{get;set;}
but in my controller if i enter a blank value in txt box then still the ModelState.IsValid is property is etting true.
I want to validate my different pages so I use System.ComponentModel.DataAnnotations to do that But I have a problem with that:
[Code]....
[Code]....
this.RegEx = RegEx;
this.ErrMsg = ErrMsg;
}
}
}
But I have this problem :

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.
[Code]....
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#
View 2 RepliesI 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'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
I'm trying to get a textbox to validate onblur. I have the following code:
myPage.aspx:
<asp:TextBox ID="txt1" runat="server" /> <asp:Button ID="btn1" runat="server" Text="Submit" OnClick="SubmitForm"/>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="No text" ControlToValidate="txt1" Display="None">
<asp:ValidationSummary ID="ValidationSummary1" runat="server" />
myPage.aspx.cs:
protected void Page_Load(object sender, EventArgs e)
{
txt1.Attributes.Add("onblur", string.Format("CheckForValue('{0}');", RequiredFieldValidator1.ClientID));
}
protected void SubmitForm(object sender, EventArgs e)
{
if (Page.IsValid)
{
// process ...
}
}
myPage.js:
function CheckForValue(sender) {
var control = document.getElementById(sender);
ValidatorValidate(control);
}
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'll try to make it short. I have two validation summarys on one page (one for the LOGIN and one for the REGISTER).
But when i click on the LOGIN button, it shows not only the missing fields from the LOGIN part but also the ones from the REGISTER part.
I was woundering if I could use two validations summaries without that problem ?
And if no, is there any alternative ? Like how do all the websites in Asp.NET do to have two forms or more per page ?

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
View 8 RepliesI 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 '*'.
I am trying to use the RegularExpressionValidator Control in Visual Studio to validate a textbox for email address expressions.

I have tried the same mechanism before and have worked; however, this time I am on a new machine, WinXP Pro running IIS v5.1.
