Validation Does Not Work For Web Usercontrol?
Sep 29, 2010
I have the following textbox with validation:
<asp:TextBox ID="txtInput" runat="server" Width="80px"
CausesValidation="True"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredValidator" runat="server"
ControlToValidate="txtInput"
Display="None"
ErrorMessage="Bitte füllen Sie dieses Feld aus"
Enabled="false" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator" runat="server"
ControlToValidate="txtInput"
ValidationExpression="[0-9]{1}(d)*"
Display="None"
ErrorMessage="Bitte geben Sie eine Zahl ein"
Enabled="false" />
<asp:ValidatorCalloutExtender ID="ValidatorCalloutExtender1" runat="server"
TargetControlID="RequiredValidator" />
<asp:ValidatorCalloutExtender ID="ValidatorCalloutExtender2" runat="server"
TargetControlID="RegularExpressionValidator" />
If I click on a button on this page (CausesValidation is set to true) then the control validates properly.
But when I put the textbox and its associated validators and extenders not directly on the page, but instead into a usercontrol then the validation-popup doesn't show anymore. It still seems to validate, because the action for the button is not triggered when the input is invalid.

Is there a way to disable request validation on an action without having to add the line <httpRuntime requestValidationMode="2.0"/> to Web.config? I'm currently posting XML to a controller action and get the "A potentially dangerous Request.Form value..." error. Is disabling request validation the only way to get the post to work, or is there some way I can intercept and encode the value that contains XML between the view and the controller action?

Iam trying to use a UserControl named CheckBoxControl as value for the ExpandControlID/CollapseControlID attributes of the CollapsiblePanelExtender. It works fine when I use a normal CheckBox instead.
<uc:CheckBoxControl ID="ucHaftpflicht" runat="server" OnCheckedChanged="UpdateStatus" ControlLabel="Haftpflicht" />
<asp:Panel ID="HaftpflichtPanel" runat="server">
</asp:Panel>
<asp:CollapsiblePanelExtender ID="CollapsiblePanelExtender" runat="server" CollapseControlID="ucHaftpflicht.CheckBox" ExpandControlID="ucHaftpflicht.CheckBox" TargetControlID="HaftpflichtPanel" />

I often use Placeholder control to dynamic load the UserControl. However there is a problem when i use, AJAX Control Toolkit not work on UserControl.
I would like for example a specific example as follows:
- This Project has 2 folder as "not use placeholder" and "Use placeholder". In folders have 2 file, default.aspx and uc1.ascx have the same content.
- In the folder "not use placeholder", I add CalendarExtender in uc1.ascx and run normally and in the folder "use placeholder" then CalendarExtender is not working.

I have some fields to be validated on the server (CustomValidator) which is in a separate user control and my Submit button is in the page not in the user control.
What I have done is, I placed all my Validation Methods in the code behind of my usercontrol (ascx.cs) and the page validation is in the code behind of the page (aspx.cs). I put them in the same ValidationGroupName (fields and Submit button). usercontrol (ascx) is a child of my page (aspx). I have already placed CauseValidation="true" to my Button and UseSubmitBehavior="true". The problem is it does not validate. What could be the problem in this?
Note: I cannot put the the Button to be part of the usercontrol.
Edit:in my aspx page, click event of the button has this.Page.Validate(ValidationGroupName) and all of my validators are on the fields on a separate control (ascx) which is a child of the aspx page.
protected void Button1_Command(object sender, CommandEventArgs e)
{
if(e.CommandName.Equals("Validate", StringComparison.Ordinal)) [code]....
The above snippet is located in my aspx page.I've tried to put the same button on the ascx page, it works fine. My thought is since the ascx page is under the aspx page. When the button event on aspx page is fired (Button1), the rest of the event in ascx page is not fired. I've tried to put breakpoints on the button event and validator events, if the button of the page (aspx) is the one I click, it will not stop on my validator events, if the button on the control (ascx) I click it will stop to the validator events. What could be the remedy for this?

Using the ValidationProperty I've managed to connect a RequiredFieldValidator with my custom control. When I enable client script in the validator, JavaScript errors occur.
Is there a way to tell the RequiredFieldValidator how it can validate my custom control in the client?

I have been playing with mvc for a few months now and one of the best things I thought was when there is validation errors the UPDATEMODEL method in controller is smart enough to automatically add errors to model state and return the view back to the input page with data entered and error message. Here is where I got a question - how does the controller put back the data that I entered initally? I looked for model, request and response object and none of them have the (invalid) data I entered. Here is an example of my general coding that I do:

I have an ASP.NET web app (with C#). In it I have a form with several fields and validators. For one of the validators I only need to validate when:
a certain textbox is empty and a certain record does not exist in the database (this is already handled).
I know I can't enable/disable the validator on page_load because something might be entered into that textbox. I also tried the following in the onclick event of the submit button but it didn't seem to work:
Validator1.Enabled = true;
Validator1.Validate();
I also tried Page.Validate() but that didn't work either...

I'm currently developping an application using MVC2 and Globalization (fr and de). I'm creating a form who use DataAnnotation on the model for validation, with localized error messages in my dataAnnotations.
Here is the trick :
I have two <input /> :
One for a required date (example : 12/05/2001) wich is a DateTime field in the model :
[Code]....
One for an optionnal hour (example : 22:30) wich is a DateTime? :
[Code]....
Erreur and LibellesSinistre are my ressources files.
I got two problems :
I can enter a date in my hour field and an hour in my date field.My error messages aren't localized.
Do I need a trick or something to make it work ?

Using MVC 3 RTM and MvcContrib/FluentHtml version 3.0.51.0, I can't get the jQuery client side validation to work. Server side validation works fine, and returns showing the correct validation summary, etc. But the form post always tries to hit the server-side post controller action when it should have stopped on the client side to display the validation error.
I tried replacing the MvcContrib ModelViewPage with the default Mvc ViewPage and it still didn't work.
Here's my code:
Web.config has:
[Code]....
Site.Master page has:

View page inherits from MvcContrib's ModelViewPage:Here's the view page:

I have studied Phil Haack's post [URL]about custom validation, however, I can not get this to work for my case. I need something like the "PropertiesMustMatch" validator in a default MVC2 project generated by Visual Studio.
None of my custom javascript gets called. I am registering the custom adapter in Application_Start using DataAnnotationsModelValidatorProvider.RegisterAdapter(....). In the DataAnnotationsModelValidator derived class, GetClientValidationRuls is never even called.
What is going on here? Maybe this type of validation where your validation attribute has to be applied to a class, not a propety, does not yet work with the RTM release of Visual Studio 2010.

I have a FileUpload Control on the page with validation and it is working smoothly.
Later there is an important demand to have it partially updated so we enclose it with UpdatePanel.
Then problem comes up when user browse file and press upload button, no file is uploaded.
Is it we cannot do partial rendering with FileUploader ?
