C# - ViewState Doesn't Work When Control Become Enable=False
May 26, 2010Why when a control does contain value but it's set to .Enable=False that all controls become disable (that's ok) but why that the ViewState doesn't retain the data on the next post back? If I get the UserControl without modifing its Enable state, the ViewState work between post back.
How can we disable a UserControl that all its control become disable (this part work) but all of them KEEP use the ViewState (this doesn't work)?
Clarification:
1)In the aspx.cs click button EDIT:
myControl.Enabled = false;
//This produce to have all controls in myControl to be disabled.
2)In the asp.cs: click Save to leave the EDIT state:
myControl.Enabled = true;
//This produce that all controls inside myControl are blank : no viewstate!
Other postback works because we do not put myControl.Enable to false.

View 4 RepliesSet ValidateRequest To False?
Nov 2, 2010I'm using FreeTextBox HTML editor in some webforms in my asp.net project . if I do not set ValidateRequest property to false I get this error :
A potentially dangerous Request.Form value was detected from the client
It's OK in admin folder though , Because only authorized users have access to work with it . But how about public pages like sections where every users have access to leave comments(using FreeTextBox for collecting users comment ) ? Isn't risky for XSS Attack ? If the answer is not Yes , So what's ValidateRequest property for?
MVC 3 ValidateRequest (false) Not Working With FormCollection
Dec 5, 2010FYI I am using .NET 4.0 / MVC 3. In my controller, the following is my code:
[HttpPost]
[ValidateInput(false)]
public ViewResult Edit(ContentTemplateView contentTemplateView, FormCollection collection)
Everything works fine when I don't enter HTML, so I know the proper controller is being fired. Also, I have following set properly in my web.config files:
<httpRuntime requestValidationMode="2.0"/>
I only get this problem when I include the FormCollection (which is needed for this particular Controller). So what exactly am I doing wrong? [I have done what was proposed on the following questions, and they work as long as there is no FormCollection. None of them offer a solution with an included FormCollection] Why is ValidateInput(False) not working?

Form Validation - OnClientClick="return False;" Doesn't Work
Oct 8, 2010I just want to add some client side (JQuery Javascript) validation in a web user control. I put an OnClientClick handler and the function gets called. BUT, even if I return "false", the OnClick method always get fired. What am I doing wrong ?
I'm with VS 2010, targeting the 4.0 framework with JQuery 1.4.2. and JQuery UI 1.8.4.
Here's a sample code :
<td style="text-align:right"><asp:Button ID="btnAddSave" OnClientClick="return ValidateMail();" OnClick="btnAddSave_Click" runat="server" Text="Submit" /></td>[code]...
If I put a breakpoint in the Page_Load event, I see that I get in and the btnAddSave_Click event is also executed.
A Potentially Dangerous Request.Form Value Was Detected / Can't Set ValidateRequest="false"
Aug 16, 2010I'm using a php script to http post some xml files to a .net URL.
When I submit I get the response:
A potentially dangerous Request.Form
value was detected from the client
(<?xml version="...UTF-8"?> <!DOCTYPE
cXML SYSTE...").
Description: Request Validation has detected a potentially dangerous client input value, and
processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.
As I'm not using .NET I can't set ValidateRequest="false" in web.config.
Do I need to sanitize my xml before submitiing? How can I do this?
Web Forms :: Getting The "Potentially Dangerous Request Form..." Error Even With ValidateRequest Set To False?
Jun 25, 2010I have an app that was originally running fine in ASP.Net 3.5, using the ValidateRequest set to false to allow HTML to be saved from a rich text box. However, after converting the app to 4.0, I am getting the Potentially Dangerous message, even though both the page and web.config have the value set to false.
I went into the page and created a PagesSection object and checked its value and then set the value to false. Everytime the page is hit (postback or new) the value is always returned as true, until I set it to false. Not sure why it is reverting to true.
C# - FCK Editor + Update Panel + ValidateRequest="false" ?
Mar 8, 2011When I set fckEditor to Some Value like
fckDescription.Value = "Description Text";
It creates problems such as Update Panel not doing Async PostBack for DropDownList control and gives error when DropDownList selection changes:Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
But when I Comment out these lines
// fckDescription.Value = "Description Text";
It Works Fine... I am wondering why it is so !!?!!
Also, fckEditor is outside UpdatePanel and DropDownList Control is inside UpdatePanel.

ValidateRequest ="false" For Single Input?
Mar 18, 2010I'm wanting to allow users to enter HTML in only a single textbox. I understand it's possible to change ValidateRequest in the Page directive to false in order to remove protection.I'm guessing that this allows HTML to be entered in any textbox on the page. Is there anyway to apply ValidateRequest=False on only a single control?
View 3 RepliesC# - ValidateRequest="false" Is Acting Wierd?
Apr 4, 2011(ASP.NET 4.0 C#)
I have my <httpRuntime requestValidationMode="2.0" /> in the webconfig. AndI have my validateRequest="false" in page directories.On one page, I send some data (html) from a ckeditor (textarea) to a database. Works fine.On another page I fill the ckeditor with data from a database, then I update it (send it back), and I get the famous "A potentially dangerous Request.Form value was detected from the client."
Makes me very confused. The only difference is that on the second page the data gets dynamically inserted into the textarea, where on the first page the textarea is empty on pageload. Am i missing something here? Im pretty sure Encoding/decoding doesnt mean anything, as the framework stops it before I can even start messing with it on the backend.

Button1.Disable=false Doesn't Happen Immediately?
Dec 13, 2010I have a Wizard which has a FileUpload in one of the steps. It also has an "Upload" button. When the user browses to a file, and clicks Upload, I upload the file into SQL.
There seems to be some synchronization problem for very large files, and I would like to disable the Wizard's Next button until the Upload of the file to SQL completes. It can take a while, especially on a wireless PC.
In my OnClick event for the Upload button, I am trying to disable the Next button. The code, which is below, appears to be correct, but the Next button doesn't actually disable until the Query completes. Can I get the Next button to disable immediately instead of after the SQL Update completes?
Here is my code:
Protected Sub JustificationDocUploadButton_Click(ByVal sender As Object, ByVal e As EventArgs) Handles JustificationDocUploadButton.Click
If RequestJustificationAttachment_FileUpload.HasFile Then
Dim obj As Object = Wizard1.FindControl("StepNavigationTemplateContainerID")
Dim startButton As Button = obj.FindControl("StepNextButton")
startButton.Enabled = False
SqlDataSourceJustificationAttachment.Update()
End If
End Sub
