Web Forms :: HttpWebRequest Bypass Javascript Redirection?
Feb 20, 2010
I just wonder if there is a way HttpWebRequest can bypass redirection made by javascript?For example, I use HttpWebRequest to hit [URL]
[Code]....
Instead of getting redirected to the page: http://office.microsoft.com/en-us/default.aspx, with http return code of 302 before the redirect.I got the html of the page, with <noscript> part of: If this page does not automatically redirect, you have scripts disabled. The http return code was 200.I know that the reason why HttpWebRequest does not handle the redirect is because it does not execute scripts like a browser. So I just wonder if there is a way to do this without using a browser?

i have a gridview with commandbutton column and a textbox template column. My requirement is changing the text and hitting the enter key should also perform the same function as the command button. So i enabled the autopostback of the textbox.But if i click the command button after changing the text in the text box fires both the TextChanged event as well as the item command event. Is there anyway to bypass the Textbox text change event if i postback using the grid command button?

I used the gridviewhelper to group the rows in a gridview.
[Code]....
Each row as two itemtemplate, each one with a checkbox.
[Code]....
I'm having some problems when i search for the rows that have a checkbox checked.
[Code]....
I see when debugging, that for some reason the checkbox is checked in the row that have the groupheader, and then, in the row that is effectibly selected, the checkbox is not checked. So, in few words, how can i bypass the groupheader row and only search the checkboxes in the other rows.

I have multiple sub-domains that use forms authentication. Once a user logs in, they are fine going to any of the other sub-domains.
Here is my problem: If I go to [URL], I get redirected to [URL]. After entering my credentials, I get redirected to [URL], which doesn't exist.
I have a work around but I would like to know if there is a cleaner way. What I do currently is set the loginUrl attribute of the forms element of the [URL]to be [URL]
Then, in the login.aspx code, after I've authenticated and set the cookie, I look to see if there was a domain variable passed in to the URL. If so, I prepend the returnUrl with the domain and do a simple redirect.

I have a small gridview containing two columns: "modeluserid" and "modelid". It fills out nice.
[Code]....
Now, I want that when the user selects a row, he is automatically getting redirected to another page.
For example: (/Evaluationform.aspx?modeluserid=1&userid=1)I've used this code in the c# behind:
[Code]....
The url is generated on each click and the userid variable in the url is correct.
The only problem is that the modeluserid always stays the same for each url? ("1", first value in the table). Does someone know what I am doing wrong with the modeluserid variable?
Is it also possible that the user has to "select" the row instead of an "onclick" on the entire row?

I would like to know if it's possible to bypass the validation of one property which is using Data Annotations. Since I use the model across multiple pages, there's a check I need in some, but not in others, so I would like it to be ignored.

Scenario: I have a bunch of web applications for which I want to add a simple ping functionality via http handler. Example: [URL]
Problem: For some of the applications this approach does not work becasue of custom HttpModule. These modules have some depedency on either authentication or some other processing logic due to which it makes the request invalid.
I am trying to find a solution to get this ping functionality work without making any changes to existing HttpModules.

I am trying to bypass the ConfirmButtonExtender depending on the value of another field in the page. Basically, when a user click on my "Cancel" button, I normally display a modalpopup using the confirmbuttonextender and the modalpopupextender to display a dialog box confirming that they wish to cancel any changes they have made and return to the prior screen. If they click Yes, the button's onclick event fires which calls some code in the codebehind and redirects the user to another page. If they click no, it just returns to the same page, with no changes. However, in some situations, I know that my user is unable to perform any edits (they aren't allowed to) and for those users, I don't want to display the "Are you sure you want to leave you will loose any changes" dialog box. I've set a hidden checkbox field named "cbAllowEdit" to indicate whether the user is allowed to edit the fields or not. I was trying to use the technique found at link text to get this working but it just doesn't even seem to be firing the button's onclientclick event at all.
ASPX & Javascript
<asp:CheckBox ID="cbAllowEdit" runat="server" Checked="true" />
<asp:Button ID="btnCancel" runat="server" CausesValidation="false"
OnClick="btnCancel_Click" Text="Cancel" OnClientClick="disableSubmit();return false;" />
<ajaxToolKit:ConfirmButtonExtender ID="ConfirmButtonExtenderbtnCancel"
runat="server" DisplayModalPopupID="ModalPopupExtenderbtnCancel"
TargetControlID="btnCancel" BehaviorID="ConfirmButtonExtenderbtnCancel" />
<ajaxToolKit:ModalPopupExtender ID="ModalPopupExtenderbtnCancel" runat="server"
BackgroundCssClass="modalBackground" CancelControlID="btnCancelCancel"
OkControlID="btnConfirmCancel" PopupControlID="ConfirmCancelPanel"
TargetControlID="btnCancel" />
<asp:Panel ID="ConfirmCancelPanel" runat="server" CssClass="modalWindow"
Height="200" Width="450">
<p class="confirmMessage">
Are you sure you want to navigate away from this record?
</p>
<div align="center">
<p class="feedbackError">If you have made any changes to the record since the last time
you saved, they will be lost.</p>
<asp:Button ID="btnConfirmCancel" runat="server" Text="Yes" Width="75" />
<asp:Button ID="btnCancelCancel" runat="server" Text="No" Width="75" />
</div>
</asp:Panel>
<script type="text/javascript">
function disableSubmit() {
if (document.getElementById('<%= cbAllowEdit.ClientID %>').checked) {
return checkSubmit();
}
else {
return true;
}
}
function checkSubmit() {
var confirmButton = $find('ConfirmButtonExtenderbtnCancel');
confirmButton._displayConfirmDialog();
}
</script>
Code behind:
/// <summary>
/// Runs when the btnCancel button is clicked.
/// </summary>
protected void btnCancel_Click(object sender, EventArgs e)
{
Page.Response.Redirect("~/Searches/LookupCode/Default.aspx");
}

I am updating a website for a client. I am adding a module to it which uses the same username and password as the main site and has a link on the main admin page. But has a different admin page. I was wondering if I could use a session state variable to let the client automatically login to the module if he is already logged in to the admin page and how would I go about it?Secondly,I have 4 master pages setup. Two for the main website and Two for the module inside the website. Since the module is a separate app. Is there a way I can still nest the master pages to give the module a same look as the website. Other than creatings separate css files and then restarting the whole procedure.I get this error " The virtual path '/Website/MasterPage.master' maps to another application, which is not allowed."

Before spening anymore time researching this, I'd like some opinions.I inherited a .Net application - and I won't even mention that the previous owner built it using inline code and removed the code behind pages - so I have a LOT of fixing to do, including adding a data access layer.But, there is a login control and this sets the MembershipUser.There is a second app, written in ColdFusion, that I am passing one variable to the .Net app.We need one login for both apps. So, the CF is logged in and goes to the .Net app.I can check this var and see if the user exists but need to log the user in and set roles and Membership but bypass the login of the login control.

I need to scrub data for malicious content in a form (whose website is UTF-8 encoded) so I'm doing the following:
myTextBox.Value = System.Web.HttpUtility.HtmlEncode(value); where value is the data to be placed in the TextBox.This does correctly scrub malicious data such as Javascript calls, but also turns Japanese characters into their UTF-8 equivalents, such as 愛
Is there a way to skip those characters from being encoded, like some sort of range?

I have a simple search user control that consists of a textbox. The textbox's onchanged event appends the entered text to another page address and response.redirects to that page. The target page reads the query parameter and displays the results. Works great the first time a search term is entered. The problem comes if I immediately enter another search term, instead of refreshing the search results page with the new query parameter, it jumps back to my default.aspx page. I'm not sure where its getting that as an address to redirect to, the only control with default.aspx as a target is a imagebutton on my master page. I've tried turing off the autopostback on the textbox but it didn't help the problem.
Here's the search user control

i have a form on a particular ASPX page that has custom js validation. Also on this form is a navigation menu in the header.
The navigation menu items are built programatically and are initiated by __doPostBack calls which obviously submits the form.
The problem i am having is that the form itself has code something like the following
onsubmit='return validateForm()'
and if the form has not been filled out then the form cant submit. This in itself is not a problem unless a user goes to the form but decides to navigate away.
When this happens the validateForm function fails.
Does anyone have a workaround for this issue?
NB: On my nav links i have already set CausesValidation="False"
This is the markup:
<div id="divNavigate" class="absolute_topleft">
<asp:LinkButton ID="linkGoHome" runat="server" OnClick="linkGoHome_Click" CausesValidation="false" CssClass="xxx">text.</asp:LinkButton>
</div>
This is the handler:
protected void linkGoHome_Click(object sender, EventArgs e)
{
Response.Redirect("xxxxx");
}
This is the validation function:
[Code]....
And this is how its called:
<form id="formLogin" runat="server" onsubmit="return validateTextField(field1)">

I am developing a web page that needs to display, in an iframe, a report served by another company's SharePoint server. They are fine with this. The page we're trying to render in the iframe is giving us X-Frame-Options: SAMEORIGIN which causes the browser (at least IE8) to refuse to render the content in a frame. First, is this something they can control or is it something SharePoint just does by default? If I ask them to turn this off, could they even do it? Second, can I do something to tell the browser to ignore this http header and just render the frame?
