How can I pass parameters from silverlight(xaml page) to an aspx page without showing them on url link?
if I do this:
HtmlWindow hw = System.Windows.Browser.HtmlPage.PopupWindow(new Uri(path), "rptapp", options);
it will pass my parameters but they will appear in url.
I don't want to encrypt them...I just them not to appear there
Create a form in your page where you host the XAP file of your silverlight application and submit the form to the new url with the post method.
you fill the action attribute with your link and add input elements to it:
<form id="popupform" action="" method="post" target="_blank" style="visibility: collapse" enctype="multipart/form-data" />

In my web forms project (a forum) I have a form that is accessed through a link from another page, a link which includes parameters. for example:
EditPost.aspx?mid=0
When the page is loaded, the form hasn't yet been submitted and Request.QueryString contains the URL parameters I loaded the page with. However, after I send the form, Request.QueryString conatins the values of the form fields. This is a problem because I need the URL parameters after the form is sent.
The question is, how do i make the page send me those URL parameter with the form information?
If I'm approaching this wrong, and I'm supposed to keep the URL parameters from when the page is first loaded, let me know how.
Thanks!
Edit:
<form action="" id="f_editComment" name="f_editThread" method="post" onsubmit="return true;">
<%=ThreadTitle %>
<textarea id="body" name="body" runat="server"></textarea>
<input type="submit" id="submit" name="submit" />
</form>
I need to display a submission form inside a lightbox of an ASP.NET page.
If there is an error in the submission form such as user name not being unique, the postback then renders the ASP.NET page outside the lightbox.
How can I solve that problem?
Here is a code snippet of the .aspx page that includes the lightbox:
<...>
<p>
QunatumMotors is located in Detroit. Please use the link below to contact us.</p>
<p>
<!--START CONTACT FORM OVERLAY-->
<!-- first overlay. id attribute matches the selector -->
<a href="**../informational/contactform.aspx"** rel="#overlay" style="text-decoration:none">
> Click here to contact us
</a>
<div class="simple_overlay" id="form_contact">
<!-- overlayed element -->
<div class="apple_overlay" id="overlay">
<!-- the external content is loaded inside this tag -->
<div class="contentWrap"></div>
</div>
</div>
<!--END CONTACT FORM OVERLAY-->
<p> </p><p> </p>
<...>
contactform.aspx is just a standard .aspx page with form fields, field validators, label to display errors (e.g. username not unique) and submit button.
When a postback occurs on contactform.aspx then (of course) it is rendered outside the lightbox. How can I display the postback of contactform.aspx inside the lightbox?
Thanks for your help!
The lightbox content isn't like another tab or window: it becomes part of the host page.
In other words, it incorporates the HTML generated by contactform.aspx into the host page's document object model (DOM). Activating the lightbox adds a form to the host page that posts to the contact page:
<html><body>
<!-- host page content here -->
<!-- contact form content -->
<form action="contactform.aspx">
<!-- text boxes, buttons, etc. -->
</form>
</body></html>
When the user submits, their browser issues a new request: a POST to contactform.aspx. That request returns the contact form's HTML.
There are several ways you might work around that:
Use ajax to perform the update asynchronously. (You might even be able to do this by using an UpdatePanel in contactform.aspx, but I don't use them much anymore and haven't though that through).
Convert contactform.aspx into a control (if you're using it in several places) and embed it in the host page.
At the end of the contact form's submit handler, redirect to the host page with a flag that instructs the page to immediately activate the lightbox. (This has numerous issues and sounds pretty fragile ... but it's plausible.)
Is there a good way to enable forms that come out of user content (CMS) that is displayed inside the form runat="server" tag? All sorts of services provide forms for users to paste into their website, which break if the content ends up inside a .net form. It seems to me that there must be a good way around this, but I can't seem to find any solutions.
The one solution I've found is to put them in an IFRAME. So instead of embedding your form inside the page:
<FORM action="http://www.example.com/target.html">
.. form content
</FORM>
create a new ASPX file like this:
<FORM action="http://www.example.com/target.html" target="_top">
.. form content
</FORM>
Then in your original page, you'll refer to it via an IFRAME:
<IFRAME src='myform.aspx'></IFRAME>
Some things you'll need to do:
Make sure that you do not include any <FORM runat="server"> inside the new ASPX file.
Adjust the size of the IFRAME and the ASPX file to be exactly the same
For the FORM in the new ASPX files, you probably want to set target='_top' to ensure when a user fills in the form, the result is in the main window rather than inside the IFRAME.
I have an asp.net page in an iframe where all links target _blank
<base target="_blank" />
But I want the form on it to submit to _self (i.e. the iframe where the page is located) when the one button is clicked. The form is an <asp:Panel> with an <asp:Button> control for submitting it.
Where can I set the target for this form? Since there isn't a <form> tag or an <input> tag in the file (ASP.NET makes them when it renders the page), I don't know how to change the target to override my <base> tag.
I'm not sure if I understood you right, but you can set the target in the form tag, like this:
<form method=post action="Page.aspx" target="_self">
I just found this post on the asp.net forums by mokeefe that changes the target by javascript.
I just put it in my page and tried it. I had to make these modifications:
1. I'm using asp tags only, so I have <asp:Button> not <input type="button"> and my onclick has to be the server-side method I'm calling on submission. Therefore I put this new javascript in OnClientClick:
<asp:Button ID="cmdEmailSearch" runat="server" Text="Search"
OnClick="cmdEmailSearch_Click"
OnClientClick="javascript:pageSubmit()"/>
2. I removed the myForm.submit() since ASP.NET renders the page putting the WebForm_DoPostBackWithOptions() javascript in the button's onclick right after it puts my pageSubmit()
<script type="text/javascript">
function pageSubmit(){
// where form1 is the Parent Form Id
var myForm = document.getElementById('form1');
myForm.target = '_self';
}// end function
</script>
I want to upload a file using asp.net so I do not want to post back the page while uploading . How can I do that and is there any way to do it using Ajax .
Make the file upload form target a hidden iframe.
<iframe name="UploadTarget" style="display:none"></iframe>
<form target="UploadTarget" action="postfile" method="post" enctype="multipart/form-data">
<input type="file" name="MyFile">
<input type="submit" name="submit" value="Send me a file">
</form>
The final trick is to add to your response page:
<script type="text/javascript">parent.somecallbackfunction("Here is some data")</script>
To let your parent page ( the one containing the hidden iframe) know that the the file upload has completed.
An iframe can be placed on your page and can contain an input element, type=file. You can manipulate and submit the iframe form via javascript. You can hide the iframe by setting its CSS style to display:none. This is generally known as the hidden iframe method.
Use something proven like SWFUpload and save yourself the time of writing your own client code.
