Web Forms :: Changing Values Of Input Type Hidden Tags - Dynamic Paypal BuyNow Button Using .net Codebehind?
Nov 26, 2010I have static html paypal buynow button that works great, but it's static.
[Code]....
But it is possible to change the values for the hidden inputs from .net codebehind code? I found this post which takes a different approach of sending these hidden fields instead as a query string to paypal. Not sure I like that though as would this not possiby explose some of those fields like the return page?
http://www.makaistudio.com/mksBlog/post/ASPNet-and-Paypal-buy-now-button-Offer-discount-at-checkout-in-code-behind.aspx
Basically what id like to do change the important parts of the button and info I'm sending to make it dynamic.I know I can do something like this in the markup, but that would mean having to fetch data mulitple times was hoping I could somehow adderss the field values directly in the codebehind. Or possibly dynaically generate and insert the entire changing input type fields from the codebehind
<input type="hidden" name="invoice" value="<%= getinvoice()%>">
Possible to add them with something like this: myform.Attirbutes.Add (???). If so how do I contruct these input types in .net?As far as return logic security, I've tested that it's solid, i just need to automate the button process so I don't have to create a buy now page and button for each product.

Web Forms :: Can Validate A Hidden Input
Apr 4, 2010I have an input...
<input
id="ratingField"
runat="server"
type="hidden"
/>
this hidden input is used by a star rating control. the user gives a star rating of 1 to 10 by clicking on the stars and some javascript detects which star was clicked and fills the input with the corresponding number.
I want to use a RequiredFieldValidator to ensure that the client has selected a star and if not return an error message to my validation summary.but the validator seems to be throwing an exception. How do I do this?
C# - Change Hidden Input With OnFocus Between UserControls?
Feb 15, 2011This is probably embarrassingly easy, but I've having problems getting this to work.
On ResidentAddress.aspx, I have 2 user controls (AppName.ascx and NavButtons.ascx). When a textbox in AppName.ascx has focus, I want to update a hidden input field on NavButtons.ascx with the value of "TRUE". In the codebehind page for NavButtons, I want to see what the value of this hidden input filed is.
This is what I have so far:
NavButtons.ascx
<input type="hidden" id="IpChangeFlag" name="ChangeFlag" runat="server" value="FALSE" />
AppName.ascx
<asp:TextBox ID="txtFirstName" runat="server" onFocus="document.getElementsByName('ChangeFlag').value='TRUE';">
NavButtons.ascx.vb
If IpChangeMade.Value.Trim.ToUpper = "TRUE" Then
MyValue = true
End If
I am unable to change the value of ipChangeFlad. It always has the value of FALSE.

VS 2008 - How To Read IFrame Hidden Input Value
Feb 9, 2012I'm using jQuery to build an IFRAME and pass some hidden input values to a Download.aspx page - jQuery code looks like this
Code:
$('<form action="'+ url +'" method="'+ (method||'post') + '" target="iframeX">'+inputs+'</form>')
.appendTo('body').submit().remove();
The inputs variable looks like this
<input type="hidden" name="filename" value="mit-license.txt" />
And the top of the Download.aspx code behind looks like this
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim ctx As HttpContext = HttpContext.Current
Dim response As HttpResponse = ctx.Response
Dim sFile As String = "mit-license.txt" ' Request.QueryString("filename").ToString
[Code] ....
I could not find the INPUT value - where does it pass in? I checked the "sender" and the ctx objects and could not find it... I hardwired the mit-license.txt filename to prove that the download works...
C# - Setting Hidden Input Value In JavaScript, Then Accessing It In Codebehind
Apr 21, 2010I have been trying to set the value of a hidden input by using Javascript and then access the value from within my C# codebehind. When I run the code that is copied below, the value that is assigned to assignedIDs is "", which I assume is the default value for a hidden input. If I manually set the value in the html tag, then assignedIDs is set to that value.
This behavior suggests to me that the value of the input is being reset (re-rendered?) between the onClientClick and onClick events firing.

C# - How To Receive Input To A Hidden Textbox And Submit A Form
Sep 6, 2010I have an ASP.NET application designed for a Windows CE device that needs to take in information from a scanned barcode. The device sends the scanned data as string input with a crlf to whatever field has focus. I set up my page with a textbox that takes the input and posts back to look up the item.
Now, I'd like that box to not be visible to the user, but IE complains when I set focus to it if the field is "visibility: hidden" or "display: none". I've tried moving it off screen using absolute coordinates, but setting the focus scrolls the window to the new location.

MVC :: How To Reference A Hidden Input Control's String Value In Controller Action Method
Jun 3, 2010 I'm using V.S. 2008 and asp.net MVC. I have a form in this page that user selects various items from Select controls.

Web Forms :: Access Html Hidden Input Field Embedded From Server Side Code?

How To Manually Set Button Input Type
May 28, 2010I have a jQueryUI dialog with some textboxes, plus a button. Right now, the asp:Button tag used to generate the button automatically sets its type as type="submit". The structure of the dialog is such that pressing enter at any of the textboxes should not call the button click event. It seems like the cleanest way to solve the problem, if it is doable, is to manually set the button's type to something other than submit. Is there a way to do this?
Edit: Forgot to mention this, but the button text is bound to a database item by <%# Eval() %>, which doesn't work without a server-side tag.

Jul 12, 2010As I understand it, the <input type=email> element in HTML5 will render as a simple text field in browsers that do not support the tag. On other browsers it will render properly, like on the iPhone it will bring up the e-mail keyboard layout.
like to use this in a project but my input fields are <asp:TextBox> controls. How can I use the HTML5 element but still access its data server-side like the rest of my fields?
File Browser Control To Replace - Input Type
Jun 17, 2010I'm working on an ASP.NET web application for our corporate intranet users. I have a form where a user should provide a path to the file on the local network (something like "localServersomeFoldersomeFile.ext") without uploading the actual file. The issue is that users don't want to type the whole file path and want to use some kind of visual browse dialog.
The standard HTML <input type=file> element allows to browse for a file, but most of the browsers (except for IE) don't allow to access file's full path, so I think it should be done by some external component like Silverlight, Flash, Java applet etc. I tried to do it with Silverlight, but I'm getting a SecurityException when trying to access file's full path using Silverlight's OpenFileDialog class. This java applet [URL] seems to do something similar to what I'm looking for, but it's focused on uploading files - I only need to be able to get file's full path and pass it to the server as a string.
