View 6 RepliesI'm very much a newbie to ASP.Net and am getting the "a page can only have one server-side form tag" error. I have searched the internet for clues, but my understanding (or lack of) means I can't adapt other peoples solutions to resolve my problem.My master page has the following code:
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>
I m getting this error......
HttpException (0x80004005): A page can have only one server-side Form tag.
I have a function in my asp.net page and whenever it is called it is giving me an error
"A page can have only one server Form tag"It doesn't happen when the page is loaded.only after a button is clicked.
The code is:
void send(object sender, EventArgs e){
StringBuilder sb=new StringBuilder();
StringWriter sw= new StringWriter(sb);
[code]...
I am using master page and when i run this page it show error message which is mention below: a page can have only one server-side form taghow can i solve or fix this problem.
View 3 RepliesI have Master Page and ascx user controls in my application.
how would I use the Cross-Page technique using the @ PreviousPageType directive.
useful links or samples to achieve this.
I am trying to use the Page class that exposes a property named PreviousPage from my User Control.
I have a web form called default.aspx which has a form with user information. In addition to this, I have an iFrame on the same page that displays a page Secondary-Form.aspx that has a few additional dynamic data fields. I need to do two things.
1. I need to pass the parent form data in real time to the iFrame page to refresh its content and modify it's fields accordingly. Example: If the user submits their Vehicle Choice as Car on parent form, the form item in iFrame will display a radio button that says Honda, and if the user submits their Vehicle Choice as MotorCycle in the parent page, the iFrame will display Harley Davidson as the radio button choice
2. The submit button is on the parent page. I want both pieces of this information (from the parent page, as well as iFrame selection) to be passed to a server side ASPX page to process this information.the default.aspx and Secondary-Form.aspx files are located on different domains.
i need to create a dynamic form that switches the contents of the page without reloading or refreshing the page.

View 4 RepliesI'm trying to upload files to Amazon. In their simple example, it's an HTML page with a bunch of hidden fields that pass the data needed. The problem is when I create that form in ASP.NET, I, inevitably, end up with a few extra hidden fields i.e. __VIEWSTATE and __VIEWSTATEENCRYPTED at the very least -- and that after setting EnableViewState to false on the page. No matter what I do, these two hidden fields are there. I've read some articles that indicate that I have no way of removing them from the page unless I can remove the <form runat="server"> all together.
I can imagine what the answer will be but I have to ask: is there a way to remove the form tag from an aspx page?
I assume the answer will be "No". Then my follow up question is: how am I going to upload a file to Amazon S3 using an aspx page?
Now, some may suggest that I should use a simple HTML page. Then my issue would be this: there are a whole bunch of parameters I need to get by making an API call first -- they're the ones that end up in those hidden fields. How can I upload my files without losing this server side functionality that I need in order to make the API call?
Here's what that upload form looks like -- according to Amazon:

Currently whenever I need to send a request to a payment-gateway, for example, I redirect my page to another page on my website which has a form with several hidden fields. I then pre-populate the values of these fields server-side, and specify in the body tag something like 'onload="form.submit();"'
However, I'm wondering, rather than redirecting to this page, is there anyway that all this data can be collected and POSTed to the payment-gateway server-side?This will cut out the need to redirect the user to this blank page, and make everything a bit more tidy.
I have a 2 page signup form, on each page the form fields are seperated into sections. Each section is a user control, and there are 2 controls on each page. My question is, how do I get the data from page A to B. I'll be using a webservice to insert the data into SQL so I'm not worried about that portion of the process.

using System.Collections.Generic;

Suppose the user is on ..../paycheck.aspx which is the content page. But when ...../paycheck.aspx loads, "lnkDynamic" properties "Text and PostBackUrl" must be set. Which events should be handled .....
I have a form that works just fine, problem is that if user leave form open for more than 20 30 min and then click a button on that form the browsers status line shows "Error in page", user then must refresh the page in order for the page function.
View 1 RepliesI have a master page with a form on it. It's a people search form. When the user clicks on the search button it goes to the search results page that uses the same master page. With the code below I get the info off the master of the current page. Howdo I grab that info from the first page?
Here's the code:
Master page:
< FORM id=formEmpSearch method=post action=~/About/peopleSearch.aspx runat="server">
< asp:TextBox style="WIDTH: 153px; HEIGHT: 12px" id=txtSearchName onfocus="this.value=''" runat="server" CssClass="searchBox">
Master Code Behind page:
Imports System
Imports System.Web.UI
Imports System.Web.UI.WebControls
Partial Class mstrIntranet
Inherits System.Web.UI.MasterPage
Public Property mSearchName()
Get
Return txtSearchName.tex
End Get
Set(ByVal value)
txtSearchName.text = value
End Set
End Property
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
txtSearchName.Text = "People Search"
End Sub End Class
Search Results Code Behind page:
Partial Class PeopleSearch2

I have an ASP.NET Web Site hosted in the _layouts folder of a SP2010 site. One of the pages contains a server-side form and works fine until I try to set its master page to a Sharepoint master page (specifically a modified v4.master) to achieve a consistent look & feel. I've placed my original page content within <asp:content> tags but it now throws an "A page can have only one server-side Form tag" error. I know that ASP.NET pages can only contain a single server-side form but what walkarounds can I use to stop Sharepoint from throwing this error?
View 1 RepliesI have an HTML page witht the following details:
<form action="formprocess.aspx" method="POST" name="form1" id="form1">
When the users presses submit, I get the below error and for the life of me cannot figure out why!
I have tried GET as well, byt that just seems to post to itself and just puts the form vairables in the URL rather than going to formprocess.aspx.page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access.Please try the following:Contact the Web site administrator if you believe that this request should be allowed.Make sure that the Web site address displayed in the address bar of your browser is spelled and formatted correctly.HTTP Error 405 - The HTTP verb used to access this page is not allowed.Internet Information Services (IIS)
I have a select box in an asp.net form like so:
[code]....
This way I can set a session variable with the same name in Process.aspx:
[code]....
, and then set the value of the select box when the user returns later like so:
string referer = (string) Session["referer"];
foreach (ListItem i in refererSelect.Items)
if (referer == i.Value)
i.Selected = true;
The problem is when the form is sent to the server, the form key gets changed to "ctl00$content$refererSelect". Is there any way to fix this?
I have a Web User Control I created for authentication. The web user control is inside the box below. Clicking any button (1 or 2) below works correct as it goes to the correct c# button click event in the code behind file. If I press enter on fields a or b it goes to the correct callback (button1's) if I press enter on field c it still goes to button1's callback, not button2's
How can I give my web user control a nice self contained for and view state etc, so it wont mess with the remainder of the page's form?
+--------------+
| User: __a___ |
| Pass: __b___ |
| [button1]|

Prompt:______c______ [button2]
we host a database for several users. We allow the users to host the login form on their own server. The form calls an ASP page that we host, which executes a stored procedure to authenticate the user.
We are in the process of moving to ASP.net. The "Forms" authentication method appears to only work if the login page is hosted locally. Is there a way to use Forms Authentication & allow the login form itself to be on a different server. I'm looking for a tutorial somewhere that will get me pointed in the right direction

View 1 RepliesI want to be able to post my form data to another page based on the result of a validation done on server (and not via javascript). As an example, let's say the user captures a customer number and then captures the phone number of the customer on page A. When the user clicks on the submit button, the page posts back. Then, in the button click event, I need to check in the database if the customer number exists. If it exists, I need to post the data to page B so that user can input the next information. If it does not, I need to stay on the first page and show an error message telling the user that the customer does not exists.
I do not want to use Response.Redirect cause that would mean that page B would lose the form data coming from page A. I know about crosspage postbacks but that just turn the problem the other way around (if I post directly to page B, how do I get back to page A with the form data and show the error message?)...I know about Server.Transfer too but I would like to avoid that method because I know there are down sides to it too...I tried setting the button target URL to page B after validating from the database but it does not automatically redirect to Page B, it still shows up Page A and then if you click again on the button you are taken to page B. I know I could setup a javascript to automatically call the click on the button to post the page the second time automatically to the Page B but I don't like that method (if the user has slow internet, he sees the page twice and once the user is on page B, he can't use the back button cause he would be automatically redirected back to Page B because of the script).So, is there a way to change the request target after the button's click code has been handled???
Is it possible to obtain another aspx page's form ID from current page?
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
HtmlTextWriter ht = new HtmlTextWriter(sw);
form1.RenderControl(ht);
From here, is it possible that form1 is another page's form1 ID?
