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'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.
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 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 Replieswhat is difference between server side submitting and client side submitting a form.
Can any one explain with an example.
Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).

I've recently implemented a simple dynamic forms engine that uses dynamically loaded ASP.NET controls in concert with an EAV schema to handle the variable nature of the data model. The business was sufficiently satisfied with the end product for a time, but is now clamoring for much more complex dynamic forms:Field visibility is tied to the values of other form fieldsList of drop down possible values tied to the state of other form fields Enforcement of various business rules across the for
View 1 RepliesI have recently been investigating methods of creating web-based forms for an ASP.NET web application that can be edited and managed at runtime. For example an administrator might wish to add a new validation rule or a new set of fields.
The holy grail would provide a means of specifying a form along with (potentially very complex) arbitrary validation rules, and allocation of data sources for each field. The specification would then be used to update the deployed form in the web application which would then validate submissions both on the client side and on the server side.
My investigations led me to Xforms and a number of technologies that support it. One solution appears to be IBM Lotus Forms, but this requires a very large investment in terms of infrastructure, which makes it infeasible, although the forms designer may be useful as a stand-alone tool for creating the forms. I have also discounted browser plug-ins as the form must be publicly visible and cross-browser compliant.
I have noticed that there are numerous javascript libraries that provide client side implementations given an Xforms schema. These would provide a partial solution but server side validation is still a requirement.
Another option seems to involve the use of server side solutions such as the Java application Orbeon. Orbeon provides a tool for specifying the forms (although not as rich as Lotus Forms Designer), but the most interesting point is that it can translate an XForms schema into an XHTML form complete with validation. The fact that it is written in Java is not a big problem if it is possible to integrate with the existing ASP.NET application.
So my question is whether anyone has done this before. It sounds like a problem that should have been solved but is inherently very complex. It seems possible to use an off-the-shelf tool to design the form and export it to an Xforms schema and xhtml form, and it seems possible to take that xforms schema and form and publish it using a client side library. What seems to be difficult is providing a means of validating the form submission on the server side and integrating the process nicely with .NET (although it seems the .NET community doesn't involve themselves with XForms; please correct me if I'm wrong on this count).
I would be more than happy if a product provided something simple like a web service that could validate a submission against a schema. Maybe Orbeon does this but I'd be grateful if somebody in the know could point me in the right direction before I research it further.
I have a webpage with a form below -

I was wondering if there is an easy way to submit a form or a collection of fields with jquery and json to a C# server-side script. I was thinking of a script that retrieves all data from elements with an attribute called 'form' (yes, we just add a new attribute to for example a textbox or textarea). Thus, the script searches for all form attributes with form='myform' and then submits the data as an form object. In server-side code we know how to deal with the data. Does someone has such a script? Or can I inspire someone to develop such a script? (I have the idea, not the skills) ..also, sessionstate needs to be available (cookie).
View 8 RepliesI've got an ASP.NET 3.5 Web Forms application in which a large chunk of code needs to be duplicated between a few different pages. Sounds like the ideal candidate for a user-control right? Problem is, this cannot be contained within a <form runat="server"> because it contains a client-side form of it's own. There are no runat=server controls or postbacks or anything that really need that webform - think of it just as a chunk of HTML with a few basic <% %> tags. I'd just want to set a property on the control when it's loaded, so that it knows what to output. This is purely an exercise to make the code easier to maintain.Before I resort to using an oldskool <!--#include-->, is there some better way of doing this?
View 5 RepliesI've searched high and low for a efficient and reusable way to detect, on a postback/server-side, if any input controls on a form have been changed and I haven't found anything other than client-side solutions such as DirtyUpdatePanelExtender. I've come to the conclusion that it must be either really simple or really complicated.Ultimately what I want to do is to perform a database update, or not, depending on whether or not the user has changed any input controls on the form. The only thing I've come up with so far is to save the original values as Viewstate variables and then compare them with the Request values on a postback, but that seems far from ideal.

View 1 RepliesI am trying to allow for multiple selection check boxes that are created dynamically.
The Following code is written for each row in the dataTable (I print it as HTML code)
