Dreaded Must Be Placed Inside A Form Tag With Runat=server In Workround?

Nov 30, 2010

I have a user control that employs many other controls (GridView, Images, Ajax Tool kit extenders, etc.). When called the RenderControl() method there is the dreaded "<control> must be placed inside a form tag with runat=server". Seems many people have run into this and suggest overriding erifyRenderingInServerForm on the page the control sits in. I tried to do this, but ran into other issues (for example the ajax control tool kit calendar extender started to complain about the extender not being registered properly).

I've got the ImageButton wrapped inside a form tag with runat="server" but STILL getting this error at runtime. The form tag is at the very beginning (before my table) and end tag is at the end (after the table).

<td>
<div>
<div id="pay-Button"><asp:ImageButton ID="PayButton" ImageUrl="<%=PayButtonImageUrl %>" OnClick="RedirectTest" runat="server" /></div>

AJAX :: 'TabContainer' Must Be Placed Inside A Form Tag With Runat=server

Jan 11, 2011

Since upgrading to VS2010, I've been having issuse up on issues with my apps. Some are pure asp.net web sites, other are webpats that are eventually be converted to a Sharepoint web part.

In one of these webparts, I'm building a tab control on the fly. It fetches data from the table via bll/dal. On my dev box I build this in the code file of the default.aspx file and rendering it in a panel, except that it get the said error. I'm quite sure this is how I've done it in VS2008, so I don't know what is going on here - see my code below.

Web Forms :: Is There A Way To Remove The Form Runat="server" From The Page

May 25, 2010

I'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:

Web Forms :: Significance / Material Difference That <form Runat="server"> Would Make In Scenario?

Oct 5, 2010

I am a bit confused about the significance of the <form runat="server"> on a page, and its effect on Page and Control life cycles.

For long, I have eliminated any Postbacks or Viewstate from my web forms. I just use web forms to render (often very very complex) UI to the client (composed of server-side controls as well as ExtJs or jQuery widgets etc).

After the UI renders, all interaction with server is asynchronous through web-services or http handlers. So, lately I have started omitting the <form runat="server"> tage also from my web forms.

And to my surprise, the code has NOT broken. The life-cycle events are generated normally on all controls, they have access to normal ASP.NET processing pipeline, and they render perfect;y. As there are no Postbacks, I do not need ViewState or control events
like click etc.

So, can somebody tell me if there's any material difference that <form runat="server"> would make in my scenario, or to ASP.NET page/control life-cycle??

Custom Server Controls :: Create C# Controls On Server Side For Posted Data That Had No Runat=server

Feb 4, 2010

HOWTO create ASP.NET C# controls on server side for posted data that had no runat=server on the client.

I have processes needing to post files to a ASP.NET application. These processes must post without runat=server as such:

<form ~~~~ to some ASP.NET/C#/aspx page>
<input type=file name=MY_FILE ~~~>
</form>

On the ASP.NET page, in the Page_Load I would code somethign like this:

[URL]

Here is the trick, the control "fileLIST_FILE" does not exist because the HTML does not have runat=server on it.

If the client did have runat=server the designer.cs would have somethign liek this:

System.Web.UI.HtmlControls.HtmlInputFile fileLIST_FILE;

With all that said, I want to make "fileLIST_FILE" on the fly inside Page_Load fromt he posted name of "MY_FILE".

do not focus on the fact that this is a file upload. I would like to know how to do this for any posted FORM data.

C# - Using Server Variables In A Href <%= Xx %> With Runat=server?

Nov 29, 2010

When I use an anchor tag on an aspx page as below,

<a href="~/pages/page.aspx?id=<%= ServervariableName %>"> test </a>

it will get the variable value correctly assigned to id but it won't route the page correctly as the ~ will not be evaluated without the runat="server" attribute on the 'a' tag. But once I add the runat server attribute, it does not evaluate the servervariable name anymore.. how this works or what I should do to take care of both?

Set The Value SomeValueReturnedFromADatabase To A Control That Is Not Runat=server?

Jan 6, 2011

Its simple if I have an ASP.net page with an ASP.net linkbutton / hyperlink and I obtain a value from say a SQL Database and I store it in the label...

For example:

this.myLabel.Text = someValueReturnedFromADatabase

This is simple because it goes right to the code behind page and set the text value to the value returned from my database (aside from going into more details with data access layer, etc).

What I was wondering is what if I dont want to use an ASP.net linkbutton and I simply want to use an HTML link button (as I need to call the jquery fade function). How would I set the value someValueReturnedFromADatabase to a control that is not runat=server?

.Net Runat Server Controls Not Compiling?

Mar 29, 2011

I have created a new Web project (.Net 3.5) and I've removed the original Default page in favour of creating a Master page and then recreating a Default with Master page. All worked lovely. Now, when I add my controls inside of the ContentPlaceHolder on the Default page, I get compiler errors when I try to access the controls from the CodeFile:

Error 4 '_Default' does not contain a definition for 'FirstName' and no extension method 'FirstName' accepting a first argument of type '_Default' could be found (are you missing a using directive or an assembly reference?)

My declaration of the control:

<asp:TextBox runat="server" ID="FirstName" />

EDIT

Page declaration:

<%@ Page Title="" Language="C#" MasterPageFile="~/Master/MasterPage.Master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

why can't it see this property or the server method RedirectToPayPal? I get a runtime error of :
