I have a set of code (noted below) in ProcessRequest(HttpContext context) in a generic handler .ashx file.
HtmlGenericControl holder = new HtmlGenericControl("div");
//Set holder's properties and customization
HtmlGenericControl button1 = new HtmlGenericControl("input");[code]....
Now as I am in a HttpHander, I want to get the HTML of holder control and write it through context.Respose.Write().
I'm dynamically creating a number of check box controls (CheckBoxList won't format as I need) by allocating HtmlGenericControl objects and adding them to table cells. A portion of my code is shown here:
[Code]....
The result is just as I want and, looking at the HTML, everything seems correct. However, when I try to read back the checkbox values on postback, Request.Form[id] always returns null. Part of this code looks like this:
[Code]....
I'm building a web app that assembles output on the fly, and I'm trying to find the right way to instantiate HtmlGenericControl to create a DIV tag. By default, instantiating creates a SPAN tag. Anyone know how to use it so it creates a DIV?
View 2 Repliesi am working on a dynamic tree menu with nested <ul><li>-Lists.
when building the nested list every <li> element should contain a <div> with a small icon and a css-style behind.
here is my code:
[Code]....
this way the result in the browser shows the name of every "aNavItem" but there are no icons. if i put the line to set the inner text of the div BEFORE adding the "imgMove" to it both things are shown - the name of the element and on the right the icon
the problem is that i want the icon to be on the left and then the text, but there is no icon at all with the code above (it looks like the setting of the inner text overwrites the already added image-control in the div-tag)
I have created an Asp.Net Ajax Server Control that will be dropped on several aspx pages. I have created an HTMLGenericControl within the OnInit method of the control. This control is a div. Within the code I also need to add an onclick event to a button so that this div is shown.
However, when I call divName.ClientID within the control to pass it to the javascript it doesn't include the part of the ID before the "divName" section of the rendered control id - ct01_ct01_divName.Here is part of the OnInit() method within the ASP.Net Ajax Server Control.[Code]....
I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?
I'm sure I'm doing something wrong here, but I cannot figure it out.

I would like to referecne "div" that I dynamically created in code behind.

I get error saying can't find the div.
How do I reference div that I created in code behind?
runat="server" seem not working.
Something I have always wondered...Is there any difference in overhead between using Panel or HtmlContainerControl when needing to create a serverside container in ASP.NET.
HtmlContainerControl Container = new HtmlGenericControl("div");
Or
Panel Container = new Panel();
Also, is there differences in what is rendered in different browsers? I've noticed that Panel seems to render as a div in all browsers I have seen.
In an ASP.NET application, I need to do some changes on every CSS file sent.So I created an HttpHandler (inside the app itself), added:
<add verb="*" path="*.css" type="MyWebsite.CssTestHandler,MyWebsite"/>
to Web.config in system.web/httpHandlers and modified the handler like this:
public void ProcessRequest(HttpContext context)
{
context.Response.Clear();
text.Response.Write("Hello World");
context.Response.End();
}
i know how to implement this thing..

View 2 RepliesI have created a HttpHandler to be used with SWFUpload to upload images to the server. This upload is done in an administration backend so users need to be authenticated to upload images.Initially I made the whole administration area deny annonymous users but because of the way SWFUpload appears to work it wouldn't work correctly with Forms authentication and would return a 302 status code.I had thought it would be possible to make the location of my handler public in Web.config and use context.User.Identity.IsAuthenticated in my handler to determine if the user is logged in.

View 2 RepliesSo I am working on a project in ASP.NET MVC 2 with C#.I have a View with a file upload but this is a flash component (.swf).The result of the file upload (the storing of the file and processing of data in the database) is done in a HTTPHandler.I would like the HTTPHandler to send information to my active controller.
Is there a way to get the controller that was used to load the view? I'm having problems finding information about it online.

View 1 RepliesI am trying to pass an exception to an HttpHandler by doing the following:
catch (Exception e)
{
byte[] exceptionData;
MemoryStream stream = new MemoryStream();
BinaryFormatter formatter = new BinaryFormatter(null, new StreamingContext(StreamingContextStates.Persistence));
formatter.Serialize(stream, e);
exceptionData = stream.ToArray();
WebClient client = new WebClient();
Uri handler = new Uri(ApplicationUri, "TransferException.axd");
#if DEBUG
ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(BypassAllCertificateStuff);
#endif
try
{
client.UploadData(handler, exceptionData);
}
catch (WebException) { }
}
EDIT
I am getting the following exception on the client.UploadData() line.
"Content-Length or Chunked Encoding cannot be set for an operation that does not write data."
EDIT
Even if I change my call to be client.UploadString(location, "THIS IS A TEST!"); it still fails with the same exception.

I'm trying to fashion a solution which will simulate App_Offline.htm for remote access but still allow local users to test the website out. I found some various options that I am trying out but the best one doesn't seem to work for our ASP.NET(2.0) site which relies on session state being enabled on all of the pages.
The HttpHandler is added into web.config
<add verb="*" path="*.aspx" type="AppOffline.AppOfflineHandler, AppOffline" />
and when the class is called, it boils down to this:
public void ProcessRequest( HttpContext context )
{
this.context = context;

<asp:Image ID="imgVerify" Width="60" Height="18" runat="server" align="absmiddle" Style="border: 1px solid #999999" ImageUrl="/Common/GetCaptcha.aspx" />
It'll also trigger Page_Load() of abc.aspx. Is this that true? And if it is, can I avoid it?
