I have a input of type file and when i try to do a Request.files when the input is wrapped in an update panel...it always returns an empty httpfilecollection. Why???
This is the codebehind: (At HttpContext.Current.Request.Files...its always 0 for the count.)

i have my NEWS BAR script code in my home Page which inherits from masterpage like this :
<asp:Content ID="content1" runat="server" ContentPlaceHolderID="mainholder" >
I am trying to do some code where a user will be able to upload a .JPG picture from the users computer. I have put the controls and also written the C# code wich in my eyes seems to be correct. What happens in the code is that the uploaded picture will replace the existing "TopHeader.JPG" picture.
However when I run the code after I have choosen a .JPG picture from the desktop on my computer. Nothing happens except of a postback of the page.
I wonder what I can be missing out in order to make this work. (I attach both the HTML code and the C# code, I will be happy to know what I could be missing out)

I want to read from database where I've stored a image in binary field and display a image.
while (reader.Read())
{
byte[] imgarr = (byte[])reader["file"];
Stream s = new MemoryStream(imgarr);
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
Graphics g = Graphics.FromImage(image);
g.DrawImage(image, new Point(400, 10));
image.Save(Response.OutputStream, ImageFormat.Jpeg);
g.Dispose();
image.Dispose();
}
con.Close();
This piece of code doesn't work:
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
I tried the code from this article. And I got the same mistake " the parameter is not valid ". Maybe I'm not aware of something, some setting in sql server or webconfig or sth else. Anyone else who has experience from fetching images from database? The parameter is not valid is the error message. db table contains data. What am I doing wrong?
I had a website with a few asp.net controls with id like:
btnSave and tbAmount
I renamed one of my controls and when I tried to use it in the code behind I get the following error.
Error 5 Name 'tbAmount' is not declared.
I was messing around trying to add new controlls rather than rename, but nothing seems to work.
And now, none of my controlls that were added to the page are recognized in the code behind. They all have the error:
Error 5 Name 'tbAmount' is not declared.
Or
Error 3 Name 'hfNoteId' is either not declared or not in the current
scope. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 33 71 NoteTender
Even my button click event handler gives me the following error:
Error 2 Handles clause requires a WithEvents variable defined in the containing type or one of its base types. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 27 91 NoteTender
I have verified that my inherits is using the correct namespace and class name.
Due to requirements, I need to open a popup window (javascript window.open(url)) and the url value is an aspx page that downloads a file.
[Code]....
I've tried numerous variations of this code: writing to buffer, Response.WriteFile(), Response.End(), etc...
Nothing works.
All the page does is pop up for about a second and then disappears. I can step thru the code in debugger, but the file never gets downloaded.
I've seen several other posts about this in various places, but no definitive answer.
I am using IIS7 Windows 2008 server.
The project I'm working on allows an end-user to modify CSS code to integrate the application as best possible. Most of the CSS values are stored in a database and need to be retrieved and parsed dynamically. I setup a Style controller, and gave each stylesheet an action, and then passed the configuration data through to the View. I set the ContentType to "text/css" and then generated the stylesheets. This works fine, but the problem I'm running into is this: none of the code works in the application. I include it in the head code, but it doesn't parse in the code. An example of what I do is this:
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" ContentType="text/css" %>
.element {
background-color: <%= ViewData.Model.BackgroundColor %>;
}
I include it like so:
<link href="/style/Basic" rel="stylesheet" type="text/css" media="all" />
When I include the CSS code in a partial view and include it using the ViewModel (wrapped in style tags) in an action, then everything works fine. It is when I try to parse this as a separate file when it does not work. Is there something I am doing incorrectly? Or is there some kind of glitch?
I've been told by my host that I need to enable FullTrust in my webmatrix website because I keep getting an error. (BUT, I have used a different host, and everything on my site works perfectly with them without modification). Anyway, I used the code my host suppllies in their KB, but that just generates a different error. So I looked up full trust on google and used about 5 different code samples to enable full trust but they all generate errors! even the ones on MSDN. And googling "Full Trust WebMatrix" doesn't really bring anything helpful either.
How can I successfully add full trust to a web.config file that is made using WebMatrix?

I have a form in aASP User Control (.ascx) file. Maxlength does not work for the multiline textboxe hence it is generated as a textarea, which has no support for this attribute. I could maybe use some asp validation, to prevent submission of too much text, but I want to prevent it to be possible to even enter too many characters, just like is possible for single line textboxes... I don't know if the control has any onload event that I could use to add attributes to the textbox from code behind and and combined with javascript fix this or anything..
View 1 RepliesI am trying to get the modalPopup to work. Don't get any errors, the panel popsup as is supposed to, but the background doesn't gray out and the background of the panel doesn't display correctly either (it is black). The background of the main page doesn't change.
