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.)
After upgrading our project to the .net 4.0 framework (from 3.5), we facing some problems with ajax calls with html in the parameters. As soon as the user enters some html in a text area the ajax call isn't executed anymore. If the user enters plain text only, there is no problem.
I am trying to set the Backcolor of this TabPanel in code behind. But the color of the TabPanel is still white. I also tried the TabContainer with no success.
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 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?
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.
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:
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 gridview that shows when something is check out. I would like to only show results from todays date and forward. I have done this in Expression Web but when I tried to use the same code in Visual Studios it doesn't work.
I'm generating the rdlc at runtime and I'm using LoadReportDefinition(memorystream) to provide the definition to report viewer. It works fine but when I export it to pdf or excel, the file extension comes in as .xls[1] or .pdf[1].
I have tried giving the DisplayName property but it doesn't work.
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..
I 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. To make sure I wasn't doing something wrong, I downloaded the samplcode (vb) from the AJAX website, and created a completely new web page, css file, .vb file, etc. Still have the same issue. I am using the latest version of ajaxcontroltookit ( 4.1.40412.0), VS 2010 RC, and VB)
I have the book ASP.NET 3.5 WEB SITE. I can't get the view/edit employee to work. (Chapter 10) I have copied the code from the "download chapters" and it still doesn't work. Am I missing something? I don't see where there were typos on this chapter
