1. I compile the project,
2. after compilation i transfer the compiled files via ftp. then i delete the existing files on my folder and put the newer one.

I am able to upload a file to the server into a folder structure. but when I try to link to the file, the image path in the code is giving a strange url.
It should be something like
<a id="GridView1_ctl02_HyperLink1"
href="../MyFiles/1.jpg">HyperLink</a>
but instead its coming back as
<a id="GridView1_ctl02_HyperLink1"
href="../MyFiles/%3C%25#%20Eval(%22filename%22)%20%25%3E">HyperLink</a>
I am using this code to link to the button - which I'm sure is causing the problem
<asp:HyperLink
ID="HyperLink1"
NavigateUrl='~/MyFiles/<%# Eval("filename") %>'
runat="server">HyperLink</asp:HyperLink>

For our application we provide users with file downloads that utilize handlers to serve the files. Currently, the way it is served to the user is through window.location. When using this, at times, it causes issues under IE8. When an error occurs, it cannot be caught under the page that called it.
A) Is there a way to serve an ashx file handler to the user where the page that called it can catch any exceptions made from thje handler
B) What is the correct way to serve the handler, eg. window.open, window.location, etc. Would return false at the end of the javascript solve this? Are there any other ways

I am working on ASP.NET3.5 platform. I have used a file upload control and a asp button to upload a file. Whenever i try to upload a file which contain special characterlike (file#&%.txt) it show crash and give the messeage "Server Error in 'myapplication' Application." A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.
Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. how can i prevent this crash using javascript at client side?
