Feb 23, 2010
I have a detailsview with an upload image to the database. Image is save as binary file in database, and imagename is the name of the file.

Is there any method like OnInserting or something that allows me to retrieve the file name and save to database?
I have a FileUpload control that currently uploads pics to the Photos folder on my server. What I would like to know is how would I give it a randomly generated filename when it gets uploaded? As I don't want duplicates later on down the line. Cheers.(Code below).
Please help to understand this RegEx statement in details. It's supposed to validate filename from ASP.Net FileUpload control to allow only jpeg and gif files. It was designed by somebody else and I do not completely understand it. It works fine in Internet Explorer 7.0 but not in Firefox 3.6.
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?

But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.

How to get data (read file) chosen in FileUpload control without FileUpload.SaveAs Method on the server? Is it possible write it at once to some object?
I have a FileUpload control in an UpdatePanel and when user select a file, the full file path will will be stored in a hiddenfield, and during postback, i would like to assign the full file path in the hiddenfield back to the FileUpload control textbox, possible to achieve that?
I have an application where the user uploads files.
GOAL:
I need to check the file name for special characters and replace them with an underscore. Is there a Select Statement OR IF Statement I can use to search the fileName for unwanted special charaters; those characters will be replaced with a blank or underscore?
I want to replace ampersand, Number sign, Apostrophe, and so on.
in my code when i look at txtLocalResource.PostedFile.FileName it returns only the filename, the rest of the path is missing? i am using ie8 and vs2010.
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.
And I'd like to update it to the value of FileUpload1.PostedFile.FileName I have this in a variable in the aspx.vb page as myFileName How would I use that value in the UpdateParameters section?
