I'm using ASP.NET 4 Web forms routing, for example like this:
routes.MapPageRoute("page-browse", "{Language}/{Label}", "~/Default.aspx")
So the webadress could look like: http://localhost/mywebsite/eng/home
In the root of my website I have a folder "Images".
Image display works when I'm in the root of my website, e.g. by using http://localhost/mywebsite/default.aspx
But when using routing it doesn't work, because the image relative url will look at http://localhost/mywebsite/eng/images instead of http://localhost/mywebsite/images
Is there a way to prevent this using ASP.NET 4 Routing mechanism? Or is the only way to use absolute url's to images?
I've been trying to get image caching working for the last 8 hours and I keep the same problem time and time again, I'm trying to cache Images at the moment and then when thats succesful, apply this to cache my js and css files. I have at the moment Sql Dependancy caching working on my dynamic pages but the page still takes to long due to images not caching.
What I have tried is going to IIS7 Management and adding HTTP Response Header for the images folder and setting various things for the cache control.i dont care how long it caches it on the client or on the proxy servers i just would like it to check when the file was modified and compare it with the one in the client or proxy cache and if they are different then fetch the new image which has been ftp up. i could solve this by changing the image name but the thing is the image name is generated when they are ftp'd to the site by an application and the name is a direct reference to the product so i cant change the name each time, as it would mean making a lot of otherpages accross the board.
so What i would like, is to set and expiry date of lets say 32 days or more on the images and then check to see if they have changed by date modified or some other way of checking(Etags maybe) I'm not sure, if they have changed on the server then redownload and recache them, I tried using post-check and pre-check together but that just permantly cached them, so when i change the image the only way it would display the new image is to just hit F5.
In Brief, how can i Cache images, on the client machine/ proxy cache and recache them when the modified date of the file has changed.

View 8 RepliesI want to write one program by visual studio 2008 (C# and ASP) that has web application and windows application.
I want to get clients images in web app(upload) and store them in DB (mysql) then send these images to windows app via web service (so i new web service, not web site). But i have 2 problems:
I have 2 ways to store images in mysql, first i should have BLOB field in DB -that it takes more space-, second i should save just name of each image in DB(so have image in one folder) -in this way i don't know how get image from clients and store them in that folder-. which one? Or what other? How (code) can i transfer image via web service(Byte[] or? ).
I wanted to combine app_themes css files into one on the fly. I did so using Mads Cristensen technique. But now all elements that has background image defined through css (see picture) don't display image. I believe that is because css files are not relatively referenced anymore (../), but through axd file. I'm trying to fix this by changing reference to image files without success. I already tried background: url("~/App_Themes/44/images/myimage.gif") and this works for pages that combined css. But the problem is that there are other pages in this project that don't use this css combining and now they lost reference to background images.
View 1 RepliesViewState is active and I have a RadioButtonList with DataSourceID to LinqDataSource.If I postback and cause event SelectedIndexChanged, I can read the SelectedValue property, but if the postback is caused by another control, SelectedValue its always empty...Note if I turn ViewState off, works fine, SelectedValue has always a non empty string...
View 3 RepliesI am creating a wizard with a radiobuttonlist inside it. There are no style sheets being applied and I have the RepeatDirection set to Horizontal and the RepeatColumns set to 5. I have also tried changing the RepeatLayout from Table to Flow and nothing works. I want the radiobuttonlist to show up horizontally, but it keeps showing up virtically. Let me rephrase that. In the Design view in VS2010 it looks fine. However, when I view the live web page, the darn thing keeps going virtical.

I want to be able to display information about each rate pulled, mainly: a description for the user, the rate or charge amount, hidden from the user I would like to save the estimated date of arrival and shipping method code.
Right now i'm using a RadioButtonList to display the data, but with a name/value pair I can only do so much (unless I wanted to really hack it up and make the value of each list item comma delimited or something like that to be able to store all that data). There can be multiple rates shown depending on the number of shipping options rates are being pulled from. Is my only other option to use a repeater or are there any other clean options?
I have a radiobuttonlist and what im trying to do is throw an error label when the user fails to select the button from the list.

View 3 RepliesHow to Display the treeview control with multiple images(each link should be with one image) instead of + images in asp.net
View 2 RepliesThe radiobutton list I have display:
O Ford
O Chevy
O Other
[Submit]
If you click on the submit button [Submit] I would like it to pull the data from whatever information that was selected. i.e. if Ford was selected than Mustang, Focus and Explorer would be return. If Chevy was selected than Cobalt, Cadillac and Corvette would be turn and so forth. I guess I can have a stored procedure to be call when the [Submit] button is click which would be "select models from Types" but how will the proc know if Ford was selected Chevy or other. I guess the stored proc will have to accept the [Submit] as a string to know should it pull the Ford models or Chevy models. or is there a better way?

I have a RadioButtonList with three ListItems, like this:

TrueRuleCondition, FalseRuleCondition, and CustomRuleCondition are protected constants in the code-behind file that I want to use as the values for my listitems. Unfortunately, the values get treated as literal values instead of having the values of the variables inserted. Does anyone know of a way to do this or why this doesn't work as I expect it to?
I'm trying to populate my form that is made up of RadioButtonLists, a Text Box and a DropDown via Code Behind. WHen I run it, the Text Box and the DropDown populate, but the RadioButtonLists do not.

This solution doesn't work though. It doesn't leave the option of choosing anything from the list. Plus I would like it if it were a Radiobutton instead of a Dropdown. The field in the database is varchar(50).
I've two RadioButtonLists which pulls "fullName" and displays, the idea is for the user to select from RadioButtonList1 and RadioButtonList2 then submit the data.
If there is already values assigned from sql then there should be a selectedvalue for both controls. But I can't seem to get the controls to assign the selectedvalues.
I've a SqlDataSource, 2 RadioButtonLists and some code binding it:

Also when I go to select just one record from RadioButtonList and submit the data, it returns errors because it sees it as submitting null values.
