I've a page in ASP.NET, whose appearance can change based upon a given parameter(say query string),
How can I achieve this in ASP.NET, Master pages concept won't work here, as even the contents of the page and positioning of the controls on the page can change based upon the parameter.
One solution I can think of is using XSLT, but is there any other solution I can use to solve this problem? Is there any concept of templates I can use here?
Question basically crams it all in... I'm loading a page with a querystring (ID), and I need to use that ID to set the selected item of a ListView when the page loads. The ID is a DataKey on the ListView. I have no code of value to post--none of my attempts at this work.
View 2 RepliesSummary: I need to authorize pages based upon the data present in the query string of a url, not just the page name.
Background:
Let's say I'm building a library inventory system. Users can be created and assigned to a single library in either an Admin or User role. There are hundreds of competing libraries in the same database, so it's important to ensure that users of one library cannot view inventory from another library.
Right now I'm using a pretty standard ASP.NET setup: Forms Authentication using the SqlMembershipProvider. Authorization using the SqlRoleProvider, configured via <authorization> sections in the web.config. Security trimming with the SiteMap provider to hide unauthorized pages.
To control the inventory information from leaking, I'm manually checking a user's associate library ID with every inventory query. It works, but it's tedious and prone to errors. There has to be a better way.
Question:
Now users have the ability to create arbitrary "collections" within a library. (e.g. Collection A has Books 1, 2, & 3 in it.) Admins want the ability to grant Admin / User access on individual collections, not just the entire library.
So, if a user goes to www.com/Book.aspx?BookId=1, the system needs to ensure that user has permissions for the collection that "Book 1" is in before showing the page. If they go to www.com/Reviews.aspx?ReviewId=23, I need to make sure the Review is for a book that is in a collection that they have permission to view.
1) How can I implement this in the most standard ASP.NET way possible?
Manual checking within a base page?
A custom HttpModule?
A custom Role Provider?
I'm not interested in how to store the admin/user permissions, but rather how/where to authorize based on those permissions.
(examples on how to implement any of those are appreciated)
2) To further complicate it, I'd still like security trimming to check if the user has Admin rights on any collection or library and hide the admin pages if he doesn't.
I have a page that is used to add info from a gridview into a user's profile. I have explained my issues after all of the code. Here is the applicable code(s) involved:
Protected Sub AddToCart(ByVal sender As Object, ByVal e As CommandEventArgs)
For Each gvr In GridViewItems.Rows
Dim txtGiftAmt As TextBox = (CType(gvr.FindControl("txtGiftAmt"), TextBox))
If txtGiftAmt.Visible = True Then
Dim customPrice As String = txtGiftAmt.Text.ToString
'HERE is where I would like to set the new price variable value somehow
End If
Next
Dim scart As New ShoppingCart
scart.AddCartItem(e.CommandArgument.ToString())
Response.Redirect("~/ShoppingCart.aspx")
End Sub
This sub is called by the following button when clicked:
[Code]....
Here is the sub from the ShoppongCart Class named AddCartItem:
[Code]....
Here is the problem that I am having: I have one specific item that allows user's to define their own price (for this item only). By putting this price in a session variable seems to be the easiest way to handle this (at least for me), but the session variable's value always "lags behind". By this I mean that the first time the items is entered, it uses the default value of cartItem.ItemPrice. The second time the same item is added (with the intention of a different price), this new item's cartItem.ItemPrice is set
as the first session("customPrice").
Because the user is selecting his/her own price for this item, I am not worried about lack of security involved with using query string to pass this price, but I can't get the string passed to the ShoppingCart class correctly (shows up null). Is there a way to append this customPrice to the current page's query string before the Response.Redirect takes place? If I understand this correctly, the Response portion "posts back" to the current page before the Redirect sends us on our merry way, right?
i created a web application which has a media player in between,but when i open the application on my ipad or ipod, the video doesnt play as the video player doesnt support ipod and ipad,,
i found out a way with which i can play it but how can i redirect the page based on the client side.
i would like to know a C# code to know what kind of browser the user is using.
This will be typical question to ask, but i havent found any right soultion to this. I need to redirect pages based on devices browsing, mostly focusing on iPad, iPhone, Blackberry. But i need server side code, for this; as javascript is disabled by default on Blackberries, so tring to avoid javascript. I have checked MVP Mobile Devices, but dont know how to implement in my sites.

I'm not sure if this is possible or not, I'm using Roles to limit what pages a user can access based on there assigned Role. My question, is there anyway to redirect the user to a specific web page based on thier role after they login.

I have page A, B and C. In the page load of C, i have used a query string parameter to display some tables depending on where it came from, either A or B. Page C has Cancel button.

I am trying to retrive the query string value and display it on the aspx page. The query string is passed from a gridview. Everything works fine except i noticed that when there is an '&' in the query string then the label on the page will display only uptil the '&' (i.e. excluding the '&'). Just so to let you know. I retrive the value of the querystring into a string variable and then assign it to the variable. I have noticed this only for '&' character but maybe there are more characters with sinmilar bahaviour that I am not aware of.if anyone has a workaround on displaying all the content from the querystring then do share.

I have a problem that the OnLoad event is not fireing when I navigate to a page and just change the query string. If I do a postback it is called, then changing the query string ones more OnLoad gets called.
Here is how i try. I navigate to the page OnLoad fires -> then change the query string page updates (all bound elements get updated) OnLoad does not fire -> I do a postback using a button OnLoad fires -> then change the query string OnLoad fires. I will try to explain in more detail.
The system has log in window when I log in I navigate to an other aspx page sending two query string messages the last query string is a number (page.aspx?key=text82&key2=2010). When I get to the page the first time PageLoad event gets called and all is fine, if I in the browser change the key2 to 2011 and press enter the PageLoad does not get called but all my bound elements get updated (GrivView etc..). If I then do a postback using a button the PageLoad gets called. If I now change the 2011 back to 2010 and press Enter PageLoad is called. I try this is firefox the PageLoad get called every time. I tired to write a test website but I do not get the same problem, but what i found out is that in IE 8 changing the query string to the same number and pressing enter the PageLoad is not called. But doing so in firefox makes the postback fire. Here is the test code
