I'm having an aspx page with 2 frames, one is the header and the the other one is content frame which i'm trying to load it dynamically. Everything is fine. Let me explain my scenario
On the header frame i'm having 5 link buttons and when a link button is clicked i'm passing a hardcoded Page URL to the frames containing page and then trying to load that page in the content frame.
Below is my code, Everything as far as i know are in right place, but i cannot see the page in content frame..
Header.aspx.cs
[Code]....
Then checking frameURL querystring in default.aspx page load:

when the querystring is null, the SiteSummary.aspx page is getting loaded in content frame without any issue, but when there is a querystring value the page is not being loaded.
Here is my Default.aspx page

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?
I am trying to get my head around the ASP timer control. What I am trying to achieve is to get a page to reload every 60 seconds but change the url querystring everytime between 3 values
i.e. scroll through
server/page.aspx?value=1
server/page.aspx?value=2
server/page.aspx?value=3
how I have though to do this is to use ASP code to grab the querystring value, and then create the next url. But I am having trouble passing that newly created url to a refresh control. im guessing HTML meta refresh is out of the question as I am using a variable. So from what I can see my option is to use the ASP timer control to count down (after the page has loaded) and after 60seconds load the next url.
i have a page with a piece of code. what the scenario is that that page can have more than two querystrings. for example it may have home.aspx?pck=1 or sumtimes it may have home.aspx?name=a
so i want to redirect to someother page based on the query string the page has.

this is what i have done now....bt couldnt work through it...its raising an exception saying "reference is not set".
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?
How do I create a query string from photopath on my database.aspx page to my handler.ashx page. I want the handler page to pick up on my photopath string contained here:
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{

{
string PhotoPath;
GridViewRow row = GridView1.Rows[GridView1.SelectedIndex];
PhotoPath = row.Cells[5].Text;
PhotoPath = HttpUtility.UrlEncode(PhotoPath);
HttpWebRequest request = (HttpWebRequest)
WebRequest.Create(PhotoPath);
HttpWebResponse response = (HttpWebResponse)
request.GetResponse();
Stream resStream = response.GetResponseStream();
using (System.Drawing.Image img = System.Drawing.Image.FromStream(resStream))
{
img.Save("temp.jpg", ImageFormat.Jpeg);
}
}
}
}
}
}
}
and then to retrieve it in my GetImage.ashx handler page here:
public class GetImage : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
{
string PhotoPath = System.Web.HttpContext.Current.Request.QueryString["PhotoPath"];
PhotoPath = HttpUtility.UrlDecode(PhotoPath);
FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(new Uri(PhotoPath));
request.Method = WebRequestMethods.Ftp.DownloadFile;
request.Credentials = new NetworkCredential("Administrator", "commando");
try
{
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Stream stream = response.GetResponseStream();
byte[] bytes = new byte[2048];
int i = 0;
MemoryStream mStream = new MemoryStream();
do
{
i = stream.Read(bytes, 0, bytes.Length);
mStream.Write(bytes, 0, i);
} while (i != 0);
context.Response.Clear();
context.Response.ClearHeaders();
context.Response.ClearContent();
context.Response.ContentType = "image/jpeg";

}

I have an ASP.NET website in which I have to perform a certain operation. I have to displaying the ID's from the DB on menu.aspx page in this format {1:2:3:4}. The above format is not a problem and can be just be written with
[Code]....
But here comes my question. I have to generate this ID when the user types the query within the URL somewhat like
[Code]....
Note that I am saying that user will type this URL. I know that query string can pass the values from one form to another but this is a single web form and if I attach this [Code].... , it should return the result. How can this be done?
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. When a user clicks Cancel, it has to check where it came from and should redirect to same page, i mean either A or B. I am not at all sure how to use query string for redirecting.

However, when passing a querystring parameter in combination with that url address, the user is denied access.
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
