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.

In the original site, master page has code-behind to check a query string parameter value. Depending on this value, code-behind dynamically modify some CSS property to hide / display master page elements.
As MVC2 has no code-behind because we are supposed to perform everything in the controllers, how should I proceed in this case ?
I see this : [URL]
It partially answers my needs but the query string processing is common to all pages. How can I move this processing in a common code section ?

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)
{
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);
}
}
}
}
}
}
}

{
public void ProcessRequest(HttpContext context)
{
{
string PhotoPath = System.Web.HttpContext.Current.Request.QueryString["PhotoPath"];
PhotoPath = HttpUtility.UrlDecode(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";
context.Response.BinaryWrite(mStream.GetBuffer());
}

View 3 RepliesI 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

View 2 RepliesI have a page on my website with access granted to logged in users (I'm using the built in asp.net membership database). This works.
However, when passing a querystring parameter in combination with that url address, the user is denied access.
I would like to alter the query that is run, depending on the selection made by the user in a drop down list on the same page. Would this best be done using a partial page update (AJAX)? Ideally it would be great to have the textbox result change quickly once the drop-down list value has changed, without a full page postback. I would like to change the SQL query to a completely different query if the user selects an option different to the default (page_load value) in the drop-down list. I would then like the newly retrieved result to be displayed in the textbox as before.
My current VB function looks like this:

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

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?
