Generating Output Through Query String In The Same Page
Jan 17, 2011
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 a dynamic gridview which can be used to add new rows of two columns to specify a start date and an end date. I am trying to use a string collection to pass in the output from the textboxes to a parameterized query as shows. I am getting an incorrect syntax near 9 error. How can I make this work? I need to use the stringbuilder.
protected void btnSaveIterations_Click(object sender, EventArgs e)
{
int rowIndex = 0;
StringCollection sc = new StringCollection();
if (ViewState["CurrentTable"] != null)
{
DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];
if (dtCurrentTable.Rows.Count > 0)
{
for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
{
//extract the TextBox values
TextBox box1 = (TextBox)Gridview1.Rows[rowIndex].Cells[1].FindControl("start_iteration");
TextBox box2 = (TextBox)Gridview1.Rows[rowIndex].Cells[2].FindControl("end_iteration");
start_date = box1.Text;
end_date = box2.Text;...............

I have some code that is used to replace certain page output with other text. The way I accomplish this is by setting the Response.Filter to a Stream, Flushing the Response, and then reading that Stream back into a string. From there I can manipulate the string and output the resulting code. You can see the basic code for this over at [URL] However, I noticed that Page Caching no longer works after the first Response.Flush call.
I put together a simple ASP.NET WebApp as an example. I have a Default.aspx with an @OutputCache set for 30 seconds. All this does is output DateTime.Now.ToLongTimeString(). I override Render. If I do a Response.Flush (even after the base.Render) the page does not get cached. This is regardless of any programmatic cacheability that I set. So it seems that Response.Flush completely undermines any page caching in use. Why is this?
extra credit: is there a way to accomplish what I want (render output to a string) that will not result in Page Cache getting bypassed?
ASPX Page:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TestCacheVsFlush._Default" %>
<%@ OutputCache Duration="30" VaryByParam="none" %>
<%= DateTime.Now.ToLongTimeString() %>
Code-behind (Page is Cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
}
Code-behind (Page is not cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
Response.Flush();
}
Code-behind (Page still is not cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
Response.Cache.SetCacheability(HttpCacheability.Server);
Response.Cache.SetExpires(DateTime.Now.AddSeconds(30));
Response.Flush();
}

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);
}
}
}
}
}
}
}
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";
context.Response.BinaryWrite(mStream.GetBuffer());
}
catch (WebException wex)
{
//throw new Exception("Unable to locate or access your file.\nPlease try a different file.");

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.

I 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 am trying to add some filters to a gridview that I am working on, and I'm wondering if it is possible to generate links or buttons above the gridview based on the years returned in the dataset. For example, if my dataset contains dates from 2001, 2009, and 2031 in my date column, I would like to be able to take that data from my SQL query (getting a distinct list of years is not an issue), and generate the buttons. From there, I would filter the data in the gridview based on the user clicking the buttons.
Is dynamic generation of buttons possible in ASP.NET? I do have some other ideas of how to accomplish the same functionality, but I would prefer to do it this way.

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
<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeFile="Default.aspx.cs" Inherits="_Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
