I know all about this exception, read the msdn article here [URL] but I do not know how to handle this when my boss does not want me to throw in false for the Response.End.
Here's what I have:
else
{
try
{
VoidlOrder(transactionID);
}
[Code]....
So,I have this code:
[Code]...
Even though I have buffer set to false,no text is displayed.I have tried adding a response.flush,with and without changing the buffer value.What exactly is wrong?I've also tried it with and without the label(i.e. with or without just Response.Write)
I have been googling/SO:ing this issue for a while and many seem to be sharing this, but I haven't found any successful solution to my problem.
Using MVC3 and Razor.
Master page contains:
<script src="@Url.Content("~/Scripts/jquery-1.5.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script>
AjaxTest.cshtml contains:
<div id="AjaxTestDiv">content</div>
@Ajax.ActionLink("Update", "AjaxTester", new AjaxOptions { UpdateTargetId = "AjaxTestDiv" })
AjaxTester action method:
public string AjaxTester()
{
if (Request.IsAjaxRequest())
{
return DateTime.Now.ToString();
}
else
{
return "FAIL";
}
}
I always get the "FAIL" returned, to a blank page, not in the targeted div.
Edit: Also note that if I remove the if (Request.IsAjaxRequest()), I still don't get back anything to the targeted div, but instead a blank page.
Edit2: Looking at the HTML generated, this is my link:
<a data-ajax="true" data-ajax-method="POST" data-ajax-mode="replace"
data-ajax-update="#AjaxTestDiv" href="/Area/AjaxTester">Update</a>
Have tried switching the method to GET, to no avail.
I am using Response.flush() method for download the csv file. I am create the html on page and call the Response.flush method. It is working good But when i am cancel the download and do the another operation , It genrates the error.
View 6 RepliesI have an webforms app that loses it's session variables on response.redirect. I've read Bertrand Le Roy's blog about this and still can't get it to work. The page works in production. However, when I try in the VS2k8 IDE, the session variables are there right before response.redirect and on the first line of the next page, the variables are nothing. I've confirmed the session id is the same so I'm not skipping sessions. The target page is relative so the web server doesn't think we're changing sites (as confirmed by the sessionid).
Response.Redirect("menu.aspx", False)
I'm using .net 3.5 and am currently creating a web application used to generate a report through Aspose.CellsActually, the page is composed in a form where I get the configuration of the report I have to generate. The "generation" button is in an update panel. When I click on it, the "generation" button is hidden and a progress bar appears. When the excel file is generated, I save it in a memory stream and I send it back to the aspx page where I change the headers to allow the file's download.
View 3 RepliesHi,
I need some explanations regarding the above exception.
I understood that if you place a response.redirect inside a try catch block, u will get the exception and the aspnet will handle the exception silently without the user knowing. But the thing is that right now i am having a hard time thinking of a reason
why the error will occur after some changes has been made and the codes with the response.redirect has not been touched.

I have a web app that makes a call to a webservice, and it is causing a ThreadAbortException. Why is this? This does not happen when calling the webservice in a windows form application.
View 1 RepliesWhat's the correct way of ignoring ThreadAbortException when logging exceptions?
Is it safe to just catch it in an empty catch block to make it disappear?
I m getting the error System.Threading.ThreadAbortException while exporting datatable to CSV. But export to CSV is completed sucessfully.Here is my Code:
Dim dt As DataTable
Dim sb As New StringBuilder
dt = objsqlds.Tables(0)

Referencing my Earlier Question, regarding downloading a file from a server and handling exceptions properly. I am positive that I had this solved, then in classic programming fashion, returned days later to frustratingly find it broken
Updated code:
private static void GoGetIt(HttpContext context)
{
var directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe = new FileInfo(......); [code]....
This was working fine, and returning the zip, otherwise if the file didn't exist returning 404. Then on the client side I could handle this:
public bool Download()
{
try
{
using (var client = new WebClient()) [code]....
But the problem now is two things.
1) I get System.Threading.ThreadAbortException: Thread was being aborted in the server side try-catch block. Usually this was just a file not found exception. I have no idea what or why that new exception is throwing?
2) Now that a different exception is throwing on the server side instead of the file not found, it would seem I can't use this set up for the application, because back on client side, any exception is assumed to be filenotfound.]
I am not able tto understand the differnce between REspose.Expire and Response.ExpiresAbsolute?
Is it mandatory to use both toghter?

Response.AddHeader is used to add a new HTML header,but what is an HTML header all about?and the parameters i am passing within it as the name and value;what are they?
I have a static method that I use to control REST styled HTTP codes when my mvc application encounters an exception.
The method looks like:
[Code]....
This is static becuase then I can call it within an action or inside a filter. The problem I am having is that when I call RaiseException inside a filter, it stills goes into the requested action. Response.End() doesn't seem to have any effect. Any clues on how I can get Response.End() to work when called?
I have an approve button.on clicking on this button it should show that an inactive value is present .Onclicking yes conformation it should save the data or else clicking on no conformation should return false; how i will do that?After alert it always submit the data.

This is the code i used.how i wiil stay back on Confirm 'no' click?
Is it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
View 5 RepliesI'm using Response.Filter in order to implement stream compression in accordance with HTTP Request Header Accept-Encoding
Here's the important stuff:
if (AcceptEncoding.Contains("deflate") || AcceptEncoding == "*")
{
HttpApp.Response.Filter = new DeflateStream(PreviousOutputStream, CompressionMode.Compress);
HttpApp.Response.AppendHeader("Content-Encoding", "deflate");
}
By and large this works as intended. However, I'm in a situation where I'm using an ActionResult on an MVC Controller to serve up files to the user agent:
Response.Clear();
Response.Headers["Content-Type"] = contentType;
Response.Headers["Content-Length"] = contentLength;
if (Request.QueryString["dl"] == "1")
{
Response.Headers["Content-Disposition"] = "attachment; filename=" + fileInfo.Name;
}
Response.Flush();
Response.TransmitFile(fileInfo.FullName);
To be more exact, the action method returns new EmptyResult() after the Response.TransmitFile() call. This works exactly as intended without the Response.Filter modification.
In this situation, the response entity reaches the user agent garbled and unintelligible. FireFox's Poster addon shows empty entities or jumbled entities coming back.
I have written simple HttpModule. context.Response.Output.Write is working fine. but not context.Response.Write().
View 2 RepliesI have following function which is called from a button click event
[Code]....
I am creating a zip file on the fly and wanted to download this file.Problem is that in Internet explorer when I click the button the download accelrator comes with file name as my page saying resume opendialogueif i click open then DAP window close and normal windows download manager comes but the event of my button fires multiple time?I don't know what to do with it
When to use Response.Flush? Do I need to call it every time before I call Response.End?
View 2 Replieswhat is difference between Response.write and Response.output.write
View 2 RepliesI've just finished reading URL vs. URI vs. URN, in More Concise Terms, and it's really helped understand the distinction between the three terms. Since then I've skimmed the RFC2141 and RFC2616 specs and Microsoft's Response.Redirect Method documentation in an effort to answer the following question confidently.
Given this line of code:
Response.Redirect("~/Foo.aspx");
And this resulting HTTP response (trimmed for context):
Status=Found - 302 Date=Wed, 24 Nov
2010 17:27:58 GMT
Server=Microsoft-IIS/6.0
X-Powered-By=ASP.NET
X-AspNet-Version=2.0.50727
Location=/MyWebApp/Foo.aspx
What name(s) most properly describes what has been placed into the "Location" header?
URL? URI? URN? URC? Which is it?
public CheckBox[] cb = null;
int z=0;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
cb = new CheckBox[count - k];
//Database code.........
while (dr.Read())//read data from access database
{
cb[z] = new CheckBox();
cb[z].Text = dr["Member_Name"].ToString();
Panel2.Controls.Add(cb[z]);
Panel2.Controls.Add(new LiteralControl("</br>"));
z = z + 1;
}
}
}
protected void Button6_Click(object sender, EventArgs e)
{
for (int x = 0; x < cb.Length; x++)//ERROR IS HERE:Object reference not set to an instance of an object.
{
if (cb[x].Checked == true)//EVERY TIME I GOT FALSE VALUE
{
//processing check boxes
}
}
}
Basically, when the page loads i set the div visibility to false. When i click the button, i want the code behind function to be called, and the div tag to be visible, true.
$('#Button2').click(function () {
$('#edit').show(function () {
});
});
<input type="submit" id="Button2" runat="server" value="Search" OnServerClick="Button1_Click" />
but when clicking the button, the page posts back, causing the div tag to be invisible all times.
I can set the return false to the onlclick event of the button , but i need to call the function also.
tell me the use of Validaterequest False?
