Page Not Found (404) On Postback From Default Page In A Subdirectory?
Feb 23, 2010
A website's default page is setup as follows:http://mysite.com/myapp/ ==> http://mysite.com/myapp/views/default.aspxAs you can see the only thing a little out of the ordinary is that the default page is in a subdirectory (views)If I access the page via the default URL (http://mysite.com/myapp/) the form tag looks like this<form name="aspnetForm" method="post" action="default.aspx" id="aspnetForm">The problem is that the page posts back to http://mysite.com/myapp/default.aspx (missing the "/views/" part of the path) which is a non-existent page, so I get a Page Not Found (404) error.
I have a GridView that (in one particular instance) would contain about 5000 rows, each row containing a DropDownList with about 5000 items. Naturally, this takes forever to load and throws and OutOfMemory exception on my box.
No big deal, I thought. I'll just enable paging. Well, that works fine (for the same gridview) when its bound to other data, but when I bind it to this particular DataSource (the one with 5000 rows) problems arise.
When I first load the GridView with the offending DataSet, page one displays just fine. However, when I click to view page two I get the error:
Error 101 (net::ERR_CONNECTION_RESET): Unknown error. In Google Chrome. And the error: Internet Explorer cannot display the webpage In IE.
I'm creating user controls that i will put into an update panel and make them visible only when required using triggers. Once visible it will float in a dialog box so it has a close button which will just hide the control on client side.
The controls have multiple post back states, like a wizard, i'm using a multi view control to accomplish that. My problem is that once the user is at step number two in the control, if the user closes the dialog, than opens the dialog again, (note that the control is made visible on the server and reloaded by updating the updatepanel) the second step will still be displayed. The reason is . because whenever there is a postback the control will load its state using the viewstate, even if EnableViewState is false it will still load it using the LoadControlState method. so my quesion is how can i force a user control to load fresh with its default values without any postback data.
I have a web application. In my application,I have a normal sub directory named "sub" . In sub, I have a a webform 'mywebform' and its .cs and designer file.Now , when I deploy by web application by copying all aspx file and bin folder through ftp, all my aspx pages work fine, but mywebform.aspx creates a problem . It throws an error:

I've upgraded my web application from ASP.NET 2.0 framework to 3.5. I've also updated AJAX toolkit from 2.0 to 3.5. The updated was made on 20th of January.
However today the application started giving me error that there is no ScriptManager on the page although it's (I'm using AJAX ModalPopupExtender on 2 pages). I didn't change anything on the pages except yesterday I've added one ASCX control to both pages but problem doesn't disappear even if I remove the control.
Basically the thing stopped working for no particular reason. I will try to reinstall the AJAX toolkit and I think that there are maybe somethings to change in web config but it's strange since it worked perfectly until few hours ago.
I need to force SSL when going to the final checkout page (for example from default.aspx to checkout.aspx).
I need to pass variables to this check out page and tried to use server.transfer(https://www.mydomain.com/checkout.aspx). I then use previous page .Fincontrol to read text box and label name to this check out page. If I only do the server.transfer("~/checkout.aspx") then my I can read all vakues of my controls from the passing default.aspx page.
But when I force https:// then I cannot read the control values from default.aspx page.
Please give me some tips on how to get control values to the https:// destination page or if you have another tips on how to do it the right way, please let me know.
I have a Asp.Net application eg its name is ABC and I have a server eg whose name is XYZ, where the application is hosted from. The default page for the application is Home.aspx.Now the requirement is I want Home.aspx to open automatically when the server name is typed in the URL. Currently for accessing the Home page I writehttp://XYX/ABC/Home.aspx but I want Home.aspx to open if I writettp://XYZCan anyone suggest how I can achieve this. I have one solution that is making a HTML page as default in IIS and then redirecting it to the respective link.
I have a master page that has a text box at the top with a couple of words in it. Below that I have a horizontal menu and below that there is the content place holder.I wish to set a default background color on the master page so that each other web page that uses this master page will inherit this background color.How do you do set a background color on the master page?I can't seem to select the background to set a default background color because the controls I have placed already.
I have created an order checkout page.when i click checkout button then it check user login or not if not then it redirect to login page .after login i want to show
I have a small part of my page existing on the master page. this small portion is embeded within an update panel that I postback using asynchronus postback. The problem is that; my default.aspx page which uses the master page gets affected (i.e I lost the text in the textboxes) on the asynchronus postback although the update panel doesn't include these textboxes. Is there a solution to ensure that postback only affects this part of the page?
obj = new common(); con = new SqlConnection(); con = obj.getconnection(); SqlCommand cmd = new SqlCommand(); SqlDataReader rd; cmd.Connection = con; con.Open();
cmd.CommandText = "select username,password from user where username =@username and password=@password";
[CODE]..
when username and password is correct , it should redirect to default page.
Suppose I have a server wid some virtual name as ABC. And also I have a .Net web application XYZ with some .aspx pages like Home.aspx etc. Now if I want to make Home.aspx page as the default page when I type the server name in brower the Home.aspx opens automatically.
Currently Iam accessing the application with this URL https://ABC/XYZ/Home.aspx But I want to access the application in this way: http://ABC
I am trying to create a website containing an application written in Silverlight. Because of SEO, I want to have this Silverlight application on one page of the site, whereas the other pages are ASP.NET MVC, explaining about the application, general info, etc.
I was able to find an example on how to add a silverlight application to an ASP.NET MVC view. Basically, I just have to add:[Code]....
to the <asp:Content> block.
However, this only seems to work if this snippet is added to the default page (/Home/Index in case of an out-of-the box ASP.NET MVC application). If I add the same snippet to, for example, the About.aspx page, nothing shows up. If I make the About page the default page by changing the route to: [Code]....
then the Silverlight application is launched on the About page (now the default page), but no longer on the Home page.So my question is, how can I get my Silverlight application to launch on any page in my ASP.NET MVC aplication, not just the default page?
I am tring to send form values to a page from a user control. I included the user control in a master page.When i use page.previouspage it can not get value. is there any way to send form data to a page from a user control included in a master page?
It renders Fine with Register symbol after the text "My Test Application Name" on start of the page but on any postback the title turn into My Test Application NameŽ Kindly let me know what can i do with minimal effort to fix this issue
I have a FileUpload control in the Source page. On the Upload button handler, I read the file into memory (after doing some validations) and since it's always going to be a TXT file, I create a string that I need to pass to the Destination page. I thought of using Cross Page postback and set the PostBackUrl property of the upload button. But it appears that the breakpoint in the Upload button handler is never hit. It directly goes to the Page_Load in the Destination page. If I can't use Cross Page postback and don't want to use Session or the database, how do I pass this string from Source page to the Destination page?
When user cliick on the control before page fully loaded it goes to error page.
Following is the trace.
Execution Error
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Im implementing a simple form with ajax to warn the user if email has been used or not for registration, and it looks to be working fine with IE but mozilla does a full page postback and refreshes the whole page.
I already tried changing to updatemode to conditional, all the triggers are set as async, etc but mozilla keeps doing the same, Im sure it is a known problem I may not be the first one facing this problem so i guess there is a simple workaround for this.
When an asynchronous postback happened inside update panel, another postback happens also for MasterPagenot only update panel embedded page .I want to prevent this MasterPage postback . is this possible ?think like i have a MasterPage and another page which is test.aspx which is content page of MasterPagei have update panel at test.aspxwhen asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
