I would like to send along the page address that caused a 404 error in my custom 404.aspx file. Is this possible?
I'm using a redirect in the webconfig if a status code of 404 is encountered.
I have an ASP.NET web form application. In the web.config associated with this application, I handle my custom error like so:
<customErrors mode="Off" defaultRedirect="error.aspx" />
When a user gets to the error.aspx page, I want to determine what error caused this page to get reached.
Currently I have two events in my view that can trigger the post back (A dropdownlist and a submit button).
1. <%= Html.DropDownList("List", ViewData["Days"] as SelectList, "--Choose Day--", new { onchange = "this.form.submit();" })%>
2. <input type="submit" value="Submit"/>
When either of these are used, it they both call the [AcceptVerbs(HttpVerbs.Post)] Index() method.
What I want to know is how can I know which event caused the postback, because I need to process each one differently.
I have seen a million forums ask this question. This is what has been working for me.
protected void checkboxlist_SelectedIndexChanged(object sender, EventArgs e)
{
CheckBoxList list = (CheckBoxList)sender;
string[] control = Request.Form.Get("__EVENTTARGET").Split('$');
int idx = control.Length - 1;
string sel = list.Items[Int32.Parse(control[idx])].Value;
I'm way off and have just been lucking out, but I haven't seen a case where the index wasn't the last value in a '$' terminated string.
I have set up in javascript:
var onBeforeUnloadFired = false;
window.onbeforeunload = function (sender, args)
{
if(window.event){
if(!onBeforeUnloadFired) {
onBeforeUnloadFired = true;
window.event.returnValue = 'You will lose any unsaved changes!'; //IE
}
}
else {
return 'You will lose any unsaved changes!'; //FX
}
windows.setTimeout("ResetOnBeforeUnloadFired()", 1000);
}
function ResetOnBeforeUnloadFired() {
//Need this variable to prevent IE firing twice.
onBeforeUnloadFired = false;
}
I'm trying to achieve an edit screen where the user is warned before navigating away. It works fine except I get the pop up for normal post backs of button clicks. I'm hoping to avoid this so I'm figuring if I could determine which button was pressed it would work. Does anybody know how to determine which button was pressed in the indows.onbeforeunload? Alternatively anyone know a better approach to what I'm trying to achieve?

it need registry i think so, Now i did't get this error exactly
I am using VS 2008, IIS 7, .NET 3.5 on a vista machine. I created a new web-site using "HTTP", thus to use IIS. The application being created by VS 2008 created the virtual directory.
There are only two objects created initially with a new website "Default.aspx" and "web.config" file. I've made no changes and choose to view in browser and receive the following error:
It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
I've removed and reinstalled IIS 7. None of the sites previously created work. I've validated that a duplicate webconfig doesn't exist.
sender.GetType().Name returns me "default.aspx".How do I get the name or identify the control that caused the page postback (Page_Load() event)?
[Code]....
Is there a way to determine which control on a page caused a post back? I need to be able to make the determination since the _DataBound event of a FormView that I'm working with needs function differently based on which control caused the postback.
View 1 RepliesI have a calendar extender for a text box. I have set the text box 'causesvalidation' to false.
I have several other cntrols with required field validators. When I click the popup image for the calendar extender, rhese other required field validators show their error messages.
I have a Reportviewer control linked to Report1.rdlc with a matrix with Drillthrough activiated.When I click the "+" buttons to drill through, even I enclosed the control with Penal etc it still caused the whole page refreshed which is annoying. The same Panel code works well on other ASP.net controls on page on running.
View 1 RepliesList<ThemeObject> themeList = (from theme in database.Themes
join image in database.DBImages on theme.imageID equals image.imageID
into resultSet
from item in resultSet
select new ThemeObject { Name = theme.Name, ImageID = item.imageID}).ToList();
dgvGridView.DataSource = themeList;
dgvGridView.DataBind();
The list object populates fine. The datagrid is setup with 2 columns. A textbox column for the "Name" which is bound to "Name" An image column which is bound to the "ImageID" field. When I execute the code I receive the following error on the DataBind() Could not determine a MetaTable. A MetaTable could not be determined for the data source '' and one could not be inferred from the request URL. Make sure that the table is mapped to the dats source, or that the data source is configured with a valid context type and table name, or that the request is part of a registered DynamicDataRoute. I'm not using any dynamicdataroutes as far as I can tell. Has anyone experienced this error before?
can I retrieve the name that caused a postback? (VB.NET)

In Page_Load, Request["__EVENTTARGET"] is an empty string.IS there some way I can find out which button triggered the postback before hitting the buttons event handler
View 2 RepliesNot too sure if the title is the most appropriate description, but I've noticed at the bottom of my page I have a load of 'whitespace' / emptiness where my panel - that is linked to ModalPopup - is during coding / design. Is there a way of this space not appearing when the page is rendered? Setting the panel's visibility to false gives me all sorts of issues and I don't know where to go now to get rid of this annoying space!
View 2 RepliesI haven't actually dealt with multiple grids on one page in a very long time, so perhaps someone can jog my memory. I have two grids and a treeview in three separate jQuery UI tabs. Every time I page my gridview, which is a custom control inheriting from Gridview, the other tabs refresh.

I know practically nothing about AJAX, but fully intended to utilize it in the future. Right now though I am noticing a behavior that may require that I implement it sooner then I planned.
I have been working on a fairily sophesticated web form that is made up of tables, dropdown lists, map buttons, and labels. As various controls are selected, specific tables are enabled or dropdowns/labels populated with information. All of this is working great, but when I put it all on a server and accessed it from a remote location, I noticed that every single action caused the entire page to reload.
From what I have read, it looks like AJAX and the UpdatePanel control will allow me to only refresh those areas that should be refreshed. Before I look further into implementing this, is this the only way to go? From what I have read on some other blogs, the UpdatePanel has some high performance costs.
How do you determine if a button was clicked. If the high priority image button was clicked, it will send a "H" to the database, if not then nothing.
if(mybutton is clicked)
{ then send "H" to the database. }
I have a master page with a button that triggers a callback event. It works fine however, the content page's page_load event is raised when the button is clicked. The logic within the content page's page_load event is specific to the page and not to anything on the master page. How do I determine the sender of the callback event so that I can skip any logic to be performed in the content page's page_load event?
View 4 RepliesI am trying to set the color of a textbox that has focus to gray. How can I tell which textbox currently has the curser on it so when they click the change color button it will change the textbox that is focused. Something like this:

I have a page that im using javascript to do a select all / unselect all for my checkboxes on the page. Now i need to determine in the code behind if all of them are checked, im wondering if it would be easier to just set a session or something whenthe select all is checked, but that wouldnt be accurate, because after you select all, you still can uncheck some..
So i need it to check at the time the button is clicked.. there are currectly 30 checkboxes, NOT a checkboxlist.
I tried using the site search but getting an error has occured when i click to search..
if there is a way to determine if the default document has been served using .net? I thought perhaps something would be available in the server variables, but I can't seem to find anything that distinguishes between [URL] and [URL]
