PerformCallback On ASPxCallbackPanel Doesn't Seem To End?
Mar 17, 2011
We are using the ASP.NET controls from DevExpress.
In our application we use the ASPxCallbackPanel control at various places. the callback is triggered by "CallbackPanel.PerformCallback (...)" inside a handler of ClientSideEvents.ValueChanged .
Sometimes, and only when using Internet Explorer, the loading bar and the form gets locked. We do not get any server error - the client is just showing the loading bar, and doesn't stop.
The recommended error handling for callback errors is set in our Web.Config as follows:
<modules>
<remove name="ScriptModule"/>
<remove name="ASPxHttpHandlerModule"/>
[Code]....
Unfortunately, we can not really reproduce the error. It just occurs sometimes. Is there a way to set a timeout on a callback, so that the loading bar disappears after about 30 seconds? Or ist there a way to redirect to a special error page in the case of a hang?

I have a DevExpress grid that needs to be refreshed every time the value in a combobox is changed. For example, I have a combobox that sets the grid's page size. One of the requirements is that the combobox does not cause a full postback.
The combobox is declared like this:
<asp:DropDownList ID="cboPages" AutoPostBack="false" runat="server"
EnableViewState="false" OnSelectedIndexChanged="cboPages_SelectedIndexChanged" />
On selected index changed, it sets a cookie whose value is the selected value. When the combobox value changes, a javascript function is called:
function PerformCallbackOnGrid(grid) {
try {
grid.PerformCallback("refresh");[code]....
The function is attached in code behind: this.cboPages.Attributes["onChange"] = "PerformCallbackOnGrid(" + this.GridClientID + ")";
After performing these steps:The user changes the grid page size using the combobox, so PerformCallback is called at least once.
The user presses F5(refresh).
The user tries to change the page size again.
an 'Invalid viewstate' error message appears.
I have tried setting ViewStateMode to Disabled for the grid, also EnableViewState="false".

I am trying to save an updated xml file to a url like this:
Quote:
//save the output to a file
xmlDoc.Save("http://www.example.com/HomeNewsLinks.xml");
But I get this error: URI formats are not supported.
Did some google search on this and it seems I need to use client.uploadFile method, but I am not able to find how to declare/define filenamexxx (below) and how to pass a username/password.
Quote:
WebClient Client = new WebClient();
Client.UploadFile("http://www.example.com/HomeNewsLinks.xml", Post, filenamexxx);

I've gone over this code many times now but can't find why the modal pop up extender isn't displaying the details view in the modal pop up. This is a Master/Details that is using the modal pop up extender to show the details view.
When I step through the code, it is calling things in the right order. The pop up show method is being called. When I check the items collection of the details view they have the right headers, such as First Name:. I found the data for the customer object on the data bound event of the details view and it's the correct record. So the detail view is being passed the correct data and being bound correctly.
I created this from a working example. I followed the same pattern as the example. I can't find what the issue is in this one that is preventing the modal pop up from popping up.

Imports System.Data.OleDb
Intellisence does not come up and I am curious as to why Microsoft did not put it in there for intellisence use. My question is, well if Microsoft did not put it in there, How can I. I know putting the Imports statement in that it works, but Can I add the Imports statement to the guts of VS so I can use Intellisence.

1. The plus sign '+' is skipped (doesn't appear) when I submit the content.2. When I copy -for example- a code from Visual Studio and paste it in the editor, the spaces are skipped.I want the code to be displayed exactly as it is in Visual Studio.

I am following though the examples in Professional ASP.Net MVC 2 and one of the examples doesn't work for me.
[HttpPost]
public ActionResult Edit (int id, FormCollection collection)
{
Dinner dinner = dinnerRepository.GetDinner(id);
if (TryUpdateModel(dinner))
{
dinnerRepository.Save();
return RedirectToAction("Details", new { id = dinner.DinnerID });
}
return View(new DinnerFormViewModel(dinner));
}
I understand that it's suppose to take the values from the FormCollection, and then update the dinner object with it, bit I don't see the collection get referenced anywhere.

I am trying to embed a mov onto a cshtml page, all the resources seem to be referencing properly but the video won't play.
The videos are located in the /Content/Videos directory. I thought it was a permission issue but I granted everyone permission with no luck. Could this be an IIS issue? (Checked mime types for mov) or do I have put to do something in the global.asax (routes.IgnoreRoute) for mov files extensions?
Firebug shows when the player is clicked to play the video it does a successful get of the video but I don't think it is supposed to do a get action, I tested the same video from a plain html page opened from the file system, it doesn't invoke a get action when player is clicked.
I also tried to play the movie by typing the whole path in the address bar again no luck it just comes up with a quicktime logo with a question mark inside it.
Script references:
<script src="http://www.apple.com/library/quicktime/scripts/ac_quicktime.js" language="JavaScript"

<script src="http://www.apple.com/library/quicktime/scripts/qtp_library.js" language="JavaScript"

Script to embed the video:
<script type="text/javascript"><!--
QT_WritePoster_XHTML('Click to Play', '../Content/Videos/myMovie.jpg',
'../Content/Videos/myMovie.mov',
'520', '296', '',

I'm having a problem trying to work out if my button is working or not. I've tried twice, with the custom validator on and off. On both occasions, nothing seems to happen. Am I missing something with the validator and with the button?
I've been trying to debug it but can't work out how with just Notepad++ so I'm struggling for ideas on why nothing seems to work. When I press the button, it just goes back to contact.aspx.
contact.aspx
<% @ Page Language="C#" MasterPageFile="mastersmain.master" CodeBehind="app_codecontact.aspx.cs" Inherits="Contact.Email" %>
<asp:Content ID="Test" ContentPlaceHolderID="Body" Runat="Server">

I have an application in ASP.NET that uses forms authentication. It has the following code.
if (User.Identity.IsAuthenticated)
ViewStateUserKey = User.Identity.Name;
Stepping through I see this code executes on each page load. When a logged in user requests the page, the ViewStateUserKey is filled in with their username. If you let the page sit till forms auth times out, the user is no longer logged in, and a post back fails on validation of the viewstate because the name is now null. However I have noticed if I put other buttons on the screen, and the post back, it doesn't fail, even after authentication has timed out. Should this error every time it times out?

I am relativity new to asp.net programming, so this one has me stumped. I manually created a dataset and set its value to the Datasource of the GridView control and then call the Databind method, but it isn't refreshing. I recreated a simple version of what I am doing so someone can advise me what I am doing wrong. I didn't include the Master file, as I didn't see it as pertainent.
Code for ASP page

I'm just trying to teach myself a bit of CSS and it's pretty straight forward but I am getting something odd.
I built a css file, tried out various rules, all good.
Now I edit the css file. Everything compiles ok but it's still using the rules as they were before I edited them. I've even removed some of them from the css file and they're still being used. I tried removing the reference to the css file and the rules all stop being used (as I'd expect) but when I add the reference back in and the old rules reappear but not the new ones.
I'm guessing there's some 'built' version of the css file and that's what's actually being used. But rebuilding the website isn't causing the built css to refresh itself so my edits aren't being picked up.
edit> forget it, I was hitting f5 not ctrl f5. Just a bit of cuture shock switching from desktop dev.
