I am currently trying to develop an application based on the NerdDinner sample and integrating some other stuff.
This is a very basic thing but i just cant seem to get it working.
In the site.master page, i have included the following script and other standard script files.
[Code]....
I have some javascript files for each browser version and for different browsers. I want to include this files in script tag of script manager. Is it will detect these files and load based on browser version? Is there is best way to handle this scenario declaratively in markup insted of codebehind?If not declaratively how in code behind?
View 2 RepliesMy colleagues have create a website and there is a webpage which contains a Tab.
He Implement the tab with the following method:
1.Load all content of the page
2.Use javascript to display those group content as block and organize them into tabs.
3.when user click one tab, then acitve it, and hide all other tabs.
And these functions works very well, but the performance is bad:
1.Load all contents cost lots of time
2.It will show all content at first, and then shrink to a tab control. When the user see this, it might think this is a bug of our system.
iam into problem of reading the value of the control which i alterd using javascript the sequence goes like this i got the text box control by using its id ,cleared the value of the text box,make the control disabled.when i tried to retrive the value of the textbox in aspx.cs.iam still getting the old value of the text box which i actualy cleared in the javascript
View 2 RepliesI recently ran yslow on a page i have (master paged etc) and it returned that there were far too many javascript files included (most of which I haven't added).
I guess my question is that given i have v1.0.20229.0 of the toolkit.dll (over .net 2)
I'm wondering if subsequent releases have fixes for this sort of thing?
I already know this solution. (transfer the slow loading page to a loading-interim-page which shows the animation and then redirects to the actual page)But I would really like to solve this without a redirecting page.
View 2 RepliesI have been experiencing some issues loading some web pages from my development machine. They were painfully slow. I disregarded this until I tried running my own site and found that the culprit was the show.ad.js file provided by google adsense.
Using firebug I see that the page hangs on the loading of this file and then aborts after about 5-10seconds. If I am calling multiple database records to a page it will load one, hang, abort and then load another.
Trouble shooting I have done and things I can rule out are:
My router or any other external peripheral. If I go to any other PC in the house the page loads fine and very quickly. I have tried cabled and wireless. The problem appears to be something unique with my machine.
It is not just my website, it is all websites with google adsense. I have turned off my firewall and shutdown anti virus. No change. It is from all browsers on this PC. I have tried chrome, safari, firefox and ie. No change. I do not have any ad blocker software installed that I know about.
I know there could be a million reasons why I could be having this problem but I thought someone out there may have had a similar experience. Failing that, is there any way I can trace the problem as I have no idea where to start.
Here is my Javascript
<%-- script to load the default image--%>
<script type="text/javascript"><!--
window.addEventListener('load', function () {
// Get the canvas element.
[Code]....
If you look at the img.src at the very bottom, it loads the defaultImage.ClientId from the server which is suppose to get the image on the page. If I use a normal url it works, but if I use document.getElementById(imgid).src it just doesnt load an image. I am assuming its because the javascript loads before the serverside code is ran. How can I get around this?
I have an asp.net page that has menu which loads user control dynamically when the menu item is clicked.Now in the user control i have some buttons calling javascript on clientClick.When i click this button,it throws javascript error
Microsoft JScript runtime error: '(function name)' is undefined
Here is the code snippet:
function CheckUpload() {
var flag = validatePage();
var Checktext = $("#HyperLinkUploadFile").val();
if (Checktext != '' && flag)
flag = true;
return flag;
}
<asp:LinkButton ID="btnNotifyOA" runat="server" Text="Recommend Award and Notify OA & AO"
ValidationGroup="Notify" OnClick="btnNotifyOA_Click" OnClientClick="return CheckUpload();" />
The above linkbutton and javascript is inside a usercontrol.
I have an image control that puts user's photo in it. Once it's loaded, I resize it using the javascript.But the thing is, when the page is loading, the image gets really big, then shrinks down being called by the javascript. Is there a way for me to pre-load the image before displaying it? I do'nt want to set the image control's width and height to fixed pixels at this point.
View 8 RepliesI have seen few website where their home page is too big and when user scroll down to read the content the of the page then few area of that page load dynamically. how they design their page. as example the site is http://blog.rainbird.me/ where you can see the effect. please give me idea to achieve it via jquery & ajax.
View 3 RepliesSo imagine a piece of Javascript as the first script on a page along the lines of
var MySuperObject = new (function () {
this.SuperObjectInit();
})();
Now imagine that everything that proceeds this script (or a large portion therein) requires the SuperObject to have met its load conditions and loaded correctly.
Assuming for whatever reason the loading of the object fails I need to abort loading the rest of the page and the scripts in particular.
I know the majority of you are going to scream why not have your function issue a callback onSuccess and onFailed but the problem is this is in a ASP.Net project with masterpages, nestedmasterpages, usercontrols and so forth (each of which have their own dependencies and scripts); rendering such an approach problematic.
The other option (I assume) is to use window.location = "myErrorPage.html"; but I dont like the idea of having to create another page for an error message or the fact that it causes a redirect.
What I am hoping to do is something along the lines of
StopLoadingPage();
document.write("Error has occurred");
I have a website with a menu, when menu item is clicked I display the page for that menu in an iframe(iframe is set to display home page initially by default). sometimes it could take few seconds to display the page for the selected menu item (for example reports) and I would like to display a loading image while the page is loading. how to do this using javascript or jQuery

I have an UpdatePanel with a repeater in it that is re-bound after a user adds an item to it via a modal popup. When they click the button to add a new row to the repeater the code-behind looks something like this:
protected void lbtnAddOption_Click(object sender, EventArgs e)
{
SelectedOption = new Option()
{
Account = txtAddOptionAccountNumber.Text,
Margin = chkAddOptionMargin.Checked,
Symbol = txtAddOptionSymbol.Text,
Usymbol = txtAddOptionUsymbol.Text,
};
Presenter.OnAddOption(); // Insert the new item
RefreshOptions(); // Pull down and re-bind all the items
mpeAddOptionDialog.Hide(); // Hide the modal
// ... Make call to jQuery scrollTo() method here?
}
This works fine and the new row will show up quickly via the UpdatePanel. However, there are often hundreds of rows and where the new one is added is based on the current sorting column used. So, I wanted to take this as a chance to use the sweet jQuery ScrollTo plugin. I know that if I give it the ID of my overflowed container div and the ID of an element within it, it will smoothly scroll straight to the users newly added row. However, there are two problems:
I need to find the appropriate row so I can snag the ClientID for it. I need to execute the jQuery snippet from my code-behind that will cause my newly updated repeater to scroll to the right row. I've solved #1. I have a reliable method that will produce the newly added row's ClientID. However, problem #2 is proving to be tricky. I know I can just call ScriptManager.RegisterStartupScript() form my code-behind and it will execute the JavaScript on my page.
The problem I'm having is that it seems that it is executing that piece of JavaScript before (I'm guessing) the newly refreshed DOM elements have fully loaded. So, even though I am passing in the appropriate jQuery line to scroll to the element I want, it is erroring out for me because it can't find that element yet. Here is the line I'm using at the end of the method I posted above:
string clientID = getClientIdOfNewRow();
ScriptManager.RegisterStartupScript(this, typeof(Page), "ScrollScript", String.Format("$("#optionContainer").scrollTo("{0}", 800);", clientID), true);
What do I need to do so I can ensure that this line of JavaScript isn't called until the page with the UpdatePanel is truly ready?
I am experiencing problems with Forms Authentication. When I try to load my Login.aspx page neither javascript nor stylesheets do not load.

Im currently trying to use a jQuery plugin:jQuery Autocomplete TokenizerNow after posting back the page, I want to re-load the values back into the textbox for whatever items had been entered.Now the jQuery on the page is like below:

Old hand at ASP.NET, new to the UpdatePanel. I have a reporting page which executes a fairly length SQL query... takes about 10 seconds right now. What I would like to do is have my page fully render, with some placeholder text (Loading...) and then have the UpdatePanel kick off the actual time-consuming reporting process and render the report when it's done.
So... my theory is to use RegisterStartupScript() to kick this off and drop the string from GetPostBackEventReference() to trigger the UpdatePanel update. Some problems crop up:
1) Can I actually use GetPostBackEventReference w/ the UpdatePanel or do I need to trigger it some other way? Use this method on a button inside the Update Panel?
2) What event gets triggered when the postback reference is the UpdatePanel? It's not clear to me. I've got to call my databinding code somewhere! Again, maybe I need to use a button inside?
i have implemented an image preloader using javascript inside my mvc 2 web app, in order to display an animated "loading" image .gif while sequentially displaying page images.I have also implemented caching using a cache profile for the controller action that displays the specific page ([OutputCache(CacheProfile = "LongCache")]).The problem is that the image preloader javascript is called when caching is applied. I was wondering whether i could, somehow, use the image preloader code only when the page gets refreshed and not when the cached version is rendered.
View 2 RepliesI have the following code in my <head>
<% if(Context.User.IsInRole("Reseller")) {%>
<link href="<%: themelocation %>" rel="stylesheet" type="text/css" />
<%} else {%>
<link href="<%= Url.Content("~/Content/custom-theme/jquery-ui-1.8.5.custom.css") %>" rel="stylesheet" type="text/css" />
<%} %>
The issue is with themelocation, which is declared just above this block of code - like so:
<%
var reseller = new Reseller();
var storeSettings = new StoreSettings();
var themelocation = "";
if (Context.User.Identity.IsAuthenticated)
{
var resellerRepository = new ResellerRepository();
reseller = resellerRepository.GetResellerByUsername(Context.User.Identity.Name);
var storeSettingsRepository = new StoreSettingsRepository();
storeSettings = storeSettingsRepository.GetStoreSettings((int) reseller.StoreSettingsID);
themelocation = storeSettings.Theme.StylesheetLocation;
}
%>
Setting a break point shows that themelocation holds the string I need, but when the page is run - it generates a 400 - Bad Request error, and the net tab in firebug reveals its looking for this:
http://localhost:50982/%3C%:%20themelocation%20%%3E
Where am I going wrong here? Why is it using the variable name, and not what it contains?
I'm using ASP.NET MVC2, and all of this code is located on my master page.
i would like to use script manager and update panel in different domain to accommodate an other domain web site inside a iframe, but it prompts me a an error alert box (An error has occurred in this dialog. Error: 54 Permission Denied), may i know why?
Is that any solution to solve the problem?
Secondly, in the different domain, the JavaScript function EndRequest(sender, args) is not work after finish the loading whereas the InitializeRequest(sender, args) is work. May i know why?
I have a TxtBox and a DropDownList. Right now, the DDL contains 3 different items.
[Code]....
Instead of the string "001 was chosen", I would like to be able to load a .txt from the same server as the website, for instance sss/001.txt. So that the content of the txt file is being loaded into SSTLTxtBox.Text.
I've deployed a test project onto one of our web servers, and it doesn't appear that the CSS file is taking correctly. The page loads fine, but the styles aren't there. It looked fine in dev, but not now. Any thoughts on what's going on? I'm sure there is an easy solution, but I'm very new to the ASP.NET world.
