Javascript - Order Of CSS And Script Calls In A Aspx Page
Oct 19, 2010
Is there any specific order in which the external CSS or Scripts should be called in a aspx page which could help a bit in decreasing the page load time?
i.e
script type="text/javascript" src="../Includes/JavaScript/jquery.ui.tabs.js"
link href="../Includes/css/ui.all.css" rel="Stylesheet" type="text/css"
or
link href="../Includes/css/ui.all.css" rel="Stylesheet" type="text/css"
script type="text/javascript" src="../Includes/JavaScript/jquery.ui.tabs.js"

I have a method in a dll which fires of call to a wcf service after some processing. The aspx page has to make the dll method call and redirect back or redirect to another page.So I need to call the method asynchronously on the page load and then redirect without waiting. How do i do this??

I have an aspx application with 2 aspx pages. Second aspx page will get opened on click of a button in first aspx page using JavaScript. The problem is, when the second aspx page is getting opened, its Page_load event is not firing. Only when I refresh the second page, page_load event of second aspx page is fired. what might be the problem and what is to be done to fire the page_load event.

I have a static HTML page complete with client-side scripts and css (both are included in the html). I was wondering if it would be possible to embed this HTML page into an ASPX page and have the ASPX page be able to respond to javascript events that are raised from within the static html document? Does asp.net provide a specific control for this or can I use a frame?

I'm not conversant with JavaScript, however I need to refresh the page in few seconds so I want to use this code-
<script type="text/JavaScript">
<!--
function timedRefresh(timeoutPeriod) {
setTimeout("location.reload(true);", timeoutPeriod);
}
// -->
</script>
<body onload="JavaScript:timedRefresh(10000);">
<p>
This page will refresh every 10 seconds. This is because we're using the 'onload' event to call our function. We are passing in the value '5000', which equals 5 seconds.
</p>
</body>
Now my aspx page is using Content and referencing masterpage, Page Language="VB"
When I try to add this code to a new page it works fine and page refreshes as desired, but on existing page it gives error-ErrorValidation (XHTML 1.0 Transitional): Element 'body' cannot be nested within element 'td' ....

I have an ASP.NET page with two instances of the same Web User Control (a simple WYSIWYG editor). On submit, the WUCs do a little JavaScript magic and then proceed with a normal postback.
The first instance seems to be working, but the second fails to post changes back to the server (it reverts to the original, and posts that). I believe the problem is that the JS only fires for the first WUC. I've traced that to the following code, from the generated client-side source:
function WebForm_OnSubmit() {
prepHtml('AddEditPopup1_ctlEditorQuestion_txtEdit','AddEditPopup1_ctlEditorQuestion_divEdit', 'AddEditPopup1_ctlEditorQuestion_divHT' );
//snip...
}
The problem seems to be that there should be two calls to prepHtml: one for the ctlEditorQuestion instance of the WUC, and one for the ctlEditorAnswer instance.
Instead, there's only the one for ctlEditorQuestion. Both controls are registering the OnSubmit event, but one of them overwrites the other.The prepHtml call is registered from the WUCs' C# code at runtime:
//Page_Load
_onSubmit = String.Format("prepHtml('{0}','{1}', '{2}' );",
txtEdit.ClientID, divEdit.ClientID, divHT.ClientID);
//OnPreRender
Page.ClientScript.RegisterOnSubmitStatement(this.GetType(), "get-html", _onSubmit);
I should point out that I didn't write this control myself, and I've never seen this kind of runtime registration of OnSubmit JS code before. Page.ClientScript.RegisterOnSubmitStatement is totally new to me. I need to register both prepHtml calls so they run sequentially. Is this possible? I'm open to alternatives to Page.ClientScript.RegisterOnSubmitStatement, so long as the code still gets fired on submit.

First I am new to the asp.net world and am trying to figure out a weird issue that I am having. I have a page that has a form and on submit I launch another aspx file that exists in the same directory. The problem is the aspx file is shown and the file closes immediately! However, the weird part is if I make any modifications to the aspx file and save it and then run my application it works fine only the first time? Any subsequent submit actions launch the aspx page but then the aspx file immediately closes. But after I make some modifications to the aspx file..(simple ones) it launches correctly the first time. We are targeting .net version 4.0 and using IIS7. I am thinking that the asp worker process is doing something weird like checking for timestamps and closing it?!

I have this javascript
function myFunction(source) {
window.open(source, "Title", 'width=400, height=400');
}
and in c# code I call it by
HtmlPage.Window.Invoke("myFunction", source);
which opens up a aspx page and goes to its OnLoad function:
protected override void OnLoad(System.EventArgs e)
{
base.OnLoad(e);
how do I pass in parameters to the event args in the aspx page? or is that even possible? and how can I pass these parameters from my c# code to the javascript?

In an .aspx page with the vb.net codebehind i am using IFRAME , which would be created inside the repeater control. Since i want to resize the IFRAME based on the content within the page i have been using the resize function Obtained from here on the IFRAME onload as shown below.
<iframe id="IframeSubsectionArea" scrolling="auto" width="100%" onload="resizeIframeToFitContent(this)" runat="server">
However it is throwing the error as the method could not be found in the form. Is there any client side script variant for the onload event? May i know,What might be the reason for the error and its solution?

I've created a C# function which extracts data from an mssql database, formats it to a json string and returns that. Now I need to make a call from my javascript (jQuery) slider through an aspx page that is related to the C# code file. I have actually never done anything like this before, from what I could tell by googling I need to use xmlHttpRequest, but how exactly do I make the function get hold of this string? It would be awesome if someone had some example code that shows how this works.

How do i add my javascript file as an embeded resource to the page after the ajax javascript already on the page? NB want to do this part dynamically to have code wrapped up in usercontrol.
in aspx page: scriptmanager
Code: Assembly: WebResource("Functions.js", "text/javascript")
Code: onPreRender:
ScriptManager.RegisterClientScriptResource(Me.Page, Me.GetType().BaseType, "Functions.js")
This code successfully adds my javascript code to the page but not after the AJAX javascript and so not all of my functions work correctly.

I am currently building an asp.net webforms application in ASP.NET C# using Visual studio 2008 and the Framework .NET 3.5.In my application main page, I use some javascript code to make AJAX calls to different handlers (.ashx files) in order to get some information.In this handlers définition (in the CodeBehind), I use the Oracle provider for .NET (Oracle.DataAccess.Client) to get the requested information from an Oracle database.The thing is, when I make a first call to one of these handlers, everything works just fine, but when the main page try to repeat the call in order to update the information requested, I encounter a problem.In fact, it appears that the different Oracle SQL request results that were made during the first call are still in memory and that the requests are not repeated correctly in order to obtain the updated information from the database. The application keeps the first results and this is these results that are sent back to the main page once again.I don't know how to force the handler to obtain new results and work with it instead of working with the previous results.In the handlers définition, the IsReusable methods are all set to false.I have called the Dispose() méthods of every Oracle object at the hand of the handlers définition and then the System.GC.Collect() méthod to force Garbage Collection. But this does not seem to be sufficient to be sure that nothing is kept in memory.

I have the following Page_Load function...
protected void Page_Load(object sender, EventArgs e)
{
XmlDataSource1.Data = GetXmlFromFile(Request.QueryString["file"]);
XmlDataSource1.DataBind();
Repeater1.DataBind();
}
The page in which this Page_Load resides is called by a parent page. Each time this Page_Load gets called the value of "file" in the query string will be different. So each time I will be receiving the XML contents from a different file which are inserted into the XmlDataSource and then bound against by the Repeater. Getting the XML data from the file works great but when I bind against the repeater that only works the first time through Page_Load. Each time after that when this code is executed the same results from the first XML file are displayed in the repeater.
What am I missing here. How can I get the XML data to be bound against the repeater on each page load instead of just the first one?

I have a webservice (ASP.NET) deployed on a webfarm. A client application consumes it on daily basis. The problem is that some of its calls are duplicated (with difference of milliseconds). For example I have a function Foo(string a,string b). The client app calls this webmethod as Foo('test1','test2') once but my log shows that it is being called twice or sometimes 3 or 4 times randomly. Is this anything wrong with the webfarm or the code? Note that the webmethod has simple straighfarward insert and update statements.

I know how to call a simple old fashion asmx webservice webthod that returns a single value as a function return result. But what if I want to return multiple output params? My current approach is to separate the params by a dividing character and parse them on teh client. Is there a better way.
Here's how I return a single function result. How do I return multiple output values?
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="WebService.asmx" />

I have a user control (ascx) which contains a control (hidden field). In the page_load event of ascx, i have the below code:
HyperLink.Attributes.Add("onclick", "JavaScript:return AccessControl('" + hdnField.UniqueID + "');");
Note: The hidden field resides in .ascx file.
I want to access this hidden field at runtime and i have the below javascript function in aspx page that loads the usercontrol.
function AccessControl(hdnFieldId)
{
var ctrl = document.getElementById(hdnFieldId);
alert(ctrl);
I am getting 'null' value in the alert. I tried using 'ClientID' and 'this' instead of 'UniqueId'. I am wondering why this is not working. I am using .net 2.0.
