Custom Control Render JavaScript Code In Head Tags?

Feb 3, 2011

I am creating a custom control and was wondering if it is possible to render any JavaScript in the head tags of the page it is placed on? I am thinking I would need to use the FindControl method, but am not sure what I need to bind to. I am thinking the page object? Let me know if I am thinking in the right direction or if there is another option.

My only concern with the above mentioned idea is that how do I render all my content while placing some code in the head tags?

Inject Code Into Masterpage / Html Head From A User Control?

Jan 10, 2010

I am struggling with something that I guess should be standard practice really. I have a number of user controls that use some JQuery plugins. I do not really want to link to the extra CSS and JS files from my main masterpage as this would cause extra load to the user the first time they hit the site, (admittedly it would only be the once), so I was just putting them links into the top of the user control. Then I looked at my source HTML, not nice! Even worse for controls that repeat multiple times on a page.

So I was thinking is there a way of injecting them into the Head of the page when they are needed from the User Control. For that matter is there a way of doing it to the footer for JS stuff?

Web User Control With Javascript Used Multiple Times On A Page - How To Make Javascript Functions Point At The Correct Controls

Apr 12, 2010

I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.

C# - Get Clientid In User Control From External Javascript File?

Mar 23, 2010

I am developing a user control (ascx) in ASP.NET which uses javascript for manipulating controls. Currently the javascript code is inlined and uses <%= somecontrol.ClientID %> to get the control it needs.

I want to put the javascript file in external file but from external file I cannot use the above syntax for retrieving controls. I have read about possible solutions in this and this answers but the problem is that the user control can be placed multiple times on page. This means that the Controls array (mentioned in the answers) will be rendered several times with different items. As a result the script will not be able to retrieve the id it needs. If I put <%= ClientId %> in the name of array that holds items then I will have the same problem as I am trying to solve.

C# - Determine If A JavaScript File Is Already Included Via User Control?

Jan 20, 2010

I'm building several user controls (ASCX) for my website and several of them are very similar in what they do. (As a side note, I must create unique UC's even if they're similar because I'm creating widgets for the new Telligent Community themeing system). For example, two of them are different but use the same front-end code to create a 2 or 3 tab panel where you can click a tab and it changes the data below. I have a single JS file to handle these tabs and the animations. I'm currently dynamically adding my JS file reference to the <head> from the user controls' code via:

Literal jsFile = new Literal();
jsFile.Text = string.Format("<script src="{0}"></script>", "/community/themes/test/js/tabbedCallout.js");
Page.Header.Controls.Add(jsFile);

If I have both of these controls on a page though, both will add this JS file reference. How can I do a check to see if it is already added from another control?

AJAX :: Modal User Control On Top Of A Modal Popup + Javascript Causes Page Flash

Jul 29, 2010

Modal Popup user control (its a message box) on top of a modal popup with javascript that maintains postback on a scrollable div all inside of an update panel causes my page to flash on postback of the user control. If any one of the peices (user control, modal popup, javascript) are missing everything works fine. The javascript is maintaing scrollback on a scrollable listview on the page. A modalpopup is shown on top of this main page that is for report parameters. The user control is used for validation and is displayed if a parameter is invalid. I know this may not be the best design, but it can't really change unless its a minor change. Heres the js if anyone wants to see popup or styles let me know.

//Begin methods to maintain or reset scroll position during postback.
var controlIds = [];
var scrollTops = [];
//Register a control to maintain its scroll position on postbacks.
function MaintainPostback(controlId) {
controlIds.push(controlId);
}
//Find the div/control id in the controlIds array and set its scroll position to 0.
function ResetControlScrollTop(controlId) {
var index = 0;
while (index < controlIds.length) {
if (controlId == controlIds[index]) {
scrollTops[index] = 0;
return;
}
index++;
}
}............

JavaScript - User Control JavaScript Function Doesn't Run

Sep 22, 2010

I have the function put here like below:

$(document).ready(function () {
UserControlNameInit();
});

The script are put in the following and the block is in the .ascx page.

<script type="text/javascript">
</script>

However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.

I did the same way with other user controls, and it works. Just 1-3 user controls are not working...

C# - Angle Brackets In Page Head Element?

Mar 1, 2011

PHP experience (which meaby is causing this problem) and Iam having small problem passing data from codebehind to view-source.

I declared string variable on codebehind side such as:

...
public string mystring = "Scotty";
protected void Page_Load(object sender, EventArgs e)
{
...

So now I want to use it in view-code but when I put it in angle brackets (<%: or <%=) and put it in head element I got no access to this value. On the other hand when I put it in BODY element everything is ok.
My failing example (simplified):

<head runat="server">
<script language="javascript">
function beamMeUp()
{
alert(<%=mystring;%>);
}
</script>
</head>
<body>
<input type="button" onclick="javascript:beamMeUp" value="Warp6" />
</body>

why I can't use it (the <%=mystring;%>) in HEAD but i can use it in BODY ?

Cannot Use Response.Write In <head> Section Of Aspx Page?

Feb 18, 2010

I'm trying to use the Response.Write() method to dynamically insert content in the < head > section of an aspx page. I need to inject a string value from a property on a code-behind object which is a link to my CSS file. However, it is not being processed properly at run time. The object is public on the class and is hydrated in the Page_Load() event. Down in the body of the page I can successfully inject other properties from the Corpoartion object with no problem at all.Why does this not work in the < head > section?This is the part that does not expand correctly:

<link href="<%= Corporation.PageStyleSheet %>" rel="stylesheet" type="text/css" />

Here is the entire < head > section:

<head runat="server">
<title></title>
<link href="<%= Corporation.PageStyleSheet %>" rel="stylesheet" type="text/css" />
