View 2 RepliesI 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?
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?
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.
View 2 RepliesI 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.
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?
I have a tab control on my page and on click of tab user control is loaded dynamically.I need to load the javascript file of that user control dynamically. I don't want to add the reference of my js file on parent page.so in my .ascx page load event i added:
System.Web.UI.HtmlControls.HtmlGenericControl js = new System.Web.UI.HtmlControls.HtmlGenericControl("script");
js.Attributes["type"] = "text/javascript";
js.Attributes["src"] = "../../js/DatesJavaScript.js";
Page.Header.Controls.Add(js);
but it is not working.
I have several hundred html files that I want to remove the <head></head> tag from and all information contained in the tag. I am fairly sure I can do this in Visual Studio using the Find and Replace In Files with REGEX.

I want the first 6 line of my javascript file run at runtime. But I recieve error at runtime:

I have a page called main.apsx and on that page I have a multiview with a couple of view panes. In main.aspx I also have an have a buttons.ascx file with a few link buttons. When these buttons are clicked I want them to show the the selected view panels in multiview in main.aspx.
I cant seem to figure out where to put the action code for the link buttons. Do I put it into my buttons.ascx.cs file or into main.aspx.cs? I presume in buttons.ascx.cs, but if I do that, how will the buttons find the multiview control?
This is the code for on of my buttons in buttons.ascx.cs
[Code]....
When I run it like this is gives an error
The name 'MultiView1' does not exist in the current
The name 'View1' does not exist in the current

View 2 RepliesModal 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++;
}

Now the weird thing is I have a user control UserControl1 in which I put some JavaScrdipt logic there, and I have another user control UserControl2 and I registered both in the page called Page1.aspx.I would like to call the JavaScript function resided in UserControl1 from UserControl2, however, I got an error saying the function is not defined. I think both user controls are loaded before I use them then I think the JavaScript function can been seen anyway in that page.
View 1 RepliesI 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...
I want to move some parts of the html page containing this function to a new web user control. now "form1" is not defined and it is not working correctly without any error message!

I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page
and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
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 ?

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" />

is it possible to get the ID assigned to User Control from the control using javascript or jquery.
