I need to be able to add an external js file for a user control (using
this.Page.ClientScript.RegisterClientScriptInclude("SuggestionSearch",
"~/Secure/Shared/SuggestionSearch.js");
syntax)
But it puts the javascript file on the page too early... is there a way to put the file at the bottom of the page?
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.
On load I'm both calling a JavaScript setTimeout() function that will hide a .NET Panel control, and hiding it in the code behind on first load. Clicking the save button will set the Panel to visible then reload the page at which point a setTimeout() function is called... so basically you click save, and see a panel with "Details Saved" for three seconds, at which point it disappears.
The problem is the external JavaScript file can't find _pDivAlert.ClientID (I've debugged and it returns null). It only works when the code is in a tag in the .aspx page. how I can either pass the client ID to the HideControl() function or find the ClientID from the external JS file?
Here's my code:

I am getting an error while calling a javascript from a dropdownlist which is placed inside a modal pop-up panel. if i am ebeding a small script like onchange="javascript:alert('hello');", it works fine. But if i m using <script> </script> for embeding a javascript its showing 'object doesn't support this property' error. when i debugged it the compiler does not get into the javascript function.
Below is a screenshot of that page.
I'm customizing a NopCommerce store, and am using a gridview to display and sort the products. All that works well. I like how the external pager (user control) works with the gridview, with one exception -- it uses the hyperlink control, so I lost viewstate, which I need to retain for both the search page and to retain the gridview sort options. Based on the page selected (from the pager control), I query the database and rebind the gridview. So, I switched the user control to use LinkButtons instead of Hyperlinks. This is the sample code for one of the buttons:

I set a breakpoint inside the lbCommandClick method, but it never gets hit. Reading other posts tells me that I would have to add the dynamic controls in the OnLoad method, but since this all happens based on other data on the page (say search results), I don't think I can do it onLoad. However, the link buttons do work to cause a postback, and my viewstate is saved correctly. The only problem is that I do not know which button was clicked. I could check Request.Params["__EVENTTARGET"] onLoad, but that is kind of a hack -- I'd much rather be able to set the event handler in the user control and use the CommandArgument property. But, what I have tried so far fails.
Especially one that would allow me to set the EventHandler in the User Control? (e.g. OnlbCommand="PagerLBPageChange" )
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 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 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...

View 3 RepliesI have an external JavaScript in an asp.net 3.5 project. While writing different functions, sometimes the JavaScript is loaded into FF and sometimes it is not (based on FireBug) and the JavaScript does not run.
Even if there is an error in the JS it should still load or be visible to the browser, right?
What is the logic behind when it is loaded and when it doesn't load (or is accessible to the browser?)

I have a code like
var mySession = "<%= Session["MyID"] %>";
alert ( mySession );
and when I place this code in my aspx page inside a script tag, it works fine. But it doesn't work in an external js file. I am not able to figure out the problem.
Is there anything wrong in my code, or is it like this by default?
How can I make a call on a function of an external javascript file?
More specific...
In the head tag i have
<script type="text/javascript" src="JScript/FontSize.js"></script>
The external javascript file, (that i would like to call) FontSize.js contains the following functions.

Of course nothing works as it should because, i do not know how to make the call to a function to an external js file
I have settings in AppSettings (web.config) and I need to pass them to an external javascript file.
In ASP.NET I would think of an ASHX handler to write the javascript file to the response replacing placeholders with the settings values.
I need to access controls of aspx page and usercontrol page through the external .js file. I created a global varaible in the aspx page
<script language="javascript" type="text/javascript">
var loadPanelID = "<%=ajaxLoadingPanel.ClientID%>";
</script>
Now I pass this value in the onclick event of button click (Let the funtion name be Fun(loadPanelID) ) . The controls is recognised in the .js file. Everything is fine till now. Now i need to call the same javascript method Fun() from the button click of usercontrol.
<script language="javascript" type="text/javascript">
var loadPanelID = "<%=ajaxLoadingPanel1.ClientID%>";
</script>
I have ajaxLoadingPanel1 in the usercontrol and I have defined global variable as in the first one in ascx and passed that value to Fun() method. But this time it gives error called "loadpanelID" is undefined.
I have a Site.Master in my ASP.NET project which defines a HEAD section as follows
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title id="MasterTitle">MyApp</title>
<link rel="icon" href="Content/icon.ico" type="image/x-icon" />
<link href="Content/mycss.css" rel="stylesheet" type="text/css" />
<script src="Content/mycode.js" type="text/javascript"></script>
</head>
In the mycode.js file, I have a function called GetSels();
function GetSels()
{
//do stuff
}
If the GetSels function is defined in Site.Master, GetSels is callable. If it's in mycode.js, it's not. Every code example I've seen seems to say this should work.

I'm working on a C# web app and I've to handle some javascript code.
I can do it both using javascript injection from my .cs file, which I'm doing now or choose to include my code into an external js file.
I would like to know when you would prefer to choose one way over the other.
According to me, it can be more clear to put code in external .js file and it can ease debugging.
Code injection from code-behind would however keep together all the necessary code for my component.

I'm using visual studio 2010 professional. I have my javascript files in a subdirectory called javascripts where I am holding all those files respectively. I am constantly having to remove (from the head section) the external javascript link. Then rename the javascript file in the javascript's folder, then re-add the external file back to the head section again. The reason of having to do this is somethimes when I am editing the js file, and then go to test it, the aspx page doesnt seem to see the code anymore. I've tried different browsers, closing the window and reopening, deleting temp int files, but all to no success. Has anyone else had this happen, is there a better workaround??if i open the js file in the browser, the functions are showing properly.

View 4 RepliesI've written a user control that has a button that a user can click to display an additional DIV. I discovered that it would be nice to make the control remember whether or not the DIV is visible after postback so that when the page reloads, the DIV stays visible if the user wants it that way.
What is a good way to implement this with jQuery at my disposal?
