How do you go about creating a complex servercontrol frontend?...I can't imagine you do Controls.Add() in the .cs files to add in divs, classes etc Can you embedd an ascx to make it easier to style?

I'm working on a Navigation Menu. I've created below ServerControl and it works, but I want to allow users adding some standard ASP.NET controls within my ServerControl Tags like label, image and so on.
<MdsMenu:ServerControlMenu ID="ServerControlMenu1" runat="server">
<MdsMenu:animation AnimationSpeed="Normal" AnimationType="Opacity_Height" Delay="1000" DropShadow="true" />
<!-- HERE HAS TO HAVE SOME STANDARD ASP.NET CONTROLS -->
<!-- e.g <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> -->
</MdsMenu:MenuItem>
</MdsMenu:ServerControlMenu>
My problem is here that how I can get Child Controls within <MdsMenu:MenuItem> and show them like as they are in the output. P.S: I overwrite RenderContents method
protected override void RenderContents(HtmlTextWriter output)
{
output.Write(OutPutStringBuilder.ToString());
}
I've written a ServerControl that contains a significant amount of javascript, and I'm using IScriptControl to pass parameters from the server code to the javascript. The javascript file is configured as an embedded resource, and a script reference to the file is being injected into the html by IScriptControl.GetScriptReferences(). The ServerControl is contained in a DLL assembly. When I use the control in a test page everything works fine.
What I want to do is to extend the control - to derive a new control from it, in a second assembly, that provides some extended functionality. (The first assembly contains code that is shared across customers, the second code that is shared across several projects for the same customer). So, my problem: I create a new ServerControl that derives from the first, but doesn't yet provide any new functionality.
[Code]....
Then I change my "<%@ Register ... %>" tag in the test page to reference the derived control. Things compile just fine, and the code-behind runs fine, but I get an undefined variable error in javascript. Sys.Application.add_init() is calling $create(), passing the <namespace>.<classname> of the javascript class, and it's throwing an error on the namespace.
Now, the namespace is registered on the first line of javascript file. Which makes it look like the javascript file might not be being included, when using the derived control. So I stuck a "debugging" line in front of the Type.registerNamespace(). Using the base control, the debugger breaks as it should. Using the derived control, it does not.
So, I look at the script includes in both versions of the page. They are identical. The sources are src="/testing/WebResource.axd?<random junk>", or src="/testing/ScriptResource.axd?<random junk", so I'm not sure which one refers to my embedded javascript file, but whichever one it is, the includes are identical between the page using the base control that works and the page using the derived control that does not.

I got a master page with a server control in it. Randomly the server control is inaccessible from codebehind. This doesn't happen on a specific action (eg a Button click or so). Currently I have no clue what this could be. I don't think it's output caching since this is not explcitly activated and the error happens far to seldom for that. But I'm going to disable caching in the master page explicitly with next deployment.
The control is defined in markup. The accompaning codebehind is:
PGFMainNavi.HasAccessToFunction = HasAccessToNaviItem;
// HasAccessToNavi is a local function
Exception is:
System.NullReferenceException: Object reference not set to an instance of an object
I have the following ListView:
<asp:ListView ID="procedureTicketList" runat="server" ...
<ItemTemplate>
<asp:GridView ID="MyGridView" runa...
How can I access to MyGridView programmatically ?
I have a gridview that contains check box in first column for each row. I also have a check box outside the grid view called >>>>
<asp:CheckBox ID="chkSelectAll" runat="server" Text="Select All" AutoPostBack="true"
OnCheckedChanged="chkSelectAll_CheckedChanged" />
I either can select more than one checkboxes from gridview then click on a button to get the number of checkboxes selected OR I click on SelectAll checkbox ( which is outside the gridview ) which check all the checkboxes in the gridview and give me the number of checkedboxes. When I select inidividual checkboxes inside the gridview, th e count of number of checkboxes is correct ( displayed in a lable ) However;
When I click "SelectAll" check box, it give me total of all checkboxes chekced in the
gridview + 1 ( extra ) I am trying to get rid of this extra one by checking if this "Allcheckbox" is selected to so I subtract one from the total count .. like this
// java code ... code not shown does capture the total count into c variable
varAllChecked = document.getElementById('chkSelectAll');
if (varAllChecked.checked== true)
litCount.innerText = c - 1;
else
litCount.innerText = c;
In a section in the <head> tags of my document I have code that lets me use the Id of my asp.net control from JavaScript like this:
<script language="javascript" type="text/javascript">
var customerId = '<%= Me.CustomerTextbox.ClientID %>';
</script>
However, if I want to modify the page structure in later stages of the page life cycle, it give me an error because I have the ASP tags in there. A work-around is enclosing the ASP tags in a server control like this:
<div id="customerIdContainer" runat="server">
<script language="javascript" type="text/javascript">
var customerId = '<%= Me.CustomerTextbox.ClientID %>';
</script>
</div>
But then I get a warning that a div tag is not allowed in the head tag. So is there a container tag that is valid in the head that I can add runat="server" to to make it a server control so I can workaround this problem without the warnings?
I've seen the <script type="text/C#> with intellisense.
If it is possible to script client side scripts in C#, some infomation or reference on how to do it. For example, do I need using statements, is the script compiled on the server.. etc.

I'm currently trying to setup testing with Selenium. It seems that Selenium sends a HEAD request to my route /Home/Index before it sends the GET request. This causes all my tests to fail. I was wondering how I would go about getting HEAD requests to respond correctly (not 404).
View 3 RepliesI just upgraded to VS2010 if that matters. I'm learning JQuery and noticed that scripts don't work if they're in the head tag. Also, I need the script tag with type="text/javascript" in the head (with nothing else) in order for the JQuery scripts in the body to work.
With a separate script tag in the <body> with my JQuery script, this works

I have seen on various websites how developers version their css/javascripts files by specifying querystrings similar to:
<head>
<link rel="stylesheet" href="css/style.css?v=1">
<script src="js/helper.js?v=1">
</head>
How is that done? Is it a good practice? I've been searching around but apparently, I'm not looking for the right terms. If it matters, I'm using ASP.NET.Edit:: I just noticed (via Firebug) that if I "version" my files (?v=1) they will always be loading and will always override the cache. Is there a way around that?
I'm successfully using a masterpage for all my .aspx's... the below is typical... where though can I place script such as this into my .aspx below since I don't really use a head/body?:
[code]....
I haven't been able to find relevant information through searches. I'm very green when it comes to sever side scripting. I have an ASPX page with a standard form. In the head I have meta tags, the title tag, and a link tag neatly ordered on their own lines. However, when viewing the source code after publishing to the server, the spacing between the tags is removed and it looks quite messy. (There are also <style> and <script> tags that follow, but they remain unaffected.)
I realize this has no practical effect on the site itself (in an SEO sense or otherwise). My project manager shows the source code to our clients to educate them on meta tags and page titles. It would help if it wouldn't become jumbled like this. I wonder if this is a common issue and if it's possible to prevent through better coding practices. HTML as authored, with tags separated on their own lines:
HTML Code:
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="description" content="Welcome to Lawn Care Waukesha - Cut My Lawn. Cut My Lawn - Lawn Care Services has offered quality lawn cutting, fertilizing, aerating, and much more at affordable pricing since 2002!

I'm not sure it's relevant, but here's the script used to send the form (which I didn't write, by the way). It's the final tag inside the page head:

I've never had to dynamically change the head of a webpage before and can't quite seem to get it. As mentioned in the title, the webpage is the child of a very simple master page. Here's what i've got:
[Code]....
I've tried :
Ctype(Me.Header.FindControl("head"), ContentPlaceHolder).InnerHtml
+= "<script type = 'text/javascript' src='" & Me.Master.get_root_rel() & "Sections/SectionJSFiles/EditFunctions.js' /></script>"
as well as
Me.Master.Head.InnerHtml += (same as above)
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 ?
[Code]....
set the width of the datagrid and hidden the head?
