This thread is now covering a few different issues, which might appear related, but I don't think are.

Yes, that was resolved. It was a typo on my end.

Excellent. Thanks for the update.

Even after this <ext:ResourcePlaceholder> issue is fixed, I don't think rendering the scripts/styles inside the <body> is the best solution. It might be better to set RenderScripts and RenderStyles to "None" on the ResourceManager, then manually include the require <script> and <style> includes into your custom rendered <head> block.

Example

<ext:ResourceManager runat="server" RenderScripts="None" RenderStyles="None" />

I'd recommend rendering the scripts/styles into the <head>, and I don't think this will be possible if your <head> section is rendered independently outside of the controls collection.

Geoffrey, I actually spent a couple of hours trying to render the scripts into the head. I have the ability to do that but there's no function on ResourceManager to get the scripts. If I set RenderScripts="None", ResourceManager.BuildScripts will not return them. I would like a way for ResourceManager to not add the script includes but still have an exposed function to retrieve them. The reason is that I have custom controls that has Resources property that register their client script files / css files to the ResourceManager. I have tried the following:

// pseudo code in my Page custom Render function...MyResourceManager initially has RenderScripts = None
MyResourceManager.RenderScripts = "Embedded"
//MyResourceManager.SetResources() -- this breaks because later on, it will get called again and it errors on dup keys
Me.AddToHead(MyResourceManager.BuildScripts())
MyResourceManager.RenderScripts = "None"

But that will only give me the default extjs adapter, extjs all, and extnet core. It wont give me any custom scripts for a particular control or extension that are part of the page.

any updates? just want to see what the time estimate is for a fix or a workaround so our qa team can continue testing.

Hi,

Can you update from SVN and retest (ResourcePlaceHolder must be outside the form)?
Also, now you can use the following code to get scripts if RenderScripts="None" (please note that list of scripts is built during render phase only)

ResourceManager1.BuildScripts(true)

Hi,

Just in case, here is the test cases

<%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
 
<script runat="server">
    protected void Page_Load(object sender, EventArgs e) {
        Response.AddHeader("Pragma", "no-cache");
        Response.Cache.SetCacheability(HttpCacheability.NoCache);

        this.Page.Controls.AddAt(this.Page.Controls.Count-1, new ResourcePlaceHolder());
    }
</script>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
</head>
<body>    
    <form id="form1" runat="server">
    <ext:ResourceManager ID="ResourceManager1" runat="server">
    </ext:ResourceManager>
    </form>
</body>
</html>

and

<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
 
<script runat="server">
    protected void Page_Load(object sender, EventArgs e) {
        Response.AddHeader("Pragma", "no-cache");
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
    }
</script>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head>
    <title></title>
</head>
<body>
    <ext:ResourcePlaceHolder ID="ResourcePlaceHolder1" runat="server">
    </ext:ResourcePlaceHolder>
    <form id="form1" runat="server">
    <ext:ResourceManager ID="ResourceManager1" runat="server">

BuildScripts(true) doesn't work. It still returns empty string if RenderScripts="None"

The switch statement in BuildScripts doesn't account for type = None.

  switch (type)
                {
                    case ResourceLocationType.Embedded:
                    case ResourceLocationType.CacheFly:
                        foreach (string item in items)
                        {
                            source.Append(string.Format(ResourceManager.ScriptIncludeTemplate, this.GetWebResourceUrl(ResourceManager.ASSEMBLYSLUG + item)));
                        }
                        break;
                    case ResourceLocationType.File:
                    case ResourceLocationType.CacheFlyAndFile:
                        foreach (string item in items)
                        {
                            source.Append(string.Format(ResourceManager.ScriptIncludeTemplate, this.ConvertToFilePath(ResourceManager.ASSEMBLYSLUG + item)));
                        }
                        break;
                }

Also, if I call BuildScripts during the rendering of my custom head, other controls' resources have not been registered yet. Here's what I think is happening:

Page Render
Head Render
Ext.Net.ResourceManager.BuildScripts(true)
Form Render
XControl Render
XControl.RegisterResources <-- this happens AFTER the head has been rendered so this controls' resources are never outputted

**Vladimir** · Aug 06, 2010, 1:32 PM

Hi,

Each control registers own resources during rendering, so, full list of scripts is available after last control rendering
Therefore BuildScripts method is not so useful for you.
What about to place ResourcePlaceHolder at the end of the body (like in my test case)?

this.Page.Controls.AddAt(this.Page.Controls.Count-1, new ResourcePlaceHolder());
