[CLOSED] MVC Custom Control using Builder framework - Loader problem
Hi,
This question/problem builds on from this thread where Vladimir showed how a custom Ext.NET component can be exposed in MVC Razor using a class that implements IHtmlString: http://forums.ext.net/showthread.php...as-MVC-Helpers
The previous post is really handy but I wanted to go a step further. In the previous post I can do something like this with Razor:
So I gave it a go (using a custom window example). From an intellisense perspective, it worked, and I could do something like this:
Some code to reproduce:
1) CustomWindow class (C#)
4) Example of it being successfully used in WebForms:
a) Adding Builder support to Custom Window:
However, if I browse the above template (assuming controller for it is created!) Firebug reports the following:
"Error: Ext.Loader is not enabled, so dependencies cannot be resolved dynamically. Missing required class: MyApp.CustomWindow"
When I look at the source code, indeed, the custom resource is not loaded (though it is if I use the WebForms approach -- or ControlRender approach as per the previous thread I mention at the top of this one).
Even if I add ResourceManager.RegisterControlResources<Custom Window>(); into the builder factory methods it still doesn't help.
Any thoughts? I've probably missed something when looking at your source code...
(Second question, I found I had to set the ID of the custom window - see where I used Guid.NewGuid(). If I didn't do that I got a different error saying Widget needs an ID. I couldn't see in your code how you addressed that without my "hack". Any insight into that would also be appreciated!)

The previous post is really handy but I wanted to go a step further. In the previous post I can do something like this with Razor:
@Html.FinancialGrid(400, 500);So I gave it a go (using a custom window example). From an intellisense perspective, it worked, and I could do something like this:
@Html.MyApp().CustomWindow().SetHeight(100).SetWidth(150)Some code to reproduce:
1) CustomWindow class (C#)
public partial class CustomWindow : Window
{
internal const string JsResource = "Ext.Net2.Tests.CustomCode.CustomWindow.CustomWindow.js";
public override string InstanceOf
{
get { return "MyApp.CustomWindow"; }
}
public override string XType
{
get { return "customwindow"; }
}
protected override List<ResourceItem> Resources
{
get
{
List<ResourceItem> baseList = base.Resources;
baseList.Capacity += 1;
baseList.Add(new ClientScriptItem(typeof(CustomWindow), JsResource, ""));
return baseList;
}
}
protected override void OnInit(EventArgs e)
{
Title = "My window";
Layout = "fit";
Border = false;
Items.Add(new Panel { Html = "Example" });
base.OnInit(e);
}
}Ext.define('MyApp.CustomWindow', {
extend: 'Ext.window.Window',
alias: 'customwindow'
});4) Example of it being successfully used in WebForms:
<cc1:CustomWindow runat="server" Height="100" Width="150" />a) Adding Builder support to Custom Window:

public Builder(Config config) : base(new CustomWindow(config)) { }

new public class Config : Window.Config
