In Ext.net 1.2 and 1.3 this sample works fine


<ext:Panel ID="_pnl" runat="server" Flex="1" Layout="Fit" Width="250" Region="West"
Collapsible="true">
<AutoLoad Url="/ViewEngine/LoadWestMenu">
<Params>
<ext:Parameter Name="containerID" Value="#{_pnl}" Mode="Value" />
</Params>
</AutoLoad>
</ext:Panel>

When trying to upgrade to Ext.net 2.0


<ext:Panel ID="_pnl" runat="server" Flex="1" Layout="Fit" Width="250" Region="West"
Collapsible="true">
<Loader Url="/ViewEngine/LoadWestMenu" runat="server" Mode="Component">
<AjaxOptions>
<Params>
<ext:Parameter Name="containerID" Value="#{_pnl}" Mode="Value" />
</Params>
</AjaxOptions>
</Loader>
</ext:Panel>

In the ?LoadWestMenu? action the containerID parameter is null.
Any suggestion please?

Hi,

This is how you can load a component with

Mode="Component"

Example View

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<!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 runat="server">
<title>Ext.Net.MVC v2 Example</title>
</head>
<body>
<ext:ResourceManager runat="server" />
<ext:Panel
runat="server"
Width="250"
Height="250"
Layout="Fit">
<Loader
runat="server"
Url="/Test/Load"
Mode="Component" />
</ext:Panel>
</body>
</html>

Example Controller Action

public void Load()
{
Panel p = new Panel()
{
Html = "Hello World!"
};

ComponentLoader.Render(p);
}

Please update from SVN and use Params of Loader instead AjaxOptions params


<Loader Url="/ViewEngine/LoadWestMenu" runat="server" Mode="Component">
<Params>
<ext:Parameter Name="containerID" Value="#{_pnl}" Mode="Value" />
</Params>
</Loader>

Thanks Vladimir, but the parameter is always null
this is the Action code


public ContentResult LoadWestMenu(String containerID)
{
var contentResult = new ContentResult();
contentResult.Content = string.Format("<script>{0}</script>", _serviceWestMenu.CreateWestMenu()
.ToScript(RenderMode.AddTo, containerID));
return contentResult;
}

This method works fine but we need to pass parameter into the action url otherwise we need to implement an Action for each loader.

Hi Daniil,
When I add the Load listener, in firebug console I have this error


missing } in XML expression
...rm/', icon : el.iconCls });}}}},{iconCls:"#Information",text:"About",listeners:{...
and the rendering of the component does not succeed.

Did you update from SVN? It has been fixed recently.

Please ensure there is the new (updated) dll in your local project.

I was unable to reproduce the problem with the last Ext.NET sources.

Please give me the svn link to download the latest version because I'm working with Ext.NET 2.0 Beta Dll's.

Hi Daniil,

I do the last update, generated DLL version is 2.0.4483.23038 and the same error occurs.
Daniil
Apr 10, 2012, 12:17 PM
Are you sure the new DLL is affected to your project?

I've checked again - it works correctly on my side.

Please try with:

<ext:Parameter Name="containerId" Value="Panel1" Mode="Value" />
instead of

<ext:Parameter Name="containerId" Value="#{Panel1}" Mode="Value" />

Does it work? If yes, it means the old dll is used.

It doesn't work.
this is a simple code to reproduce the problem

Controller Action

public ContentResult Load(String containerID)
{
var contentResult = new ContentResult();
Panel p = new Panel("Title");
p.Height = 200;
p.Html = "Hello World";
contentResult.Content = string.Format("<script>{0}</script>", p
.ToScript(RenderMode.AddTo, containerID));
return contentResult;

}


<ext:Panel ID="_pnl" runat="server" Flex="1" Layout="Fit" Width="250" Region="West" Height="300"
Collapsible="true">
<Loader Url="/ViewEngine/Load" runat="server" Mode="Html">
<Params>
<ext:Parameter Name="containerID" Value="_pnl" Mode="Value" />
</Params>
<Listeners>
<Load Handler="eval(response.responseText);"/>
</Listeners>
</Loader>
</ext:Panel>

Well, your controller action code differs from the code in my example. The difference causes the error.

Anyways, we would recommend to use the example with

Mode="Component"
