[CLOSED] PagingToolbar plugin ownerCt

[softmachine2011]

Hi,

In Ext.NET v1.3 I had a plugin that could be used like this inside a GridPanel or TreePanel

<BottomBar>
                    <ext:PagingToolbar ID="GruposCalendariosPager" runat="server">
                        <Plugins>
                            <SoftMachine:IndexServerPagingToolbar runat="server" />
                        </Plugins>
                    </ext:PagingToolbar>
                </BottomBar>

And this is my plugin code (example):

Ext.namespace('Ext.ux.netbox');

Ext.ux.netbox.IndexServerPagingToolbar = function (config) {
    //Nothing
};

Ext.ux.netbox.IndexServerPagingToolbar.prototype = {
    //Instancia del control PagingToolbar
    controlPagingToolbar: null,

    init: function (control) {
        if (control.ownerCt.xtype == "netgrid") {
           //Some Code
         }
    }
};
Ext.ux.IndexServerPagingToolbar = Ext.ux.netbox.IndexServerPagingToolbar;

But control.ownerCt is undefined right now. How can I obtain ownerCt to access xtype and other properties?

Hi,

It has been changed due to the changes in the widget life cycle. Now its plugins are initialized before it has the ownerCt reference.

The ownerCt appears when a widget is added to the container. So, I can suggest to use the widget Added listener to initialize the plugin.

Example

<ext:PagingToolbar runat="server">
    <Listeners>
        <Added Handler="new Ext.ux.netbox.IndexServerPagingToolbar().init(this);" />
    </Listeners>
</ext:PagingToolbar>

Also, please note that we didn't create a separate class for GridPanel in v2, so, this

control.ownerCt.xtype

will be "gridpanel" for <ext:GridPanel> as for a common ExtJS grid.

With this workaround plugin will be initialized two times right?
And to difference it ownerCt is present in added event, right?

Well, yes, if you will leave Plugins section. But you should remove it in the case when you initialize the plugin within the Added listener.

Yes, you can access ownerCt within the Added listener.

Even mode, the container is passed as an argument.

Well, removing plugins section Ext.ux.netbox.IndexServerPagingToolbar doesn't exists. How I have to add it? Like a regular JS in a centralized master page or there is another way to load it for plugins?

I would recommend to check ownerCt in js and if it empty then listen 'added' event

Something like this (did not test it)

init: function (control) {
if (!control.ownerCt) {    control.on("added", this.init, this, {single:true});  
    return; 
 }


   if (control.ownerCt.xtype == "grid") {
       
   }
}

Agree, it would be more consistent.

Yes, just a common JavaScript file.

Or you even could implement a custom control, here is the example.

The problem is that I have server side code for the control since original version (ext.net v1.3) but removing plugin section, it doesn't initialize the assembly information or maybe it is done after added event. I don't know

here's my plugin code

using System.ComponentModel;
using System.Collections.Generic;
using System.Web.UI;
using System.Xml.Serialization;
using Newtonsoft.Json;

[assembly: WebResource("Softmachine.Millenium.Presentation.Web.MVC.Client.Resources.js.WebControls.IndexServerPagingToolbar.js", "text/javascript")]

        protected override List<ResourceItem> Resources
        {
            get
            {
                List<ResourceItem> baseList = base.Resources;

                baseList.Capacity += 1;

                ClientScriptItem _csi = new ClientScriptItem(
                    this.GetType(),
                    "Softmachine.Millenium.Presentation.Web.MVC.Client.Resources.js.WebControls.IndexServerPagingToolbar.js",
                    "/ux/plugins/indexserverpagingtoolbar/indexserverpagingtoolbar.js");

                baseList.Add(_csi);

                return baseList;
            }
        }

            {
                return "Ext.ux.netbox.IndexServerPagingToolbar";
            }
        }

        {

            {
                ConfigOptionsCollection list = base.ConfigOptions;

                return list;
            }
        }
    }
}

Any idea?

Can you see a resource request? What is its URL and response?

No, with developer tools of IE9 in network there isn't any request to this JS, but with plugin section the request is done correctly.
