I know you can inherit from the Panel class and use the (MeasureOverride and ArrangeOverride) to measure and arrange the UI-Elements. But how does the Panel class render its content without any template?
Panel inherits from the FrameworkElement class which does not have the concept of template. So what causes it to render?

I have a class called Note, that consists of Title,Content and a Date. And inside listview item template, I have some text blocks and buttons. For now, I can apply animations when edit/remove button clicked, because that buttons' tag are the Grid which I will animate. Since my class is not a framework element, it doesn't have transform and opacity property. How to do so?

I had to use ItemContanerStyle
I have a page where I need to add components in specific order. (render it to a div)
Toolbar
Form
Toolbar
Grid
I have studied the doc and I got confused by all those layouts,containers and panels.
I not sure if I should create first some wrapping component(layout,panel) and then insert the components(form,toolbar,grid) or just create a div for each component ?
I would appreciate an example very much.
It depends on your application. If you are developing a pure (no html at all) extjs application the layout is handled by containers' layout but, if you are mixing html and extjs component, you can handle the layout with your div elements.
From your question it seems you are using html (and div elements) then you can handle it by your self. However, I recomend you create a container (a panel) with a hbox layout and include your componenets as children and let the panel handle the layout.
I have some GridPanel. Can I write a plugin which will create Panel with BorderLayout and push my grid to this Panel with region === 'center' and FormPanel with region === 'west', for example? In another words, I want to get my component and completely move it to another.
I believe you are asking to move a component after it has been rendered.
I would recommend setting up your BorderLayout with some more basic containers (or panels if you wish) for each region. Then add your grid and form panels to those containers rather than directly to the BorderLayout Panel.
At that point, you can simply get whichever component you want and .add() or .insert() it to some other container. In extjs 3.2.1, at least, add() and insert() both take care of the entire move. Don't remove() them.
I have a viewport with a tab panel in it. I'm trying to create a standard panel dynamically and make it visible. I'm able to create the panel and isVisible() returns true after calling doLayout on the viewport but the panel is not visible on the screen. Is there any way to make it visible (i.e., to hover above the tab panel)?
If you create the panel as a child of the document body and position it absolutely it should show above your existing layout. You could also (more easily) use an Ext.Window to do this.
I want to add my ToolBar inside the ToolBarPanel in codebehind.
I saw one example of Button & Canvas panel.
Here is the code:
Canvas.SetLeft(newButton, containerPoint.X - objectPoint.X);
Canvas.SetTop(newButton, containerPoint.Y - objectPoint.Y);
How can I achive samething with ToolBar & ToolBarPanelinstead of using Canvas & Button?
The code you gave is not adding the button to canvas, it sets extension properties that specify coordinates the button will be located at, if it is placed on Canvas panel.
ToolBarPanel is a primitive panel used by ToolBar to arrange its items. Unless you want to customize behavior you should be just using ToolBar optionally placing it into ToolBarTray.
ToolBar is an ItemsControl (just like ListBox for example), so to add a button from code, add it to panel's Items collection:
toolbar.Items.Add(newButton);
