WPF controls not visible in Visual Studio - wpf

I created a UI by dragging and dropping controls from the toolbox in Visual Studio and got the following as I expected.
And then I modified the XAML to embedded within a proper grid hierarchy. Now all the controls except the menu are not visible in the UI. But I can still select them in the designer as below.
How can I resolve this?

Visual Studio show control properties and events at the same time

For Controls in WinForms while using the designer I would like to display both Properties and Events for a control at the same time.
The New Window option is greyed out in Visual Studios Window Drop down when the properties window has focus not allowing me to create a second instance.
I find I spend a lot of time switching between the two. I use the form designer extensively and events to navigate to specific code quickly. Any help would be appreciated!

WinForms.net: a control for one project only

I want to make a composite control which I could drag to form multiple times, but this control should reside in one project only. I do not like the idea of making a control, and installing it to be visible to all projects in a Visual Studio 2010 Toolbox.
So, I assumed that the UserControl is what I needed. I created one, but now can't drag it to a form or find it in the Toolbox.
Tools > Options > Windows Forms Designer > AutoToolboxPopulate is set to True.
I had to compile the project to make UserControl appear in the Toolbox.

Windows.Forms.DataGrid missing from Toolbox in VS2008

I am trying to add a DataGrid to my Windows Forms application and it seems that it is missing from the toolbox. Only DataGridView is available.
PS: I was able to manually add it to designer code. But nevertheless I am curious as to why it's not included in the toolbox.
I suspect the DataGrid was never in the Toolbox to begin with. According to MSDN, the DataGrid
Displays ADO.NET data in a scrollable grid. The DataGridView control
replaces and adds functionality to the DataGrid control; however, the
DataGrid control is retained for both backward compatibility and
future use, if you choose.
Also, you should note that Visual Studio allows you to customize the items in the Toolbox. You can right click in the Toolbox, select "Choose Items" and then select DataGrid so that it will then appear in your toolbox.

Does anyone knows how Microsoft default WPF controls are loaded into Visual Studio's Toolbox?

When the WPF window is opened in design view in Visual Studio, the Toolbox pane automatically loads WPF controls into "Common WPF Controls" tab and "All WPF Controls" tab.
Does anyone know how Visual Studio does this?
Seems like they would be loaded through either the Project References or the (more likely) user options saved when you rightclick on the tookbox and choose "Choose Items...".
I would imagine that somewhere, there is a setting where by default when a XAML page is open, it loads a bunch of items in System.Windows.Controls into the Toolbox. If you want, you can deselect those items you dont want, and put different items in the toolbox

You can find it at the Common WPF Controls section in your Toolbox as you can see below. Just drag-and-drop it into your window designer and everything will be okay:
Update
Then do the following steps:
Right click on your Toolbox and click on Choose Items...
Filter the long list on the opened form by typing DataGrid as you can see on the image below:
