Im creating a user control, for searching a treeview.
I would like to add the usercontrol to the top of the treeview.
I can achieve this by treeview.controls.add(mycontrol);
However my user control i placed on top of the tree and hidding parts of the tree. Can I somehow change placement of the tree inside the treeview. Or do i need another approach?
Just to clearify I do not want the usercontrol to be a part of the tree. I only want to display it on the top of the treeview

When starting my application I have in the form load event to expand the treeview control but it scrolls to bottom of the list. How do I get the treeview back to the top of the list of nodes.
In the form pictured below, the entire content of the right side changes when an item is selected on the left side. Which control can I use to accomplish this effect? I’ve tried a ListBox if anyone can put the code or the design tools .
Picture of form:
The left side is most likely a Win32 TreeView control. The pane on the right is almost certainly a ListView control.
There's really nothing that will automatically swap the views out when you click on the tree control. You'll have to write you own code to toggle the main pane's view based on the item selected in the tree.
IIRC, the Pivot control only loads a child PivotItem if it is the currently shown child. I would then guess that the previously seen child is also somehow unloaded, presumably still stored in memory, but hidden from the UI.
What I'm wondering is, how does the Pivot control dynamically load/unload a child control, and can that behavior be imitated within a custom UserControl? As for unloading, is it as simple as collapsing the previous child's visibility, or is something trickier going on?
That is to say, supposing I use my own UserControl like:
<my:CustomUserControl>
<TextBlock x:Name="_textBlock" Text="wait for it ..." />
</my:CustomUserControl>
Normally, the child TextBlock is instantiated when the surrounding PhoneApplicationPage is instantiated, via InitializeComponent and all that. Is there any way to postpone this behavior and load the child programmatically?
Easy way to achive your goal is to use ContentControl with template. It will create all controls only after setting Contenp property.
Or you can simply inherit your control from Panel and add child controls in code.
I am re-designing some GUI items and want to implement something like the following:
As you change options in the TreeView on the left, the controls on the right change according to the option selected.
My question is, what is the best way to implement this? I was thinking of setting the visible property to true / false for each control to it's respective TreeView option selection; however, designing this on the VS GUI editor would be pretty painful as there would be hundreds of controls all over the place and on top of each other.
User controls. Create the blocks you have outlined in red as user controls and add/remove as you select/change node in the treeview.
If you want a "buffer" effect to avoid flicker when removing an existing control, then use a tab control with two pages (without showing the tabs.) Start with showing TAB1 then when selecting a node in the treeview add the correct control to TAB2 and then make TAB2 the active page. And then remove any existing controls from TAB1. And then the other way around when the next node is selected. etc etc.

I have a treeview derived control, and I want this tree view to be
shown with a background image.What should I do in order to display a background image behind the tree and still view the tree nodes?
the default TreeView control doesn't support backgrounds
