I have a design question:
If you had to make a WPF Combobox with search support,
(= combobox that shows a popup with some Buttons, Search TextBox, List.. etc
the selected item feed to the default's ComboBox TextBox.)
What would you do?
Write a custom control (diretly inheriting from System.Windows.Control)
Write a custom control inheritnig from Selector / ComboBox
Make a UserControl
Use a default ComboBox with a 'special Template' (CotnrolTemplate/Style ?) extended to search functionality
Use a default ComboBox with style and attached EventHandlers..
Thank you guys !
I have done that, and the method i used was option 2 - i did a template control inheriting from a third party combo, and replaced the popup contents with my own template.

I’m building a user control that has a context menu with several items, and I want the users of that control to be able to append items to that context menu.
I thought of adding an attached property where users can specify menu items, but I couldn’t find a way to easily add these items (e.g. in an ItemsControl container) to the control’s ContextMenu in an MVVM way (i.e. using binding and not code-behind).
Do you have an idea how this can be done?
If you have Dictionary<int,MenuItem> and you will have a place that user can select menus. Then add selected menu items to ContextMenu when your control loaded.
I hope this helps.
I have made one custom user control (search text box), which basically consists of one dock panel, and in the panel there are two controls: textbox and button.
I have set some default appearance for this control, which consists of setting a border on the user control, and setting no borders and no background on the textbox, and I have created a custom style for the button. So far this control looks the way I want, and is working correctly.
The problem arises when I want to allow themes for my application. When I put custom styles for basic windows controls (Button, TextBox, ListBox, etc), they are displayed properly with the new theme. But I don't know how to make a template for my custom control. Any attempt ended up in the control not showing at all at runtime.
What exactly must be done in the new template for this control? Do I need to make a template for the User control, and for the textbox and the button controls also?
You are mixing up user controls and custom controls here. What you described above is a user control, and you cannot apply new templates to it.
I'm trying to create a button in main window that would look like a globe, which would allow user to select his/her location. I want it to display a listBox when clicked on it just below the button itself.
Any hints on how to do this?
Probably the simplest way to do this is restyle a ComboBox and then restyle the ToggleButton in the ComboBox and remove the editable textbox.
This will avoid you having the implement the functions of the ComboBox for your popup.
Try using this as a starting point.
Another Approach would be to use the Expander Control with a list box in it

OR
You could play with the Listbox's visibility property
I was wondering if I can have a ComboxBox with a Treeview as the selector rather than a list?
I note that there is a ComboBox.ItemsPanelTemplate, but I don't know what I need to do to get this to work?
I could build a control 'from the ground-up' with a separate TextBox, Button and TreeView in a PopUp control, but wondered if there is an easier way.

Are you just wanting the combobox for presentation purposes regarding the treeview?
Why not use a treeview as is and just trigger the display via visibility or animation from a button or control of some sort?
I am working on similar theme as we speak. I am using the Expander control from the Silverlight Toolkit with a TreeView control inside it. When an item is selected in the TreeView, it sets the Header of the Expander and then collapses the Expander.
Initial tests indicate it's OK but as I say, just started with it myself. Will let you know if I hit any stumbling blocks.
is it possible to create a combobox in wpf from code, which I could position wherever I want on the window?
In my case, I basically want to create something like a Autocomplete for DataGrid rows,...
Thanks!
TextBox supports auto complete, and you can create your datagrid's template column and you can specify the template with textbox which can interact and give you autocompletion.
if you put it in a <Popup> you can then position the popup wherever you want--it is not "bound" by a parent container.
