In Delphi, there is RadioGroup control but not in Delphi Prism. Do you know if there is any similar control for Delphi prism? I have searched my toolbox and all I can find is CheckedListBox. I have been using it and this control is not functioning the same way as RadioGroup control.
In WinForms the standard way to do this is to add a group box and then add radio buttons to that group box. The radio buttons will automatically be grouped. But there's nothing like the VCL ItemIndex property so you'll have to use the Checked property of each radio button to determine which item is selected.
I believe that most of the 3rd party component vendors (e.g. devexpress) fill this gap in the standard component set by providing radio group controls similar to that found in the VCL.

I want to use comobox which is editable in my silverlight project, but silverlight doesnt provide a such control.
If any one knows how to create a custom editable combobox in silvelight 4.0 then please help me.
Editable combobox means:
A combo box providing list of
options.
User can enter the value.
Filtering.
Sounds like you are looking for the AutoCompleteBox.
Allows user to type value
Can simply dropdown like a combox
Partial value typed can be used to filter choices using either StartsWith or Contains mode.
Supports a create new entry operation if the final typed value does not match any existing entry
This control is part of the standard SDK and is found in the System.Windows.Controls.Input.dll. You should be able to drag it from the toolbox.

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.
Silverlight 4 has a new ContextMenu control in the latest toolkit.
I can't find any examples anywhere on how to reliably use this ContextMenu on a DataGrid row. Theres a tonne of context menus out there but I want to use the new version from the toolkit.
I'd like to be able to set context menus for rows as well as cells.
The only way I've found is to manually create the menu on right click and show it, but I'd like to do it in XAML.
Note: You need to currently use this workaround to avoid binding problems when using ContextMenu in XAML for a datagrid cell.
The developer of the Toolkit's ContextMenu wrote this article, specifically talking about using it with a DataGrid Delay's Blog
You can use this open source multi-level menu and context menu as alternative:
www.sl4popupmenu.codeplex.com
The demo on the main page shows how to do it in code. But you can also create the menu anywhere in your XAML like any other control and then associate it with the Datagrid using the RightClickElements property. The control will then handle everything else for you.
I'm trying to create a custom UserControl that will mimic auto-complete as it works within Intellisense using WPF. I'm using a TextBox and a Popup containing a ListBox within my control.
I want to be able to keep keyboard focus set on the TextBox irrespective of whether or not the auto-completion popup is open so that a user can continue typing whilst simultaneously using up/down controls or the mouse to select elements in the popup to autocomplete the text. Is there any way this can be done in WPF?
Check out my article on CodeProject, it addresses the issue of the popup specifically.
A Reusable WPF Autocomplete TextBox
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.
