I am using RadListBox to show a list of items. Each item has an icon. The requirement is jumping on the item when a the first letter of that item is pressed.
For example: It should focus on "Dock" when letter "D" is pressed
Is there any built-in feature to accomplish this>
This functionality is built into the RadListBox right out of the box.
You must have the list box focused and then type a key to select the item with the first letter matching the key that was pressed. In order to focus on the list box you can either: click with the mouse, tab to it, set focus in JS, or use the KeyboardNavigationSettings.CommandKey and KeyboardNavigationSettings.FocusKey to help aid with keyboard navigation.
Example:
RadListBox1 = new RadListBox()
RadListBox1.KeyboardNavigationSettings.CommandKey = KeyboardNavigationModifier.Alt;
RadListBox1.KeyboardNavigationSettings.FocusKey = KeyboardNavigationKey.L;
You can also use EnableMarkMatches to highlight more than one match if necessary and for typing more than one letter for selecting.
Reference: Telerik RadListBox Keyboard Navigation Demo << This has all the sample code you should need.
Seems this a Telerik bug, but i made a project, test situation and it's working.
download sample project here.
this project tested on google chrome Version 60.0.3112.113 (Official Build) (64-bit)
After run project press Alt+s or Alt+o or Alt+c
Remember change AccessKey property to change shortcut key:
RadListBox1.Items[0].AccessKey = "s";
I should say that this NOT a perfect solution.
RadListBox is a powerful ASP.NET AJAX control to display a list of items. It allows for multiple selection of items, reorder and transfer between two listboxes. Drag and drop is fully supported as well.

I have a window which shows a table on the left half. On the right half I display properties of the item which is selected in the table. The user can now change these properties.
The properties are represented by different kinds of controls: textFields, sliders, numberSteppers and popUpButtons.
The user can - besides using the mouse - use the tab key to navigate through the UI Elements. When the table has the focus tab will select the first editable item on the right side, then tab walks through the items and after the last item will go to the table again.
When the table has focus and I change the value of a popUpButton or move a sliderthe default behaviour of the API (Apple's Cocoa) is to change the value but keep the focus on the table.
My intuition would tell me that after changing a control element it should have the focus (i.e. become firstResponder). But I checked some of macOS' preference panes and they behave similarly.
In Apple's Human Interface Guidelines I do not find mention of that specific topic.
So my question is:
Is there a guideline or at least best practice an app should follow regarding if a control element like a popUpButton or slidershould get the focus when clicked or edited?
How to program a button which actually just should create another button with the same function like another existing one?

I want to add another Button with the same Funktion like the one on the top on the left side.
I know, it would be possible to just add several another buttons and switching visible to true and false, but that would mean that I had to add the elements manually and the number of these buttons would be limited which I would try to avoid.
You could do this using an extension...

I want to do an automation using Excel VBA. First of all I am not sure if its possible so I need to explain the problem first.
I would launch an application which has a list of reports , that one can run by right clicking on any of these and selecting an entry from the popup menu caled say "Run this report". The problem is the report names are displayed in a listbox.
There are so many entries I only need to run a few of them based on their names.
To achieve this I thought about placing the mouse cursor on the text displaying the appropriate report name and then trigger the right click event. These can be done using Windows APIs.
The challenge I am facing is how to hover my mouse on any particular list item based on its display text.
I can enumerate all the windows controls based on the handle of the application's window, but is it possible to get the location of any item on the screen based on the text displayed on list item.
I'm using the ListPicker from the latest Silverlight Toolkit on Mango
I've got a long list (100 items) of simple text items to choose between - using single item selection mode.
When I click on the ListPicker it opens up in full screen very nicely, but it doesn't scroll to the current selection.
This is a pain for the user - who typically wants to move from "item75" to "item76"
I've looked through the available properties, events and source code, but I can't see any obvious way to get the list to scroll the current selected item into list when the full screen mode opens.
Anyone got any ideas?
I found this Which may help, i hope it does!
in Depth ListPicker
See on MSDN what some of the events that can be triggered when selecting a Listpicker item and mess around with them, you may find a Very good Solution! :)
There didn't seem to be a way to do this with the current release - but the code is open source.
The current release also has a disadvantage of using StackPanel instead of VirtualizingStackPanel - so it is very slow at displaying long lists.
Instead of using this release, I ended up going with a different list selector http://priyarules.posterous.com/categorized-list-selector-for-windows-phone-7

Is there any way to maintain focus on menu after clicking a menu command?
Detailed version
Specifically, I've made a menu with some menu item with checked property. The problem is that each time I click checked menu item the menu lose its focus. It can be pretty annoying when there is a number of menu item with checked property and I want to manipulate them at once.
The most elegant solution for the problem would be maintaining focus on menu, but I can't find a way to apply it. Is it possible? And if so, what's the way to do that?
Even if there would a solution for it, sooner or later you will enter a situation in which a numerical or string property is changed via the menu, and then it becomes even impossible to keep the focus on the menu (while the dialog requesting the number or string is on the screen).
The first, simple alternative would be to put the checkable menu items on a toolbar or ribbon (just like Word does with Bold, Italic, Underline, ...). Numerical/string properties can then also be added on the toolbar or ribbon.
A second alternative could be to have a more complete configuration dialog in which the user can change all the configuration items. The configuration dialog can co-exist with the current checkable items, so users simply changing one check and users changing many properties all get a quick way of doing what they want.
