How can I programatically trigger the tab key functionality in a VB.Net windows application?
Currently in my application I am using one splitter when I press the tab key, and the focus is moving in the right order.
However I need to use arrow keys to move the focus to next controls, in the same way that the focus is going when the user presses the tab keys.
Thanks in Advance
You can simulate the SendKeys.Send(string) method (in the Systems.Windows.Forms namespace). To simulate a tab keypress you would call SendKeys.Send("{TAB}").
To see all the key codes, check out http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.aspx
Better late, than never, since i found this post looking for a solution to a similar problem.
Windows Form type has ContainerControl somewhere in its chain of inheritance and that has a method ProcessTabKey(Boolean trueForForward) . It does exactly what you need, inside your form instance this.ProcessTabKey(true) will move focus forward along the tab index and this.ProcessTabKey(false) will move it backward.
Very simple code
Write Down this in KeyDown Event of Datagridview
If e.KeyCode = Keys.Enter Then
' Your code here
SendKeys.Send("{TAB}")
e.Handled = True
End If

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.
In Keyboard Extension, in UIInputViewController, I can get notified through textDidChange(textInput: UITextInput) of any change, and use self.textDocumentProxy.documentContextBefore/AfterInput to get current text.
Problem arise when user 'select text'. The 'before' and 'after' "sees" only the part before and after selection.
Is there any way to know if user touched any of the Copy-Cut-Select in a textField (given - we don't have access to that field from Keyboard Extension)?
Something like:
if(self.textDocumentProxy.someProperty == UIDocumentProxyTextCut)
Or any other way to know which of the UITextField action (Copy/Cut/Select) did the user took?
I think we can not find out if user touched on Copy/Cut/Paste menu
Because a custom keyboard can draw only within the primary view of its
UIInputViewController object, it cannot select text. Text selection is
under the control of the app that is using the keyboard. If that app
provides an editing menu interface (such as for Cut, Copy, and Paste),
the keyboard has no access to it. A custom keyboard cannot offer
inline autocorrection controls near the insertion point.

P/s:
I saw self.textDocumentProxy.documentContextAfterInput is always NIL. Who know why?
How can we know where the cursor is to provide suggestion for user?
Basically, I want to bind a certain letter to scroll up the mouse reel, and do so continuously if I hold the key continuously. I need it to work even if other keys are being pressed at the same time, and only work on a certain window title/tab title in the browser.
I basically want to emulate the function of the autohotkey program for the "Attack On Titan Tribute Game"'s reeling function.
An AutoHotKey equivalent is available at:
http://fenglee.com/forum/viewtopic.php?f=2&t=7548
(Which may be offline due to unknown reasons, might have to wait)
Basically, if you download the application, set Reel In to the "x" or "e" key, it works regardless if other keys are being held. Just make sure you uncheck the checkbox so it can work in any window. It basically scrolls down for you. It also includes the source.
Or.. if I can use any other free application to do the same thing, that'd be nice.
All I want is the scrolling function and it has to be specific to a window/plugin/etc. and be able to be triggered while holding down other keys.
I am making application using silverlight.Here i want to move line on screen continuously on left and right arrow key pressed. In silverlight application there is facility of RepeatButton but i am not getting how to use it. Please help me if there is any solution on that.Thanks in advance.
An easier method would be to have (bool) flags like "keyLeftPressed" and "keyRightPressed". Then, on a specific tick (from a DispatchTimer possibly), check if the flags are set and take appropriate action. Finally, use four events to set the condition of the two flags: left key pressed, left key released, right key pressed, right key released.
I created a custom item in which I need to use the Center Key for the purpose of selecting and I am successfully able to use it with the keyPressed event using the keyCode as -5. The problem is, as soon as I press the CK, it also clicks on the command above the LSK and that causes the menu to pop up. Is there any way that I can disable the CK for a particular command or something like that (because I dont need CK, since I can click on the command through LSK as well, I want to use the CK specifically for the custom item) ?
If the CK key is by the phone platform definition does something then as far as I know there is nothing you can do, this is platform default. which device do you try this on?
