I am doing a WPF application with a virtual keyboard .As mentionned in the picture, there is two textbox pseudo and password and i'd like to enter their values using the virtual keyboard. The problem is how to know that the cursor is in the first field or in the second one or out. Not the answer you're looking for?Browse other questions tagged c# wpf xaml keyboard or ask your own question. This was a fun project done to do in Windows Presentation Foundation (WPF), and I thought it’d provide a useful article to youz because of the range of design techniques it uses.
It’s an auxillary WPF window which, if you integrate it into your application, allows you to provide a way for your user to invoke it and click on the key-buttons to insert characters into your application text fields. As a further aid in typing, along the bottom edge, are thirteen extra typographic symbols you can type. As a further convenience, just for kicks n giggles – when you move your application around on the screen, this keyboard Window can move in sync with it. When you click on the SHIFT LOCK key, you have access to the shifted-state key symbols that you see on the keycaps, in addition to capital letters.
The easiest way to tell how to use the VK in your own design, is to show you a simple demo-app that does just that. The two buttons have click-handlers which serve to launch the virtual keyboard, and to close the application.
I use a certain coding formatting standard in all our projects, which I’ve detailed here.
As you can see on line 5, it remembers whether the VK was up when we last ran this application.


If you have just one text field, you would simply return that (the instance-variable for the field).
If you handle the LocationChanged event of your Window thus, then the VK will move around along with your Window, like it’s stuck to it. This demo-app has two text fields so that you can see how to use your VK to serve input into more than one control.
I’m quite fond of object-oriented design, especially where it saves time and yields a more elegant creation. To forge this scheme into our WPF XAML-based application that has fifty data-bound buttons, check it .. If you look at the KeyAssignmentSet class in Visual Studio (VS), you’ll see it has a big honkn glob of instance variables and properties. Right now, looking at this XAML in LiveWriter, the button Content shows up with the syntax for the hexadecimal 00A7 value, with the ampersand, pound, x prefix and the semicolon suffix. This Style targets all Buttons, thus it becomes the default for all Buttons within that container.
I had to tinker with and fine-tune the sizes, padding and margins to get it to look it’s best.
The most interesting thing (well, to me anyway) in this Style is making the key-buttons visually float off the surface a bit, and then seem to push downward (and to the right slightly) when you click on them, to yield that cute 3D affect. A slight complication for me was that that Text property, and the ToolTip, needed to yield different values depending upon whether the shift key was in effect. The Text property acts similarly, except that it selects from the key’s _text instance variable if that was explicitly set, otherwise it returns the unshifted or shifted codepoint that was assigned to that key. Thus, here we tell the VK to close itself, and hook into the Closed event so that another method gets called after the VK closes. A bit of usability testing revealed that your users, in attempting to enter their stuff using the mouse, preferred a shift-key that would reset itself.
Note that everytime your user clicks on anything within the VK, the VK’s Window gets focus. The WPF virtual keyboard input system is an essential feature ensuring seamless user experience.
It works just like the standard Windows WPF keyboard, where the users input text pressing corresponding keys on a touch screen. Languages are included in the package and can be loaded by the FPS Keyboard Creator or directly within the WPF on-screen keyboard control. Now it can be done by FPS Keyboard Creator tool that is supplied with any license of this product.
It now includes most of the world’s languages and dialects being added into Windows operating systems.
The acquisition allows MindFusion to widen its sets of WinForms and WPF programming components, which are used by developers worldwide to create smart and user-friendly applications. Some API changes have been made to the component in its first release by MindFusion - you can read them at the components documentation available online.
The Virtual Keyboard components are offered both as stand alone products and as part of respectively MindFusion WinForms and WPF Control Packs.
You'll need to keep a reference to the last focused text box, and then use the keyboard button click events to add a single character to one other input fields. You can provide a way for your users to enter characters that they don’t have on their physical keyboard. WPF yielded a few side-bennies like the fact that you can resize this Window and all the keys resize themselves appropriately. My immediate need was for a memorization flash-card program to learn various language terms as in Arabic or Russian, so that’s what I created first.
The demo app that comes with your download is a pared-down WPF application that has a simple TextBox to receive the characters, and a Button for launching the virtual keyboard.
The DockPanel on line 1 is there simply as a convenience for sticking the buttons along the bottom. To achieve this, you simply add a boolean flag to your settings; in this case we named it IsVKUp. This is placed here, within the ContentRendered handler, because at this point your Window is already rendered and the VK can know where to position itself. Thus, you’ll still see the nice blinking caret in your text field, just as you would without the VK.
And, considering the central role of the common US-std English-language keyboard, I based the root class of the hierarchy of keyboard layouts upon the English US keyboard to supply the default properties.
All the key-buttons use this same KeyPressedCommand, with the command parameter carrying the character to inject.


But at the same time, the published version I’m looking at online in FireFox, shows the actual signum sectionis instead. As you can see from reading the XAML, the trigger fires when the IsPressed property becomes true. As you can see, the Content of these Buttons is set to the Text property of the VK_1, VK_2, etc. So, clicking on either of the shift keys pushes the VK into the shifted state, and then clicking on any character pops it back into the un-shifted state. A common example of a touch screen virtual keyboard app is the automated checkout terminal. WPF keyboard software can be used in a variety of applications for touch screen interfaces to improve user experience. MindFusion shall provide full technical support for all FreezePro clients through its discussion board, help desk or per email. It also has French, German, and Spanish, which only actually add a few locale-specific characters. But you can put those to use for something like the dead-letter keys that certain keyboards use languages. I’ve been in the habit of throwing the DockPanel in there everytime I create a new Window.
You give it a reference to your local _virtualKeyboard instance variable, so you have a reference to it. So we instead track which one has focus using this instance-variable, and return that in this property getter.
Normally, I include a checkbox in my app’s Options dialog to give the user the ability to turn this on or off.
This variable has to always be pointing to whichever field is currently holding the focus within your Window. So if we can let the Spanish keyboard inherit all the English keyboard features, it only has to override just those keys (and their tooltips, etc.) that it wants to change. Most of the formatting is set in a Style, but this one overrides the Margin, Width and Height to fine-tune the appearance.
Navigation through such applications is performed with the use of virtual on-screen keyboards.
Perhaps you can tackle implementing a Mandarin keyboard and send to me to be included – I’d love to see!
Whichever text field has the current focus, that’s the one who receives whatever is typed into the VK. I added a 2nd text control, a RichTextBox, to illustrate using the VK for multiple input fields. Each of those keybuttons implement INotifyPropertyChanged to keep the GUI apprised of their values when they change. And for writing letters or posts to readers in other languages, it can be a huge timesaver. When VS 2010 on Windows x64 suddenly seems to not be recognizing certain of your projects, check the build configuration. And then to boil it down to it’s essentials to the smaller application you see before you. That arrangement should be chosen (by my reasoning) to most resemble what a native speaker would most likely be used to, within the confines of the standard keyboard layout. In some cases I’ve had to use a negative bottom-margin to get it to nudge as near as I wanted. I’m sharing this with you, to save you time on your projects and to illustrate techniques.
Tried that same method with a girl at the theatre, but that didn’t have positive results. Please be gracious in your feedback and contribute your own improvements so we can evolve this with improvements. If you send me your suggestions, I’ll edit them into the code upon the next revision and cite you as the contributor.
