I have added a Canvas to the Grid then added my custom keypad on the canvas. Now on TextBox.GotFoucs event I changed Canvas.Visibilty = Visiblity.Visible;
But the issue is that when the TextBox gets focus it shows the default keypad in front and my Canvas behind it. I want the Canvas to be displayed on top of the default keypad and should work as a text entry control to the TextBox. How can I do this?
The display of the SIP is handled by the operating system and will always be on top of the visual tree of any application. If you want to provide a custom SIP, you will need to provide an alternative input control, because the display of the native SIP is tied to input controls (such as TextBox, PasswordBox, etc.).

I have a grid, and when the user swipe it, a textbox will reveal and the keyboard will show.
The function is ok, but there is a little bug, when the system keyboard show, it will cover over the textbox, so the user can't see the stuff they have entered.
how to solve it?
It would be best to position such a textbox so that it would not be obscured when the keyboard is shown. This is typically done by placing it at (or near) the top of the page.
Depending on how you've structured your XAML the default behaviour of the phone should scroll the content so that it is not obscured by the keyboard. Without being able to see you code I couldn't say why this isn't happening.
Alternatively you could but the page content inside a ScrollViewer and manually scroll it so that the TextBox is visible when it has focus.
I have a WPF datagrid (4.0) with a custom column (derived from DataGridTextColumn).
In GenerateEditingElement I create a custom textbox control (with an additional button) and like to set the cursor into it so that the user can directly start editing.
The closest I get is that the caret is shown but is not blinking and I need an additional click to start editing.
All other stuff (binding, ...) is working nicely
Any ideas?
Since the caret is shown, but not blinking, then I am guessing your control has Logical Focus, but not Keyboard Focus.
How are you setting the control as Focused?
myControl.Focus(); will give the control logical focus, but it won't respond to keyboard events because it doesn't have Keyboard focus. To give an element KeyboardFocus, use
Keyboard.Focus(myControl);
This is because WPF allows you to define multiple Focus Scopes, and each scope can have it's own focused element, however only one control in the entire application can have Keyboard Focus
I want to add the menubar to TextBox control in Silverlight 4. (I will create a new reusable control.) The menubar will consists of a few image buttons. The idea is that it will normally stay hidden and will show up only when the user puts his/her mouse cursor to the TextBox area. If used in a multiline textbox, whole menubar can fit inside it, this should be easy. (I hope. :-))
But how to solve situation when TextBox is in single line mode? I'd like to put the menubar above the TextBox. But I don't have a clue how to do it. Can somebody help? I need to let all other controls in a form to stay in their positions, and only add my menubar above my textbox. (So the menubar will NOT hide the textbox. Instead, it will hide other controls residing right above the textbox.) It should work in all arrangements of form, like Grid, StackPanel, Canvas etc. In the fact it would be similar to a classic right-click context menu, but not modal. (Right-click context menu is modal, i.e. while it is shown you cannot use other controls, and it automatically hides when you click anywhere else. I want my menubar to stay visible as long as user heeps mouse cursor over the textbox or the menubar.)
Example: Coordinates of textbox are top=100,left=20,bottom=115,right=120. So my menubar's coordinates should be bottom=100,left=20, right & top are based on size of menubar.
If many textboxes will be used on a single page, each single one should have its own menubar. (Of course.)
You can create your own control (custom control or UserControl, whichever you like should work) which has the TextBox, and the visual for the menu bar.
If the TextBox is single-line, you could display the menu bar in a Popup which you position just above the TextBox whenever the mouse is over it.
If the TextBox is multi-line, you'd simply use a StackPanel or Grid or whatever to do layout like normal, if I am understanding what you want.
No coding required if you use this menu:

To achieve this behavior you will need to set its IsPinned property to true.
I have an ActiveX control inside a WinForms user control. My WinForms app loves it!
Now, moving over to WPF, I use the user control in a WindowsFormsHost control. Works great..., but I want to treat this control as a single element so the user can neatly hit TAB over the existing WPF controls AND this user control NOT to 'go inside' it. i.e. just treat it as a single control like all the others.
I think what i need is the ability to trap the keys, and in the event handler simply move focus to the next control in the sequence, but I can't seem to trap any keyboard input. Ive tried the WPF PreviewKey.. events and the like, but once the tabbing gets to the control, it seems to stay inside it and WPF events are ignored.
I couldnt find anything on this in many WPF books and the net. Can anyone suggest a way ?
Thanks,
Jack.
Can't you create some sort of a filter by doing a preview mouse down on the panel or window (whatever is the parent of your controls), this way the panel will catch it before the user control and you should set e.handled to true, and if the user control raised the tab event, keep pushing the focus until you get another control. Preview and e.Handled=ture should solve the problem.
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.
