How do I select the entire text when the focus is moved to one TextBox?

How do I select the entire text when the focus is moved to one TextBox?
There are three TextBoxes.  I use <TextBox TabIndex="1"/> to set the order they are selected.  When I enter one specific TextBox, I would like to have the entire text selected ... one key stroke removes all of the text in that TextBox.

I do it the following way:
1.  Override the OnStartup for the application.  Use the following code: (VB.NET)
EventManager.RegisterClassHandler(GetType(TextBox), TextBox.GotFocusEvent, New RoutedEventHandler(AddressOf TextBox_GotFocus))
2.  In the event handler use this code (again VB.NET)
Private Sub TextBox_GotFocus(ByVal sender As Object, ByVal e As RoutedEventArgs)
_theTextBox = CType(sender, TextBox)
If setFocusTimer IsNot Nothing Then
RemoveHandler setFocusTimer.Tick, AddressOf setFocusTimer_Tick
End If
setFocusTimer = New DispatcherTimer
setFocusTimer.Interval = TimeSpan.FromMilliseconds(10)
AddHandler setFocusTimer.Tick, AddressOf setFocusTimer_Tick
setFocusTimer.Start()
End Sub
Private Sub setFocusTimer_Tick(ByVal sender As Object, ByVal e As System.EventArgs)
setFocusTimer.Stop()
_theTextBox.SelectAll()
End Sub
What this does is register a handler for every textbox in your application.  This will execute when the GotFocus event is raised and will allow you to do whatever (in this case select all) you want.  A great way of handling things at the application
level.

  • How do I select similarly colored text using the magic wand?

    I converted a large document from RGB to CYMK (File | Document Color Mode). I'd like to select all of the text that was RGB(0,0,0) and is now CMYK(75.02,67.97,67.02,90.16) so I can change it to CMYK(0,0,0,100). I think the magic wand is the way to do this (correct me if I'm wrong).
    I have text in a dozen or more text areas. Many of the text areas overflow text into another text area. Some of the text in the text areas is "black" but there is also text with other colors that I'd like to remain unchanged.
    For example, I'd like to select all of the black text in the following two text areas without selecting the red text. I thought  that I could click on the black text and have all the black text (but not the red text), selected, but the entire text box is selected (and nothing in the second text box is selected). Can the wand select some text within several text boxes? If not, how should I go about changing the black? Thanks.

    Thanks Mylenium.
    If I use the Same Fill command, it does select both text areas. But if I then choose a replacement color (e.g., CMYK(0,0,0,100)) all of the text in both text areas is changed to black (i.e., the red text in my above illustration also changes to black).

  • Highlight the bookmarked text when clicking bookmark link?

    I have severeal bookmarks on one page of the PDF. Is it possible to have the PDF set up so that it will highlight the bookmarked text when the bookmark link is clicked? Or something that would make it easier to find the bookmarked section of the document. I am using Acrobat 9. Thanks!

    A bookmark (go to page view type action) doesn't really link to text, it links to a page and view setting (zoom, and possibly scroll). So this isn't an option with such a link.

  • On ios7, How do I only have a contact's name popup when they text me rather than the entire text?

    I just bought the iPhone 5s and am having trouble setting up the messaging as I had it on my iPhone 4s. When I receive an imessage or text message, I prefer that only the contact's name shows up on my lock screen. Right now, the contact's name and the entire text pops up on my lock screen. How do I fix this?
    I went into General Settings and then Messages, and have played around to try and fix it, but haven't had any luck.
    Any advice?
    Thanks!

    HI, I recently upgraded my operating system IOS 5.0.1 on an iphone 3gs. My question is, how do I get the text messaging preview to just pop up so that I can see the name only when the lock screen is on? The conventional ways of doing this, such as using turning off the SMS preview under the "passcode lock", well that option no longer exists, or if it does, I'm somehow missing it.
    When I go to the "messages" setting under settings on my phone, I still don't see an option of turning it off.
    If I can just get the name of the person sending the message, as I had it before, I'd be happy.
    Help!

    That option still exists in Settings > Notifications > Messages > Show Prview (OFF) and View in Lock Screen (ON). Here's how to configure your Notifications and Notification Center for iOS 5: http://iphone-and-i.blogspot.com/2012/01/how-to-customize-notification-center-in .html

    This is probably one of the files that is required by the template you are using.
    These files are inside the iWeb app. Control click the iWeb app icon and select "Show package contents".
    You need to dig down through the folders and files to find what you want...

    If the file is missing you would need to re install the iWeb app...

  • Newbie Mac user:  Selecting block of text via the keyboard only?

    Hi,
    I'm switching over to a Mac from a PC and haven't been able to find an answer to this question. How do I select a block of text only by using the keyboard?
    As an example, on the PC from wherever the cursor is in a document, if I then hit Ctrl-Shift-end, the entire rest of the document from the cursor down is selected. Another similar task would be to select all of the text from the cursor to the end of the line, which on the PC can be done with Shift-end.
    Are there Mac equivalents?
    Thanks.
    Les
    MacBook Pro Mac OS X (10.4.10)
    MacBook Pro   Mac OS X (10.4.9)  

    COMMAND-SHIFT-end to select from the cursor to the end of the line. COMMAND-SHIFT-pagedown selects from cursor to end of document, use pageup to select entire document.
    Other alternatives:
    Press SHIFT and use the right arrow key to select characters. Use OPTION-SHIFT and right arrow to select words. COMMAND-right arrow key moves cursor to end of line and OPTION-right arrow moves cursor to next word.
    See also: Mac OS X Keyboard Shortcuts.
    In many instances wherever Windows uses CTRL in a shortcut the Mac uses COMMAND (Apple Key - ⌘)

    Both Chrome and Finder seemed to freeze, so I restarted the computer. When the restart finished, I was in recovery mode. How do I get back to my regular login screen?
    It starts up and asks for a language. After English, it goes to the OS X Utilities screen. I have gone to disk utility and verified the disks. They both say they are okay. If I click repair, it comes back with an error saying "Live file system repair is not supported." I just want my computer back to normal! Please help! I am still in Mavericks if it matters.

    Do you have a backup? If so, in the Recovery Partition go to Disk Utility/Erase, select Mac OS Extended (Journaled), click Option GUID, and erase the disk. Then re-install the OS. Reboot and use Setup Assistant to recover your data.

    Download the Windows Installer CleanUp utility from the following page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):

    To install the utility, doubleclick the msicuu2.exe file you downloaded.

    Hi sivavuyyuru,
    I cannot find a easy way to make this.
    I think you may need to draw your own Combo Box control. And you could change the edit control more like static text. Check the article:
    http://www.codeguru.com/cpp/controls/combobox/fontselectioncombos/article.php/c1795/Owner-Drawn-Font-Selection-Combobox.htm
    In the resource editor, Owner draw -> variable , Has string->true, type->drop list.
    The result:
