TextBox TextChanged property in Windows phone - windows-phone

I read this article about TextChanged property in Windows phone:
http://msdn.microsoft.com/en-us/library/ms742880(v=vs.110).aspx
I want to know if there is a property for TextBox so that I get notified when user put focus to that TextBox and then get notified when user clicks something else on screen to make the TextBox lost focus?
Basically, I have a multiple lines TextBox, which accept 'Enter'.
So I want to get notified when User changes the Text after he leaves the Text Box (not get notified every key the user enters in the TextBox).
Thank you.

There are GotFocus and LostFocus events on TextBox you looking for

VB.NET ComboBox Not Recognising Text Change

I have an application whereby I have the behaviour of 2 groupboxes enable/disable based on the value in a combobox.
This combobox however the behaviour for the group boxes only works when I leave the field by tab or click, not when the text changes.
I have tried using the Leave, TextChanged, Validated Events and everytime I have to actually "Leave" the field for it to perform the enabled/disabled of the groupboxes and their subsequent controls.
I need it so that when they choose 1 of the 3 options it immediately changes and doesn't work when they leave the field but when they choose the correct word.
Any assistance would be great I'm tearing my hair out here.
I think you are looking for the event on your combo boxes
SelectedIndexChanged
To stop the user from leaving an invalid field use the event
Validating
set the e.cancel to True if the validation fails

Show on-screen keyboard when textbox clicked

I've built a on-screen keyboard for a surveillance system made in VBA. I need it so that when the user clicks on the textbox to enter the data, the on-screen keyboard I've made, shows up. Thanks!
Check out the _Enter() event that fires when a user clicks inside the textbox control.
Private Sub TextBox1_Enter()
frmKeyboard.Show
End Sub
For a more complete solution, you may want to wrap the keyboard showing/hiding events in a VBA class so you can more easily apply it to the different text boxes on your form. That way you don't have to repeat all of your code for each text box on your form. Just something to explore for down the road. :-)

How to make text box accept Return key function (used for Browser)

I want to know how to make my Text box (or Address bar) accept the Return/Enter key as a form of submitting a search.
Currently I have a button which submits the search, and not the textbox itself.
Thanks.

textbox itself.
Assuming WinForms, set the AcceptButton property of your Form to that Button. Now when you hit enter the button will be automatically clicked for you:
Gets or sets the button on the form that is clicked when the user
presses the ENTER key.

What is another alternative to `TextChanged` event

I am working in windows form and have a few textboxes on a form.
These textboxes from top to bottom are connected, so if the text changes in textbox1, then txtbox2 and txtbox3 have to comply, if something changes in textbox2 then 3 has to comply;... and so on ... not going to bore you.
Now I was looking for an alternative, more efficient way of calling the textchanged event on the textboxes so it doesn't do everything everytime, even if one charater has changed....
Something like focus off textbox event ... or some other alternative .
This would be in vb.net and windows form.
You can use the TextBox.LostFocus event inherited from Control.LostFocus.
This event is fired when the control looses focus, like Tab or clicked on another control.
TextBox1.LostFocus perhaps? Or enable validation on the controls.
Control focus event order:

textchanged event of textbox in vb.net

I want to fire the textchanged event of textbox after the user enters text/data in the textbox in vb.net. But the event is getting fired as soon as the user enters the first word in the textbox.
is there any way I can solve this problem? I tried googling but didnt get satisfactory solution..
TextChanged Event is triggered when there is any change in the TextBox.
If you want to invoke something after user finishes up then try using LostFocus Event of the TextBox which will be triggered as user leaves the focus from textbox.
