In WinRT, is there a way to be notified when the text of a TextBlock changes?
I don't see a TextChanged event.
TextBlocks aren't editable (read-only). So, there's not a TextChanged event like there is for a TextBox. If you need to know when the text has changed, you'll need to wire up a listener to the source of data (maybe through PropertyChanged for example).

In my form contains textbox and button. I am doing some operation in textbox (blur) event and button (click) event.
Let's assume:
user enter some text in textbox and click the button. (blur) event invoked but (click) event not invoking.
note : "at the time of clicking the button focus should be in textbox."
example: https://stackblitz.com/edit/angular-b4h9pi
blur event alert is coming but click event alert not coming.
Scenario
In onblur event I make the service call to save that field value. In onClick event I have to save all the fields data. If cursor focus one of the textbox then user click the save button. First I have save the field after finishing the first call, make the second call to save all the data. Do not call the service parallel. I want to call one by one.
Remove alert with console.log or other relevant code. alert will be triggered as as soon as focus is lost from the input even before the button is clicked. So two event is not firing simultaneously
stackblitz
Both events are indeed firing. You can confirm by changing your alert calls to console.log. I believe the browser is likely just blocking multiple alert dialogs.
Update to answer your comment:
You say you want them to fire simultaneously and then you say you don’t so I’m having trouble understanding your needs.
I can tell you this though. The blur event fires, then the click event fires. You should be able to handle whatever you need to in those handlers with that knowledge.
If you need to wait for your blur handler to come back with a response before sending that data along with your click handler, you could theoretically set a variable like
this.blurRequestLoading=true
That way, instead of firing the click request, if blurRequestLoading is true, you could set a this.clickEventPendingBlurResponse=true.
Then when the blurResponse comes back, you can set blurRequestLoading back to false, and if clickEventPendingBlurResponse is true, fire the clickEvent manually within the response handler, and set clickEventPendingBlurResponse back to false.
Hi thanks for your time and effort, i did one logic to sequence the event, please suggest me is this code in production level.

I am using DateField as editable one in my application. And I did change event for filter function. Now I want to do the same function for each keystroke. I tried ValueCommit. But it's did nothing. My questions are:
Is there an event one can use when someone changes the actual value in a DateField's TextInput control?
How to use this textinput as a normal TextField component?
Thank you.
You can use keyUp event. It will be rised every time when you release pressed button in the TextField. I think this will make the trick.
<mx:DateField keyUp="datefield1_keyUpHandler(event)" editable="true"/>
This is my first post and is probably really dumb.
I have a single-frame actionscript-3 fla file. When my movie clip is clicked, it fills in a dynamic text field with randomly generated text. (Basically, it's an insult button.) It only works the first time, though. How do I make it refresh the text on each click?
If the TextField is generated programmatically you should try re-applying the TextFormat. I find I have to do this for AS generated TextFields when I update the text.
I'm working on an application in Flex 3.2, and I need to be able to tell whether the current focus is a textbox or not. How would I go about doing this? There's more than one textbox in my application, so I can't really set multiple event handlers for focusOut, etc.
Thanks,
Matt
You can accomplish this by using the stage.focus property. It holds the instance of whatever object has the focus.
So in whatever spot you want to do the check, just do this:
if(stage.focus is TextField){
//do whatever you'd like to do
}
I'm not really a flex user, but I'm pretty sure the text components use TextFields inside them and that the focus will still be a TextField class. Someone please correct me if I'm mistaken.
I am using a editable datagrid and want to autosave the edited information in an editable column. Also, since its a simple text editing I don't want to use itemEditor/Component for the same. I was hoping to have a focusOut event but I dont see any focusOut event for datagrid column(even if its editable?). What event should I be using?
Thanks.
I got it working by using itemRenderer in which I used a text box and handled it with textbox's focusOut property. Still wondering how could I have done it directly from dataGrid's event.
