TextBox TextChanged event not triggered

Posted By:      Posted Date: October 02, 2010    Points: 0   Category :WPF

I have a textbox, under a specific circumstance, its textchanged event doesn't fired.

the keydown and previewkeydown do fired.

I assume there are other control intercept the keydown event and fool around it, probably did something over it.

but what can caused the textchanged event being cut off?

or any debugging approach for this?

i tried the AddHandler to the textchanged, in case its handled prop set to true that caused the cut off. but same, the event still don't get triggered under that special circumstance.

Composite control: How to bubble a textbox's TextChanged event?


I've created a composite control that contains several controls, including a textbox. I'm trying to expose the TextChanged event of the textbox as an event on the composite control. I understand that events can be bubbled up the control hierarchy and handled at a higher level, which I've attempted to do, but I can't get the bubbled event to fire. When I drop the control on an aspx I can see the TextChanged event, I can subscribe to the event, but nothing ever happens. Any suggestions? Here is what I think is the relevant code:

// My event
private static readonly object EventTextChanged = new object();

//Handle the bubbled event
EventHandler textChangedHandler = (EventHandler)Events[EventTextChanged];

protected override bool OnBubbleEvent(object source, EventArgs e) 
    bool handled = false;

asp:textbox TextChanged event


I have a textbox in my app in which I have code behind in the "onTextChanged" event that I'd like to execute  without doing an entire page post back . 

I can't use use AJAX not an option for me (corporate thing). 

Anyways, I have been struggling with the specifics on implementing ICallbackEventHandler. Or is than another way I can/should do this.

The code in the textChanged event pulls a dataset from the DB and does a validation.

Any advice is appreciated.





TextBox in UserControl: "TextChanged" event does not see other controls


I am building a UserControl with several TextBox controls. The behavior I'm looking for, is everytime a value is changed in any TextBox, the UserControl refreshes a couple labels contained within it. Here's the code behind file that does the work:

Public Sub Refresh(ByVal sender As Object, ByVal e As System.Windows.Controls.TextChangedEventArgs)
    lblTotalHours.Content = txtHours.Text
End Sub

Now, here's a way to hook it up that works, however, "PreviewTextInput" gives the old textbox value to Refresh() and not the new one (as expected). I'm just writing this example because I had to confirm that my method of linking the event worked - and it does. My application runs fine even though the result isn't what I am looking for: (edit: to make it work, i also adapted the Refresh() declaration to match the PreviewTextInput delegate to TextCompositionEventArgs, if I recall correctly...)

<UserControl ...>
        <Style TargetType="x:Key TextBox">
            <EventSetter Event="PreviewTextInput" Handler="Refresh" />
        <TextBox Name=&q

DataReceived event not triggered in vb.Net until serial port is closed & opened again

I am developing an application which sends multiple AT commands to a modem in VB.Net. After writing an AT command to the modem, I see the dataReceived event is not getting triggered until I close the port & open it again & write the next AT command. This behavior is consistent. As soon as I write the next AT command the response of previous AT command is read. Even adding a delay between the two write operations does not work. I also added a readData between the two writes so that data is read if it exist in buffer or stream but is not triggering datareceived event because bytestoread is non-zero, but that does not hep too. Because of insufficient read operations the data in readbuffer grows(accumulating) & after sometime the modem stops receiving the AT commands. Please suggest a solution code for data received handler & read data function   While comPort.BytesToRead > 0     Dim msgCharArray(255) As Char       If comPort.BytesToRead >= 256 Then     comPort.Read(msgCharArray, 0, 256)   Else    comPort.Read(msgCharArray, 0, comPort.BytesToRead)   End If   End While

AjaxControlToolkit TextBoxWatermarkExtender fires TextChanged Event on every postback


I haven't been able to find anything on the net about this yet. A project that used to work fine all of a sudden started having trouble with a couple users. The TextBoxWatermarkExtenders for these users are now always firing the TextChanged event of the textboxes they are assigned to for every postback. I don't think this is what they are supposed to do. They didn't use to do this. Has anyone else experienced this? I can add code to ignore these unintentional events, but I would like to know why all of a sudden the change in behavior.

Any information about this would be greatly appreciated.


TextBox AutoPostBack not working when handling other DHTML event


I have to format a number in a TextBox while it is being typed. Right after the TextBox looses focus, I need to do other processing on server side, including some database queries.

I'm doing the formatting by handling the onkeyup event, client side. But when I add the handler, the onTextChanged event stops firing on the server. I've tried different return values for the handler but unfortunatelly I'm stuck.

To reproduce the problem, here is a sample where the formatting function was replaced by a simple "convert to uppercase" function. You'll see that, contrary to the expected, the Label doesn't get filled when the TextBox looses focus. It does get filled, however, if the user presses the ENTER key.

What can I possibly be doing wrong with such a simple task?
