OnTextChanged Event for a label control

Sue
Hello

Is there an equivalent of a OnTextChangedEv ent for a asp: label
control in asp.Net 2.0. Every time the text of a label changes, I want
the items in a listbox control cleared.

TIA
Sue..

Since ASP.NET controls are rendered to the client as HTML (in this case, a
<SPANtag), you need to be thinking about what client-side event would work
for you, the server-side events are only triggered if a postback is
initiated. So, you should add this to your asp:label control via the
page_load() event handler:

lblSomething.at tributes.add("o nChange","clien tSideFunction() ")

And then add a client-side function that matches the second parameter you
gave above that does the clearing of the listbox data.

Hi. I have created a web-based file manager. Now I'd like to watch a folder for changes, and when a change occurs I'd like to refresh my page. Okay. So I have created a FileSystemWatcher set on the folder I need to watch. It works fine. The problem occurs when I need to trigger an automatic Refresh. So I added two handlers - OnChanged and OnRename, in the same class as my filemanager.

I think I already know the answer to this but here goes. I've read the other postings but no solutions for this. If a user enters a textbox, there is no 'onenter', etc. to control firing off a sub, etc. We have OnTextChanged. But it doesn't fire until focus is placed somewhere else. The issue is that on my form if a user changes a textbox but goes to 'Save' the form, the 'Save' button gets the focus and fires event OnTextChanged but stops...

I've got a form that is supposed to validate data entry from a bar code scanner. The scanner is set up to add a carriage return at the end of the data in the barcode, which should fire the onTextChanged event to validate the information recieved; however, the Enter key does not fire this event as it should. Can anyone give me some help as to why the Enter key won't fire the onTextChanged event? Matt

Tried doing as textbox and gave the ReadOnly="True" and border=0 to mimic a label control, but since the Readonly is set to true, the "OnTextChanged" event does not get fired.
