Hi,
I have a datagrid containing a number of item templates, inside of these
item templates I have various controls like the textbox. The user is able to
edit all the fields on the datagrid at once and then click an update button.
I'm trying to use the OnTextChanged event to capture which rows where updated
before I update the DB. I have added the line OnTextChanged=" RowChanged" to
my text box control in the HTML and added the event handler called RowChanged
to the code behind. Is there something else I need to do to make this event
work?
My understanding is that this event does not get called until the page is
posted back, so I'm hoping that when I click the update button this event
will fire for all rows that have changed and then the update event will fire,
is this correct? I'm following the example http://msdn.microsoft.com/library/de...verControl.asp
Thanks

Hi,
I've fixed this now, it seems that I must rebind the datagrid for this event
to fire. Not sure why but it works...

Hi Neil:
During binding the grid will create the textbox control. If the code
doesn't re-bind the datagrid, the grid doesn't create the textbox, and
if there is no textbox there is no object to 'fire' an event.
Hope that clarifies a bit,

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?

Help!
I have an ASP textbox where the OnTextChanged event is not firing. Here's the call:
<asp:TextBox ID="ApproverCopy" runat="server" CssClass="noShow" OnTextChanged="StoreNewTrainings" AutoPostBack="True"></asp:TextBox></TD>
The event fires if I enter the value manually, but not when I do it programmatically in the code behind.
Please help.
