OnTextChanged and DataGridItems

Hi,

I currently have a datagrid with template columns containing textboxes etc.
The textboxes are in the item template so the whole grid is editable by
default, I then have a general update button to update the whole grid. I'm
using the example under
http://msdn.microsoft.com/library/de...verControl.asp

I'm using the OnTextChanged event to capture which rows have been changed by
the user. Inside of this event I want to update the datasource of the
datagrid with the new values, my problem is that I can't seem to access the
new values. At this point everything is empty. I'm using
DataGridItem.Ce lls[0].Text etc to get the values, I can see that the grid has
the correct number of cells using the count but the values are all ""... any
ideas?

because your using a textbox event and not a datagrid event you dont
now from which row to get the new data?

you could try accessing the value from sender withing the textbox event

ctype(sender, textbox).text

but now you will need to know which row to save it into?

personally i wouldnt use OnTextChanged to save because it will cause
alot of server overhead.

coz it will do a server postback on each keypress wont it?

Oops! Made a silly mistake, I've fixed this now.

I need to look at the controls collection within the cells to access the
textboxes!

thanks

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

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
