Hello,
Glad you got it working. Unlike in ASP.NET Webform TextBox controls, we can't directly use AutoPostBack features in mobile TextBoxes to cause a postback to the
server when you change text in the textBox. This is because some devices/browsers do not support javascript which the webform autopostback
makes use of. Thus in order to cause a postback to the server so that your code executes, you will need to explicitly user the command button the way that you are
currently using.
Thanks.

| GOT IT.........
|
| Looks like I was trying to do too much on one screen. The
| coment I made in the last post 'Its almost as if the
| phone isn't quite sure where the Find button is located'
| seems quite true.
|
| Originally I had
|
| TEXTBOX
| COMMAND
| LIST
|
| all on one form, as soon as I moved the list into a form
| of its own, the command button works a treat, it isn't
| displayed anywhere except as the softkey. (Previously it
| was showing as a softkey on one page and <FIND> on the
| subsequent page. I'm still finding that textboxes either
| dont instantiate a proper postback or the contents are
| not accesible on the postback hence why I still have to
| resort to a command button. By Design?
|
| Does anyone happen to know where I can find a good
| Motorola emulator as this project is costing loads in
| mobile pay as you go airtime. I have checked the ones
| detailed on the ASP.NET site but they seem more like
| advanced PDA type emulators not just for basic phones.
|
| Thanks Pete.
