default button stops working

I am working on a web form for my client's portal. This form utilizes a user control (also written by me) that will, when needed, display a panel (which also makes use of the ModalPopupExtender) for user interaction. After I have shown then hidden said panel, the form's "submit" button no longer fires its click event when the Enter key is pressed. The panel itself contains a couple of UpdatePanels in order to do some Ajax functionality, if that helps flesh out the whole picture.

Does anyone have any suggestions on how I can ensure that when the User Control hides the aforementioned panel the default button action is fired when the Enter key is pressed? I would prefer it to be part of the User Control's code so that users of the control do not have to remember to do an extra step.

You say "stops working", not "not working". When it was working and when was not. How about some code samples for both cases?

Sergey,

There are too many layers of inheritence in my client's framework to be able to give you a representive sample. Suffice it to say that prior to showing/hiding the panel, if I press the Enter key the "submit" button's clicked action is fired. After showing/hiding the panel, one has to click the button with the mouse, the action is not triggered by pressing the Enter key.

Well, then I would classify it as "not enough information". Don't you see it's not enough?

Solution 1

I would say, when you hide the panel add one more line of code which would set focus on one of the control of user control which would let the browser know where is the focus now to fire default button when pressing enter.

Hope this helps.

Solution 2

Try to set the defaultButton property of the panel.

<asp:Panel DefaultButton="MyBUttonId" />
