OnKeyPress doesn't work for any objects inside an ASP.Net Panel with DefaultButton specified.
The problem only occur in IE 7 and not Firefox 3. Haven't tried all the other browsers.
Here's the example:
So basically, I've got a textbox that only allow the user to type numeric values, and simply ignore other key presses. To do that I use the onkeypress event of the DOM.
At the same time, I want to listen to 'enter' key as well, so at anytime the user presses enter key, the submit button is 'pressed'. To do that I simply use out of the box ASP.Net Panel DefaultButton property.
I find the solution to simply replacing onKeyPress to onKeyDown. So in the example above, I have the following:
On that note, onKeyUp wouldn't work because I want to 'filter out' the key presses, and by OnKeyUp, the character is already printed out on the DOM.
For more information about the differences between onKeyPress, onKeyUp and onKeyDown, look at the following:
