keydown

I'm using WinForms. I've created an event handler for the KeyDown event of the main form, thereby invoking a button's Click event handler. The Click event handler called is dependent upon the specific key pressed. If a user clicks the button rather than using the key, and then subsequently tries to use the key thereafter, the key (down arrow for example) acts as a tab-cycle, changing focus between each button control on the form (rather than executing the Keydown handler). Any ideas ? The problem is, the button has the focus when it is clicked, so subsequent key presses are not caught by the

I have a webform and i want to detect if F5 button was pressed or if the page was refreshed. I know about postback but it is not what i'm looking for. I have a gridview that loads in a modal popup when a button is clicked and a parameter's value is set for the gridview. When refresh is hit and if the modal popup button was previously clicked the modal popup is visible right after refresh. I want to detect if the page is refreshed to prevent this. any ideas? I thought to try Override but I'm not exactly sure how to use it. I tried Control.ModifierKeys but I don't have access to ModifierKeys.

How can I determine in KeyDown that ⇧ + Tab was pressed. private void DateTimePicker_BirthDate_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Tab && e.Modifiers == Keys.Shift) { //do stuff } } can't work, because never both keys are pressed exactly in the same second. You always to at first the Shift and then the other one.. It can't work, because never both keys are pressed exactly in the same second. You're right that your code doesn't work, but your reason is wrong. The problem is that the Tab key has a special meaning - it causes the focus to change. Your event handler is

I've got a simple javascript keydown event coded via jquery. The event should just alert the key that is "down." This works for most keys but not the backspace key in Internet Explorer. I read that IE messes this up on the keypress event but was supposed to work for the keydown and keyup events. Is there anything I can do via jquery to capture the backspace in IE? The version of IE I'm currently testing in is: 8.0.7600.16385 $('.AddressField').bind("keydown", function (e) { alert(e.keyCode); }); use which: $('.AddressField').keypress(function(e){ alert(e.which); }); keyCode property is not

I'm trying to find a way to validate a text input on key press, I want to allow numbers only inside my text input including decimals. I was taking the approach of using jQuery.keydown, and checking what the key was and using event.preventDefault() if the key was not in the allowed list. But since then I've read that keys aren't consistent throughout browsers and I'm also worries about different OS's. I've come across this question but I'm not fluent in regex and not sure whether this would suit my needs: jquery - validate characters on keypress? With that approach a regex that expects 00.00

I'm building a terminal emulation and running into an issue with capturing backspace in Firefox. I'm able to nab the first backspace and remove the last character on the input at the prompt, but it won't persist and remove more than one character.
