Detect keycode ALT+L via Javascript -


I want to find out that a user presses F12 or ALT + L. 

  Documents. Onkeydown = function (event) {event = (event || window.event); If (event.keyCode == 123 || (event.keyCode == 18 and event.keyCode == 76)) {// anything wrong lies; }}

What am I doing?

The standard way to indicate that 'alt' key is currently placed below and then To find out if it is true and if the L key is pressed - look at Bela:

var holds = false; ... and if (event.keyCode == 18) {organized = true;} if (organized == true & amp; event.keyCode == 76) {warnings}; } ... document.onkeyup = function (event) {if (event.keyCode == 18) {held = false;}}

To keep any combination of this key Applicable - You can create an array for multiple keys to hold more than two: 

  organized = []; ... if (event.keyCode == i) {organized] [i] = true;} ...

and so on

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment.
