addclass - JQuery swapping classes -


I am learning JQuery and when I write my own small scripts, then there has been a problem. So I have a navigation bar and every time a button is pressed, it should change its CSS class from 'BTN' to 'ActiveButton'. For testing purposes, I just want to be able to click on that button, and switch it back, though it does not. Does JQuery not update classes right now? If so, how do I force JQuery to do this? 

  & lt; Div class = "btn" & gt; Hello & lt; / Div & gt; & Lt; Div class = "btn" & gt; World & lt; / Div & gt; & Lt; Script & gt; $ (".btn") .click (function () {$ (this) .removeClass ('btn'); $ (this) .addClass ('activebtn');}); $ (".activebtn") .click (function () {$ (this) .removeClass ('activebtn'); $ (this) .addClass ('btn');}); & Lt; / Script & gt;

Just be able to do this: 

  $ (".btn"). Click (function () {$ (this) .toggleClass ('btn activebtn');});

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. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
