AngularJS: scope change in ngClick gets lost -


मेरे पास ngRepeat द्वारा दोहराए गए तत्व पर ngClick और ngClass है: 

  & lt; li ng -class = "{'सक्रिय': $ parent.mem.A == $ कुंजी, 'नहीं-सक्रिय': $ parent.mem.A और amp; $ parent.mem.A! = $ की}" एनजी- दोहराएँ = "($ कुंजी, ए) में" एनजी-क्लिक = "$ parent.mem.A = $ key" & gt;   
  li  के अंदर मेरे पास एक ऐसा बटन है जो  $ parent.mem.A  पर क्लिक करें: 
 
 < पूर्व>  & lt; बटन एनजी-क्लिक = "$ parent.mem.A = $ parent.findInHash ('पिछला', 'ए')" & gt; पिछला & lt; / button & gt; सक्रिय करें;

findInHash () अपेक्षित मूल्य देता है, और जब मैं कोणीय के माध्यम से कदम करता हूँ, $ दायरे में मान। $ लागू () ngEventDirective से सही है; लेकिन कहीं यह खो गया है।

आपके कोड में सभी एनजी-क्लिक हैं 

  $ scope.findInHash = function ($ event, dir, attr) जैसे कि आप नीचे दिए गए नमूने जैसे ईवेंट प्रसार को रोकना चाहते हैं  
 {$ Event.stopPropagation (); $ Event.preventDefault (); ... & lt; बटन एनजी-क्लिक = "$ parent.mem.A = $ parent.findInHash ($ घटना, 'पिछला', 'ए')" & gt; ...

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
