मैं एक प्रतिनिधि सूची में एक TreeView में कैसे प्राप्त करूं विस्तारित इवेंट?

क्या मुझे डेलिटेक कॉमांड का उपयोग करना चाहिए या कोई अन्य तरीका है?

धन्यवाद

चूंकि आप प्रिज्म का उल्लेख कर रहे हैं, मुझे लगता है कि आपके नियंत्रक या ViewModel को आपके TreeView वाले दृश्य से जुड़ा है ...

यह मामला है, एक बूलियन संपत्ति बेनकाब करना 

  निजी बूल _isExpanded; सार्वजनिक बूल आईईएक्सपेंडेड {get {return_isExpanded; } सेट {if (value! = _isExpanded) {_isExpanded = value; RaisePropertyChanged ( "IsExpanded"); // कस्टम लॉजिक लागू करें ...}}}

अब TreeView तक इस प्रॉपर्टी को हुक करवाने के लिए, आपको ट्री व्हीव के संसाधनों में निम्नलिखित शैली को लागू करने की आवश्यकता है (या आगे दृश्य पेड़ उपयुक्त के रूप में) 

  शैली लक्ष्य प्रकार = "{x: प्रकार ट्री वीआईआईआईटीम}" & gt; & Lt; सेटर संपदा = "आईईएक्सपैन्डड" मान = "{बाध्यकारी पथ = आइएक्सपैंन्डड, मोड = दोवे}" / & gt; & Lt; / शैली & gt;

NB: आप एक ऐसी तकनीक का उपयोग भी कर सकते हैं जिसे आईएसईचुटेड संपत्ति को हुक कर सकते हैं - यह भी बहुत उपयोगी है!

Just want to know how I will create UIPickerView in a UIActionSheet with a simple array.

Please help anyone. I know that this is a stupid question, but I'm cheating my head on my $$$$$$ MacBook. Instead you want to do this, create your UIPickerView interface builder and have it in your view controller Connect to the outlet. Add it as a subview of your main view and set its frame coordinates so that it is offset right below the edge, x = 0, y = 480 Then, when you want to display a picker, animate it like something with the screen: [UIView startup permissions: zero reference: zero]; [Color picture setfr...

java - Is there an object like a "Set" that can contain only unique string values, but also contain a count on the number of occurrences of the string value? -

There is an object like "set" in Java that can contain only unique string values, but it also includes a count Is the number of string value in number? This idea is simple. A data set, ALA ... ABBCCC I will set the text of each line set- I want to add to the object every time a non-unique text is added to the set, I also want to show a numeric value associated with the set to show how often it was added. So if I run it on the above data then set output will be something like this: A: 1B: 2C: 3 Any ideas? Maps & lt; String, integer & gt; add public null (strings) {if (map.containsKey (s)) {map.put (s, map.get (s) + 1); } And {map.put (S, 1); }}
