c# - How do I set dependency propertly value programmatically? -

-

इस एक्सएएमएल पर विचार करें: 

  & lt; esri: एलिमेंटलेयर नेम = "एलिमेंटलेयर" & gt; & LT; ESRI: ElementLayer.Children & gt; & Lt;! - संपादन योग्य टेक्स्टबॉक्स - & gt; & Lt; टेक्स्ट बॉक्स की चौड़ाई = "100" ऊँचाई = "20" esri: एलिमेंटलेयर। एनाफ़ेफ़ = "40,0,40,0" टेक्स्ट = "संपादन योग्य पाठ" क्षैतिज एलाइन्मेंट = "सही" वर्टिकलएलिन्मेंट = "निचला" / & gt; & Lt; / ESRI: ElementLayer.Children & gt; & Lt; / ESRI: ElementLayer & gt;

मैं इसे कोड में फिर से लिखना चाहता हूं। मेरे पास अभी तक यह है: 

  var कस्टमलेयर = this.mapControl.Layers ["ElementLayer"] एलिमेंटलेयर के रूप में; अगर (कस्टमलेयर == रिक्त) वापसी; Foreach (इस में कस्टममैपमैटम। CustomLayerData) {var tb = नया पाठ बॉक्स (); Tb.DataContext = customMapItem; // TODO: कैसे सेट करें esri: ElementLayer.Envelope = "40,0,40,0" ??? customLayer.Children.Add (टीबी); }

इसलिए, मुझे कोड में dependedncy संपत्ति सेट करने की आवश्यकता है मैं यह कैसे कर सकता हूं?

आप जो पूछ रहे हैं वह एक संलग्न निर्भरता ऑब्जेक्ट पर निर्भरता प्रदाता ।

मूल वाक्यविन्यास इस तरह दिखेगा: 

  निर्भरता ऑब्जेक्ट .सेट वैल्यू (निर्भरता प्रॉपर्टी, मायवल्यू) ;

आपके मामले में, यह इस तरह होगा: 

  customMapItem.SetValue (एलेमेंट लायर। एन्वेलपप्रॉपर्टी, नया लिफाफा (40,040,0) );

हालांकि, उन्होंने एक मानक सहायक फ़ंक्शन भी कार्यान्वित किया है, इसलिए इसे करने का एक बेहतर तरीका है: 

  एलिमेंट लायर .सेटएनवेल (कस्टममैपइटम, नया लिफाफा 40,0,40,0));

winforms - C# Form - Property Change -

-
I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
