c# - DataGrid cell edit Mode=TwoWay -

-

मेरे पास DataGrid जैसा नीचे दिया गया है 

  & lt; DataGrid आइटमस्सोर्स = "{बाध्यकारी टेम्पलेट्स}" चुने हुए इटैम = "{बाइनिंग चुने हुए टेम्प्लेट, मोड = टूवे, अपडेटससोर्सट्रिगर = प्रॉपर्टी चेंंकित}" कैन्यूर्सरोर्ट कॉलम = "फॉल्स" & gt; & LT; DataGrid.Columns & gt; & Lt; DataGridTextColumn हेडर = "टेम्प्लेट" बाइंडिंग = "{बाध्यकारी पथ =।, मोड = दोवे, अपडेटसॉर्सट्रिगर = संपत्ति बदलते}" चौड़ाई = "*" / & gt; & LT; /DataGrid.Columns> & Lt; / डेटा ग्रिड & gt;

प्रश्न में दो प्रॉपर्टी नीचे दी गई हैं 

  निजी ऑब्ज़र्वबल कलेक्शन & lt; string & gt; _templates; सार्वजनिक पर्यवेक्षण कलेक्शन & lt; स्ट्रिंग & gt; टेम्पलेट {प्राप्त करें {रिटर्न _ टेम्पलेट्स; } सेट {यदि (_templates == मान) रिटर्न; _templates = value; RaisePropertyChanged ( "टेम्पलेट्स"); }} निजी स्ट्रिंग चुने गए चुने गए; सार्वजनिक स्ट्रिंग चयनितमेटलेट {प्राप्त करें {लौटें चुने गए चुने गए टेम्पलेट; } सेट {if (_selectedTemplate == मान) रिटर्न; _selectedTemplate = मान; RaisePropertyChanged ( "SelectedTemplate"); }}

मैं UI से उपरोक्त DataGrid में कोशिकाओं का संपादित करें कार्य करना चाहता हूं और संबंधित परिवर्तन उपलब्ध होना चाहिए

अब के रूप में स्ट्रिंग वर्ग INotifyPropertyChanged को कार्यान्वित नहीं करता है, UI में संपादन कोशिकाओं संपत्तियों के मूल्यों में परिवर्तन को प्रतिबिंबित नहीं करती है। तो क्या किसी के पास कोई विचार है यदि इसके लिए एक वैकल्पिक हल है ताकि मैं आवश्यक कार्यक्षमता प्राप्त कर सकूं?

आपके पास यहां बहुत पसंद नहीं है ... एक स्ट्रिंग टेम्पलेट संपत्ति के साथ एक TemplateModel वर्ग बनाएँ। इसे INotifyPropertyChanged कार्यान्वित करें और इसे परिवर्तित करें:

  • Templates से ObservableCollection
  • का चयन किया गया टेम्पलेट < to TemplateModel
  • के लिए बाध्यकारी {बाध्यकारी पथ = टेम्पलेट, मोड = दोवा, अद्यतनसंसाधनट्रीजर = संपत्ति बदल गया}

I am trying to use the ASP.NET signal for the first time - here's what I did: created a new web Has been added to the project and the following signal R packages: I have created the following category: [Hub-name ("chat")] Public class ChatHub: Hub {Public Zero Halo () {Clients.All.hello ( ); }} and the following startup configuration: public partial class startup {public zero configuration (IAppBuilder app) {configure (app); App.MapSignalR (); }} However, whenever I navigate localhost: (port) / api / signalr / chat I get the following error: Protocol error: Unknown transport.

Using KV lang on my Python code, I have taken a hard time trying to instantiate a dynamic class, the following Consider the code: My test.kv file looks like this: & lt; MyPopup @ popup: Title: 'Hello' size_hunt: (1, .6) Grid layout: ID: RouteGrid column: 2 padding: ['8dp', '4dp', '8dp', '4dp'] Difference: '8dp' label: text: 'some text here' button: text: 'OK' On_press: do_something () & lt; MyGrid & gt;: Rows: 1 Button: Text: 'Show Popup' on_press: root.pop.show () Then import Kivy.app into my test.py: I get the following error: raise Factory Exception ('Uncount Class' '% name) kivy.factory.FactoryException: Unknown class Can anyone tell me how to do this properly, what do I remember? If you need more information please let me know Thank you. Takes a call to the factory before the KV file is loaded, so you want the class to Are not yet in existence. As long as no clas...

svn - Cannot merge back into trunk, must be ancestrally related. But they *are* related as far as I understand -

So I'm trying to merge back into my trunk, but I'm getting errors saying that I Because they are not related to the ancestors but I am not clear why this is why. Here is the graph generated by TartiSesWN The trunk is at the bottom left (14698) Currently, I am starting with the merger in the trunk (15 9 7 9) from the top right, this is an example which claims that it is not related to the ancestors, some disparities in it That is what a coworker presented, and I'm not sure it could be the reason for this. If you notice, in the right middle, the branch with modification number 15406 actually divides a tag. It seems incredibly wrong to me, but I'm not sure. A few months ago the coworker did this (he does not work here anymore). However, they should be related to all ancestors because they come from all trunk, right? If this is true, then why am I getting this error? Will a tag be divided? The head of the trunk is 16063 (as per the figure), 14698 merge-s...
