c# - WPF Binding is not working -

-

I am working on simple MVVM applications using WPF in simple studio. I am providing code as well as model class here. My concern is only about the first textbox that is not binding with the property name of the class name. You can skip the rest of the code. I am starting for MVVM architecture and WPF if you find fit, you can also suggest mistakes to me.

Thank you.

UI.xaml 

  & lt; Window X: Class = "MVVM .view. UI" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns: x = "http://schemas.microsoft.com/winfx/ 2006 / xaml "xmlns: custom =" clr-namespace: MVVM.ViewModels "title =" UI "height =" 300 "width =" 300 "& gt; & Lt; Grid & gt; & Lt; Text box textwapping = "wrap" text = "{binding MVVM.Models.Form.Name}" margin = "20,15,160,225" /> & Lt; Text box textwapping = "wrap" text = "back color" margin = "20,73,195,167" /> & Lt; Text box textwapping = "wrap" text = "font color" margin = "20,122,195,118" /> & Lt; ListBox Name = "List Box" Item Source = "{Change Binding Notification}" Horizontal Alignment = "Left" margin = "156,42,0,143" height = "85" width = "93" /> & lt; Button content = "finish" horizontal alignment = "left" margin = "112,163,0,0" workbench = "top" width = "75" /> & Lt; / Grid & gt;   
  
  Form.cs   
  using the system; Using System.Collections.Generic; Using System.Linq; Using System.Text; Using System.ComponentModel; Namespace MVVM.Models {Public category form: INotifyPropertyChanged {public form () {} #region variable Private string _name; The name of the public string {get {return _name; } Set {_name = value; OnPropertyChanged ("name"); }} Private string _colorBack; Public string coloring {get {return _colorBack; } Set {_colorBack = value; OnPropertyChanged ("ColorBlack"); }} Private string _colorFont; Public string color_font {get {return _colorFont; } Set {_colorFont = value; OnPropertyChanged ("ColorFont"); }} #partner #region INotifyPropertyChangedMembers Private Event PropertyChangedEventHandler PropertyChanged; Private Zero OnPropertyChanged (string propertyName) {PropertyChangedEventHandler Handler = PropertyChanged; If (handler! = Null) {property changed (this, new property change event event (property name)); }} #endregion}}   
  UI.xaml.cs   
  using MVVM.Models; Using the system; Using System.Collections.Generic; Using System.Linq; Using System.Text; Using System.Windows; Using System.Windows.Controls; Using System.Windows.Data; Using System.Windows.Documents; Using System.Windows.Input; System.Windows.Media; System.Windows.Media Using imaging; Using System.Windows.Shapes; Namespace MVVM. Visual (Public Partial SQ UI: Window {Public UI ()} {InitializeComponent (); DataContext = New Form ();}}}}    
 
 
 I suspect that you missed starting the DataContext property in your UI.xaml.cs.  
 To get it started in the constructor Try  
  Public UI () {this.DataContext = new MVVM.Models.Form ();}   
 And in your UI.xaml, the name Bind the text with the property of  
  & lt; text box text wrapping Update: [details added]  
 DataInventent UI = "Wrap" text = "{binding name}" margin = "20,15,160,225" />   
 Elements are similar to the container of "object-bound" and once any UI entry is employed, the UI elements of all children will also be of reference to that binding object (type), so in our case, Form ". Datacontext is telling us UI window that Are you object binding, so all UI child UI elements will reference the binding object. Therefore, when we say that text = "{binding name}" it already knows that the binding object is form and it is to find the property of the name within that object.  
 Behind the code is actually considered as part of the view just gluing and see the simultaneous model

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
