wpf - How Do you Declare a Dependancy Property in VB.Net 3.0 -

My company is stuck at .NET 3.0. I am trying to solve the task is simple, I have pairing Isckikrit property checkbox Risolwsseediar to CompletesCEDARWork your audio category. The more I read about this, it seems that I have to declare fuller Edwardx as the dependent property, but I can not find a good example of how this is done. I found this example, but when I pasted your code is not "error defined me GetValue" and I have successfully treated for representing the MyCode I be any help / examples would be greatly appreciated.

Thank you

  public share ReadOnly IsSpinningProperty as DependencyProperty = DependencyProperty.Register ( "IsSpinning", GetType (Boolean), GetType (MyCode)) Public property IsSpinning () return obtained as Boolean CBool ​​(getValue (IsSpinningProperty)) end get set (ByVal value as Boolean) setValue (IsSpinningProperty, value) end set end property  

here My slim now stands as an audio class.

  Importing System. XML  

Import System Import System. IoO import system Selection. Object Model Amport System ComponentModel

public class audio

  private mXMLString string as byte as the date as the date private mEndTime as private mTarpID integer personal mStartTime Private mAudioArray () Private mFileXMLInfo as IO.FileInfo Personal as MFile XMLStream Io .filestream private mFileAudioInfo private personalized mDisplayText string as mComp as private mComp, letesCEDARWork Boolean Personal Property CompletesCEDARWork () as Boolean Go back mCompletesCEDARWork End Set (ByVal value As Boolean) mCompletesCEDARWork = value receiving end set end property  

And here's where I set my XML DataTemplate binding.

  & lt; Datatomplate x: key = "uploadableout" datatype = "audio" & gt; & Lt; Border Borderbrs = "Laitgre" Kornrredia = "8" Bordertiksaij = "1" padding = "10" Margin = "0,3,0,0" & gt; & Lt; StackPanel Orientation = "Vertical" & gt; & Lt; Text block text = "{binding path = display text}" & gt; & Lt; / TextBlock & gt; & Lt; StackPanel Orientation = "Horizontal" Vertical Element = "Center" & gt; & Lt; TextBlock Text = "TARP ID" vertical element = "center" /> & Lt; ComboBox X: Name = "ListBoxTarpIDs" ItemsSource = "{Binding Path = TarpIds}" SelectedValue = "{Binding Path = TarpID}" BorderBrush = "Transparent" Background = "Transparent" & gt; & Lt; / ComboBox & gt; & Lt; / StackPanel & gt; & Lt; Check Box X: Name = "CheckBoxResolvesCEDAR" content = "resolves CEDAR work" IsChecked = "{Binding ElementName = Audio, Path = CompletesCEDARWork, Mode = TwoWay}" /> & Lt; / StackPanel & gt; & Lt; / Border & gt; & Lt; / DataTemplate & gt;    
 
 
 You can only declare dependency properties in sections which  DependencyObject . This is why you get "GetValue not defined". You should read this basic article about dependency properties for more information. 
 
 Alternatively, you can tell by binding that the price has changed.
