    copied!<p>thank you for reading my question.</p> <p><strong>Situation:</strong></p> <p>I have an observable collection</p> <pre><code>CheckableTags = new ObservableCollection&lt;CheckableListItem&lt;Item&gt;&gt;(); </code></pre> <p>The wrapper class <code>CheckableListItem&lt;Item&gt;</code> adds a bool per object Item.</p> <pre><code>public class CheckableListItem&lt;T&gt; : INotifyPropertyChanged { private bool mIsChecked; private T mItem; public event PropertyChangedEventHandler PropertyChanged; public CheckableListItem(T item) { mItem = item; } public bool IsChecked { get { return mIsChecked; } set { mIsChecked = value; OnPropertyChanged("IsChecked"); MeasConSettings.Current.CheckableTags_CheckedChanged("ENTIRE OBJECT HERE"); } } public T Item { get { return mItem; } set { mItem = value; OnPropertyChanged("Item"); } } protected virtual void OnPropertyChanged(string propertyName) { var handler = PropertyChanged; if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName)); } } </code></pre> <p>When the user checks the checkbox, the bool variable is changed, this is why I fire the function <code>MeasConSettings.Current.CheckableTags_CheckedChanged("ENTIRE OBJECT HERE");</code> in the property of the bool variable.</p> <p>The function is as following:</p> <pre><code>public void CheckableTags_CheckedChanged(object sender) {} </code></pre> <p><strong>My question is:</strong> How can I send the entire object from the property of the bool to the function in my viewmodel, what should I send in the field "ENTIRE OBJECT HERE" in order to receive an object of CheckableListItem class with 2 elements the bool variable and the Item.</p> <p>If possible get a reference to the object so I can copy it in the receiving function.</p> <p><strong>Alternatives:</strong> If this is not possible, what else can I do? </p> <p>Thanks in advance.</p>
