    text
    copied!<p>I have a strange problem with reference and object cloning, which I'm not able to solve. I have a class MyClass which consist of property Name. I also have my custon user control, which have a property of type MyClass - myclassproperty. These controls are placed on form. If I click one of control a new form apperas. I pass one argument to new form - myclassproperty</p> <pre><code>NewForm form = new NewForm(myusercontrol.myclassproperty) this.myclassproperty = myclassproperty; clonedproperty = ObjectCloner.Clone(myclassproperty); </code></pre> <p>clonedproperty is an cloned object. For cloning I use this code, which I found here on stackoverflow</p> <pre><code> public static class ObjectCloner { /// &lt;summary&gt; /// Reference Article http://www.codeproject.com/KB/tips/SerializedObjectCloner.aspx /// /// Provides a method for performing a deep copy of an object. /// Binary Serialization is used to perform the copy. /// &lt;/summary&gt; /// &lt;summary&gt; /// Perform a deep Copy of the object. /// &lt;/summary&gt; /// &lt;typeparam name="T"&gt;The type of object being copied.&lt;/typeparam&gt; /// &lt;param name="source"&gt;The object instance to copy.&lt;/param&gt; /// &lt;returns&gt;The copied object.&lt;/returns&gt; public static T Clone&lt;T&gt;(T source) { if (!typeof(T).IsSerializable) { throw new ArgumentException("The type must be serializable.", "source"); } // Don't serialize a null object, simply return the default for that object if (Object.ReferenceEquals(source, null)) { return default(T); } IFormatter formatter = new BinaryFormatter(); Stream stream = new MemoryStream(); using (stream) { formatter.Serialize(stream, source); stream.Seek(0, SeekOrigin.Begin); return (T)formatter.Deserialize(stream); } } } } </code></pre> <p>In new form I have a textbox which is bind to filed Name in object clonedproperty</p> <p>txtName.DataBindings.Add("Text", clonedproperty, "Name");</p> <p>I also have two buttons on my form ''save'' and ''cancel''. If I click cancel, form simply is closed but if I click save I do sth like that</p> <pre><code>this.myclassproperty = clonedproperty </code></pre> <p>and the form is closed.</p> <p>In my opinion, at this moment myusercontrol.myclassproperty is reference to clonedproperty so if I click once again on myusercontrol the new value (which I entered previously) shows.</p> <p>However I have old value all the time :(</p>
