Hi Carl,
Thanks for your update.
Now I got some idea. But I have one more issue. 
During button click the I need all the properties in textbox in TabPage1 to the textbox in NewTabPage(refer above image). but later if we change in text in any textbox the replaced text should not reflects the other text.
E.g: If textbox.text="Microsoft";
during buttonclick i need the textbox in New Tab Page should be Microsoft. 
later if I edit the text should not New Tab Page or TabPage1 the text should not reflects from one control to other.

Hello,
I could get what you are dealing with now, and to get that done, I would recommend you use the following way.
1. Add properties to UserControl, you could define the names of these properties with custom rules.
public partial class UserControl1 : UserControl
public UserControl1()
InitializeComponent();
public string StrTxtBox1
get { return this.textBox1.Text ; }
set { this.textBox1.Text = value; }
2. Use similar way you shared and edit it to just copy the specific properties.
TabPage newPage = new TabPage("NewTabPage");
newPage.UseVisualStyleBackColor = tabControl1.TabPages[0].UseVisualStyleBackColor;
foreach (Control c in tabControl1.TabPages[0].Controls)
Control cNew = (Control)Activator.CreateInstance(c.GetType());
PropertyDescriptorCollection pdc = TypeDescriptor.GetProperties(c);
foreach (PropertyDescriptor entry in pdc)
if (entry.DisplayName == "StrTxtBox1"|| entry.DisplayName == "Location")
object val = entry.GetValue(c);
entry.SetValue(cNew, val);
newPage.Controls.Add(cNew);
tabControl1.TabPages.Add(newPage);
In this case, if we have a lot perproties to copy, you could consider capture them by the custom rules you defined at #1 like this one.
if (entry.DisplayName.Contains("StrTxt")|| entry.DisplayName == "Location")
object val = entry.GetValue(c);
entry.SetValue(cNew, val);
Result:
And if possible, you could consider using this way which just copies the Text , Location or any other property and we don't need to create any usercontrol.
TabPage newPage = new TabPage("NewTabPage");
newPage.UseVisualStyleBackColor = tabControl1.TabPages[0].UseVisualStyleBackColor;
foreach (Control c in tabControl1.TabPages[0].Controls)
Control cNew = (Control)Activator.CreateInstance(c.GetType());
PropertyDescriptorCollection pdc = TypeDescriptor.GetProperties(c);
foreach (PropertyDescriptor entry in pdc)
if (entry.DisplayName == "Text" || entry.DisplayName == "Location")
object val = entry.GetValue(c);
entry.SetValue(cNew, val);
newPage.Controls.Add(cNew);
tabControl1.TabPages.Add(newPage);
