问题
I need to create a TabControl in MainWindow, and then I need to make a Property in MainWindow that returns that TabControl. I don't know how to access TabControl from another window because it says "An object reference is required bla bla..." when I try like this:
MainWindow.tabcontrol.Items.Add("tabitem");
and the Property I made in MainWindow is:
public TabControl tabcontrol
{ get { return tabc; } set{ tabc = value;} }
Values are:
"tabcontrol" is name of Property
"tabc" is name of TabControl that I need in another window
Please, how do I do this? How to add items to a TabControl that is in MainWindow from another window?
this code returns error saying : "An object reference is required..."

Just create the TabControl in XAML and give it name. Your can use that name in code behind:
<TabControl x:Name="MyTabControl" ... />
In code behind just use MyTabControl.
