Hi,
explanation of the application:

I have a main wpf windows containing "add_button" and "view-list" button and a "content_grid" .When the user clicks the "add_button" the control containing the add form is displayed in the "content_grid" , the same when he clicks view list he gets the usercontrol containing the list + add button.

The problem that i met:

To do that i have a method in my main_window show_control(control c) that gets the control and displays it in the "content_grid". the problem is that i want to display the "add_control" from the "list_control" (the user clicks "add_btn" that is in the "list_control" to display "add_control").

Thank you in advance :)

Hello,

Use delegate in your User Control

For example you got a button named "Add" on your control:

C#

public partial class Test : UserControl
{
    public Test()
    {
        InitializeComponent();
    }

    public delegate void RunMethodHandler(object sender);
    public event RunMethodHandler RunMethod;

    private void Add_Click(object sender, RoutedEventArgs e)
    {
        if (RunMethod != null)
            RunMethod(null);
    }
}

Then in your MainWindow, Add the UserControl to MainWindow. I did and renamed it to "MyControl", then:

C#

public MainWindow()
{
    InitializeComponent();

    MyControl.RunMethod +=new Test.RunMethodHandler(TestMethod);
}

public void TestMethod(object sender)
{
    MessageBox.Show("Ok");
}

At last, when you Click on Add, the TestMethod() will run.

Good luck.
