Firing event of the object added on itemcontrol from CodeBehind


  • Hi

    Can anyone help me solving this problem?

    I have button control that is added on itemcontrol from codebehind but event doesn't fire.

    My code is below.


    Dim btn As New Button

    AddHandler btn.MouseLeftButtonUp, AddressOf AddNew_MouseLeftButtonUp


    Private Sub AddNew_MouseLeftButtonUp(sender As System.Object, e As System.Windows.Input.MouseButtonEventArgs)

    End Sub


    Thank you in advance.

  • hi ,

    I tried adding a button from code  to a listbox.    I found that the mouseLeftButtonUp was not firing, as it is just a mouse button event, whereas  click event was firing as it is a routed event. 

    So making use of a routed event handler would solve your problem .

    Here's my code

      public MainPage()
                Button b = new Button();
                b.Width = 30;
                b.Height = 30;
                b.Click+=new RoutedEventHandler(b_Click);
                b.MouseLeftButtonUp += new MouseButtonEventHandler(b_MouseLeftButtonUp);

            void b_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
                MessageBox.Show("hi left");

            void b_Click(object sender, RoutedEventArgs e)
                MessageBox.Show("hi click");

    So try using the click event for the button . If you want to know more about routed events and why they will work, then please read
