WPF C# button click event in code behind

Question

I have create a button in code behind , but how do i write their click event? is it MouseDown? like this ? Basically i want to detect if the button is being pressed then i populate a textbox with some text.

Button btn1 = new Button();
btn1.Content = qhm.Option1;
sp1.Children.Add(btn1);

if (btn1.MouseDown = true)
{
   tbox.Text = qhm.Option1;
}

Solution 1

Like that:

Button btn1 = new Button();
btn1.Content = qhm.Option1;
btn1.Click += btn_Click;
sp1.Children.Add(btn1);


//separate method
private void btn_Click(object sender, RoutedEventArgs e)
{
    tbox.Text = qhm.Option1;
}

using lambda:

btn1.Click += (source, e) =>
{    
    tbox.Text = qhm.Option1;
};

you can now access local variables.

Solution 2

You can add a click event like this:

        Button btn1 = new Button();
        btn1.Content = qhm.Option1;
        sp1.Children.Add(btn1);
        btn1.Click += btn1_Click;

Than you can edit the event method to add some text to your text box.

void btn1_Click(object sender, System.Windows.RoutedEventArgs e)
        {
           tbox.Text = qhm.Option1;
        }

Solution 3

You want to subscribe to the click event:

Button btn1 = new Button();
btn1.Content = "content";
btn1.Click+=btn1_Click;
sp1.Children.Add(btn1);

private void btn1_Click(object sender, RoutedEventArgs e)
{
    MessageBox.Show("You clicked it");
}

Solution 4

..
btn1.Click += btn1_Click;

private void btn1_Click(object sender, RoutedEventArgs e)
{
    ...
}

Solution 5

Register a handler for the click event:

btn1.Clicked += myHandler_Click;
private void myHandler_Click(object sender, RoutedEventArgs e)
{
  // your code
}
