Question

Before I start, I have to say this. I have read this question. And I dont see how its a duplicate of this question that I posted a few hours ago.

My original post as it is:

I am using a few buttons in WPF for displaying images from various folders. The Click mode for all the buttons is Hover. For some button, after hovering, it is routed to a function OnButtonClick. What I want to do is, ONLY after the mouse is over the button for X seconds, the processing inside the function OnButtonClick should be done.

XAML Code:

    <Button Name="Dresses" MouseEnter="onMouseEnter" MouseLeave="onMouseLeave" Content="Dresses" Grid.Row="2" Height="25" Width="85" VerticalAlignment="Center" Grid.Column="5"  FontFamily="Tahoma" FontSize="14" FontWeight="Bold" HorizontalAlignment="Center" Cursor="Hand" ClickMode="Hover">
        <Button.Background>
            <LinearGradientBrush>
                <GradientStop Color="Yellow" Offset="0" />
                <GradientStop Color="Green" Offset="1" />
            </LinearGradientBrush>
        </Button.Background>
    </Button>

C# Code:

    private void OnButtonClickDresses(object sender, RoutedEventArgs e)
    {
            //Code for delay

            //Code which should run only if mouse on button after 5 seconds

    }

PS: I am a beginner in WPF and C#. So if you can post a minimum working example I’d be actually very grateful.

Here is a sample application for you.

using System.Windows.Threading;

namespace MyWPF App
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>

public partial class MainWindow : Window
{

    DateTime dt;
    DispatcherTimer t;

    public MainWindow()
    {

        InitializeComponent();
        t = new DispatcherTimer();
        t.Tick += new EventHandler(t_Tick);

    }
    private void button1_MouseEnter(object sender, MouseEventArgs e)
    {
        dt=DateTime.Now;
        t.Interval = new TimeSpan(0, 0, 1);
        t.IsEnabled = true;


    }

    void t_Tick(object sender, EventArgs e)
    {

        if ((DateTime.Now - dt).Seconds >= 5)
        {
            MessageBox.Show("Hello");// Here you can put your code which you want to execute after 5 seconds.
        }

    }

    private void button1_MouseLeave(object sender, MouseEventArgs e)
    {
        t.IsEnabled = false;
    }
}

}
