C# WPF - DragMove window and Click Event

I am building a borderless application. What i need to achieve is to move the window by simply click and drag on an image it contains but i also want to do something when clicked.

this is how my app looks Just a button, i have functionality for left and right clicks but can't figure how to implement drag now. This is what my code looks like

private void btnHome_MouseDown(object sender, MouseButtonEventArgs e)
    {
        if(e.LeftButton == MouseButtonState.Released)
        {
            toggle();
        }
        else if(e.LeftButton == MouseButtonState.Pressed)
        {
            DragMove();
        }
    }

Right now only drag works, If i rearrange their occurrence then only left click would work. Right click functionality is working as expected right now.

Do your thing once the DragMove() method has returned, i.e. when the mouse capture has been released:

private void btnHome_MouseDown(object sender, MouseButtonEventArgs e)
{
    if (e.LeftButton == MouseButtonState.Pressed)
    {
        DragMove();
        System.Diagnostics.Debug.Write("some action...");
    }
}

Or, if you want to do something before the mouse is captured, you could use a boolean flag:

private bool _capture;
private void btnHome_MouseDown(object sender, MouseButtonEventArgs e)
{
    if (e.LeftButton == MouseButtonState.Pressed)
    {
        if (_capture)
        {
            DragMove();
            _capture = false;
        }
        else
        {
            System.Diagnostics.Debug.Write("some action...");

            _capture = true;
            btnHome.RaiseEvent(new MouseButtonEventArgs(e.MouseDevice, e.Timestamp, MouseButton.Left)
            {
                RoutedEvent = MouseDownEvent
            });
        }
    }
}

EDIT: Well I found the problem! You listen to MouseDownEvent!!!!

Just link the new event to the following new function =]

private void btnHome_MouseUp(object sender, MouseButtonEventArgs e)
{
     toggle();
}

private void btnHome_MouseDown(object sender, MouseButtonEventArgs e)
{
    DragMove();
    RaiseEvent(new MouseButtonEventArgs(e.MouseDevice, e.Timestamp, MouseButton.Left) 
    { 
        RoutedEvent = MouseLeftButtonUpEvent 
    });
}
