user control - public property

Been away from Windows Form Controls dev for a while.

I have a control that displays the date and time in a label.

I want to create a property that is visible in the visual studio "Properties" window, such that I can grab the current contents of the label any time I want to.

I think attributes are used, but I don't remember how to do it.

Thanks, and please include small 'hello world" sample C# code for me.

I just added a Property to the UserControl and it automatically appeared in the Properties Pane when the control was selected.

For example:
    public partial class DateTimeControl : UserControl
    {
        public DateTimeControl()
        {
            InitializeComponent();
            CurrentDateTime = DateTime.Now;
        }

        private DateTime currentDateTime;

        public DateTime CurrentDateTime
        {
            get
            {
                return this.currentDateTime;
            }
            set
            {
                this.currentDateTime = value;
                this.label1.Text = this.currentDateTime.ToString();
            }
        }

    }

Open in new window


Here it is in the Properties Pane:

My interim solution:

namespace DateTimeControl
{
    public partial class UserControlDateTime: UserControl
    {
        public UserControlDateTime()
        {
            InitializeComponent();
        }


        [Description("DateTime displayed by the label"), Category("Data")]
        public string LabelDateTimeText
        {
            get { return labelDateTime.Text; }            
        }
        private void timerTick_Tick(object sender, EventArgs e)
        {
            DateTime dt = new DateTime();
            dt = DateTime.Now;
            labelDateTime.Text = dt.ToLongDateString() + " " + dt.ToLongTimeString();
        }

      
    }
