I have an <asp:Calendar> in my code and I want to do is that when a date is clicked, it will show the selected date on the page.
protected void Calendar1_SelectionChanged(object sender, EventArgs e)
Label1.Text = "The selected date is " + Calendar1.SelectedDate.ToShortDateString();
I followed the code instructions from here, Microsoft's website.
But I get this error.
System.NullReferenceException: Object reference not set to an instance of an object.
