Visual Studio User Contol Design

Question

If you have a user control with a field like public int number = 10; can you make that value come up in the properties box when you use the designer in VS 2010 and C#?

Answer 1

You have to turn your variable into a property. Try adding Get Set and sometimes you have to add the proper attributes (referencing the System.ComponentModel class)

private int _Number = 10;

[DefaultValue(10)]
[Description("This is a number.")]
public int Number
{
  get { return _Number; }
  set { _Number = value; }
}

Note: The DefaultValue attribute is for setting the designer to bold or not. It doesn't actually set the default value.
