How to create a "select" custom property?

Question

In a Webpart I want to set some customs properties. I have this code

[Personalizable(PersonalizationScope.Shared), WebBrowsable(true), WebDisplayName("myName"), WebDescription("myDescription"), Category("myCategory")]
        public string MyProperty
        {
            get { return _myProperty; }
            set { _myProperty= value; }
        }

that it renders a input text in the config menu. Since here its all ok.

But now I need to render another property as a select with 2 o 3 options. How can I do it?

Answer 1

You can declare an enum in your webpart and expose that as property. An enum will be rendered as a dropdown in the properties toolpane. If you need more complicated behavior you need to create a custom ToolPart.

//create enum
public enum MyColorEnum {
  Red = 0,
  Blue,
  Yellow
};

protected MyColorEnum _color;

[Personalizable(PersonalizationScope.User), WebBrowsable,
 WebDisplayName("Color"), WebDescription("Color")]
public MyColorEnum Color
{
  get { return _color; }
  set { _color = value; }
}

You have to create a custom ToolPart for your WebPart. Here is an example: http://sharepoint-insight.blogspot.com/2008/10/sharepoint-creating-web-part-with.html
