SharePoint 2010中WebPart属性的下拉列表

Question

Hi I am creating a visualwebpart in sharepoint 2010 with some webpart property. In webpart property I am trying to creating a dropdown using enum.

public enum FileTypeSupport
    {            
        OnlyImage,
        OnlyVideo,
        ImageAndVideo
    };
    public static FileTypeSupport fileType;

    [Personalizable(PersonalizationScope.Shared),
    Category("Caustom Property"),
    WebBrowsable(true),
    WebDisplayName("File Type Support"),
    Description("Specify the number of image which will show at a time")]
    public FileTypeSupport SelectedfileType
    {
        get { return fileType; }
        set { fileType = value; }
    }

This is working fine but my requirement is to dropdown of {Only Image, Only Video,Image And Video}, ie with some space(OnlyImage-->Only Image), but it is not supporting in enum. Can anyone tell me how can I fullfill that requirement.

Answer 1

IF I understand you right here you want to display "Only Image" when "OnlyImage" is selected?

Then you have to possibilities: Posibillity ONE: Use a

public Dictionary<enum,string> SelectedFileType {

}

Where the enum contains: (FileTypeSupport.OnlyImage, "Only Image")

Possibility TWO: If you have exact rules you can modify the getter and setter:

public string SelectedfileType
{
get { return Regex.Replace(fileType.ToString(), "([a-z])([A-Z])", "$1 $2")); }
set { fileType=enum.Parse(typeOf(FileTypeSupport),value.Replace(" ","");
}

I stole the Getter from this SO answer . You can also find other answers there without regex which have a better performance. (But performance should not really be a problem as you use SharePoint)
