上一篇文章，当我添加两个coloumn标题时，我正在获取文件名和大小

 private void AddGridColumn(string name, string uniqueName, bool sortable)
          {
         RemoveGridColumn(uniqueName);
         // Add a new column with the specified name
         GridTemplateColumn gridTemplateColumn1 = new GridTemplateColumn();
         gridTemplateColumn1.HeaderText = name;
         if (sortable)
        gridTemplateColumn1.SortExpression = uniqueName;
        gridTemplateColumn1.UniqueName = uniqueName;
        gridTemplateColumn1.DataField = uniqueName;
        Aspx_RadFileExplorer.Grid.Columns.Add(gridTemplateColumn1);
         }

Function For ResolveRootDirectoryAsTree 
    <pre>
     public override DirectoryItem ResolveRootDirectoryAsTree ( string xszPath )
     {
    PathPermissions zPathPermission = FullPermissions;
    if ( xszPath.Equals ( "Document/Private" ) )
    zPathPermission = PathPermissions.Read;
    else if ( xszPath.Equals ( "Document/Public" ) )
    zPathPermission = PathPermissions.Read | PathPermissions.Upload;
         return new DirectoryItem(GetName(xszPath), GetDirectoryPath(xszPath), xszPath, GetDate(xszPath), zPathPermission, GetChildFiles(xszPath), GetChildDirectories(xszPath));
   }
</pre>

ResolveDirectory的功能

    public override DirectoryItem ResolveDirectory(string xszPath )
    {
    PathPermissions zPathPermission = FullPermissions;
    if ( xszPath.Equals ( "Document/Private" ) )
    zPathPermission = PathPermissions.Read;
    else if ( xszPath.Equals ( "Document/Public" ) )
    zPathPermission = PathPermissions.Read | PathPermissions.Upload;

DirectoryItem[] zdlDirectories = GetChildDirectories ( xszPath );
                   return new DirectoryItem ( GetName ( xszPath ), EndWithSlash ( GetDirectoryPath ( xszPath ) ), string.Empty, string.Empty, zPathPermission, GetChildFiles ( xszPath ), zdlDirectories );
}
private string GetName ( string xszPath )
{
if ( xszPath == null )
{
    return string.Empty;
}
 return xszPath.Substring ( xszPath.LastIndexOf ( '/' ) + 1 );
}

在此函数中，我将获取OwnerID和Date作为字符串LoadDocuments（）。如何将所有者ID显示为所有者自定义字段和日期到日期字段

以下是文档的a link，以下是代码。

// Add a new 'custom column for the file owner'
GridTemplateColumn gridTemplateColumn2 = new GridTemplateColumn();
gridTemplateColumn2.HeaderText = "Owner Name";
gridTemplateColumn2.SortExpression = "Owner";
gridTemplateColumn2.UniqueName = "Owner";
gridTemplateColumn2.DataField = "Owner";
RadFileExplorer1.Grid.Columns.Add(gridTemplateColumn2);// Add the second column

//And the code for adding value for the file entry for the custom column.
public override DirectoryItem ResolveDirectory(string path)
{
    // Update all file items with the additional information (date, owner)
    DirectoryItem oldItem = base.ResolveDirectory(path);
    foreach (FileItem fileItem in oldItem.Files)
    {
        // Get the information from the physical file
        FileInfo fInfo = new FileInfo(Context.Server.MapPath(VirtualPathUtility.AppendTrailingSlash(oldItem.Path) + fileItem.Name));
        // Add the information to the attributes collection of the item. It will be automatically picked up by the FileExplorer
        // If the name attribute matches the unique name of a grid column
        fileItem.Attributes.Add("Date", fInfo.CreationTime.ToString());
        // Type targetType = typeof(System.Security.Principal.NTAccount);
        // string value = fInfo.GetAccessControl().GetOwner(targetType).Value.Replace("\\", "\\\\");
        string ownerName = "Telerik";
        fileItem.Attributes.Add("Owner", ownerName);
    }
    return oldItem;
}

希望这会对你有所帮助。
