我有一个启用了 ImageManager 的 radEditor 控件。此功能在我们拥有的上一个版本（2011 版）中运行良好，但现在使用我们拥有的版本，图像管理器不会插入所选图像。下面是我的 radEditor html 标签：
<telerik:RadEditor ID="txtRTE"
SpellCheckSettings-AllowAddCustom="false"
ToolsFile="~/SimpleRTEEditorTools.xml"
OnClientLoad="HandleRTEClientLoad"
ExternalDialogsPath="~/RadControls/EditorDialogs/"
runat="server"
Height="200"
Skin="Default"
EditModes="Design"
AllowScripts="false"
StripFormattingOptions="All">
<ImageManager ViewPaths=".." UploadPaths=".." SearchPatterns="*.jpg,*.gif,*.png" EnableImageEditor="False" ViewMode="Grid" />
我正在 page_load 方法后面的代码中编辑 ViewPaths 和 uploadPaths：
txtRTE.ImageManager.ViewPaths = paths;
txtRTE.ImageManager.UploadPaths = paths;
txtRTE.ImageManager.ContentProviderTypeName = typeof(FolderContentProvider).AssemblyQualifiedName;
我们实现了自己的内容提供程序，如下所示：
public class FolderContentProvider : FileBrowserContentProvider
{
private string ROOT_DIRECTORY_FULL_PATH =
//Path to record documents folder
System.Configuration.ConfigurationManager.AppSettings[Constants.RECORD_DOC_ROOT_FOLDER_APP_KEY].ToString() +
//folder containing images
Constants.Record_DOC_FORM_TEXT_IMAGE_FOLDER + "\\" +
//to get Record ID
((MyAppPrincipal)System.Threading.Thread.CurrentPrincipal).Record.ID;
public string RootDirectory
{
get
{
return ROOT_DIRECTORY_FULL_PATH;
}
private set
{
}
}
private PathPermissions fullPermissions = PathPermissions.Read | PathPermissions.Upload;
private DirectoryItem[] GetSubDirectories(string path)
{
//we have only one directory no sub directories
//no need to go to file system to find that out
return new DirectoryItem[0];
}
private string GetDirectoryFullPath(string path)
{
return RootDirectory;
}
private FileItem[] GetFiles(string path)
{
string[] filesFullName = Directory.GetFiles(RootDirectory);
ArrayList files = new ArrayList();
for (int i = 0; i < filesFullName.Length; i++)
{
string fullPath = filesFullName[i];
System.IO.FileInfo currentFile = new System.IO.FileInfo(fullPath);
if (IsAlowedFileExtension(currentFile.Extension))
{
string url = string.Format("{0}?path={1}", HttpContext.Current.Request.ApplicationPath + "/app/FormTextImageHandler.ashx", currentFile.Name);
files.Add(new FileItem(
currentFile.Name, //file name
currentFile.Extension, //extension
currentFile.Length, //size
string.Empty,//currentFile.FullName, //location
url, //url
string.Empty,//tag
fullPermissions//permissions
));
}
}
return (FileItem[])files.ToArray(typeof(FileItem));
}
private bool IsAlowedFileExtension(string Extension)
{
if (Extension.Equals(".gif", StringComparison.InvariantCultureIgnoreCase))
return true;
if (Extension.Equals(".jpg", StringComparison.InvariantCultureIgnoreCase))
return true;
if (Extension.Equals(".png", StringComparison.InvariantCultureIgnoreCase))
return true;
return false;
}
public FolderContentProvider(HttpContext context, string[] searchPatterns, string[] viewPaths, string[] uploadPaths, string[] deletePaths, string selectedUrl, string selectedItemTag)
: base(context, searchPatterns, viewPaths, uploadPaths, deletePaths, selectedUrl, selectedItemTag)
{
}
public override string DeleteFile(string path)
{
//we do not allow removing files
return null;
}
public override string DeleteDirectory(string path)
{
//we don't have any sub directories
//and moreover we don't give delete rights
return null;
}
public override string StoreFile(Telerik.Web.UI.UploadedFile file, string path, string name, params string[] arguments)
{
int fileLength = (int)file.InputStream.Length;
byte[] content = new byte[fileLength];
file.InputStream.Read(content, 0, fileLength);
string fullPath = RootDirectory +"\\"+ name;
FileStream fileStream = new FileStream(fullPath, FileMode.OpenOrCreate);
fileStream.Write(content, 0, content.Length);
fileStream.Flush();
fileStream.Close();
return string.Empty;
}
public override DirectoryItem ResolveDirectory(string path)
{
DirectoryItem[] directories = new DirectoryItem[0];
FileItem[] files = this.GetFiles(RootDirectory);
DirectoryItem dir = new DirectoryItem("Images", string.Empty, RootDirectory, string.Empty, fullPermissions, files, directories);
return dir;
}
public override DirectoryItem ResolveRootDirectoryAsTree(string path)
{
//we don't have any subdirectories - everythinng is in the same folder
DirectoryItem[] directories = new DirectoryItem[0];
FileItem[] files = this.GetFiles(RootDirectory);
DirectoryItem root = new DirectoryItem("Images", string.Empty, "Images\\", string.Empty, fullPermissions, files, directories);
return root;
}
public override bool CanCreateDirectory
{
get
{
return false;
}
}
public override string CreateDirectory(string path, string name)
{
return null;
}
public override string StoreBitmap(Bitmap bitmap, string url, ImageFormat format)
{
return null;
}
public override Stream GetFile(string url)
{
return null;
}
public override string GetPath(string url)
{
return RootDirectory;
}
public override string GetFileName(string url)
{
return null;
}
[Obsolete]
public override DirectoryItem[] ResolveRootDirectoryAsList(string path)
{
return null;
}
public override bool CheckWritePermissions(string folderPath) {
return true;
}
}
知道为什么旧版本能够插入该字段，但新版本不能？
