Remarks
This property is a wrapper of the FileSystemProviderBase.RootFolder property. Refer to its description for more information.
Note
- We recommend you to specify the RootFolder property on Page_Init event.
- If you change the RootFolder property value dynamically, it can result in the wrong thumbnails for files with coincident file names. In this case, specify a thumbnail folder (the FileManagerSettings.ThumbnailFolder) dynamically. To learn more, see the Security Considerations topic.
- The root folder cannot be changed during its own callbacks. Instead, use postbacks or the ASPxCallbackPanel‘s callbacks.
Example
Web Forms (declaratively):
<dx:ASPxFileManager ID="fileManager" runat="server" ...>
<Settings RootFolder="~/Content/FileManager/Files" ThumbnailFolder="~/Content/FileManager/Thumbnails"
AllowedFileExtensions=".jpg, .jpeg, .gif, .png" InitialFolder="~/Content/FileManager/Images"/>
...
</dx:ASPxFileManager>
Web Forms (in code):
ASPxFileManager fm = new ASPxFileManager();
fm.ID = "ASPxFileManager1";
fm.SettingsUpload.ValidationSettings.DisableHttpHandlerValidation = true;
Page.Form.Controls.Add(fm);
...
fm.Settings.RootFolder = Url.Content("~/Content/FileManager/Files");
fm.Settings.ThumbnailFolder = Url.Content("~/Content/FileManager/Thumbnails");
fm.Settings.InitialFolder = Url.Content("~/Content/FileManager/Images");
fm.Settings.AllowedFileExtensions=new String[] { ".jpeg", ".jpg", ".gif", ".png" };
MVC:
@Html.DevExpress().FileManager( settings => {
settings.Name = "fileManager";
settings.Settings.ThumbnailFolder = Url.Content("~/Content/FileManager/Thumbnails");
settings.Settings.RootFolder = Url.Content("~/Content/FileManager/Files");
settings.Settings.InitialFolder = "~/Content/FileManager/Images";
settings.Settings.AllowedFileExtensions= new String[] { ".jpeg", ".jpg", ".gif", ".png" };
...
}).BindToFolder(Model).GetHtml()
