Property Paths

You can access this nested property as listed below:

Object Type	Path to RootFolder
ASPxFileManager	.Settings .RootFolder

Remarks

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 Protect Thumbnails topic.

The root folder cannot be changed during its own callbacks. Instead, use postbacks or the ASPxCallbackPanel‘s callbacks.

For examples on how to specify the root folder, see the following topic: Root Folder.

This property is a wrapper of the FileSystemProviderBase.RootFolder property.

Example

Web Forms (in markup):

ASPX

<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):

C#

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:

C#

@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" };
    ...
