FileManager Toolbar

Updated on Oct 1, 2026

The Blazor FileManager Toolbar can render built-in and custom tools. This article describes the built-in tools and shows how to add custom tools or customize the toolbar.

Built-in Tools

By default, the Blazor FileManager displays all its built-in tools in the order below. Use the tool tag if you need to define a tool explicitly in a custom toolbar configuration.

Tool NameTool TagDescription
New FolderFileManagerToolBarNewFolderToolA button that creates a new folder in the current location. Read how to handle the creation in the FileManager Events article.
UploadFileManagerToolBarUploadToolA button that opens a dialog with integrated Upload component. Read more in the FileManager Upload article.
Sort DirectionFileManagerToolBarSortDirectionToolA ButtonGroup with ToggleButtons that selects the sort direction (ascending or descending) to sort the files in the current location.
Sort ByFileManagerToolBarSortToolA SplitButton that selects the desired sort member to sort by.
ViewsFileManagerToolBarFileViewToolA ButtonGroup with ToggleButtons that toggles the file and folder visualization between a ListView and a Grid.
View DetailsFileManagerToolBarViewDetailsToolA Switch that toggles the visibility of the FileManager Preview Pane. By default, the preview pane is hidden.
SearchFileManagerToolBarSearchToolA TextBox that filters the files by name.

By default, the FileManager Toolbar also includes a spacer (<FileManagerToolBarSpacer />). This spacer consumes the available empty space and pushes the rest of the tools next to one another.

Custom Tools

In addition to built-in tools, the FileManager also supports custom tools. Use the <FileManagerToolBarCustomTool> tag, which is a standard Blazor RenderFragment. See the example below.

Toolbar Configuration

Add a <FileManagerToolBar> tag inside <TelerikFileManager> to configure a custom toolbar, for example:

  • Arrange the FileManager tools in a specific order;
  • Remove some of the built-in tools;
  • Add custom tools.

Customize the FileManager Toolbar
