Radzen Blazor Components

Spreadsheet Custom Toolbar

Replace the built-in toolbar with your own selection of tools. Pick from the public tool components, reorder them, group them as you like, and add custom tools that dispatch undoable commands.

Predefined tools in a custom layout link

Add any of the RadzenSpreadsheet* tool components (e.g. RadzenSpreadsheetBold, RadzenSpreadsheetColor) to the spreadsheet's ChildContent. The host cascades the active Worksheet so the tools wire themselves up - no parameters needed. Include RadzenSpreadsheetTableDesignToolset to keep the contextual Table Design toolset.

Custom tool with an undoable command link

Build your own tool component and dispatch a custom ICommand through ISpreadsheet.ExecuteAsync. Declare a SpreadsheetFeature on the command and your tool participates in ReadOnly, the matching Allow* flag, the CommandExecuting event, and the undo/redo stack for free.
