### Preserve fonts when saving PDF (Blazor WebAssembly)

In Blazor WebAssembly, to preserve fonts in exported PDF use the `CustomFont` property of the SfSpreadsheet component. Provide local TrueType font (.ttf) files from wwwroot and reference them via the component.

#### How to use
- Place .ttf files under wwwroot (for example: wwwroot/Arial.ttf).
- Mark each .ttf as Content so it is published to wwwroot.
- Set the SfSpreadsheet.CustomFonts list with paths relative to wwwroot (for example: `"Arial.ttf"`).
- Only local .ttf files are supported for WASM PDF export — do not use remote URLs.
- Verify file name casing; paths are effectively case-sensitive on some hosts.

@using Syncfusion.Blazor.Spreadsheet

<SfSpreadsheet @ref="SpreadsheetRef" CustomFonts="@CustomFonts">
<SpreadsheetRibbon></SpreadsheetRibbon>
</SfSpreadsheet>

@code {
public List<string> CustomFonts = new List<string>
{
"Arial.ttf",
"Calibri.ttf",
"Courier New.ttf",
"Georgia.ttf"
};
}

{% endhighlight %}
{% endtabs %}

N> Only local TrueType (.ttf) files referenced in `CustomFonts` are fetched and embedded by the WASM PDF exporter. If a font used in the sheet is not provided, a fallback font will be used and the appearance may change.

## New
To create a new, blank workbook through the UI, select **File > New** from the **Ribbon**. This action initializes a blank spreadsheet component, ready for data entry or formatting. If unsaved changes are present, a confirmation dialog will appear, indicating that these changes will be lost. The dialog presents options to proceed with creating the new workbook by selecting **OK**, or to cancel the operation by selecting **Cancel**.
