It allows the end user to change the appearance of the pivot table value cells with its background color, font color, font family, and font size based on the specific conditions.

To know about Conditional Formatting feature in Blazor Pivot Table component, you can check this video.

The conditional formatting can be applied at runtime through the built-in dialog, invoked from the toolbar. To do so, set the AllowConditionalFormatting and ShowToolbar properties in SfPivotView class to true. Also, include the item ToolbarItems.ConditionalFormatting within the Toolbar property in the SfPivotView class. End user can now see the “Conditional Formatting” icon in toolbar UI automatically, which on clicking will invoke the formatting dialog to perform necessary operations.

@using Syncfusion.Blazor.PivotView

<SfPivotView TValue="ProductDetails" ShowToolbar="true" Toolbar="@toolbar" AllowConditionalFormatting="true">
        <PivotViewDataSourceSettings DataSource="@data">
            <PivotViewColumns>
                <PivotViewColumn Name="Year"></PivotViewColumn>
                <PivotViewColumn Name="Quarter"></PivotViewColumn>
            </PivotViewColumns>
            <PivotViewRows>
                <PivotViewRow Name="Country"></PivotViewRow>
                <PivotViewRow Name="Products"></PivotViewRow>
            </PivotViewRows>
            <PivotViewValues>
                <PivotViewValue Name="Sold" Caption="Units Sold"></PivotViewValue>
                <PivotViewValue Name="Amount" Caption="Sold Amount"></PivotViewValue>
            </PivotViewValues>
            <PivotViewFormatSettings>
                <PivotViewFormatSetting Name="Amount" Format="C"></PivotViewFormatSetting>
            </PivotViewFormatSettings>
        </PivotViewDataSourceSettings>
</SfPivotView>

@code{
    public List<ToolbarItems> toolbar = new List<ToolbarItems> {
        ToolbarItems.ConditionalFormatting
    };
    public List<ProductDetails> data { get; set; }
    protected override void OnInitialized()
    {
        this.data = ProductDetails.GetProductData().ToList();
