Familiar Programming Patterns

Use your existing programming language and patterns to ship faster with less training.

Loops, conditionals, functions are natively supported. Leverage IntelliSense, inspections, navigation, and safe refactoring.

csharp

container.Column(column =>
{
    column.Item().Text("Order Items").Bold();

    if (Model.ShowSummary)
        column.Item().Element(ComposeOrderSummary);

    foreach (var item in Model.Items)
        column.Item().Element(c => ComposeItem(c, item));
});

Review document changes like any other code. Get clean diffs, PR approvals, and traceable history.

diff

void ComposeItem(IContainer container, OrderItem item)
{
    container
        .Border(1, Colors.Grey.Darken2)
        .Background(item.HighlightColor)
-       .Padding(12)
+       .Padding(16)
        .Row(row =>
        {
            row.RelativeItem().Text(item.Name);
            row.AutoItem().Text($"{item.Price:F2} USD");
        });
}
