DataGrid Row Visible Index

To change an individual row’s decoration settings, handle the HtmlRowDecoration event.

The code below handles the HtmlRowDecoration and HtmlDataCellDecoration events to color data grid cells, rows, and columns according to their values.

<DxDataGrid Data="@DataSource"
            HtmlRowDecoration="@OnHtmlRowDecoration"
            HtmlDataCellDecoration="@OnHtmlDataCellDecoration">
    <DxDataGridColumn Field="@nameof(Order.Product)"></DxDataGridColumn>
    ...
</DxDataGrid>

@code {
    IEnumerable<Product> DataSource;

    ...

    void OnHtmlRowDecoration(DataGridHtmlRowDecorationEventArgs<Order> eventArgs) {
        if (eventArgs.VisibleIndex % 2 == 1)
            eventArgs.CssClass = " table-dark";
        if (eventArgs.DataItem != null && eventArgs.DataItem.UnitsInOrder > largeOrder)
            eventArgs.CssClass = " table-warning font-weight-bold";
        else
            eventArgs.Attributes.Add("data-low-price", "");
    }
    void OnHtmlDataCellDecoration(DataGridHtmlDataCellDecorationEventArgs<Order> eventArgs) {
        eventArgs.CssClass += " border-0";

        if (eventArgs.FieldName == nameof(Order.Product)) {
            if (eventArgs.RowVisibleIndex % 2 == 1)
                eventArgs.Style += " background-color: rgb(169, 148, 200); color: black;";
            else
                eventArgs.Style += " background-color: rgb(210, 198, 233); color: black;";

            if (eventArgs.DataItem.UnitsInOrder > largeOrder) {
                eventArgs.CssClass += " font-weight-bold";
            }
        }
    }
}
