Property Value

Type Description

A string that specifies a field name.

Remarks

This argument is used to specify a data source field (column) that corresponds to a cell customized via the HtmlDataCellDecoration event. 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";
            }
        }
    }
}
