  • TreeListExportCustomizeCellEventArgs.DataItem Property

    Returns the data source item that is bound to the data row being processed.

    Namespace: DevExpress.Blazor

    Assembly: DevExpress.Blazor.v25.1.dll

    NuGet Package: DevExpress.Blazor

    Declaration

    public object DataItem { get; }

    Property Value

    Type Description
    Object

    If the processed cell belongs to a data row, the property returns a data item bound to this row. Otherwise, the property returns null.

    Remarks

    Use the DataItem property to get the data source item that is bound to the data row being processed. If the current cell does not belong to a data row (the AreaType property returns a value other than DataArea), the DataItem property returns null.

    Pass the DataItem property value to the GetDataItemValue method to get the item’s field value when the TreeList is bound to a collection of anonymous objects. In other cases, you can cast the DataItem property value to the corresponding type and use the {DataItem.FieldName} notation to get the item’s field value.

    async Task ExportXlsx_Click() {
        await MyTreeList.ExportToXlsxAsync("ExportResult", new TreeListXlExportOptions() {
            CustomizeCell = CustomizeCell
        });
    }
    void CustomizeCell(TreeListExportCustomizeCellEventArgs e) {
        if (e.AreaType == DevExpress.Export.SheetAreaType.DataArea && e.ColumnFieldName == "Name") {
            var product = e.DataItem as TestModel;
            e.Hyperlink = product.Url;
            e.Handled = true;
        }
    };
