Question

我正试图找出方法。

背景：基本上，我是通过DataGrid将Google Spreadsheet的内容移植到WPF应用程序的。 Spreadsheet每列都有一个下拉菜单，用于查找另一张表上的值，因此用户只能为该列中的该单元格选择有效数据，而不用输入任何内容。我已经在字典中加载了这些LookupValues，以及在使用TextColumns时在DataGrid单元格中具有工作表数据。最后一步是使用ComboBoxColumns而不是TextColumns，但是我还不知道如何加载和绑定它们并显示正确的值，因此在WPF应用程序中，当打开ComboBox下拉列表时，它将显示可选值，并且仅允许这些值

我有一个表示列的枚举

    public enum ColumnEnumeration
    {
        Time = 0,
        ReplacedUser = 1,
        ReplacementUser = 2,
        Class = 3,
        Location = 4,
        AdditionalInfo = 5
    }

字典，其中每个枚举值都包含字符串列表

    private Dictionary<Replacement.ColumnEnumeration, List<String>> LookupValues;

我想绑定到我的DataGrid组合框

        <DataGrid Name="ExcelDataView" Grid.Row="1"
                  BorderThickness="1 0 1 1" BorderBrush="Black"
                  HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
                  AutoGenerateColumns="False" 
                  ColumnWidth="*"  
                  RowBackground="WhiteSmoke"  
                  Background="LightBlue"
                  CanUserAddRows="False"                                            
                  BeginningEdit="ExcelDataView_BeginningEdit"
                  CellEditEnding="ExcelDataView_CellEditEnding"                       
                  RowEditEnding="ExcelDataView_RowEditEnding">
            <DataGrid.Columns>
                <DataGridComboBoxColumn Header="Time" ItemsSource="{Binding TimeText, Mode=TwoWay}" Width="70" CanUserSort="False" />
                <DataGridComboBoxColumn Header="Replaced User" ItemsSource="{Binding ReplacedUser, Mode=TwoWay}" Width="140" CanUserSort="False" />
                <DataGridComboBoxColumn Header="Replacement User" ItemsSource="{Binding ReplacementUser, Mode=TwoWay}" Width="140" CanUserSort="False" />
                <DataGridComboBoxColumn Header="Class" ItemsSource="{Binding Class, Mode=TwoWay}" Width="170" CanUserSort="False" />
                <DataGridComboBoxColumn Header="Location" ItemsSource="{Binding Location, Mode=TwoWay}" Width="170" CanUserSort="False" />
                <DataGridComboBoxColumn Header="Info" ItemsSource="{Binding AdditionalInfo, Mode=TwoWay}" CanUserSort="False" />
                <DataGridCheckBoxColumn Header="Mark" Binding="{Binding Marked, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" CanUserSort="False" Width="50">
                    <DataGridCheckBoxColumn.CellStyle>
                        <Style>
                            <EventSetter Event="CheckBox.Checked" Handler="OnExcelDeleteColumnChecked"/>
                            <EventSetter Event="CheckBox.Unchecked" Handler="OnExcelDeleteColumnUnchecked"/>
                        </Style>
                    </DataGridCheckBoxColumn.CellStyle>
                </DataGridCheckBoxColumn>
            </DataGrid.Columns>
        </DataGrid>

以及已经加载了其内容的DataGrid

        ExcelDataView.ItemsSource = Replacement.LoadFromExcel(GoogleCore.SheetService, fileId, ActiveDate.ToString(Settings.SpreadsheetSheetNameFormat), Settings.SpreadsheetDataRange);

我可以找到但还没有找到的示例。

如何将Dictionary <enum，list <string =“” >>绑定到具有ComboBox的DataGrid
