Question

我有以下课程，我想绑定到一个网格，但它没有工作 - 任何指导赞赏

第1课：

public class Assessments

{

public AssessmentHeader AssessmentHeader { get; set; }

public ObservableCollection<AssessmentSurveyHeaders> AssessmentSurveys { get; set; }

}

Class 2:

public class AssessmentSurveyHeaders

{

public AssessmentSurvey AssessmentSurvey { get; set; }

public ObservableCollection<SurveyLines> AssessmentSurveyLines { get; set; }

 }

Class 3:

public class AssessmentSurvey 

{

public Guid SurveyId{ get; set; }

 public string Description{ get; set; }

}

网格绑定：

                <data:DataGrid x:Name="QuestionGrid" ColumnHeaderStyle="{StaticResource DataGridHeaderGlassEffect}" AutoGenerateColumns="False" ItemsSource="{Binding _Assessments, Mode=TwoWay}" HorizontalAlignment="Stretch" >
            <data:DataGrid.Columns>
                    <data:DataGridTemplateColumn Header="Assessment">
                        <data:DataGridTemplateColumn.CellTemplate >
                            <DataTemplate>
                                    <HyperlinkButton x:Name="AssessmentLink" Tag="{Binding AssessmentHeader.AssessmentGuid}" Content="{Binding AssessmentHeader.AssessmentGuid}" Click="AssessmentLink_Click"/>
                            </DataTemplate>
                        </data:DataGridTemplateColumn.CellTemplate>
                    </data:DataGridTemplateColumn>
                        <data:DataGridTemplateColumn Header="SurveyId">
                            <data:DataGridTemplateColumn.CellTemplate >
                                <DataTemplate>
                                    <data:DataGrid x:Name="SurveysGrid" AutoGenerateColumns="False" ItemsSource="{Binding AssessmentSurveys, Mode=TwoWay}" HorizontalAlignment="Stretch" >
                                        <data:DataGrid.Columns>
                                            <data:DataGridTextColumn Header="Id"  Binding="{Binding AssessmentSurveys.AssessmentSurvey.SurveyGuid, Mode=TwoWay}"  IsReadOnly="True"/>
                                            <data:DataGridTextColumn Header="Description"  Binding="{Binding AssessmentSurveys.AssessmentSurvey.Description, Mode=TwoWay}"  IsReadOnly="True"/>
                                        </data:DataGrid.Columns>
                                    </data:DataGrid>               
                                </DataTemplate>
                            </data:DataGridTemplateColumn.CellTemplate>
                        </data:DataGridTemplateColumn>
                    </data:DataGrid.Columns>
                </data:DataGrid>

Answer 1

ID和描述已经与ItemsSource的AssessmentSurveys绑定。

换句话说，您不需要编写每个子项的 AssessmentSurveys 。

请在下面尝试。

                         <data:DataGrid.Columns> 
                                        <data:DataGridTextColumn Header="Id"  Binding="{Binding AssessmentSurvey.SurveyGuid, Mode=TwoWay}"  IsReadOnly="True"/> 
                                        <data:DataGridTextColumn Header="Description"  Binding="{Binding AssessmentSurvey.Description, Mode=TwoWay}"  IsReadOnly="True"/> 
                                    </data:DataGrid.Columns>
