大佬教程收集整理的这篇文章主要介绍了MVVM DataGrid ComboBox SelectedValue Bindfing 模型 - 员工（第一个数据网格）模型 - 部门（第二个数据网格）视图模型MainView.xaml，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
@H_502_0@在我的情况下，当我从组合框中选择一种材料时，我希望自动放置 CoefD 列。 这是我的代码。
@H_502_0@当我保存文件并想打开所选的材料时，我想留在那里。@H_502_0@Picture with the program datagrids Click

首先请您理解，这是我制作的示例代码，而不是您使用的代码。
整个源代码位于 Github 中。
public class employees
{
public String Name { get; set; }
public int age { get; set; }
public Department Department { get; set; }
}
public class Department
{
public String DepartmentCode { get; set; }
public String DepartmentName { get; set; }
}
将你想要绑定的模型(Department)作为employee类中的一个变量。
public class MainViewModel : ObservabLeobject
{
private ObservableCollection<employees> _employees;
public ObservableCollection<employees> employees
{
get { return _employees; }
set { _employees = value; OnPropertyChanged(); }
}
private ObservableCollection<Department> _departments;
public ObservableCollection<Department> Departments
{
get { return _departments; }
set { _departments = value; OnPropertyChanged(); }
}
private String _departmentName;
public String DepartmentName
{
get { return _departmentName; }
set { _departmentName = value; OnPropertyChanged(); }
}
public MainViewModel()
{
employees = Getemployees();
Departments = GetDepartments();
}
private ObservableCollection<employees> Getemployees()
{
ObservableCollection<employees> employees = new ObservableCollection<employees>
{
new employees { Name = "James",Age = 30 },new employees { Name = "Elena",Age = 26 },new employees { Name = "Rookie",Age = 38 }
};
return employees;
}
private ObservableCollection<Department> GetDepartments()
{
ObservableCollection<Department> departments = new ObservableCollection<Department>
{
new Department { DepartmentCode = "0001",DepartmentName = "Develop" },new Department { DepartmentCode = "0002",DepartmentName = "MarkeTing" },new Department { DepartmentCode = "0003",DepartmentName = "HR" }
};
return departments;
}
}
<Grid VerticalAlignment="Top">
<Grid.columnDefinitions>
<columnDefinition Width="3*"/>
<columnDefinition Width="2*"/>
</Grid.columnDefinitions>
<DataGrid AutoGeneratecolumns="false" SELEctionMode="Single" CanUserAddRows="false"
Itemssource="{Binding employees}" Grid.column="0" AlternaTingRowBACkground="#F1F1F1" Height="100">

<DataGridTextcolumn Header="Name" Binding="{Binding NamE}" IsReadOnly="True" Width="70"/>
<DataGridTextcolumn Header="Age" Binding="{Binding AgE}" IsReadOnly="True" Width="50"/>
<DataGridComboBoxcolumn Header="DepartmentCode" SELEctedItemBinding="{Binding Department,updatesourcetrigger=PropertyChangeD}"
DisplaymemberPath="DepartmentCode" Width="120">
<DataGridComboBoxcolumn.ElementStyle>
<Style TargetType="{x:Type ComboBox}">
<Setter Property="Itemssource" Value="{Binding Relativesource={Relativesource AncestorType=UserControl},Path=DataContext.Departments}"/>
</Style>
</DataGridComboBoxcolumn.ElementStyle>
<DataGridComboBoxcolumn.EdiTingElementStyle>
<Style TargetType="{x:Type ComboBox}">
<Setter Property="Itemssource" Value="{Binding Relativesource={Relativesource AncestorType=UserControl},Path=DataContext.Departments}"/>
</Style>
</DataGridComboBoxcolumn.EdiTingElementStyle>
</DataGridComboBoxcolumn>
<DataGridTextcolumn Header="DepartmentName" Binding="{Binding Department.DepartmentNamE}" IsReadOnly="True" Width="*"/>
</DataGrid.columns>
</DataGrid>
<DataGrid AutoGeneratecolumns="false" SELEctionMode="Single" CanUserAddRows="false"
Itemssource="{Binding Departments}" Grid.column="1" Width="250" AlternaTingRowBACkground="#F1F1F1">
<DataGrid.columns>
<DataGridTextcolumn Header="Code" Binding="{Binding DepartmentCodE}" IsReadOnly="True" Width="100"/>
<DataGridTextcolumn Header="Name" Binding="{Binding DepartmentNamE}" IsReadOnly="True" Width="*"/>
</DataGrid.columns>
</DataGrid>
</Grid>
由于整个 Department 模型都绑定到 ComboBox 的 SELEctItem，
当在 ComboBox 中选择了“DepartmentCode”时，“DepartmentName”会自动绑定。
