WPF自动产生列，前台代码：

<DataGrid x:Name="Dg"
AutoGenerateColumns="True"
CanUserAddRows="False" AutoGeneratingColumn="Dg_OnAutoGeneratingColumn" |
DataGrid绑定DataTable

void
TestPage_Loaded(object
sender, RoutedEventArgs e) { var
dt = new
DataTable(); dt.Columns.Add("ID"); dt.Columns.Add("Name"); dt.Columns.Add("gender"); dt.Columns.Add("xAge"); DataRow newRow = dt.NewRow(); newRow["ID"] = "ID"; newRow["Name"] = "Name"; newRow["gender"] = "gender"; newRow["xAge"] = "xAge"; dt.Rows.Add(newRow); Dg.ItemsSource = dt.DefaultView; } |
因为数据源不固定（列名、列个数都不固定），所以必须自动生成列，并为每一列绑定下拉框；
下拉框的默认选中项为列的标题。实现字段映射功能

Dg_OnAutoGeneratingColumn(object
sender, DataGridAutoGeneratingColumnEventArgs e) { var
sexType = new
List<string> { "Age", "gender", "ID", "Name","Country"
}; var
column = new
DataGridTemplateColumn { Header = e.PropertyName }; var
dataTemplate = new
DataTemplate(); var
fef = new
FrameworkElementFactory(typeof(ComboBox)); var
binding = new
Binding { Source = sexType }; fef.SetBinding(ItemsControl.ItemsSourceProperty, binding); var
selectVal = new
Binding(e.PropertyName);//根据列名设置默认值 fef.SetBinding(Selector.SelectedValueProperty, selectVal); dataTemplate.VisualTree = fef; column.CellTemplate = dataTemplate; e.Column = column; e.Column.Width = 100; } |
效果图：
WPF AutoGeneratingColumn 绑定下拉框
