DevExpress WPF GridControl的TableView和TreeListView允许你将列组织成逻辑组,这些组被称为栏(bands),每个栏(bands)由栏(bands)标题和子列组成,栏(bands)标题显示在栏(bands)子列上方的栏(bands)面板中。
创建栏(Bands)
栏(Bands)是GridControlBand对象,GridControl将其存储在GridControl.Bands集合中。
在设计时
您可以使用GridControl的Quick Actions菜单来添加栏(Bands)。
DevExpress WPF GridControlBand的的Quick Actions菜单允许您添加子栏(Bands)和列,并指定栏(Bands)的Header属性:
在XAML中
1. 将GridControlBand对象添加到GridControl.Bands集合。
2. 使用栏(Bands)的Header属性指定栏(Bands)中显示的文本。
3. 用GridColumn对象填充栏(Bands)的Columns集合。
4. 指定列设置。
XAML
<dxg:GridControl ItemsSource="{Binding Source}">
<dxg:GridControl.Bands>
<dxg:GridControlBand Header="Product">
<dxg:GridColumn FieldName="ProductName"/>
</dxg:GridControlBand><dxg:GridControlBand Header="Order Info">
<dxg:GridColumn FieldName="Country"/>
<dxg:GridColumn FieldName="City"/>
<dxg:GridColumn FieldName="OrderDate"/>
</dxg:GridControlBand><dxg:GridControlBand Header="Pricing">
<dxg:GridColumn FieldName="UnitPrice"/>
<dxg:GridColumn FieldName="Quantity"/>
</dxg:GridControlBand>
</dxg:GridControl.Bands>
</dxg:GridControl>
在代码中
C#
// Create band objects and specify their settings:
var productBand = new GridControlBand();
productBand.Header = "Product";
productBand.Columns.Add(new GridColumn() { FieldName = nameof(Product.ProductName) });var orderBand = new GridControlBand();
orderBand.Header = "Order Info";
orderBand.Columns.Add(new GridColumn() { FieldName = nameof(Product.Country) });
orderBand.Columns.Add(new GridColumn() { FieldName = nameof(Product.City) });
orderBand.Columns.Add(new GridColumn() { FieldName = nameof(Product.OrderDate) });var pricingBand = new GridControlBand();
pricingBand.Header = "Pricing";
pricingBand.Columns.Add(new GridColumn() { FieldName = nameof(Product.UnitPrice) });
pricingBand.Columns.Add(new GridColumn() { FieldName = nameof(Product.Quantity) });// Add bands to the GridControl:
grid.Bands.Add(productBand);
grid.Bands.Add(orderBand);
grid.Bands.Add(pricingBand);
VB.NET
Dim productBand = New GridControlBand()
productBand.Header = "Product"
productBand.Columns.Add(New GridColumn() With {
.FieldName = NameOf(Product.ProductName)
})
Dim orderBand = New GridControlBand()
orderBand.Header = "Order Info"
orderBand.Columns.Add(New GridColumn() With {
.FieldName = NameOf(Product.Country)
})
orderBand.Columns.Add(New GridColumn() With {
.FieldName = NameOf(Product.City)
})
orderBand.Columns.Add(New GridColumn() With {
.FieldName = NameOf(Product.OrderDate)
})
Dim pricingBand = New GridControlBand()
pricingBand.Header = "Pricing"
pricingBand.Columns.Add(New GridColumn() With {
.FieldName = NameOf(Product.UnitPrice)
})
pricingBand.Columns.Add(New GridColumn() With {
.FieldName = NameOf(Product.Quantity)
})
grid.Bands.Add(productBand)
grid.Bands.Add(orderBand)
grid.Bands.Add(pricingBand)
使用数据注释属性
您可以使用数据注释属性将网格列分组为栏(Bands):
1. 将DisplayAttribute应用于数据源中的所有字段。
2. 使用DisplayAttribute.GroupName属性来指定栏(Bands)的标题。
3. 将DataControlBase.EnableSmartColumnsGeneration属性设置为true,来根据数据注释属性生成列。
XAML
<dxg:GridControl ItemsSource="{Binding Source}"
AutoGenerateColumns="AddNew"
EnableSmartColumnsGeneration="True">
<!-- ... -->
</dxg:GridControl>
C#
using System.ComponentModel.DataAnnotations;
// ...public class Product {
[Display(GroupName = "Product")]
public string ProductName { get; set; }
[Display(GroupName = "Order Info")]
public string Country { get; set; }
[Display(GroupName = "Order Info")]
public string City { get; set; }
[Display(GroupName = "Pricing")]
public double UnitPrice { get; set; }
[Display(GroupName = "Pricing")]
public int Quantity { get; set; }
[Display(GroupName = "Order Info")]
public DateTime OrderDate { get; set; }
}
VB.NET
Imports System.ComponentModel.DataAnnotations
' ...Public Class Product
<Display(GroupName:="Product")>
Public Property ProductName As String
<Display(GroupName:="Order Info")>
Public Property Country As String
<Display(GroupName:="Order Info")>
Public Property City As String
<Display(GroupName:="Pricing")>
Public Property UnitPrice As Double
<Display(GroupName:="Pricing")>
Public Property Quantity As Integer
<Display(GroupName:="Order Info")>
Public Property OrderDate As DateTime
End Class
绑定到没有GroupName属性的字段的列显示在第一个栏(Bands)中。
