绑定数据


你可以将GridControl绑定到任何实现IEnumerable接口的对象或它的下级对象(例如,IList,ICollection)。要将控件绑定到数据上,你应该为网格的DataControlBase.ItemsSource属性分配一个数据源。


<Window xmlns:dxg="http://schemas.devexpress.com/winfx/2008/xaml/grid" ...>
    <dxg:GridControl ItemsSource="{Binding Customers}" AutoGenerateColumns="AddNew"/>
</Window>

在后台的数据绑定中,grid.ItemsSource = 数据集是通用的,只是在前端xml表达式上有明显区别。

将Grid绑定到MS Access数据库


<Window x:Class="DXGrid_BindingToMSAccessDb.Window1" 
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:dxg="http://schemas.devexpress.com/winfx/2008/xaml/grid" 
        Title="Window1" Height="291" Width="518">
    <Grid>
        <dxg:GridControl x:Name="grid" AutoGenerateColumns="AddNew">
            <dxg:GridControl.View>
                <dxg:TableView />
            </dxg:GridControl.View>
        </dxg:GridControl>
    </Grid>
</Window>
将Grid绑定到一个XML文件



<Window x:Class="DXGrid_BindingToXML.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        xmlns:dxg="http://schemas.devexpress.com/winfx/2008/xaml/grid"
        Title="Window1">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="30" />
        </Grid.RowDefinitions>

        <dxg:GridControl 
            x:Name="grid" 
            VerticalAlignment="Top">
            <dxg:GridControl.Columns>
                <dxg:GridColumn FieldName="FirstName" />
                <dxg:GridColumn FieldName="LastName" />
                <dxg:GridColumn FieldName="Company" />
                <dxg:GridColumn FieldName="City" />
            </dxg:GridControl.Columns>
            <dxg:GridControl.View>
                <dxg:TableView AutoWidth="True" />
            </dxg:GridControl.View>
        </dxg:GridControl>
        <Button Margin="5" Grid.Row="1" Click="Button_Click" 
                VerticalAlignment="Bottom" HorizontalAlignment="Left" 
                Content="Post Data to an XML File"/>
    </Grid>
</Window>
显示非绑定数据



<Window x:Class="DXGrid_UnboundColumns.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:dxg="http://schemas.devexpress.com/winfx/2008/xaml/grid"
        xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors"
        Title="Window1"
        Height="300"
        Width="552">
    <Grid>
        <dxg:GridControl x:Name="grid" CustomUnboundColumnData="grid_CustomUnboundColumnData">
            <dxg:GridControl.Columns>
                <dxg:GridColumn FieldName="ProductName" />
                <dxg:GridColumn FieldName="UnitPrice">
                    <dxg:GridColumn.EditSettings>
                        <dxe:TextEditSettings DisplayFormat="c2" />
                    </dxg:GridColumn.EditSettings>
                </dxg:GridColumn>
                <dxg:GridColumn FieldName="UnitsOnOrder" />
                <dxg:GridColumn FieldName="Total" UnboundType="Boolean" ReadOnly="True">
                    <dxg:GridColumn.EditSettings>
                        <dxe:TextEditSettings DisplayFormat="c2" />
                    </dxg:GridColumn.EditSettings>
                </dxg:GridColumn>
            </dxg:GridControl.Columns>
            <dxg:GridControl.View>
                <dxg:TableView AutoWidth="True"/>
            </dxg:GridControl.View>
        </dxg:GridControl>
    </Grid>
</Window>
