DevExpress中自定义CellTemplate数据绑定不显示的问题

来源：互联网发布：淘宝上的驱鼠器编辑：程序博客网时间：2024/04/29 03:03

定义Student类，其中有布尔值属性IsNormal和IsLate，View中使用DevExpress的GridControl，将两个布尔值放入一个单元格中，以RadioButton显示，需要自定义CellTemplate，但是当进行RadioButton的Checked属性和两个布尔值进行绑定的时候总是出错，原来是数据并没有绑过去，正确的绑定方式应该是,注意

Binding RowData.Row.IsNormal

                <dxg:GridControl  Name="datagrid" AutoGenerateColumns="None" ShowBorder="False" CurrentItem="{Binding CurrentItem,Mode=TwoWay}" SelectedItem="{Binding SelectedItem,Mode=TwoWay}"                           ItemsSource="{Binding Students}">                    <dxg:GridControl.View>                        <dxg:TableView AutoWidth="True" AllowEditing="True"/>                    </dxg:GridControl.View>                    <dxg:GridControl.Columns>                        <dxg:GridColumn Header="学号" Binding="{Binding Sid,Mode=TwoWay}"/>                        <dxg:GridColumn
