为了满足各种开发需求,我们需要为DataForm制定不同的模板。本文将为大家介绍如何配置DataForm四个部分的模板——头模板(HeaderTemplate)、编辑项模板(EditTemplate)、新增项模板(NewItemTemplate)以及只读模板(ReadOnlyTemplate)。
预备工作
打开MainPage.xaml文件,在UserControl标签中添加如下命名空间:
xmlns:dataFormToolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data.DataForm.Toolkit"
1)头模板的配置
配置格式如下:
<dataFormToolkit:DataForm.HeaderTemplate>
<DataTemplate>
<!--这里添加需要配置的控件-->
</DataTemplate>
</dataFormToolkit:DataForm.HeaderTemplate>
2)编辑项模板的配置
配置格式如下:
<dataFormToolkit:DataForm.EditTemplate>
<DataTemplate>
<!--这里添加需要配置的控件-->
</DataTemplate>
</dataFormToolkit:DataForm.EditTemplate>
3)新增项模板的配置
配置格式如下:
<dataFormToolkit:DataForm.NewItemTemplate>
<DataTemplate>
<!--这里添加需要配置的控件-->
</DataTemplate>
</dataFormToolkit:DataForm.NewItemTemplate>
4)只读模板的配置
配置格式如下:
<dataFormToolkit:DataForm.ReadOnlyTemplate>
<DataTemplate>
<!--这里添加需要配置的控件-->
</DataTemplate>
</dataFormToolkit:DataForm.ReadOnlyTemplate>

详细的说明在代码中给出。
