wpf DataGridTextColumn重构

本文介绍了wpf DataGridTextColumn重构的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在WPF应用程序中使用了一个DataGrid，该应用程序具有几个（一般为一周的一周）列，这些列仅在其数据索引中有所不同。 xaml的样本如下：

I am using a DataGrid in a WPF app that has several (literally one for each day of the week) columns which differ only in their data index. A sample of the xaml is below.

如何将其重新导入更多的DRY？

How can I refactor this into something more DRY?

样品XAML（七列中的两列）：

SAMPLE XAML (two of seven columns):

<dg:DataGridTextColumn Header="{Binding Source={StaticResource spy}, Path=DataContext[0].EventDate, Converter={StaticResource dateConv}}" CellStyle="{StaticResource DataEntryCellStyle}" Width="60" CanUserResize="False" Binding="{Binding Allocations[0].Amount, Converter={StaticResource amtConv}}" /> <dg:DataGridTextColumn Header="{Binding Source={StaticResource spy}, Path=DataContext[1].EventDate, Converter={StaticResource dateConv}}" CellStyle="{StaticResource DataEntryCellStyle}" Width="60" CanUserResize="False" Binding="{Binding Allocations[1].Amount, Converter={StaticResource amtConv}}" />

编译器抱怨目标类型在构建时不是框架元素

Compiler complains that the target type is not a framework element when building

<Style x:Key="dayOfWeekColumn" TargetType="dg:DataGridTextColumn" > <Setter Property="CanUserResize" Value="False"/> <Setter Property="CanUserSort" Value="False"/> <Setter Property="Width" Value="60" /> <Setter Property="CellStyle" Value="{StaticResource dataEntryGridCellStyle}" /> </Style>

我也看不到任何类似ColumnStyle的东西。在DataGridTextColumn的xaml中，我将设置什么属性？

I don't see anything that looks like a ColumnStyle either. What property would I set this style to in the xaml for the DataGridTextColumn?

推荐答案

也许你可以创建自己的类继承自DataGridTextColumn并添加一个新的DependencyProperty DayIndex（从0到6）。然后在这个课程中，你可以在XAML中进行初始化...

Maybe you can create your own class which inherits from DataGridTextColumn and add a new DependencyProperty DayIndex (from 0 to 6). Then in this class you could to the initialization you're doing in the XAML...

但我不知道这将是一个更好和更可维护的解决方案...

But I'm not sure it will be a really better and more maintainable solution...
