在WPF中使用MVVM模式在DataGrid中进行文本框验证 [英] TextBox validation inside a DataGrid using MVVM pattern in WPF

问题描述

大家好，

在wpf项目中，我有一个DataGrid，其中包含TextBox这样的DataGridTemplate列

In a wpf project i have a DataGrid which contains TextBox as DataGridTemplate column like this

 <DataGridTemplateColumn Header="Quantity" Width="100">



     <DataGridTemplateColumn.CellTemplate>



     <DataTemplate>



      <TextBox Text="{Binding Path=Quantity,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged, TargetNullValue=''}" MaxLength="2" IsReadOnly="False"/>



     </DataTemplate>



     </DataGridTemplateColumn.CellTemplate>



</DataGridTemplateColumn>

推荐答案

您需要创建一个实体类，将表的每一列都保存为属性，该属性由inotifypropertychanged和idataerrorinfo接口继承，然后进行检查.

You need to create a entity class that holds each column of your table as property which is inherited by inotifypropertychanged and idataerrorinfo interface then check out this.
