无法从datagrid检索已检查的行 [英] Unable to retrieve the checked rows from datagrid

问题描述

我正在尝试使用WPF创建一个简单的Datagrid，以便每行都有一个复选框。我在检索数据时遇到了困难。我只得到1个结果。我可以在下面的XAML中修复什么

< DataGrid x：Name =detailsx：Uid =MyDataGridAutoGenerateColumns =FalseAlternationCount =1SelectionMode =SingleIsReadOnly =TrueHeadersVisibility =ColumnMargin =0,0,10,2Horizo​​ntalAlignment =RightWidth =410Grid.Column =1Grid.Row =1> ; 
< DataGrid.Columns> 
< DataGridTemplateColumn> 
< DataGridTemplateColumn.Header> 
< CheckBox Content =全选x：Name =headerCheckBox/> 
< /DataGridTemplateColumn.Header> 
< DataGridTemplateColumn.CellTemplate> 
< DataTemplate> 
< CheckBox Name =chkDiscontinueIsChecked ={Binding Path = IsChecked，ElementName = headerCheckBox，Mode = OneWay}Margin =45 2 0 0/> 
< / DataTemplate> 
< /DataGridTemplateColumn.CellTemplate> 
< / DataGridTemplateColumn> 
< DataGridTextColumn Binding ={Binding Path = file_name}Header =File NameWidth =2 *IsReadOnly =True/> 
< DataGridTextColumn Binding ={Binding Path = file_path}Header =File PathWidth =0.9 */> 
< /DataGrid.Columns> < /数据网格>

I am trying to create a simple Datagrid using WPF such that each row has a checkbox. I am having a tough time while retrieving the data. I am getting only 1 result. What can I fix in the below XAML

<DataGrid x:Name="details" x:Uid="MyDataGrid" AutoGenerateColumns="False" AlternationCount="1" SelectionMode="Single" IsReadOnly="True" HeadersVisibility="Column" Margin="0,0,10,2" HorizontalAlignment="Right" Width="410" Grid.Column="1" Grid.Row="1" >
           <DataGrid.Columns>
               <DataGridTemplateColumn>
                   <DataGridTemplateColumn.Header>
                       <CheckBox Content=" Select All" x:Name="headerCheckBox" />
                   </DataGridTemplateColumn.Header>
                   <DataGridTemplateColumn.CellTemplate>
                       <DataTemplate>
                           <CheckBox Name="chkDiscontinue"  IsChecked="{Binding Path=IsChecked,ElementName=headerCheckBox,Mode=OneWay}"   Margin="45 2 0 0"  />
                       </DataTemplate>
                   </DataGridTemplateColumn.CellTemplate>
               </DataGridTemplateColumn>
               <DataGridTextColumn Binding="{Binding Path=file_name}" Header="File Name" Width="2*" IsReadOnly="True" />
               <DataGridTextColumn Binding="{Binding Path=file_path}" Header="File Path" Width="0.9*"/>
          </DataGrid.Columns> </DataGrid>
