C# 如何使用C读取WPF DataGrid（从数据上下文绑定源）中选中的行单元格值#

这里是wpfwin.xaml中的数据网格。我想收集列表中的“Challan_No”值，但我不能这样做。请帮助我

            <DataGridTextColumn Header="Chalaan ID" Width="Auto" Binding="{Binding   Id, Mode=OneWay}"/>
            <DataGridTextColumn Header="Challan No" Width="Auto" Binding="{Binding Challan_No, Mode=OneWay}" IsReadOnly="True"/>
            <DataGridTextColumn Header="Company" Width="Auto" Binding="{Binding Organization_Name, Mode=OneWay}"/>
            <DataGridTextColumn Header="Client" Width="Auto" Binding="{Binding Organization, Mode=OneWay}"/>
            <DataGridTextColumn Header="Date" Width="Auto" Binding="{Binding Date, Mode=OneWay}"/>

            <DataGridTemplateColumn Header="select"  Width="100" >
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <CheckBox  x:Name="ckselect"  ></CheckBox>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>

            <DataGridTextColumn Header="Chalaan ID" Width="Auto" Binding="{Binding   Id, Mode=OneWay}"/>
            <DataGridTextColumn Header="Challan No" Width="Auto" Binding="{Binding Challan_No, Mode=OneWay}" IsReadOnly="True"/>
            <DataGridTextColumn Header="Company" Width="Auto" Binding="{Binding Organization_Name, Mode=OneWay}"/>
            <DataGridTextColumn Header="Client" Width="Auto" Binding="{Binding Organization, Mode=OneWay}"/>
            <DataGridTextColumn Header="Date" Width="Auto" Binding="{Binding Date, Mode=OneWay}"/>

            <DataGridTemplateColumn Header="select"  Width="100" >
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <CheckBox  x:Name="ckselect"  ></CheckBox>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>

在这里，我尝试了一些代码将其放入.cs页面

            <DataGridTextColumn Header="Chalaan ID" Width="Auto" Binding="{Binding   Id, Mode=OneWay}"/>
            <DataGridTextColumn Header="Challan No" Width="Auto" Binding="{Binding Challan_No, Mode=OneWay}" IsReadOnly="True"/>
            <DataGridTextColumn Header="Company" Width="Auto" Binding="{Binding Organization_Name, Mode=OneWay}"/>
            <DataGridTextColumn Header="Client" Width="Auto" Binding="{Binding Organization, Mode=OneWay}"/>
            <DataGridTextColumn Header="Date" Width="Auto" Binding="{Binding Date, Mode=OneWay}"/>

            <DataGridTemplateColumn Header="select"  Width="100" >
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <CheckBox  x:Name="ckselect"  ></CheckBox>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>

                    ArrayList list = new ArrayList();
                    for (int i = 0; i < myGrid.Items.Count; i++)
                    {
                        CheckBox mycheckbox = myGrid.Columns[5].GetCellContent(myGrid.Items[i]) as CheckBox;
                        if (mycheckbox.IsChecked == true)
                        {
                            int inde = this.myGrid.SelectedIndex;
                            DataRowView drv = (DataRowView)myGrid.Items[inde];
                            object ch = drv[1];
                            list.Add(ch);
                        }
                    }

ArrayList list=new ArrayList（）；
对于（int i=0；i

其中，您的DataGridItems列表表示您的DataGrid绑定到的对象列表。

我认为最好是将IsSelected属性添加到显示的任何类型，然后将该属性双向绑定到复选框列。这样，您只需执行以下操作即可获得选定的元素：

            <DataGridTextColumn Header="Chalaan ID" Width="Auto" Binding="{Binding   Id, Mode=OneWay}"/>
            <DataGridTextColumn Header="Challan No" Width="Auto" Binding="{Binding Challan_No, Mode=OneWay}" IsReadOnly="True"/>
            <DataGridTextColumn Header="Company" Width="Auto" Binding="{Binding Organization_Name, Mode=OneWay}"/>
            <DataGridTextColumn Header="Client" Width="Auto" Binding="{Binding Organization, Mode=OneWay}"/>
            <DataGridTextColumn Header="Date" Width="Auto" Binding="{Binding Date, Mode=OneWay}"/>

我认为最好是将IsSelected属性添加到显示的任何类型，然后将该属性双向绑定到checkbox列。这样，您只需执行以下操作即可获得选定的元素：

            <DataGridTextColumn Header="Chalaan ID" Width="Auto" Binding="{Binding   Id, Mode=OneWay}"/>
            <DataGridTextColumn Header="Challan No" Width="Auto" Binding="{Binding Challan_No, Mode=OneWay}" IsReadOnly="True"/>
            <DataGridTextColumn Header="Company" Width="Auto" Binding="{Binding Organization_Name, Mode=OneWay}"/>
            <DataGridTextColumn Header="Client" Width="Auto" Binding="{Binding Organization, Mode=OneWay}"/>
            <DataGridTextColumn Header="Date" Width="Auto" Binding="{Binding Date, Mode=OneWay}"/>

            <DataGridTemplateColumn Header="select"  Width="100" >
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <CheckBox  x:Name="ckselect"  ></CheckBox>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>

如何启用复选框以选中您的意思是要使DataGridCheckBoxColumn的默认值被选中为真吗？我在我的页面中实现了您的代码，但无法选中它们。您能告诉我您是如何定义DataGrid（Xaml）的吗？Joseph先生，复选框未与数据库（列）绑定，它用于选择与数据库绑定的行DataGrid行。我的代码实现与给定的解决方案相同…如何启用复选框以选中您的意思是使DataGridCheckBoxColumn成为默认值
