C# 在网格视图中引用单元格中的文本框

因此，我在视图prop中使用

GridView

制作了一个

ListView

：

<ListView Grid.Row="1" Name="TicketListView" Margin="20,5,20,5">
        <ListView.View>
            <GridView>
                <GridViewColumn Header="Owned" DisplayMemberBinding="{Binding Owned}"/>
                <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
                <GridViewColumn Header="Price" DisplayMemberBinding="{Binding Price, ConverterCulture='en-US', StringFormat={}{0:C2}}"/>
                <GridViewColumn Header="Amount">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBox MinWidth="20" TextAlignment="Center" Margin="5" Text="{Binding Bought, Mode=TwoWay, UpdateSourceTrigger=LostFocus}" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
            </GridView>
        </ListView.View>                
        ...
</ListView>

...

在这个列表视图中选择项目时，我想重点关注特定的

文本框

，这样您就不必点击

文本框

来写，而是可以点击项目（行）并开始更改其值。希望你能理解

这是可能的，还是我应该用另一种方式执行此列表？

关于listitem changed事件 做

---

您可以处理

ListViewItem

的

PreviewMouseLeftButtonDown

事件，并使用

VisualTreeHelper

类获取对

文本框的引用：

<ListView Grid.Row="1" Name="TicketListView">
    <ListView.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <EventSetter Event="PreviewMouseLeftButtonDown" Handler="TicketListView_PreviewMouseLeftButtonDown" />
        </Style>
    </ListView.ItemContainerStyle>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Owned" DisplayMemberBinding="{Binding Owned}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
            <GridViewColumn Header="Price" DisplayMemberBinding="{Binding Price, ConverterCulture='en-US', StringFormat={}{0:C2}}"/>
            <GridViewColumn Header="Amount">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <TextBox MinWidth="20" TextAlignment="Center" Margin="5" Text="{Binding Bought, Mode=TwoWay, UpdateSourceTrigger=LostFocus}" />
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>




private void TicketListView\u PreviewMouseLeftButtonDown（对象发送器，鼠标按钮ventargs e）
{
ListViewItem lvi=作为ListViewItem的发件人；
TextBox TextBox=GetChildOfType（lvi）；
如果（文本框！=null）
{
textBox.Dispatcher.BeginInvoke（新操作（（）=>
{
bool b=textBox.Focus（）；
键盘。焦点（文本框）；
}));
}
}
私有静态T GetChildOfType（DependencyObject depObj），其中T:DependencyObject
{
if（depObj==null）
返回null；
for（int i=0；i
我不知道如何感谢你……你从哪里知道这一切？不客气，但请记住投票选出有用的答案：。我从哪里知道这一切？经验为王：）
