如何从Listview / Gridview WPF中提取某些数据单元格

Question

嗨，请记住，我是WPF新手，我使用的是一个返回gridlist[]的WebService ，它会自动填充Gridview 。 这是WebService ：

C＃：

WebService.Contacts Contact = new WebService.Contacts();
grdGetGroup.ItemsSource = Contact.GetGroups(Username, Password);

这是我的XAML ：

<ListView x:Name="grdGetGroup"
          Margin="560,34,128,48"
          FontSize="13"
          BorderBrush="#FFF01F1F"
          Foreground="#FFF01F1F"
          SelectedIndex="1"
          FontFamily="/WPF Working Experimenet;component/Font/#B Nazanin">
    <ListView.View>
        <GridView>
            <GridViewColumn x:Name="GridID"
                            Header="ID"
                            Width="50"
                            DisplayMemberBinding="{Binding GroupID}"
                            FrameworkElement.FlowDirection="RightToLeft" />
            <GridViewColumn Header="Group Name"
                            Width="85
                                                            "
                            DisplayMemberBinding="{Binding GroupName}"
                            FrameworkElement.FlowDirection="RightToLeft" />
            <GridViewColumn Header="Numbers"
                            Width="60"
                            DisplayMemberBinding="{Binding ContactCount}"
                            FrameworkElement.FlowDirection="RightToLeft" />
            <GridViewColumn Header="Access"
                            Width="60"
                            DisplayMemberBinding="{Binding ShowToChild}"
                            FrameworkElement.FlowDirection="RightToLeft" />
            <GridViewColumn Header="Description"

                            FrameworkElement.FlowDirection="RightToLeft" />
            <GridViewColumn Header=""
                            Width="60"

            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>

如果您已经注意到，我也会自动为Gridview中的每一行设置2个button ，现在这是我的问题，如何在GridviewColumn x:Name"GridID"提取Data ？ 并将其传递给同一行的Button Click Event （哪个method采用Data作为输入）

如果我理解/猜对了，那么每一行上都有一个gridList项。

如果我不理解/猜对了，每个gridList都有一个GroupID属性。
如果错了，请纠正我。

在WPF中，在DataGrid中，每行都有一个DataContext属性，该属性保存该行的数据：

void btnRemoveGroup_Click( Object sender, EventArgs args)
{
    var fxElt = sender as FrameworkElement;
    var lineData = fxElt.DataContext as gridlist;
    int groupID = lineData .GroupID;
}

告诉我它是否有效。 问候
