从DataGrid中的选定行获取特定单元格的数据WPF C＃ [英] Get data of specific cell from selected row in DataGrid WPF C#

问题描述

我有一个DataGrid，我填充从我的sql数据库的数据。
现在我想从我用复选框选择的行获得一个特定的单元格（第2个单元格）。

I have a DataGrid which I fill with data from my sql database. Now I want to get a specific cell (2nd cell) from the row I selected with a checkbox.

这是我现在的状态：
WPF XAML：

This is what I have now: WPF XAML:

<DataGrid Name="myGrid">
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <CheckBox Checked="CheckBox_Checked"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    <DataGridTextColumn Header="CustomerID" Width="Auto" Binding="{Binding CustomerID}"/>
    <DataGridTextColumn Header="ItemID" Width="Auto" Binding="{Binding ItemID}"/>
<DataGrid>

C＃代码：

private void CheckBox_Checked(object sender, RoutedEventArgs e)
    {
        DataGrid row = (DataGrid)myGrid.SelectedItems[1];
        System.Windows.MessageBox.Show(row);
    }

运行时出现错误：

System.ArgumentOutOfRangeException

System.ArgumentOutOfRangeException

{索引超出范围，必须为非负数且小于the collection.\r\\\
Parameter name：index}

{"Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index"}

我做错了什么？我必须使用另一种方法来获得我想要的单元格。

What am I doing wrong? Do I have to use another approach to get the cell I want?

推荐答案

我终于找到了！很简单。

I finally found it! Very simple.

DataRowView drv = (DataRowView)myGrid.SelectedItem; 
String result = (drv["CustomerID"]).ToString(); 
MessageBox.Show(result);
