我们的想法是用户在数据库中搜索记录。当记录返回时，他们可以单击记录以从anther表返回更多信息。感谢

这是我的代码：这包含我的c＃logic。

Answer 1

将gridview的DataKeys属性设置为数据集中的主键字段

DataKeys="<YourPrimaryKeyField>"

将网格视图的OnSelectedIndexChanged属性设置为gridView_SelectedIndexChanged

在代码中添加一个方法来处理事件。

 protected void gridView_SelectedIndexChanged(object sender, GridViewSelectEventArgs e)
    {

        string key = gridView.DataKeys[e.NewSelectedIndex].Value.ToString();

        //Call your GetData function and pass in this value as a parameter
         GetSpecificCustomerData(key) ;
    }

Answer 2

U最好使用AutoGenerateColumns = false，BoundFields / Templatefields和rowcommand事件。

如何从gridview中的行中选择一个值以用作新存储过程中的变量？
