那这句是什么意思呢
程序集:System.Web（在 system.web.dll 中）属性值
一个 GridViewRowCollection，包含 GridView 控件中的所有数据行。Rows 属性（集合）用来存储 GridView 控件中的数据行。GridView 控件自动填充 Rows 集合，方法是为数据源中的每条记录创建一个 GridViewRow 对象，然后将每个对象添加到该集合。此属性通常用于访问控件中的特定行或者循环访问整个行集合。注意
只有其 RowType 属性设置为 DataControlRowType.DataRow 的行才会存储在 Rows 集合中。该集合中不包括表示标题行、脚注行和页导航行的 GridViewRow 对象。示例
下面的代码示例演示如何使用 Rows 集合访问 GridView 控件中正在编辑的行。在行被更新之后，会显示一条消息指示更新成功。
<%@ Page language="C#" %><script runat="server">
void CustomersGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
// Clear the message label when the user enters edit mode.
if (e.CommandName == "Edit")
{
Message.Text = "";
}
} void CustomersGridView_RowUpdated(Object sender, GridViewUpdatedEventArgs e)
{
// The update operation was successful. Retrieve the row being edited.
int index = CustomersGridView.EditIndex;
GridViewRow row = CustomersGridView.Rows[index];
// Notify the user that the update was successful.
Message.Text = "Updated record " + row.Cells[1].Text + ".";
} void CustomersGridView_RowCancelingEdit(Object sender, GridViewCancelEditEventArgs e)
{
// The update operation was canceled. Display the appropriate message.
Message.Text = "Update operation canceled.";
}</script><html>
