在GridView里面添加CheckBox，如何实现哪一行被选中

一：添加CheckBox

<asp:GridView>

<Columns>

<asp:TemplateField HeaderText="选择">

<ItemStyle HorizontalAlign="Center" Height="35px" Width="720px"/>

<ItemTemplate>

<asp:CheckBox ID="CheckBox" runat="server" ></asp:CheckBox>

</ItemTemplate>

</asp:TemplateField>

<asp:BoundField DataField="Code" HeaderText="学号" SortExpression="Code">

<ItemStyle HorizontalAlign="Center" Height="35px" Width="720px"/>

</asp:BoundField>

<asp:BoundField DataField="Name" HeaderText="姓名">

<ItemStyle HorizontalAlign="Center" Height="35px" Width="720px"/>

</asp:BoundField>

<asp:BoundField DataField="SchoolName" HeaderText="所在学校">

<ItemStyle HorizontalAlign="Center" Height="35px" Width="720px"/>

</asp:BoundField>

<asp:BoundField DataField="Email" HeaderText="E-mail">

<ItemStyle HorizontalAlign="Center" Height="35px" Width="720px"/>

</asp:BoundField>

</Columns>

</asp:GridView>

二：查看哪一行的CheckBox被选中

foreach(GridViewRow row in this.StudentGridView.Rows)

{

Control ctrl = row.FindControl("CheckBox");

if ((ctrl as CheckBox).Checked)

{

TableCellCollection cell = row.Cells;

string studentCode = cell[1].Text;

}

}
