估计你用的是客户端的checkbox，迹斗参考下面的代码吧，肯定可以的。
Page:
<asp:TemplateField HeaderText="选择" >
<ItemTemplate>
<asp:CheckBox ID="chk" runat="server" />
</ItemTemplate>吵州姿升绝
<ItemStyle Width="20px" />
</asp:TemplateField>
CS:
for (int i = 0; i < gvData.Rows.Count; i++)
{
if (((CheckBox)gvData.Rows[i].FindControl("chk")).Checked)
{
pr_no = pr_no + ",'" + gvData.DataKeys[i]["pr_no"].ToString() + "'";
num = num + 1;
}
}
