protected void CheckBox2_CheckedChanged(object sender, EventArgs e)
{
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
if (CheckBox2.Checked == true)
{
cbox.Checked = true;
}
else
{
cbox.Checked = false;
}
}
}
可以实现选择，但是如何能做到在选择行后，在页脚处显示选择行的合计呢？谢谢！

同样用查找控件的方法，把当前所选择行的数据合计起来放在页脚处

if (CheckBox2.Checked == true)
{
cbox.Checked = true;
count+=int.Parse(e.Row.Cells[1].Text);
}
