对girdview中的复选框进行勾选，如何在函数中更改对应的checked的值
------解决方案--------------------------------------------------------
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
if (cbox.Checked == true)
{
}
}
------解决方案--------------------------------------------------------
for (int i = 0; i < GridView1.Rows.Count; i++)
{
CheckBox cb = GridView1.Rows[i].FindControl("CheckBox1") as CheckBox;
if (cb != null)
{
if (cb.Checked)
被勾选;
else 没有被勾选;
}
}
