DataGridViewCheckBoxCell后台获取勾选

[回头是岸]

statusViewText.Text = "数据正在处理中.....";
int count = Convert.ToInt32(dgvLeaveInfo.Rows.Count.ToString());
for (int i = 0; i < count; i++)
{
DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)dgvLeaveInfo.Rows[i].Cells["gvChecked"];
if (dgvLeaveInfo.Rows[i].Cells["gvChecked"].Value !="" )
{
if ((Boolean)checkCell.Value) //删除被选择的数据行
{

MAttendance attendance = (MAttendance)_CurrentMAttendance[i];
int typeId = attendance.TypeId;
DateTime beginTime = Convert.ToDateTime(attendance.BegTime);

message = client.DeletAbsenteeismInfo(typeId, beginTime, AttendanceMonth);


if (message.IsSuccess)
{
_CurrentMAttendance.Remove(attendance);
}

statusViewText.Text = "数据处理完毕";
}

}
}
这里dgvLeaveInfo.Rows[i].Cells["gvChecked"].Value !=""或dgvLeaveInfo.Rows[i].Cells["gvChecked"].Value !=null都报错
这是怎么回事？

foreach (DataGridViewRow dr in this.dataGridView1.Rows)
{
DataGridViewCheckBoxCell cbx = (DataGridViewCheckBoxCell)dr.Cells[0];
if (!(bool)cbx.FormattedValue)
{

}
}

[xiongcaoyuanlang]

foreach (DataGridViewRow dr in this.dataGridView1.Rows)
{
DataGridViewCheckBoxCell cbx = (DataGridViewCheckBoxCell)dr.FindControl["checkbox"];
if (cbx.checked)
{

}
}

1楼的我试了是对的
我调试了有几次 dgvLeaveInfo.Rows[i].Cells["gvChecked"].Value值就是true
那我这个dgvLeaveInfo.Rows[i].Cells["gvChecked"].Value为什么不对呢？能告诉我吗？

foreach (DataGridViewRow dr in this.dataGridView1.Rows) 看这句话！！！

。。这个简单，前天做了


循环你的dataGridView.Rows()
