DataGridView 中删除一空行，出错
Gr中可edit ，这样中必然会出现所有可见列都为空值的，我想在某行失去焦点时，进行判断，如空则删除，用dataGridView1_RowLeave事件，但出错信息为:不能在此事件中执行操作。高手请教，该怎做？

private void dataGridView1_RowLeave(object sender, DataGridViewCellEventArgs e)
{
bool flag = true;

for (int i = 0; i < dataGridView1.ColumnCount; i++)
{
if (dataGridView1.Rows[e.RowIndex].Cells[i].Value.ToString ().Trim ()=="")
flag = true;
else

{ flag = false;
break;
}

}
if (flag&&(e.RowIndex!=this.dataGridView1.Rows.Count-1 ))//最后一行，不删
{

try
{
this.dataGridView1.Rows.Remove(this.dataGridView1.Rows[e.RowIndex]);//有问题
//this.dataGridView1.Rows.RemoveAt(e.RowIndex);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString()+"kkk"+e.RowIndex.ToString ());

}

}
}

只是个思路，lz可以试下

C# code

        DataTable dt;        private void Form1_Load(object sender, EventArgs e)        {            dt = new DataTable();            dt.Columns.Add(new DataColumn("id"));            dt.Columns.Add(new DataColumn("name"));            DataRow dr = null;            dr = dt.NewRow();            dr["id"] = "001";            dr["name"] = "Name1";            dt.Rows.Add(dr);            dr = dt.NewRow();            dr["id"] = "002";            dr["name"] = "Name2";            dt.Rows.Add(dr);            dr = dt.NewRow();            dr["id"] = "001";            dr["name"] = "Name1";            dt.Rows.Add(dr);            //dt.TableNewRow += new DataTableNewRowEventHandler(dt_NewTableRow);            dataGridView1.DataSource = dt;        }        bool flag = true;        private void dataGridView1_RowLeave(object sender, DataGridViewCellEventArgs e)        {            if (flag == false)                dt.Rows.RemoveAt(e.RowIndex);            flag = false;        }

应该尽量从客户端控制其写入数据库中的数据的有效性！
