datagridview的一些小技巧

//滚轮定位到选中行

dataGridView1.Rows[i].Cells["Column1"].Selected = true;
dataGridView1.FirstDisplayedScrollingRowIndex = dataGridView1.Rows[i].Index;

//清空选择

dataGridView1.ClearSelection();

//添加一行

int index = dataGridView1.Rows.Add();
dataGridView1.Rows[index].Cells["Column"].Value = "123"; 

//判断datagridviewcheckbox是否被选中

Convert.ToBoolean(dataGridView1.Rows[i].Cells["Column1"].Value) == true

//获取点击行数

int index = dataGridView1.CurrentRow.Index;
