c# datagridview表格控件常用操作

private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
if (e.Button == MouseButtons.Right){
if (e.RowIndex >= 0){
//若行已是选中状态就不再进行设置
if (dataGridView1.Rows[e.RowIndex].Selected == false)

}

//只选中一行时设置活动单元格
if (dataGridView1.SelectedRows.Count == 1){

}

if (isexport == "已导出")
{
//弹出操作菜单
contextMenuStrip1.Show(MousePosition.X, MousePosition.Y);
}
}

}

}
}
}
