Winform实现DataGrid数据上下移动



//上移
private void btnUp_Click(object sender, EventArgs e)
{
int rowIndex =dgvNews.SelectedRows[0].Index;  //得到当前选中行的索引

if (rowIndex == 0)
{
MessageBox.Show("已经是第一行了!");
return;
}

List<string> list = new List<string>();
for (int i = 0; i <dgvNews.Columns.Count; i++)
{
list.Add(dgvNews.SelectedRows[0].Cells[i].Value.ToString());   //把当前选中行的数据存入list数组中
}

for (int j = 0; j <dgvNews.Columns.Count; j++)
{
dgvNews.Rows[rowIndex].Cells[j].Value = dgvNews.Rows[rowIndex - 1].Cells[j].Value;
dgvNews.Rows[rowIndex - 1].Cells[j].Value = list[j].ToString();
}
dgvNews.Rows[rowIndex - 1].Selected = true;
dgvNews.Rows[rowIndex].Selected = false;

}

//下移

private void btnDown_Click(object sender, EventArgs e)

{

int rowIndex = dgvNews.SelectedRows[0].Index; //得到当前选中行的索引

if (rowIndex ==dgvNews.Rows.Count - 1)

{

MessageBox.Show("已经是最后一行了!");

return;

}

List<string> list = new List<string>();

for (int i = 0; i <dgvNews.Columns.Count; i++)

{

list.Add(dgvNews.SelectedRows[0].Cells[i].Value.ToString()); //把当前选中行的数据存入list数组中

}

for (int j = 0; j <dgvNews.Columns.Count; j++)

{

dgvNews.Rows[rowIndex].Cells[j].Value =dgvNews.Rows[rowIndex + 1].Cells[j].Value;

dgvNews.Rows[rowIndex + 1].Cells[j].Value = list[j].ToString();

}

dgvNews.Rows[rowIndex + 1].Selected = true;

dgvNews.Rows[rowIndex].Selected = false;

}

{

list.Add(dgvNews.SelectedRows[0].Cells[i].Value.ToString()); //把当前选中行的数据存入list数组中

}

for (int j = 0; j <dgvNews.Columns.Count; j++)
