Question

如何通过单击按钮更改c＃中datagridview的当前行？

Answer 1

如果您的意思是更改选定的行索引，则应该有效：

private void button_Click(object sender, EventArgs e)
{
    grid.ClearSelection();
    // Select the third row.
    grid.Rows[2].Selected = true;
}

如果你想交换行（例如，在第1行和第3行交换数据），这里有一个选项：

int currentRowIndex = 0;
int newRowIndex = 2;

var currentRow = grid.Rows[currentRowIndex];
var rowToReplace = grid.Rows[newRowIndex];

grid.Rows.Remove(currentRow);
grid.Rows.Remove(rowToReplace);
grid.Rows.Insert(currentRowIndex, rowToReplace);
grid.Rows.Insert(newRowIndex, currentRow);

此外，如果您想移动选择箭头并且您的行不可见，则：

grid.FirstDisplayedScrollingRowIndex = grid.Rows[2].Index;
DataGgridridView1.Refresh()
grid.CurrentCell = grid.Rows[2].Cells(1) // need to ensure that this is an existing, visible cell

grid.Rows[2].Selected = True
