首先
using System;
然後,設定全選button,選中所有的checkbox
private void selectAll_Click(object sender, EventArgs e) { //遍歷datagridview中的每一行,判斷是否選中,若為選中,則選中 for (int i = 0; i < dataGridView1.Rows.Count; i++) { if ((Convert.ToBoolean(dataGridView1.Rows[i].Cells[0].Value) == false)) { dataGridView1.Rows[i].Cells[0].Value = "True"; } else continue; } }
接著,設定取消全選button,取消選中的所有checkbox
private void cancelAll_Click(object sender, EventArgs e) { for (int i = 0; i < dataGridView1.Rows.Count; i++) { if ((Convert.ToBoolean(dataGridView1.Rows[i].Cells[0].Value) == true)) { dataGridView1.Rows[i].Cells[0].Value = "False"; } else continue; } }
