datagridview事件

Question

请问我在datagridview裡添加了一datagridviewcheckboxcolumn列(當然還有其它很多列),我如何判斷用戶點擊了datagridviewcheckboxcolumn這列裡的內容,并且值也改變了?我應該使用哪個事件?謝謝.

Answer 1

        private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            this.dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
            MessageBox.Show(this.dataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString());
        }

Answer 2

CellContentClick
或者
ValueChange

Answer 3

 private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
        {
            if (dataGridView1.DataSource == null)
            {
                return;
            }
            if (this.dataGridView1.Columns[this.dataGridView1.CurrentCell.ColumnIndex].Name == "colIsNeed")
            {
                DataGridViewCheckBoxCell oCell = this.dgTest.CurrentCell as DataGridViewCheckBoxCell;
                if ((bool)oCell.Value)
                {
                    dataGridView1["colNumber",e.RowIndex].Value = e.RowIndex.ToString() ;
                }
                else
                {
                    dataGridView1["colNumber", e.RowIndex].Value = "";
                }
            }
        }
参考

Answer 4

记得checkbox可以直接绑定boolean类型数据，不用加什么，

Answer 5

楼上正解，直接绑定bool类型，用CellValueChanged事件判断点击

Answer 6

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.RowIndex > -1 && e.ColumnIndex > -1)
            {
                bool value = (bool)dataGridView1[e.ColumnIndex, e.RowIndex].Value;
                dataGridView1[e.ColumnIndex, e.RowIndex].Value = !value;
            }
        }
