DataGridView DataGridViewCheckBoxColumn编辑时实时触发事件

正常响应CellValueChanged()事件时，当改变checkbox状态时，只有当焦点离开该单元格时才能触发CellValueChanged()事件，

如果要改变checkbox值时实时触发CellValueChanged()事件，需要借用CurrentCellDirtyStateChanged()事件来提交未提交控件的更改。

 

        private void dataGridView1_CurrentCellDirtyStateChanged(object sender, EventArgs e)
        {
            if (dataGridView1.IsCurrentCellDirty)
            {
                dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
            }
        }

这样CellValueChanged()事件就可以随着checkbox的值的改变实时触发；

 

        private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
        {
            if (e.RowIndex >= 0 && e.RowIndex != -1 && !dataGridView1.Rows[e.RowIndex].IsNewRow)
            {
                if (e.ColumnIndex == 7)
                {
                    if ((bool)this.dataGridView1[e.ColumnIndex, e.RowIndex].Value == true)
                    {
                        this.dataGridView1[1, e.RowIndex].Value = 100;
                    }
                    else
                    {
                        this.dataGridView1[1, e.RowIndex].Value = 10;
                    }
                }
            }
            this.toolStripStatusLabel1.Text = e.ColumnIndex.ToString() + "," + e.RowIndex.ToString();
      
        }
