Question

我正在使用CellClick事件，并希望更新网格上的另一个复选框。示例： - 包含“添加”和“删除”列的两列。用户单击“添加”，系统将检查是否也未选中“删除”复选框。如果选中删除 ------将Delete设置为false

换句话说，不能同时检查同一行的复选框“添加”和“删除”。

我正在使用......

private void customersDataGridView_CellClick(object sender, DataGridViewCellEventArgs e)

如何通过名称“添加”获取当前单元格的值。
如何通过名称“删除”获取其他单元格的值。上面的过程是翻转/翻转。

如果我是新手如何以对象的形式访问单元格，我应该能够完成其余的工作。

我一直在寻找使用cmbBox = e.Control as ComboBox的例子，但这不起作用：（

这有效......

private void customersDataGridView_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.ColumnIndex >= 0 && e.RowIndex >= 0)
    {   
        //Set a var that determined whether or not the checkbox is selected       
        bool selected = (bool)this.customersDataGridView[e.ColumnIndex, e.RowIndex].Selected;
        //Do the flip-flop here  
        const int add = 4;
        const int delete = 5;
        switch (e.ColumnIndex)
        {
            //If the checkbox in the Add column changed,
            //  flip the value of the corresponding Delete column           
            case add:
                this.customersDataGridView[delete, e.RowIndex].Value = !selected;
                break;
            //If the checkbox in the Delete column changed, 
            //  flop the value of the corresponding Add column       
            case delete:
                this.customersDataGridView[add, e.RowIndex].Value = !selected;
                break;
        }
    }
}

不需要dataGridView1_CellMouseUp

尝试使用CellValueChanged事件而不是CellClick事件。下面的处理程序将根据其对应复选框的相反值（即同一行中的复选框）设置复选框的值。

private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
    if (e.ColumnIndex >= 0 && e.RowIndex >= 0)
    {
        //Set a var that determined whether or not the checkbox is selected
        bool selected = (bool)this.dataGridView1[e.ColumnIndex, e.RowIndex].Value;

        //Do the flip-flop here
        switch (e.ColumnIndex)
        {
            //If the checkbox in the Add column changed, flip the value of the corresponding Delete column
            case 0:
                this.dataGridView1[1, e.RowIndex].Value = !selected;
                break;
            //If the checkbox in the Delete column changed, flop the value of the corresponding Add column
            case 1:
                this.dataGridView1[0, e.RowIndex].Value = !selected;
                break;
        }
    }
}

//You may need to do something goofy like this to update the DataGrid 
private void dataGridView1_CellMouseUp(object sender, DataGridViewCellMouseEventArgs e)
{

    if (e.ColumnIndex >= 0 && e.RowIndex >= 0)
    {
        this.dataGridView1.EndEdit();
    }
}
