windowsForm开发 如何取tableLayoutPanel中各个单元格上面panel中的控件值

Question

1.背景：
动态创建了一张tableLayoutPanel表，并且在表的单元格里加入了panel控件，然后在各个panel上面加入N个其他控件（例如checkBox控件）
2.问题：
①如何取得tableLayoutPanel表格中各个panel上面的checkBox是否打勾（或者textBox控件中值）？（例如：取表格的（1，1）中panel上面的textBox的值）
②在表格的每个单元格内都有同样的控件，如何取它们的值，参考下图

3.开发语言：
C++/CLR
4.希望：
求大神指教方法，或者具体功能的代码,因为本人是新人，求耐心仔细解答（C++/CLR的代码）
6.简略代码：
下面的函数在InitializeComponent（）中执行
void add(Col_Num,Row_Num)
{
省略
int indexNum = 0;

for ( int i = 0; i < Col_Num; i++ )
{
for ( int j = 0; j < Row_Num; j++ )
{
省略
this->comboBox_display = gcnew ComboBox();

    //
    //comboBox_display
    //
    this->comboBox_display->AddRange(strItem);  //strItem里面为"苹果","梨"
    this->comboBox_display->name = "comboBox_" + indexNum;
    this->comboBox_display->Text = "";
    this->comboBox_display->SelectedIndexChanged += gcnew System::EventHandler(this,&Form,CcomboBox_display_SelectedIndexChanged); //创建触发事件
    ......
    //还有其他几个属性

    省略
            this->panel_display->add(this->comboBox_display);  //把comboBox控件添加到panel上
            this->panel_display->add(this->checkbox_display);  //把checkBox控件添加到panel上
            ........等等
    this->tableLayoutPanel_display->add(this->panel_display,i,j);  //把panel控件添加到对应的表格里面

    省略

    indexNum++;
}

}
}
