将数组值填充到行而不是列中

  • 772

ListView能否将值填充到行而不是列中？

情况如下：我需要填写如图所示的值：

桌子

例如，初始条件为0.01，它以边界1.1结束，这里是我的i1，i2，i3，i4，我需要填写字符串中的值（从初始到最终）。

我已经知道如何通过循环添加列：

int kolst =10;
listView1->Columns->Add("Начальные условия", -2, HorizontalAlignment::Right);
for(int i = 1;i<kolst+1;i++)
 {
  listView1->Columns->Add("i + " + i, -2, HorizontalAlignment::Left);//Нумерация столбцов
 }
listView1->Columns->Add("Граничные условия", -2, HorizontalAlignment::Left);

但是如何精确地按行填写值并不清楚。我根据需要填写了初始条件和边界条件及其表达式，它只是将数组中的表达式填入一行，而不是填入列（i1，i2，i3，i4）。即在每个i1,i2下，我应该有一个数组值。如何才能做到这一点？

我尝试做的是：我在循环中进行了替换Items.Add,Columns.Add，但未显示该行。

    不要忘记替换开始和结束列的值（InitialValue & RangeBound）：

    public ref class Form1 : public System::Windows::Forms::Form
{
public:
    Form1(void)
    {
        InitializeComponent();
    }

   System::Windows::Forms::ListView^ listView1;

    void InitializeComponent(void)
    {
        int kolst = 10;

        this->listView1 = (gcnew System::Windows::Forms::ListView());
        this->SuspendLayout();

        this->listView1->Columns->Add("Начальные условия", -2, HorizontalAlignment::Right);
        for(int i = 1;i<kolst+1;i++)
        {
            this->listView1->Columns->Add("i + " + i, -2, HorizontalAlignment::Left);//Нумерация столбцов
        }
        this->listView1->Columns->Add("Граничные условия", -2, HorizontalAlignment::Left);

        System::Windows::Forms::ListViewItem^  listViewItemInitial = (gcnew System::Windows::Forms::ListViewItem(L"InitialValue"));
        System::Windows::Forms::ListViewItem^  listViewItem1 = (gcnew System::Windows::Forms::ListViewItem(L"q1"));
        System::Windows::Forms::ListViewItem^  listViewItem2 = (gcnew System::Windows::Forms::ListViewItem(L"q2"));
        System::Windows::Forms::ListViewItem^  listViewItem3 = (gcnew System::Windows::Forms::ListViewItem(L"q3"));
        System::Windows::Forms::ListViewItem^  listViewItem4 = (gcnew System::Windows::Forms::ListViewItem(L"q4"));
        System::Windows::Forms::ListViewItem^  listViewItem5 = (gcnew System::Windows::Forms::ListViewItem(L"q5"));
        System::Windows::Forms::ListViewItem^  listViewItem6 = (gcnew System::Windows::Forms::ListViewItem(L"q6"));
        System::Windows::Forms::ListViewItem^  listViewItem7 = (gcnew System::Windows::Forms::ListViewItem(L"q7"));
        System::Windows::Forms::ListViewItem^  listViewItem8 = (gcnew System::Windows::Forms::ListViewItem(L"q8"));
        System::Windows::Forms::ListViewItem^  listViewItemRangeBound = (gcnew System::Windows::Forms::ListViewItem(L"RangeBound"));

        this->listView1->Items->AddRange(gcnew cli::array< System::Windows::Forms::ListViewItem^  >(10) {listViewItemInitial, listViewItem1, listViewItem2, 
            listViewItem3, listViewItem4, listViewItem5, listViewItem6, listViewItem7, listViewItem8, listViewItemRangeBound});
    }
}
