C ++ DataGridView [英] C++ DataGridView

问题描述

我正在尝试将ArrayList绑定到DataGridView，但是在使其正常工作时遇到了问题.我找到了一个C#示例，并尝试将其转换为C ++，但最终得到一个空白的DataGridView.这是我的测试代码:

I'm trying to bind an ArrayList to a DataGridView, and I'm having problems getting it to work correctly.  I found a C# example and I tried to convert it to C++, but I end up with a blank DataGridView.  This is my test code:

       ArrayList ^ list = gcnew ArrayList();
        list-> Add(gcnew Developer("Mahesh"，"Chand"，30，"C#，ASP.NET，Windows Forms"，10))；
        list-> Add(gcnew Developer("Michael"，"Gold"，35，"GDI +，ASP.NET"，15)))；
        list-> Add(gcnew Developer("Bhasker"，"Das"，26，"VB.NET，Web应用程序"，4))；
        list-> Add(gcnew Developer("Ashish"，"Singhal"，24，"ADO.NET，GDI +"，4)))；
        list-> Add(gcnew Developer("Neel"，"Beniwal"，3，"C#，ASP.NET，Windows Forms"，0));
        list-> Add(gcnew Developer("Melanie"，"Talmadge"，25，"Java"，2)))；
        dataGridView1-> DataSource =列表;
        dataGridView1-> Refresh();

        ArrayList^ list = gcnew ArrayList();
        list->Add(gcnew Developer("Mahesh", "Chand", 30, "C#,ASP.NET,Windows Forms", 10)) ;
        list->Add(gcnew Developer("Michael", "Gold", 35, "GDI+, ASP.NET", 15)) ;
        list->Add(gcnew Developer("Bhasker", "Das", 26, "VB.NET, Web Applications", 4)) ;
        list->Add(gcnew Developer("Ashish", "Singhal", 24, "ADO.NET, GDI+", 4)) ;
        list->Add(gcnew Developer("Neel", "Beniwal", 3, "C#,ASP.NET,Windows Forms", 0)) ;
        list->Add(gcnew Developer("Melanie", "Talmadge", 25, "Java", 2)) ;
        dataGridView1->DataSource = list;
        dataGridView1->Refresh();

要在C ++中正常工作，是否需要在C ++中执行其他步骤?

Is there an additional step that needs to happen in C++ for this to work correctly?

 

推荐答案

您是否向网格中添加了列?

did you add columns to the grid?
