在VB.NET中绘制三个用户控件网格 [英] Draw three grids of user controls in VB.NET

问题描述

我有一个25x25大小的用户控件，我想将其复制到三个单独的10x10网格中，可以更改其在表单上的位置. 我正在进行大流行病模拟，因此三个网格代表三个国家，我将根据网格正方形的感染状态更改用户控件的颜色.

I have one user control of size 25x25 and I want to duplicate it into three separate 10x10 grids which I can change the location of on my form. I'm making a pandemic simulation so the three grids represent the three countries and I will change the colour of the user control depending on the infection status of the grid square.

我已经使用了很长时间，但是我无法使用它，当我使用Me.Controls.Add(UserControl)时，它会覆盖前一个，而我只剩下一个用户控件表格.

I've been playing around with this for a long time but I cannot get it to work, when I use Me.Controls.Add(UserControl) it overwrites the previous one and I'm left with only one user control on the form.

任何帮助表示感谢，谢谢.

Any help appreciated, thanks.

推荐答案

下面是一种将创建网格的方法，您可以将任意控件放入此网格"的单元"中. 要运行此代码，请将此代码粘贴到任何按钮处理程序中，它将完成所需的一切. 我不知道这是否是确切的解决方案，但您可能会从中得到一些帮助.如果您可以在不同的状态下模拟屏幕，这将很有帮助，这样我们就会了解您的实际需求.

Below is a method that will create grid and you can place arbitrary controls into "cells" of this "grid". To run this, paste this code into any button handler and it will do everything it needs. I don't know if this is exact solution but you may get something out of it. It would be helpful if you could make a mock of your screen in different states, so we understand what you actually want.

在某些按钮处理程序上调用方法DoAGrid:

Call method DoAGrid on some button handler:

 DoAGrid(bool.Parse(_txtTest.Text)); // type true or false in txt

方法

private void DoAGrid(bool isTest)
{

        const int size = 30; // I give 2 for controll padding
        const int padding = 20; // x and y starting padding
        Point[,] grid = new Point[10,10]; // x and y of each control


        List<Control> btns = null; 
        if (isTest) btns  = new List<Control>(100);

        for (int x = 1; x < 11; x++)
        {
            for (int y = 1; y < 11; y++)
            {
                grid[x - 1, y - 1] = new Point(padding + x*size - 30 - 1,  padding + y*size - 30 - 1); // 30 - 1 --> size + 2
                if (isTest)
                { // this test will add all avail buttons so you can see how grid is formed
                    Button b = new Button();
                    b.Size = new Size(size, size);
                    b.Text = "B";
                    b.Location = grid[x - 1, y - 1];
                    btns.Add(b);
                }

            }
        }

        Form f = new Form();
        f.Size = new Size(1000, 1000);

        if (isTest)
        {
            f.Controls.AddRange(btns.ToArray());
        }
        else
        {
            // Add controls to random grid cells
            Button b1 = new Button();
            b1.Size = new Size(size, size);
            b1.Text = "B1";
            b1.Location = grid[3, 3];
            Button b2 = new Button();
            b2.Size = new Size(size, size);
            b2.Text = "B2";
            b2.Location = grid[5, 5];
            Button b3 = new Button();
            b3.Size = new Size(size, size);
            b3.Text = "B3";
            b3.Location = grid[8, 8];
            Button b4 = new Button();
            b4.Size = new Size(size, size);
            b4.Text = "B4";
            b4.Location = grid[8, 9];
            Button b5 = new Button();
            b5.Size = new Size(size, size);
            b5.Text = "B5";
            b5.Location = grid[9, 8];
            Button b6 = new Button();
            b6.Size = new Size(size, size);
            b6.Text = "B6";
            b6.Location = grid[9, 9];
            f.Controls.AddRange(new Button[] { b1, b2, b3, b4, b5, b6 });
        }

        f.ShowDialog();

    }
