Question

我们可以在TableLayoutPanel中显示多个DataGridView吗？如果是，我们如何实现这一目标？我在msdn上搜索并搜索了它，但无法找到符合我要求的任何内容。

我可以动态多次显示标签，但我正在动态地查找DataGridView。

任何帮助将不胜感激。谢谢！

尝试以下

    public partial class Form1 : Form
    {
        const int WIDTH = 1200;
        const int HEIGHT = 1200;

        const int MARGIN = 200;

        const int NUMBER_OF_ROWS = 2;
        const int NUMBER_OF_COLS = 2;

        static List<DataGridView> dgvs = new List<DataGridView>();
        public Form1()
        {
            InitializeComponent();

            this.Width = WIDTH;
            this.Height = HEIGHT;

            TableLayoutPanel panel = new TableLayoutPanel();
            this.Controls.Add(panel);

            panel.Height = HEIGHT - MARGIN;
            panel.Width = WIDTH - MARGIN;
            panel.ColumnCount = NUMBER_OF_COLS;
            panel.RowCount = NUMBER_OF_ROWS;

            for (int row = 0; row < NUMBER_OF_ROWS; row++)
            {
                for (int col = 0; col < NUMBER_OF_COLS; col++)
                {
                    DataGridView newDGV = new DataGridView();
                    dgvs.Add(newDGV);
                    newDGV.Height = (HEIGHT - MARGIN) / NUMBER_OF_ROWS;
                    newDGV.Width = (WIDTH - MARGIN) / NUMBER_OF_COLS;
                    newDGV.Left = 50;
                    newDGV.Top = 50;
                    panel.Controls.Add(newDGV, col, row);
                }
            }

        }

目前尚不清楚如何显示子控件。您提到可以使用Label执行此操作，但是您没有显示任何代码，这有助于澄清。对于DataGridView，它完全相同。

正如您已经注意到，您只能将一个控件放在TableLayoutPanel＆＃34;单元格＆＃34;中。如果您想要单元格中的多个控件，可以先向Panel添加TableLayoutPanel，然后将多个子控件添加到Panel。

但是，我认为您真正想要的是TableLayoutPanel中可变数量的列或行，然后每个单元格添加一个DataGridView。

首先，创建TableLayoutPanel或获取现有实例。

// If you are using an existing table layout panel, either clear the controls, rows and columns beforehand,
// or keep track of them manually and adjust accordingly.
tableLayoutPanel.Controls.Clear();
tableLayoutPanel.RowStyles.Clear();
tableLayoutPanel.ColumnStyles.Clear();

IList<DataGridView> dataGridViews = ... /* wherever you get your data grid views from */

for (int i = 0; i < dataGridViews.Count; ++i)
{
    // The arguments to ColumnStyle control the size of the column.
    // If you want to arrange them vertically instead of horizontally, use RowStyles instead.
    // If you want a combination, you have to figure out the logic yourself.
    // In case of SizeType.Percent, "width" defines a relative weight, not necessarily percent.
    // If all widths are equal (no matter the value), all columns will be equally wide.
    tableLayoutPanel.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, width: 1));

    dataGridViews[i].Dock = DockStyle.Fill;
    // This adds the data grid view into that specific cell.
    tableLayoutPanel.Controls.Add(dataGridViews[i], column: i, row: 0);
}
