创建嵌套 TableLayoutPanel 时出现问题

Question

我正在尝试实现嵌套 TableLayoutPanel。我尝试在父 TableLayoutPanel 中动态创建/加载子 TableLayoutPanel。 为此，我采用父 TableLayoutPanel 并从 Visual Studio 工具箱中绘制它。 one DropDownList for dynamically to create child TableLayoutPanel I assign some values to dropdownlist such as 2*2,2*3,3*3,4*4 when the selected index change is fire is draws the child TableLayoutPanel. 我的代码在下面

private void cmbRowsColumns_SelectedIndexChanged(object sender, EventArgs e)
{   
  var selectedPair = new KeyValuePair<string, string>();
  selectedPair = (KeyValuePair<string, string>)cmbRowsColumns.SelectedItem;
  string[] rowcolumn = selectedPair.Value.Split('*');
  string strRowCount = rowcolumn[0];
  int rowCount = Convert.ToInt32(strRowCount);
  string strColumnCount = rowcolumn[1];
  int columnCount = Convert.ToInt32(strColumnCount);
  DynamicallyGenerateColumn(rowCount, columnCount);
}


private void DynamicallyGenerateColumn(int rowCount, int columnCount)
{
  parentTableLayoutPanel.Controls.Clear();
  parentTableLayoutPanel.ColumnStyles.Clear();
  parentTableLayoutPanel.RowStyles.Clear();
  parentTableLayoutPanel.ColumnCount = columnCount;
  parentTableLayoutPanel.RowCount = rowCount;
  for (int i = 0; i < columnCount; i++)
    {
      parentTableLayoutPanel.ColumnStyles.Add(new ColumnStyle(SizeType.AutoSize));
      for (int j = 0; j < rowCount; j++)
        {
        if (i == 0)
         {
          parentTableLayoutPanel.RowStyles.Add(new RowStyle(SizeType.AutoSize));
         }
          TableLayoutPanel objTableLayoutPanel = new  TableLayoutPanel();                  
          parentTableLayoutPanel.Controls.Add(objTableLayoutPanel, i, j);
       }
     }
 }

但实际上问题是当我创建子 TableLayoutPanel 格式不正确

Answer 1

我猜你想填充每个子面板所以你需要添加objTableLayoutPanel.Dock=DockStyle.Fill;

TableLayoutPanel objTableLayoutPanel = new  TableLayoutPanel(); 
objTableLayoutPanel.Dock = DockStyle.Fill;
parentTableLayoutPanel.Controls.Add(objTableLayoutPanel, i, j);
