Question

我有一个tablelayout面板，我在其中以编程方式添加行。在第一次打开表单时向该容器添加行（使用带有新ValidationForm（）的语句）表格显示正常。第二次，由于某种原因，我在顶部添加了行？见这里的图片：

Extra Row lines at the top

这不会影响我使用的行数，只显示额外的行。每次关闭并打开表单时，行数都会增加。这是我用来添加行的代码：

private void insertRow(Label label, dynamic control)
    {
        // Create Panel
        var panel = new Panel();
        // Set Object Properties
        label.TextAlign = ContentAlignment.MiddleCenter;
        label.Dock = DockStyle.Fill;
        control.Dock = DockStyle.Fill;
        panel.Dock = DockStyle.Fill;

        //generate delete button
        var delete = new Button();
        delete.Text = "X";
        delete.ForeColor = System.Drawing.Color.Red;
        delete.MaximumSize.Height.Equals(40);
        delete.Name = rowCount.ToString();
        delete.Dock = DockStyle.Right;
        delete.Click += new EventHandler(deleteRow);

        // Add Controls to the panel
        panel.Controls.Add(control);
        panel.Controls.Add(delete);
        // add controls
        //tableLayoutPanel_Validations.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 48F));
        tableLayoutPanel_Validations.RowCount = rowCount + 1;
        tableLayoutPanel_Validations.Controls.Add(label, 0, rowCount);
        tableLayoutPanel_Validations.Controls.Add(panel, 1, rowCount);
        tableLayoutPanel_Validations.RowStyles.Add(new RowStyle(SizeType.AutoSize));
        rowCount++;
    }

rowCount是一个私有int，在运行时设置为0.

我的第一直觉是整个表格将重置＆＃34;在使用声明之后。表单声明是公共部分类ValidationForm：Form {}

使用声明打开表单：

using (AVBuilder.ValidationForm validationBuilder = new AVBuilder.ValidationForm())
        {
            if (validationBuilder.ShowDialog() == DialogResult.OK)
            {
                // ADD ITEM TO Validations LIST
                ListViewItem result = new ListViewItem(validationBuilder.resultObject + " : " + validationBuilder.resultName);
                result.SubItems.Add(validationBuilder.resultJson);
                result.ToolTipText = result.Text;
                listView_Validations.Items.Add(result);
                //MessageBox.Show(validationBuilder.resultJson);
            }
        }

确保rowCount变量未声明为static，因为它不会在新表单实例上重置为0.

TableLayoutPanel顶部的额外线？
