删除 TableLayoutPanel 中的 Row 会导致布局问题

Question

我有一个 WinForms 应用程序，它有一个TableLayoutPanel; 这是定义代码：

tableLayoutPanel1 = new TableLayoutPanel();

tableLayoutPanel1.Dock = DockStyle.Fill;

tableLayoutPanel1.AutoScroll = true;

tableLayoutPanel1.RowCount = users.Count + 1;

tableLayoutPanel1.ColumnCount = 1;

tableLayoutPanel1.GrowStyle = TableLayoutPanelGrowStyle.FixedSize;

tableLayoutPanel1.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 100F));

foreach (String user in users)

{

    tableLayoutPanel1.RowStyles.Add(new RowStyle(SizeType.Absolute, 600F));

}

tableLayoutPanel1.RowStyles.Add(new RowStyle(SizeType.Absolute, 600F));

int index = 0;

foreach (String user in users)

{

    AddDockedControl(index, user);

    index++;

}

AddDockedControl(index, null);

panel1.Controls.Add(tableLayoutPanel1);

private void AddDockedControl(int row, String userName)

{

    AccountRowUC newUser = new AccountRowUC(this, userName, row);

    newUser.BorderStyle = BorderStyle.FixedSingle;

    newUser.Dock = DockStyle.Top;

    tableLayoutPanel1.Controls.Add(newUser, 0, row);

}

现在，当我想删除其中一行时，我正在使用以下代码：

public void RemoveRowAtIndex(int index)

{

    if (index >= tableLayoutPanel1.RowCount)

        return;

    // delete all controls of row that we want to delete

    for (int i = 0; i < tableLayoutPanel1.ColumnCount; i++)

    {

        var control = tableLayoutPanel1.GetControlFromPosition(i, index);

        tableLayoutPanel1.Controls.Remove(control);

    }

    // move up row controls that comes after row we want to remove

    for (int i = index + 1; i < tableLayoutPanel1.RowCount; i++)

    {

        for (int j = 0; j < tableLayoutPanel1.ColumnCount; j++)

        {

            var control = tableLayoutPanel1.GetControlFromPosition(j, i);

            if (control != null)

                tableLayoutPanel1.SetRow(control, i - 1);

        }

    }

    // remove last row

    tableLayoutPanel1.RowStyles.RemoveAt(tableLayoutPanel1.RowCount - 1);

    //tableLayoutPanel1.RowStyles.RemoveAt(index);

    tableLayoutPanel1.RowCount--;

}

问题是当我删除一个 Row 时，表格底部会留下一个很大的空间：TableLayoutPanel 不会回收panel1.

Answer 1

基于评论中描述的布局的解决方案和之前发布的此答案：Center multiple rows of controls in a FlowLayoutPanel描述：（本文底部提供的测试表格的完整代码）创建一个新表单（这里，命名为frmTLPTest1）添加两个面板。一个用于承载一些按钮，另一个将是 TableLayoutPanel 的容器。将 Container 面板设置为AutoScroll = true,&nbsp;AutoSizeMode = AutoSizeMode.GrowAndShrink, 设置所有 Anchors (Left, Top, Right, Bottom)在 Container 面板中，放置一个新的 TableLayoutPanel：将其设置为AutoSize = true,&nbsp;AutoSizeMode = AutoSizeMode.GrowAndShrink,Dock = DockStyle.Top从 TableLayoutPanel 中删除所有行和列，除了每个行和列（不能全部删除）。将两者的尺寸设置为AutoSize。重要说明（也在链接答案中报告）：在 Form 构造函数中，删除了其中一个 RowStyles。这很重要：TLP 将保留 2 个 RowStyle。一个应用于现有的 Row；第二种样式将应用于您添加的第一行：仅应用于第一个，而不应用于其他。如果不删除此样式，则会影响布局。用于向 TableLayoutPanel 添加行/从 TableLayoutPanel 中删除行的核心方法，使用 FlowLayoutPanel 作为 TLP Row 内容，最终也可以用作其他控件的容器。TlpAddRow(TableLayoutPanel tlp, bool addRowCount)方法：将新的 FlowLayoutPanel 添加到指定的 TableLayoutPanel 的 Cell 中，并在请求时添加新的 Row。由于设计器不允许删除所有行，因此第一行(FlowLayoutPanel) 不得增加行数：addRowCount参数将设置为false.private Control TlpAddRow(TableLayoutPanel tlp, bool addRowCount){&nbsp; &nbsp; var flp = new FlowLayoutPanel() {&nbsp; &nbsp; &nbsp; &nbsp; Anchor = AnchorStyles.Top | AnchorStyles.Bottom,&nbsp; &nbsp; &nbsp; &nbsp; AutoSize = true,&nbsp; &nbsp; &nbsp; &nbsp; AutoSizeMode = AutoSizeMode.GrowAndShrink,&nbsp; &nbsp; };&nbsp; &nbsp; tlp.SuspendLayout();&nbsp; &nbsp; if (addRowCount) tlp.RowCount += 1;&nbsp; &nbsp; tlp.Controls.Add(flp, 0, tlp.RowCount - 1);&nbsp; &nbsp; tlp.ResumeLayout(true);&nbsp; &nbsp; return flp;}TLPRemoveRow(TableLayoutPanel tlp, Control control)方法（重载）：允许从指定的 TableLayoutPanel 中删除行。要删除的 Row 可以从用作 Row Container 的 Control 派生（此处为 FlowLayoutPanel，但它可以是 Panel、另一个 TableLayoutPanel 或其他一些类型的 Container 控件）。也可以通过直接指定 Row 索引来移除 Row。private void TLPRemoveRow(TableLayoutPanel tlp, Control control){&nbsp; &nbsp; int ctlRow = tlp.GetRow(control);&nbsp; &nbsp; TLPRemoveRow(tlp, ctlRow);}private void TLPRemoveRow(TableLayoutPanel tlp, int row){&nbsp; &nbsp; if (row < tlp.RowCount - 1) {&nbsp; &nbsp; &nbsp; &nbsp; for (int i = row; i < tlp.RowCount - 1; i++) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; tlp.SetRow(tlp.GetControlFromPosition(0, i + 1), i);&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; tlp.RowCount -= 1;}此布局的视觉结果：https://i.stack.imgur.com/hJs0i.gif 由于通过测试而不是解释更容易理解它的工作原理，因此这是表单的完整布局：测试表格( frmTLPTest1):using System.Drawing;using System.Linq;using System.Windows.Forms;public partial class frmTLPTest1 : Form{&nbsp;
