如何将TableLayoutPanel中的所有列自动调整为完全相同的宽度？

Fro*_*840 4 .net tablelayoutpanel winforms

我正在尝试创建一个相当广泛的UserControl,将方形控件合并到设计中,并允许调整大小.因为设计需要正方形,所以我需要TableLayoutPanels中的所有列都具有相同的宽度,因此包含的停靠控件也是方形的.

不幸的是,TableLayoutPanel的行为并没有给我这个结果.
使用TableLayoutPanel,将所有列设置为使用相同百分比的Control,(在一组7列中)给出6个宽度相等的列,以及第7个宽度可变的列.
我知道出现这种情况是因为每7个大小中有6个,在7列周围没有相同数量的列像素,第7列是这个不等式的溢出.

我想我想要的是类似于第8列的其他7列的溢出,允许所有7个"真实"列具有实际相等的宽度,但是对于第8列允许为0宽度.
到目前为止,我找不到允许此行为的设置.

任何人都可以告诉我如何让TableLayoutPanel做我想要的,或者我将不得不开始编写大量的解决方法代码？

编辑:

为了回应Yacoder的回答,我添加了一些代码来演示这个问题,另一个代码显示了使用TableLayoutPanel和Dock属性的标准功能来解决它​​的不成功,天真的尝试

对于重新绘制此代码的糟糕表现,我深表歉意.

也许我不太明白这个问题,但是......那就是我所做的:

  1. 创建新表单
  2. 删除表单上的TableLayoutPanel,并设置Dock = Fill
  3. 在窗体设计窗口中(如果您使用的是VS),单击TableLayoutPanel上的小箭头打开包含任务的菜单,然后转到"编辑行和列..."
  4. 在该窗口中,根据需要添加尽可能多的列,并将所有列设置为整个大小的"百分比",并将相同的数字放在任何位置.您可以输入任何数字,只要确保它是相同的,VS将自动使总和等于100%.

并且...它应该工作,至少当我调整这样的形式我看到所有列重新调整大小...

如果您不在VS中,或者遇到该方法的麻烦,这是我在Designer类中自动生成的代码:

    this.tableLayoutPanel1.ColumnCount = 7;
    this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 14.28571F));
    this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 14.28571F));
    this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 14.28571F));
    this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 14.28571F));
    this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 14.28571F));
    this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 14.28571F));
    this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 14.28571F));
