TableLayoutPanel中列宽在运行时：奇怪的行为或错误 [英] TableLayoutPanel column widths at runtime: strange behavior or bug

问题描述

我有5个或7列一个TableLayoutPanel。用户可以点击显示/隐藏周末按钮，从5〜7天进行切换。

问题：当你开始用5天，然后preSS的5/7按钮，7列不是均匀分布... 6列要小得多那么剩下的。 奇怪的是，如果你开始使用7天​​，一切看起来OK。当您切换到5，然后回到7，还是一切都很好??

 无效lblSatSunday_Click（对象发件人，EventArgs的）
    {
        ！ShowZaterdagZondag = ShowZaterdagZondag;
        AddDisplayControls（）;
    }

    私人无效AddDisplayControls（）
    {
        tblPanel.SuspendLayout（）;
        tblPanel.Controls.Clear（）;
        tblPanel.ColumnCount = ShowZaterdagZondag？ 7：5; //＆LT;＆LT;＆LT; -------
        tblPanel.RowCount = 1;
        tblPanel.GrowStyle = TableLayoutPanelGrowStyle.FixedSize; // AddColumns;
        的for（int i = 0; I＆LT; tblPanel.ColumnCount;我++）
        {
            ColumnStyle CS =新ColumnStyle（SizeType.Percent，100 / tblPanel.ColumnCount）;
            tblPanel.ColumnStyles.Add（CS）;

            //添加手风琴
            手风琴A =新的手风琴（）;
            //删除code阅读
            tblPanel.Controls.Add（一）;
        }
        tblPanel.ResumeLayout（）;
    }
 

解决方案

在for循环添加这行code：

  tblPanel.ColumnStyles.Clear（）;
 

I have a tableLayoutPanel with either 5 or 7 columns. Users can click "show/hide weekend" button to switch from 5 to 7 days.

The problem : When you start with 5 days, then press the 5/7 button, the 7 columns are NOT spaced evenly ... column 6 is much smaller then the rest. The strange thing is that if you start with 7 days, all looks ok. When you switch to 5 and then back to 7, still all is fine ??

    void lblSatSunday_Click(object sender, EventArgs e)
    {
        ShowZaterdagZondag = !ShowZaterdagZondag;
        AddDisplayControls();
    }

    private void AddDisplayControls()
    {
        tblPanel.SuspendLayout();
        tblPanel.Controls.Clear();
        tblPanel.ColumnCount = ShowZaterdagZondag ? 7 : 5; // <<<-------
        tblPanel.RowCount = 1;
        tblPanel.GrowStyle = TableLayoutPanelGrowStyle.FixedSize;//.AddColumns;
        for (int i = 0; i < tblPanel.ColumnCount; i++)
        {
            ColumnStyle cs = new ColumnStyle(SizeType.Percent, 100 / tblPanel.ColumnCount);
            tblPanel.ColumnStyles.Add(cs);

            //Add accordeon
            Accordeon a = new Accordeon();
            //Removed code for reading
            tblPanel.Controls.Add(a);
        }
        tblPanel.ResumeLayout();
    }

解决方案

Add this line of code before the for loop:

 tblPanel.ColumnStyles.Clear();
