在TableLayoutPanel中动态添加行

Question

我想在c#中的Windows窗体中的TableLayoutPanel中逐行动态添加这些条目

我怎样才能做到这一点？

Answer 1

试试下面的代码,

// TableLayoutPanel Initialization
TableLayoutPanel panel = new TableLayoutPanel();
panel.ColumnCount = 3;
panel.RowCount = 1;
panel.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 40F));
panel.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 30F));
panel.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 30F));
panel.RowStyles.Add(new RowStyle(SizeType.Absolute, 50F));
panel.Controls.Add(new Label() { Text = "Address" }, 1, 0);
panel.Controls.Add(new Label() { Text = "Contact No" }, 2, 0);
panel.Controls.Add(new Label() { Text = "Email ID" }, 3, 0);

// For Add New Row (Loop this code for add multiple rows)
panel.RowCount = panel.RowCount + 1;
panel.RowStyles.Add(new RowStyle(SizeType.Absolute, 50F));
panel.Controls.Add(new Label() { Text = "Street, City, State" }, 1, panel.RowCount-1);
panel.Controls.Add(new Label() { Text = "888888888888" }, 2, panel.RowCount-1);
panel.Controls.Add(new Label() { Text = "xxxxxxx@gmail.com" }, 3, panel.RowCount-1);

我知道这个问题已经很老了,但是有人可以把它作为有用的东西.

首先要注意petchirajan的答案是好的,但是如果你有至少一个现有的行(例如标题)并且你想使用可视编辑器使用高度设置继续列表,而不修改代码,你可以使用:

private void AddItem(string address, string contactNum, string email )
    {
        //get a reference to the previous existent 
        RowStyle temp = panel.RowStyles[panel.RowCount - 1];
        //increase panel rows count by one
        panel.RowCount++;
        //add a new RowStyle as a copy of the previous one
        panel.RowStyles.Add(new RowStyle(temp.SizeType, temp.Height));
        //add your three controls
        panel.Controls.Add(new Label() {Text = address}, 0, panel.RowCount - 1);
        panel.Controls.Add(new Label() { Text = contactNum }, 1, panel.RowCount - 1);
        panel.Controls.Add(new Label() { Text = email }, 2, panel.RowCount - 1);
    }

如果您更喜欢泛型表的泛型方法:

private void AddRowToPanel(TableLayoutPanel panel, string[] rowElements)
    {
        if (panel.ColumnCount != rowElements.Length)
            throw new Exception("Elements number doesn't match!");
        //get a reference to the previous existent row
        RowStyle temp = panel.RowStyles[panel.RowCount - 1];
        //increase panel rows count by one
        panel.RowCount++;
        //add a new RowStyle as a copy of the previous one
        panel.RowStyles.Add(new RowStyle(temp.SizeType, temp.Height));
        //add the control
        for (int i = 0; i < rowElements.Length; i++)
        {
            panel.Controls.Add(new Label() { Text = rowElements[i] }, i, panel.RowCount - 1);
        }
    }

您也可以使用Collection而不是使用数组来执行此操作

 private void AddRowToPanel(TableLayoutPanel panel, IList<string> rowElements)
    ...

希望能帮助到你.
