c# - 如何将两个ToolStripComboBox 和Separator Horizo​​ntally 添加到一个ToolStripDropMenuItem？

Question

我认为这应该很容易做到。但我没见过。我想做类似的事情:

DropDown -> DropDownItem1 [ComboBox1 [|] ComboBox2], DropDownItem2 [...], DropDownItem3 [...];

我在 ToolStrip 中使用 ToolStripDropDownButton。我正在用 C# 编程。感谢您的建议。

看来你正在寻找这样的布局:

为此，您无需创建任何自定义控件。只需使用 ToolStrip 的常用功能即可。您需要设置 LayoutStyle属性设置为合适的值。

示例

private void Form1_Load(object sender, EventArgs e)
{
    var dropdown = new ToolStripDropDown();

    //Define style
    dropdown.LayoutStyle = ToolStripLayoutStyle.Table;
    var settings = (dropdown.LayoutSettings as TableLayoutSettings);
    settings.ColumnCount = 3;

    //First Item    
    var item1 = new ToolStripMenuItem("Some Sub Menu");
    dropdown.Items.Add(item1);
    settings.SetColumnSpan(item1, 3); //Set column span to fill the row

    //First Combo
    var combo1 = new ToolStripComboBox("combo1");
    combo1.Items.AddRange(new string[] { "Item1", "Item2", "Item3" });
    dropdown.Items.Add(combo1);

    //Separator
    dropdown.Items.Add("-");

    //Second Combo
    var combo2 = new ToolStripComboBox("combo2");
    combo2.Items.AddRange(new string[] { "Item1", "Item2", "Item3" });
    dropdown.Items.Add(combo2);

    //Last item
    var item2 = new ToolStripMenuItem("Some Othe Sub Menu");
    dropdown.Items.Add(item2);
    settings.SetColumnSpan(item2, 3); //Set column span to fill the row

    toolStripDropDownButton1.DropDown = dropdown;
}
