有没有一种简单的方法在WinForms中实现Checked Combobox

有谁知道在WinForms中检查combobox的简单实现？ 谷歌搜索时我找不到任何东西。

我想要的东西就像这个Windows预定任务触发器编辑：

这就是你想要的，我只是自己编码
这个概念非常简单，使用面板并在其上添加复选框。 然后强制combobox禁用它的下拉菜单，但仍然可以单击其向下箭头。 使用combobox的DropDown和DropDownClosed事件。 当您将combobox的列表设置为面板的Visible属性为True ，在关闭combobox的下拉列表时将其隐藏。

 //designer class // // comboBox1 // this.comboBox1.DrawMode = System.Windows.Forms.DrawMode.OwnerDrawFixed; this.comboBox1.DropDownHeight = 1; this.comboBox1.DropDownWidth = 1; this.comboBox1.FormattingEnabled = true; this.comboBox1.IntegralHeight = false; this.comboBox1.Location = new System.Drawing.Point(256, 371); this.comboBox1.Name = "comboBox1"; this.comboBox1.Size = new System.Drawing.Size(238, 21); this.comboBox1.TabIndex = 5; this.comboBox1.DropDown += new System.EventHandler(this.comboBox1_DropDown); this.comboBox1.DropDownClosed += new System.EventHandler(this.comboBox1_DropDownClosed); // // panel1 // this.panel1.BackColor = System.Drawing.Color.White; this.panel1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle; this.panel1.Controls.Add(this.checkBox9); this.panel1.Controls.Add(this.checkBox8); this.panel1.Controls.Add(this.checkBox7); this.panel1.Controls.Add(this.checkBox6); this.panel1.Controls.Add(this.checkBox5); this.panel1.Controls.Add(this.checkBox4); this.panel1.Controls.Add(this.checkBox3); this.panel1.Controls.Add(this.checkBox2); this.panel1.Controls.Add(this.checkBox1); this.panel1.Location = new System.Drawing.Point(252, 394); this.panel1.Name = "panel1"; this.panel1.Size = new System.Drawing.Size(245, 68); this.panel1.TabIndex = 6; // // checkBox9 // this.checkBox9.AutoSize = true; this.checkBox9.Location = new System.Drawing.Point(162, 48); this.checkBox9.Name = "checkBox9"; this.checkBox9.Size = new System.Drawing.Size(80, 17); this.checkBox9.TabIndex = 9; this.checkBox9.Text = "checkBox9"; this.checkBox9.UseVisualStyleBackColor = true; // // checkBox8 // this.checkBox8.AutoSize = true; this.checkBox8.Location = new System.Drawing.Point(162, 27); this.checkBox8.Name = "checkBox8"; this.checkBox8.Size = new System.Drawing.Size(80, 17); this.checkBox8.TabIndex = 8; this.checkBox8.Text = "checkBox8"; this.checkBox8.UseVisualStyleBackColor = true; // // checkBox7 // this.checkBox7.AutoSize = true; this.checkBox7.Location = new System.Drawing.Point(162, 4); this.checkBox7.Name = "checkBox7"; this.checkBox7.Size = new System.Drawing.Size(80, 17); this.checkBox7.TabIndex = 7; this.checkBox7.Text = "checkBox7"; this.checkBox7.UseVisualStyleBackColor = true; // // checkBox6 // this.checkBox6.AutoSize = true; this.checkBox6.Location = new System.Drawing.Point(82, 47); this.checkBox6.Name = "checkBox6"; this.checkBox6.Size = new System.Drawing.Size(80, 17); this.checkBox6.TabIndex = 5; this.checkBox6.Text = "checkBox6"; this.checkBox6.UseVisualStyleBackColor = true; // // checkBox5 // this.checkBox5.AutoSize = true; this.checkBox5.Location = new System.Drawing.Point(82, 26); this.checkBox5.Name = "checkBox5"; this.checkBox5.Size = new System.Drawing.Size(80, 17); this.checkBox5.TabIndex = 4; this.checkBox5.Text = "checkBox5"; this.checkBox5.UseVisualStyleBackColor = true; // // checkBox4 // this.checkBox4.AutoSize = true; this.checkBox4.Location = new System.Drawing.Point(82, 4); this.checkBox4.Name = "checkBox4"; this.checkBox4.Size = new System.Drawing.Size(80, 17); this.checkBox4.TabIndex = 3; this.checkBox4.Text = "checkBox4"; this.checkBox4.UseVisualStyleBackColor = true; // // checkBox3 // this.checkBox3.AutoSize = true; this.checkBox3.Location = new System.Drawing.Point(3, 47); this.checkBox3.Name = "checkBox3"; this.checkBox3.Size = new System.Drawing.Size(80, 17); this.checkBox3.TabIndex = 2; this.checkBox3.Text = "checkBox3"; this.checkBox3.UseVisualStyleBackColor = true; // // checkBox2 // this.checkBox2.AutoSize = true; this.checkBox2.Location = new System.Drawing.Point(4, 24); this.checkBox2.Name = "checkBox2"; this.checkBox2.Size = new System.Drawing.Size(80, 17); this.checkBox2.TabIndex = 1; this.checkBox2.Text = "checkBox2"; this.checkBox2.UseVisualStyleBackColor = true; // // checkBox1 // this.checkBox1.AutoSize = true; this.checkBox1.Location = new System.Drawing.Point(4, 4); this.checkBox1.Name = "checkBox1"; this.checkBox1.Size = new System.Drawing.Size(80, 17); this.checkBox1.TabIndex = 0; this.checkBox1.Text = "checkBox1"; this.checkBox1.UseVisualStyleBackColor = true;

 public Form1() { InitializeComponent(); panel1.Visible =false; } private void comboBox1_DropDown(object sender, EventArgs e) { panel1.Visible = true; } private void comboBox1_DropDownClosed(object sender, EventArgs e) { panel1.Visible = false; } 

Answer 2

只需快速浏览一下截图，看起来实际上有两个控件，一个combobox和一个checklistbox。 您应该可以使用combobox的DropDown方法使checklistbox可见，然后一旦用户离开checklistbox，将选中的值作为文本附加到combobox（并使checklistbox再次不可见）。 只是一个想法; 无法访问编辑器以查看是否可行，但似乎很可能。
