How can I make a ComboBox non-editable in .NET?
提问by Cory Engebretson
I want to have a "select-only" ComboBoxthat provides a list of items for the user to select from. Typing should be disabled in the text portion of the ComboBoxcontrol.
我想要一个“仅选择” ComboBox，它提供一个供用户选择的项目列表。应在ComboBox控件的文本部分禁用键入。
My initial googling of this turned up an overly complex, misguided suggestion to capture the KeyPressevent.
我最初对此进行了谷歌搜索，结果发现一个过于复杂、误导性的建议来捕捉KeyPress事件。

To make the text portion of a ComboBox non-editable, set the DropDownStyle property to "DropDownList". The ComboBox is now essentially select-only for the user. You can do this in the Visual Studio designer, or in C# like this:
要使 ComboBox 的文本部分不可编辑，请将 DropDownStyle 属性设置为“DropDownList”。ComboBox 现在本质上是仅供用户选择的。您可以在 Visual Studio 设计器或 C# 中执行此操作，如下所示：
stateComboBox.DropDownStyle = ComboBoxStyle.DropDownList;

Stay on your ComboBox and search the DropDropStyle property from the properties window and then choose DropDownList.
留在您的 ComboBox 上并从属性窗口搜索 DropDropStyle 属性，然后选择DropDownList。

To add a Visual Studio GUI reference, you can find the DropDownStyleoptions under the Properties of the selected ComboBox:
要添加 Visual Studio GUI 参考，您可以DropDownStyle在所选组合框的属性下找到选项：
Which will automatically add the line mentioned in the first answer to the Form.Designer.cs InitializeComponent(), like so:
这将自动将第一个答案中提到的行添加到 Form.Designer.cs InitializeComponent()，如下所示：
this.comboBoxBatch.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList;

COMBOBOXID.DropDownStyle = ComboBoxStyle.DropDownList;
COMBOBOXID.DropDownStyle = ComboBoxStyle.DropDownList;

To continue displaying data in the input after selecting, do so:
要在选择后继续在输入中显示数据，请执行以下操作：
VB.NET
Private Sub ComboBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles ComboBox1.KeyPress
e.Handled = True
End Sub
C#
Private void ComboBox1_KeyPress(object sender, KeyPressEventArgs e)
{
e.Handled = true;
}
