How to Add Both Text and Value to ComboBox Items in C# Without Data Binding?

Add text and value to combo box item in C# WinForms app

Many answers about adding text and values ​​to combo box items in C# WinForms applications involve data binding. However, if there is no ready-made binding source, another approach is needed.

To achieve this, create a custom class and override the ToString() method to return the desired text. Here's a simple example:

public class ComboboxItem
{
    public string Text { get; set; }
    public object Value { get; set; }

    public override string ToString()
    {
        return Text;
    }
}

How to use it:

private void Test()
{
    ComboboxItem item = new ComboboxItem();
    item.Text = "项目文本1";
    item.Value = 12;

    comboBox1.Items.Add(item);

    comboBox1.SelectedIndex = 0;

    MessageBox.Show((comboBox1.SelectedItem as ComboboxItem).Value.ToString());
}

This makes it possible to add text and values ​​to combo box items without binding a source.
