Combobox使用TypeConverter而不是toString C＃

Question

I have a class with a custom TypeDescriptor to save and restore the data. In my application i use a ComboBox to select objects of this class. To bind the objects to the ComboBox i use the DataSource property of the ComboBox .

After I created the custom TypeDescriptor for my class, the ComboBox uses the TypeDescriptor to display the Text instead of the ToString method of my class.

How can I change the ComboBox to use the ToString method instead of the TypeDescriptor ?

Answer 1

By using a wrapper class and populate the ComboBox with that?

private class ComboItem
{
    private MyClass theWrappedInstance;

    internal ComboItem(MyClass c)
    {
        theWrappedInstance = c;
    }

    public override ToString()
    {
        return theWrappedInstance.ToString();
    }
}
