How do I add an editable combobox to a System.Windows.Forms.PropertyGrid?
I have a System.Windows.Forms.PropertyGrid with different types of values. For a specific item, I want to show a list of useful values to choose from. The user may also type a new value. Something similar to a traditional dropdown combobox:
So far, I have my own System.ComponentModel.TypeConverter, but I can't figure out how to get both the dropdown with suggested values and the possibility to edit the value directly. Please help!
Solution
You can accomplish this by implementing your own UITypeEditor.
I recommend reading Getting the Most Out of the .NET Framework PropertyGrid Control. In particular, the section titled Providing a Custom UI for Your Properties walks through how to make a custom control for a specific property.
