Hello,

i have a PropertyGrid with some Propertys from my Object, and One of these Properties has a List (Like ComboBox). This Property has a StringConverter and an UITypeEditor.

The Methods of these Objects were called, and return correctly Types, also the DropDownBox ist there and i can click this an he show me the Values and so on, but i will not press the Triangle to show the values, i will click anywhere in the property to display the drop-down list via Events or so.

How i make this ?

I searched for it, but nothing possible found Frown | :(

Solution 1

If the property type is an enumeration, it should work out of the box.

If it is something more sophisticated, you will have to create a custom TypeConverter[^] and override its GetStandardValuesSupported(), GetStandardValuesExclusive() and GetStandardValues() methods.

To make the displayed values usable, you will have to add overrides for CanConvertTo(), ConvertTo(), CanConvertFrom() and ConvertFrom(). They are used to convert your settings to/from the string that is displayed in the dropdown.

Do your custom TypeConverter methods get called when you try to drop the list down?

Does your custom TypeConverter return the correct StandardValuesCollection?

Can you post your custom TypeConverter code (using the "Improve question" link)?
