 | EditValue | Overloaded.
EditValue must be overridden from UITypeEditor to install a control that appears in the drop down.
For UITypeEditorEditStyle.DropDown, here is the general procedure:
1. Get the Edit Service from pProvider.GetService(typeof(IWindowsFormsEditorService)).
It contains methods to run the DropDown and Forms interfaces.
2. Get a Window control instance that reflects the UI you want. In this case, its a ListBox.
If you wanted multiple controls, consider something like the Panel class and add controls to its Controls list.
3. We want the ListBox to close on a Click event much like boolean and enum dropdowns do.
So we set up a Click event handler that calls CloseDropDown on the Edit Service.
4. Add data to the ListBox.
5. Set the initial value of the list. pValue contains that value.
6. Let the Edit Service open and manage the DropDown interface.
7. Return the value from the list.

| | Name | Description |

 | AddSupportedType |
AddSupportedType adds a type into the xTypesSupported list. Call it from
DefineSupportedTypes. All subclasses of any type added are automatically supported.
|
| ClearSupportedTypes |
Clear supported types.
|
| DefineSupportedTypes |
DefineSupportedTypes must be overridden. Use it to call AddSupportedType with Control type that you support.
Remember that all subclasses of any type added are automatically supported.
For example, if you want to include all HtmlControls, call AddSupportedTypes(typeof(HtmlControl)).
You can use pContext.Instance to get a hold of the control whose property is being edited.
|
| FillInList | Overridden.
FillInList box gathers the controls found on the page and after filtering out those
not in xTypesSupported, adds their ClientID to the list box.
The ITypeDescriptorContext, pContext, contains the components list of the page.
|
| FillInListWithControls |
FillInListWithControls does most of the work of FillInList.
|
| List_Click |
List_Click is a click event handler for the ListBox. We want the have the list
close when the user clicks, just like the Enum and Bool types do in their UITypeEditors.
