I am hoping someone has run into this.I have a property of type string that I created a custom ui type editor for. This part is working great the editor pops up and the text is reflected back on the property sheet for that property. However the changes to the property value are not serialized back to the class unless I manually type something on the property sheet. Even though the text I type in custom editor is being reflected back to the property sheet property value some event or something is not firing to know that the value of that property has changed. Any ideas? Paul

Whatever value you return from the EditValue() override within the type editor will be set back in the property sheet, but the value will not be set on the object. Generally, you will need to use this:context.PropertyDescriptor.SetValue(context.Instance, "MyValue") Which uses the property descriptor to set the actual value on the design-time instance, which is then detected and serialized into the .designer.* file.

Lol I can handle that I'll make it a double!How bout another question? I have a property called report and its type is "xtrareportbase" which is my sublass of an xtrareport. Of course in the property sheet this is a dropdown but a devexpress xtrareport is not a component so I canot drag one onto the design surface to allow it to be selected from the combo. I am thinking that I will have to follow the same idea of using a ui type editor and type converter and then use reflection to loop through the assemply to find all the report types in the project to be able to select the one i want and then update the property grid. Does this sound like I'm going down the right path or am I in the weeds again?

No, you're on the right track... in fact, that's what we do with the ListPopulation type editors. Once you have an Assembly object, you can call GetTypes() which will return a Type array containing all of the public types (by default, but you can specify flags to grab the private types as well), and on each one you can check if Type.IsSubClassOf(GetType(xtrareport)) then add it to the list and once they select one of the types, then you can create a new instance of it and stuff it in the property value using that context.PropertyDescriptor.SetValue() method.

Something like thisDim LoAssy As Reflection.Assembly = Reflection.Assembly.GetExecutingAssembly()For Each loType As Type In LoAssy.GetTypes()If loType.IsSubclassOf(GetType(ReportEngine.XtraReportBase)) Thenpopulate combo or something End If Next

Something like that... however, you won't be able to get the executing assembly at design-time... you'll probably have to do this:For Each loAssembly As Assembly In AppDomain.CurrentDomain.GetAssemblies()
'-- Don't check the assembly if the name starts with System, DevExpress, Microsoft, etc.
If loAssembly.Name.FullName.StartsWith("System") OrElse _ ' etc... Then
'-- Cycle through all of the types...
End If
Next

Actually, now that I think about it, you can get the executing assembly, you just cannot get the entry assembly. However, you might want to still use the AppDomain trick just in case your report is not located within the same assembly as your type editor.

This is Awesome!! Thanks alot for the help.. Feel like I just opened my eyes after walking around with em closed!!When I started with reflection, I felt like I was playing Doom3... you're walking around an absolutely huge, pitch-black room with nothing but a dinky flashlight, so you can only look at one thing at a time. However, once you've gone through the game a few times, you can navigate the room by by touch because you know where everything is
