DropDownListEditor for Enum: Change display text

[Jay]

I have a complex object and one of the variables is an enum. When I assign the object to the PropertyGrid's selected item, it generates a DropDownListEditor for the enum row correctly. However, the display text is automatically the ToString of the enum, which is not ideal for users to see and read. I want to change the display text to be the Description tagged to the enum values but I can't figure out a way to change what the DropDownListEditor displays or to update the values databound to the dropdown to achieve what I want.

 

public enum ExposureMode
    {
        [Description("Full Auto")] FullAuto,
        [Description("Auto Filter, Fixed Exposure")] AutoFilFixedExp,
        [Description("Fixed Filter, Auto Exposure")] FixedFilAutoExp,
        [Description("Fixed Filter, Fixed Exposure")] FullFixed
    }

 

So I want the Descriptions to be displayed instead of the ToString (i.e. "Auto Filter, Fixed Exposure" instead of AutoFilFixedExp).

I've just done this for several enum types. You need a TypeConverter for each enum type, which is documented in the Telerik docs.

However, despite appearances being good, when I change the dropdown selection it does not propagate back to my object's property for some reason, even after pressing Enter.

Does anyone know why this might be?

Hello Tino, 

Thank you for writing.  

Each property item is associated with a specific property from the SelectedObject in RadPropertyGrid. If the TypeConverter is implemented correctly, it is not supposed to experience any undesired behavior. Could you please specify the exact steps how to reproduce the problem? A better option would be to submit a support ticket where you can provide a sample project demonstrating the issue. Thus, Telerik support will gladly assist you in resolving this case.

I hope this information helps.
