What I think you want to do is set the Flags attribute on your enum list, and then add another item to it:

C#

[Flags]
public enum JSFunctions      
{
    None=0,
    OnChange=1,
    OnClick=2,
    OnKeyUp=4,
    OnKeyDown=8,
    Onhelp=16,
    Onblur=32,
    Onfocus=64,
    Ondblclick=128,
    onmousedown=256,
    onmousemove=512,
    onmouseup=1024,
    onmouseout=2048,          
    OnChange_OnKeyUp=4096,
    OnChange_OnKeyDown=8192,
    OnChange_Onblur=16384,
    All=32768
}

At that point, you can set multiple enum values to your EventList property like this:

C#

this.EventList &= (JSFunctions.OnKeyUp & JSFunctions.Onhelp);

At this point, all you have to do to set the control's EventList property is to write a method that builds a string from the flags.

C#

private string GetFlagIfSet(JSFunctions jsfuncs, JSFunction func)
{
    string flagName = "";
    if (jsfuncs != JSFunction.None)
    {
        if ((jsFuncs | func) == func)
        {
            flagName = string.Format("{0};", func.ToString());
        }
    }
    return flagName;
}

I'll leave the rest for you to fill in (and keep in mind I did this off the top of my head, so it may need some tweaking).

Go forth and code.
