Another EnumConverter problem

[e laj]

I have the following enum:

\[TypeConverter(typeof(E1C))\]
public enum E1
{
	a = 1,
	b = 2,
	c = 3
}

And the following converter:

public class E1C : EnumConverter
{
	public E1C(): base(typeof(E1))
	{
	}
	public override object ConvertTo(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value, Type destinationType)
	{
		if(value != null)
		{
			if(destinationType == typeof(string))
			{
				if((E1)value == E1.a)
				{
					return "a a a";
				}
				else if((E1)value == E1.b)
				{
					return "b b b";
				}
				else if((E1)value == E1.c)
				{
					return "c c c";
				}
			}
			if(destinationType == typeof(InstanceDescriptor))
			{
				FieldInfo fi = EnumType.GetField(value.ToString());
				if(fi != null)
				{
					return new InstanceDescriptor(fi, null);
				}
			}
		}
		return base.ConvertTo (context, culture, value, destinationType);
	}

	public override object ConvertFrom(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value)
	{
		if(value != null && value is string)
		{
			if((string) value == "a a a")
			{
				return E1.a;
			}
			else if((string) value == "b b b")
			{
				return E1.b;
			}
			else if((string) value == "c c c")
			{
				return E1.c;
			}
		}
		return base.ConvertFrom (context, culture, value);
	}
}

Now, on the property page every thing works fine, as well as in ASP .net page, but within Windows Form, the designer generates the folowing code:

	#region Windows Form Designer generated code
	...
	...		
	this.userControl11.E1 = WindowsApplication2.E1.b b b;
	...
	...
	#endregion

As you can see, instead of generating: **this.userControl11.E1 = WindowsApplication2.E1.b;** It generated: **this.userControl11.E1 = WindowsApplication2.E1.b b b;** If anyone know this problem and its solution, it would be nice! Thanks in advance! Ilan

Hi there, You should apply the TypeConverter attribute to the E1 property of the UserControl1 class instead of the enum E1 definition:

public class UserControl1 : System.Windows.Forms.UserControl
{
...

\[TypeConverter(typeof(E1C))\]	
public E1 E1
{
	...
}
              
...

}

However, IMO this question should belong to the C# forum.

Thanks! Yes i have noticed that this this question fits C#, but only after i pressed "Post" (and then i re-posted it in the C# forum). Seems that i start to like ASP.net:-) And again thank you very much!
