Adding ToolBoxData attribute in the inline code model user control using .net 3.5

Question

Hi,
     I have developed a Web User Control in inline code model. But not able to add in visual studio ToolBox as ToolBoxData attribute is not added. ToolBoxData attribute needs to be added just before the class declaration. But as inline code modle does not contain class declaration, so i don't have any idea about where to add ToolBoxData attribute into the inline code model page.
Please help me to suggest that where i can add ToolBoxData attribute in inline code model User Control.
