linking controls across partial class files

[alevine]

I have a C# studio 2005 GUI app that has multiple tabs with multiple controls on each tab. To make the source files more manageable I split the functions associated with each tab across source files using the partial class keywords.
The linkage between the IDE/Control/Methods do not work anymore.
i.e. Before splitting into partial classes if I clicked on a button in the form the IDE would put the focus at the code for that button.

Does anyone know if this liknkage can be restored using the partial class across multiple files? If so, how is this done?
