winforms - Visual Studio 2008 "Document Outline" stopped working for the main form in my project -


i'm big fan of rather obscure "document outline" window in vs 2008 (it's buried in view -> other windows menu).

it's way know view of containment heirarchy complicated winform has lot of nested controls.

some months ago, stopped working complicated form in winforms project. displays "there no items show selected document", no matter select in designer.

no clue broke - form contains mix of common ms controls , third party controls (mainly devexpress). several splitcontainers, document outline had no problem these.

anybody else seen this, , suggestions on how fix it?

after poking around, solved problem myself.

i started deleting controls form, see happen.

turns out 3rd party grid i'm using caused problem - when reconfigured it, problem went away. (looks bug in control, i've reported vendor).

interesting...misbehaving controls can break vs ide, not apps.
