Source control is null when accessing from a sub context menu item in C# -

-

i trying change color of button when click on sub menu item (colors > red) context menu strip.

this code attached user defined amount of buttons. figure out button trying change, trying go sub item source control such: sender > owner tool strip > owner menu > source control.

my code:

private void redtoolstripmenuitem_click(object sender, eventargs e) {     toolstripitem subitem = sender toolstripitem;     if (subitem == null) return;      toolstripitem mainitem = subitem.owneritem toolstripitem;     if (mainitem == null) return;      contextmenustrip menustrip = mainitem.owner contextmenustrip;     if (menustrip == null) return;      datagridview datagridview = menustrip.sourcecontrol datagridview;     if (datagridview == null) return; //null here      messagebox.show(datagridview.name); }

from i've found on google, appears bug. there workarounds this?
