CheckedListBox Losing Checks

[Brian Mitchell]

I have no idea what I am doing wrong, but I have a CheckedListBox (Bound to
an IList) on a TabControl and everytime I switch tabs I lose my checks. Is
there something I'm missing? If I look at the properties of my IList class I
can still see the properties have not changed (which means the items in the
box should still be chekced) it's just like for some reason the ListBox
doesn't keep the checks.

Thanks for the help!!

Found an MSDN article telling me it's a bug....bummer.

heh, this seems to be noticed in waves. seen this a few times in the last
couple days.
I ran into this a long time ago.
It appears that the TabControl is somehow preventing or causing the
CheckedListBox to not render correctly. The TabControl sometimes also seems
to affect other controls as well, but the CheckedListBox seems to be the
most affected.
I don't have a simple fix, and so far I have not come across a good
explanation or fix.
In my case, I really needed special behaviour, so I extended the
CheckedListBox control myself. So far I have not seen the same problem with
the version I'm using.

Maybe someone else has come across a solution by now?

Ah, forgot about that article.
However, contrary to their comment about it only affecting Data Bound
CheckedListBoxes, in every situation it has happened to me, there was no
data binding involved.

Thanks for the reply, what I ended up doing is just iterating through my
datasource and manually populating the list with the objects. This seems to
work....at least for now.

Brian,

I am not sure of this, however I thought that the Ilist binding was a one
way binding, only setting of the control and not the other way.
