Last Visible Column

[Administrator]

I''m trying to get the last visible column. You previously told me:

this.ViewLayout.LastVisibleCol

which works great, EXCEPT, I need to get it from the OnLayout() in my derived grid control, which is causing it to be out of date. For example, if I have 4 columns visible and resize to 3 columns visible, it will give me 4 instead of 3. Then if I resize to 4, it gives me 3. Basically, it''s a step behind.

This happens even if I call base.OnLayout() first.

Is there a way to get this number updated because I need it in the OnLayout to figure out whether or not to show my scroll bars.

Thanks.

Try calling this.ViewLayout.Reset before you try to access the this.ViewLayout.LastVisibleCol to see if that handles this problem.

Nope. Same response...

I do not think I see a problem in this sample. It seems to have the proper value of LastVisibleCol as I size the form. Do you see the problem in this sample? LayoutOverride_8594.zip

It''s working fine in your example.

When I do the same before & after tracing in my code, however, I get the same value both before and after, the base.OnLayout() call.

Very strange. I''ll see if I can figure out some reason it''s not getting updated in the OnLayout call, but nothing is coming to mind at this point.

Found a solution. Kinda kludgy, but it works and doesn''t appear to have any noticeable side-effects. Thanks for your help. It got me looking in the right place.
