Hi,
I have a CListCtrl with 5 columns. I want that the horizontal scroll-bar will work only for the first column (I need that all the other 4 columns will be fixed to the right of the CListCtrl).
How do I do it ???

thanks,
Yoav.

Hi!
you can`t achieve this in the single control without big troubles.
simple solution is to combine two listcontrols side by side and allow scroll only in the first control.

I take it allowing the user to resize the columns isn't acceptable?

I did something simular ( actually I needed to keep first column in place and the rest of them scrolling)

It was done the following way:

1. OnHScroll was overriden and default handler wasn't called.
2. All codes were processed in my handler to find out new desired scrool position. ( There is a good sample on MSDN for that)
3. Column width were obtained.
4. Now tricky part - Columns positions were rearanged via Set/GetColumnOrder and Invalidate()
5. Scroll position were adjusted to make sure that left column were align with control edge.
6. SetScroll() was called.

That gave perfect illusion of scrolling everything but column 0.

Hope it helps.

By the way it took less than 100 lines of code total - so I wouldn't call it big trouble... :-)
