I've got the code compiling and running (apparently), but no icon ever appears in the column header, and of course it doesn't change...it doesn't seem to do anything.

Does this work using the headers imagelist? Any idea as to what I'm doing wrong?

Sorry, I was trying to do it in VB with an existing project and as I said it just wasn't working. I created a new project, and there its working. Not sure what I was doing wrong with the existing project, but I'l get it.

Hi John,

My guess would be that a constant wasn't being referenced correctly.

Good luck,
Farhan

I finally figured out why it was working with a new project and not with the old one, I didn't have XP visual styles enabled (was going to add it to another existing project, which also didn't have XP styles enabled).

I am glad that you figured it out. It is a little weird that visual styles are required for this functionality.

Have a great weekend!

Nope -- I was setting the icons and then setting the listview's Sorting property. Moving the SetSortIcon call to immediately precede the Refresh fixed the problem.

Would you like the VB solution? Other than being in another lanague, it also has a couple of extremely minor improvements (a bug fix with previouslySortedColumn/previouslySortedColumn and using Delegates to give reasonable names to the SendMessage calls).

Nice, but using this code removes the column header text, only leaving the sort indicator. How can I get the sort indicator AND the text?

@gewe Make sure hdItem.fmt has HDF_STRING and either HDF_SORTUP or HDF_SORTDOWN. That should allow you to display both the text and the sort icon.

Can u tell me how to move the sort icon to the border of the column... The code is working fine...

Thanks a lot Bro.....

Thank you for the contribution. I would never have solved it if I hadn't stubled upon it here!
