i need a list control which use a dialog as item.

I dont know if this will work, but take a look at embedding dialogs in things like tab controls. There is an article here[^] which does it simply.
Then take a look at an article that embeds something else in a listctrl. A pretty simple one can be found here[^].

Then just change the row height and you're set.

This seems rather odd for an UI. If you just want to show a read only dialog there, you may not need to embed a dialog. Instead use custom drawing/painting to show all the data you want to, and make it look like a dialog.

On the other hand if you want to get an editable dialog in there, perhaps you should be looking at using a more advanced control such as an MFC grid control. And then customize the rows to look like actual dialogs using Grid-specific embeddable child controls. That would be a more common approach to this sort of problem.

Thanks everyone !
I decide to use the Rollup Control.
Although It is not as suitable as i think,but if i modify it ,it will be ok. :-\
