Listview flickering and performance problem


J

James

Hi all,
I have made a derived Listview which can accept the controls as
items in it. Controls that we are using are Buttons in each row and
implemented Grouping with the help of controls(label on panel) . Coz
Inbuilt listview Grouping not supported in OS like window 98.

Although I had used Double buffering
(SetStyle(ControlStyles.DoubleBuffer, true); .. in my Listview) but
still the listview flickers much when we scroll its items. And as
the number of items reaches nearly equal to 18, the performance again
degrades analogically and starts flickering at high level.

I have to made a list view can accept nearlly 100 items as rows
efficiently and without flickering.

if anybody have any views / ideas to sort out this problem will be
appreciated.

Thanks
James

James,

I haven't played with this, but judging from my experiance with common win32
controls I believe that the porformace might degradate as number of child
controls increases.

It will be really helpfull if you could post a sample application that we
can fiddle with, but my suggestion for now is to use a single set of child
controls and move it along withe the focuse.
This way you have small number of child controls and second of all I don't
see the reason why the controls should be visible if the user doesn't intend
to use them.
