I have a SDK form, with many folder items on it ('tabs').
Plus a matrix component, with many columns bound to user datasources.
SBO version is 2007.
I notice that when i set the values of the datasources with.ValueEx the screen (and most notably the folderitems) start to redraw, causing lots of flicker when there are many columns. I did some testing and it very specifically occurs on the setting of .ValueEx , without even calling .SetLineData on the matrix.
This behaviour was not present in SBO2005.
Anyone else noticing this behaviour or knows the cause?
A remedy that works is to wrap everything always in a Freeze/Unfreeze of the form, which reduces the flickering in a one time flicker. This is not a nice solution, since actually nothing should even be redrawn yet, until the .SetLineData of the matrix.
