• After more than 30 years running websites and forums I am retiring.

    I have made many friends through the years. I will cherish my time getting to know you. I wish you all the best. This was not an easy decision to make. The cost to keep the communities running has gotten to the point where it's just too expensive. Security certificates, hosting cost, software renewals and everything else has increased threefold. While costs are up ad revenue is down. It's no longer viable to keep things running.

    All sites will be turned off on Thursday 30 November 2023. If you are interested in acquiring any of the websites I own you can Email Schwarz Network.

VB.NET ListView scroll - rowheight not fixed


Feb 15, 2012
Hi! I'm have been converting old VB6.0 project to VB.NET (2008) and now I'm struggling with ListView component. ListView Events are coming clearer now and I managed to read a huge amount of data (96.000 rows) from textfile to ListView with 6 subitems. All rows are build up nicely, but when I'm scrolling down the rows slowly, through scrollbar (clicking bottom arrow), rowheight is reduced to about half in first 20-30 rows below components upper row??? When I'm using PageDown or scrolling faster (dragging from scrollbar), everything is ok. And when I click to blurred row, it is refreshed and rowheight returns to normal. This didn't happen in VB6.0. Is there any Event, where I could use "lstView.Refresh()" or something to avoid this? Can't advise people to use PageDown only, when scrolling!!!
