AdvDBGrid not painting some rows

VCL TMS VCL UI Pack
1

Hello,

I'm using Delphi XE3 and AdvDBGrid connected to an MS-SQL DB.

PageMode is set to true, DataSetType set to dtSequenced. 
When scrolling with mousewheel some rows are not painted or painted on half. If i click on the rows with this problem, the rows are painted correctly. Anyone having this issue ?

Thanks.

Does it make a difference when you set DataSetType = dtNonSequenced?

Yes, but then the vertical scroll bar position is not synced with the dataset.

Seams that changing the Wheelncrement to 1 will correct this.
