Scrolling in Grids

[tbarone]

I am using Delphi 5. Everytime I use any type of a grid I cannot get the scrollbar on the grid to work right. I cannot seem to get it to work like a real scroll bar. When I move to the second record the bar moves to the middle and the bar stays in the middle until i get to the last record? Is there any code I can use to fix this or a property I need to set?

Thanks,
Tony

Also, It is not a regular scrollbar, it is a infoPower 3000 wwDBGrid

This is apparently a problem with delphi. We have had the same problem, and I was curious to see if the borland.public boards had an answer. It appears that twwdbgrid is a direct descendant of delphi's tdbgrid (as expected), and that delphi's tdbgrid works that way on purpose. According to the posts on the borland boards, some dataset types do not include a recordcount property, and it can be expensive (performance-wise) to constantly retrieve it. I don't buy this entirely, since you would think it would work fine if the dataset has a recordcount (in BDE or ADO type operations).

Our initial attempt to solve this problem was to drop a TScrollbar on top of the grid scroll bar and control that, but it was a pretty time-consuming problem to handle all the possible user operations, and we gave up. We just provide our users with the poor quaility scroll bar that we get with infopower.
