DBGrid scrolling issue when TBufDataSet has filter set
« on: June 23, 2024, 11:29:01 am »
Hello,

I have a TBufDataSet that displays data from excel sheet. When the entire table is without a filter, the DBGrid scrolls fine for me. But as soon as I set the filter, the data is filtered, but the scrollbar does not go down smoothly, but jumps. It looks like it still keeps the total number of rows regardless of the filter.

I tried searching but couldn't find anything about the DBGrid scrolling and TBufDataSet connection.

That's why I'm asking for help here and thank you in advance.

George

In the DataSet, there is a OnFilterRecord which allows you to reject it.

I don't know if that will solve the problem because I am not a DB expert by any means.
