I must use this, because i use WordBreak in the Caption. If i not use this event each row becomes to heigh. I need only 17 pixels, the default becomes 22.

But the lost time doesn't matter !

MeasureRow is fired one per row, BeforDrawRow is fired 2 times for each Item !

I use also CustomDraw !

 

So i get many events but this works very fast for me.

 

In an other test before i use the virtual mode with ADO-Recordset.

THIS was the main performance break !!!

Each access to the Recordset.AbsolutePosition makes problems.

 

To understand:

Each DrawBeforeRow (for each item), i set the AbsolutePosition.

Each DrawItem set the AbsolutePosition.

 

The reason was, that DrawBeforeRow and DrawItem are not fired consistently (eg. first visible row, than last visible row, than each row and than the items).

 

The setting of AbsolutePosition and the question of that property takes the same time !!!

 

So now i don't use virtual mode and fill the entire recordset to the report.

 

I have done a measurement:

Filling up 10.000 lines with 20 columns in 3 Seconds without access the AbsolutePosition (count by myself).

But with access of AbsolutePosition i need about 70 seconds !!!

 

I don't find anything in the internet why this property takes a long time.

It's also independent if the recordset is connected with ClientCursor or build by my own.

 

Thanks for sharing

 

Will this event be raised everytime the RC contents changes? Just like the BeforeDrawRow event? If so, I will have my concerns about using this. It's taking alot of CPU time already

 

 

MyReport.SetCustomDraw xtpCustomMeasureRow

 

Than you get for each Row a MeasureRow-Event.

 

You can not change the RowHeight itself, it will be sized by its contents if you set wndReportControl.PaintManager.FixedRowHeight = false  

How can I change by code, the rowheight in the reportcontrol?
