GetItemMetrics() is called everytime the report control is being painted. In virtual mode the report control doesn't hold or cache any data. GetItemMetrics() is also only called for visible rows.

If the window is deactivated the report control loses the focus, so it needs to be redrawn. Same if the window becomes actived again.

Hello CJ Team,

I am implementing CJ Report control in our application, for that I am referring "VirtualList" sample. In that sample application method GetItemMetrics(..) get the data for each column and row and always get called to paint the cell.

I included GetItemMetrics(..) method it is working fine with the small amount of data but in case of large data it is getting slow due to calling GetItemMetrics(..) for each row even I activate the window.

In simple way, once I set the value for "pItemMetrics->strText" for 1 to 50 rows (those are visible) I don't want set it each and every time even I activate the window. What is the way where I can ensure that the data has already been loaded for the respective row in function GetItemMetrics(..) ?

Thanks,
-Mak
