Hi friends,

I have a problem with showing data from table.


I have TDataSource with dataset TVirtualTable.

My DBGrid is connected to this datasource.


I'm using DBGrid.Style=stUserDefined with CustomDrawCell procedure which it's not firing !! (in this procedure I have DefaultDrawing:= true)



1/ in OnFormShow event I'm opening this table (if not tbl.Active then tbl.Open) a cleaning it (tbl.Clear)

2/ I send a few rows in table, it's visible on DBGrid

3/ I close the form

4/ next time I open the form (so tbl could be cleaned) and try to send another data, grid is showing data sended in step 2

5/ grid.datasource.dataset.refresh not working

6/ grid.Invalidate / grid.Repaint not working


Can someone help me ?

Hello TomasB,


Maybe you need to enable “custom” layer too inside the column. For example:

Send us applications made with our components and we will submit them on: www.bergsoft.net/apps.htm. Link to this page will be also set on home page too.
