Hide a row in a grid using ManualBuild

capedica

Hi, i'm evaluating FastReport. I need to know if this action can be done.
I'm filling a table using the manualBuild event, using this code (taken from a demo), to fill a grid where rows are columns:

      DataSourceBase columnData = Report.GetDataSource("TestDataSource");
      columnData.Init();
      // print the first table column - it is a header
      Table5.PrintColumn(0);
      // each PrintColumn call must be followed by either PrintRow or PrintRows call
      // to print cells on the column
      Table5.PrintRows();

      Table5.PrintColumn(1);      
      Table5.PrintRows();
      
      // now enumerate the data source and print the table body
      while (columnData.HasMoreRows)
      {
        // print the table body  
        Table5.PrintColumn(2);
        Table5.PrintRows();

        // go next data source row
        columnData.Next();
      }

My question is: after i've filled the grid, is there a way to detect if a row has all empty values? and a way to hide it?
Thank you

Hi Capedica
Did you tried to use event AfterData for your DataBand?
You can check if all values are null or empty and then set Visible to false if they are all empty.
