I have a sample attached to show the problem. I want in the report (created a runtime) to use more than one report datasource. I create a databand and connect this with a TFPReportObjectListData object. Each TFPReportObjectListData object works. But i want to have the data of the first, then the data of the other object. But i am not able to combine this two Data in one Report. *--------------------* DataBand := TFPReportDataBand.Create(p); DataBand.Name:= 'DBBand01'; DataBand.Layout.Height := 10; DataBand.Data:= lReportOLData1; // First Data !!!!! This is shown Memo := TFPReportMemo.Create(DataBand); Memo.Layout.Left := 5; Memo.Layout.Top := 0; Memo.Layout.Width := 60; Memo.Layout.Height := 5; Memo.Font.Name := defaultFont; Memo.Text := '[InfoA] - [ValueA]'; DataBand2 := TFPReportDataBand.Create(p); DataBand2.Name:= 'DBBand02'; DataBand2.Layout.Height := 10; DataBand2.Data:= lReportOLData2; // Second Data !!!!! This is not shown Memo2 := TFPReportMemo.Create(DataBand2); Memo2.Layout.Left := 5; Memo2.Layout.Top := 0; Memo2.Layout.Width := 60; Memo2.Layout.Height := 5; Memo2.Font.Name := defaultFont; Memo2.Text := '[InfoB] - [ValueB]'; *--------------------------* Any Hint for this problem to solve ?
This is not supported as you write it.You can have multiple datasources, but only 1 data band. If you need multiple data bands, you'll need to use master-detail.
If you want to use the second dataset in a memo expression, you must add it to the reportdatasets: lReportOLData2.name:='Data2'; YourReport.ReportData.Add(lReportOLData2); and in memo2 (which you must place somewhere else): Memo2.Text := '[Data2.InfoB] - [Data2.ValueB]'; I can't advise you on what bands you must place memo and how to advance the 2nd data list, because for that I would need to know the expected layout. By the way, in if Assigned(rptExporter) then FreeAndNil(rptExporter); etc. The If Assigned() is not needed. FreeAndNil (or more accurately, Free) will already check this for you. Michael.
