How to select correct dataset with more forms
Hello,
I'm having a hard time controling which frxDBDatset the report shall use.
My report inheriteds from as master-report, containing some application defaults informations
for the reports, such as companyname, time of printing, etc.
I am having a form used as a report-template-form (baseform) containing a frxReport on the form.
In a form, inherited from the report-template-form (reportform) I am adding a frxDBDataset
connected to a memory dataset (memdatset) containing the fields used for the report.
The memory dataset is filled dynamic with data before showing the report.
The form allso contains some edits for user input of values needed to generate the report data.
When I need a report containing all of my data, the memdataset is filled in one way.
If I want a periodical data report, the memdataset is filled in another way, containing
less data.
The two reports is contained within separated forms, created as MDI forms.
The EngineOptions.UseGlobalDatasetList = false, usning EnabledDatasets.Add(frxDBDataset1) before
loading the report from a file.
Heres what happens -
1. Runs the periodical report from the first form, the report shows only the periodical data, correct.
2. Runs the full data report from a second form, the report show all the data, correct.
3. Runs the periodical report again from the first form, now show all the data, fail!
4. Destroing the second form, an run the periodical report again from the first form show
only the periodical data, correct.
I can not figure out how the make this work correct.
