Hi,

I am new to the ReportViewer (and to all of Syncfusion components). Currently i see into it and try to use ReportViewer to render some of already existing reports in our project. All reports work fine via standard Report Manager in browser.

And i stuck with problem that ReportViewer does not include NULL-values in available values combobox for a parameter which fills from a dataset even when the parameters property "Allow null value" is set.

In attached ZIP i put the very simple project showing the problem, rdl report, rds for values of parameter, and two pictures - one for standard Report Manager rendering the report and second for ReportViewer.

Please, check this and recommend what i need to do to get NULLs available in combobox.

Thanks in advance,

Sergey Salnikov.
