您好，



我看到了RPTV发票你没有做任何明确的数据源。如果你第一次清除数据源，它仍然有效吗？



我认为在设计时某些东西不能像你向项目中添加一个DataSource和没有数据的报告已清除的源正在使用设计时数据源。

Hello,

I see that for RPTVinvoice you don't do any clear of datasources. It is still working if you first clear the datasources?

I think something at design time is not working well like you add to your project a DataSource and the report without data sources cleared is working with the design time datasource.
