RDLC 报告:将过滤器应用于报告 [英] RDLC Report: Apply Filter to Report

问题描述

我有两个参数 dateFrom 和 dateTo 我想根据这些值过滤我的报告并显示过滤的 total 列的总和报告中的行.

I have two parameters dateFrom and dateTo which I want to filter my report based on those values and show sum of total column of filtered rows in the report.

目前，当我使用表达式 =Sum([total]) 时，它返回数据库中整列的总和，并且不会对表达式应用日期过滤器.

Currently when I use expression =Sum([total]) it returns the sum of whole column in database and it doesn't applying date filter on expression.

问题:如何应用日期之间的总和 dateFrom 和 dateTo 参数像这样的伪代码:

Question: How to apply sum of total between dates dateFrom and dateTo parameter like Something like this pseudo-code:

=Sum(Field!Total.Value) where date between dt_from to dt_to

这是我用来加载展示报告的代码:

Here is the code I use to load show report:

invoice_viewTableAdapter.Fill(this.db_posDataSetInvoice.invoice_view);
reportViewer1.RefreshReport();

推荐答案

您应该对报表的数据源应用过滤器，例如:

You should apply the filter on the data source of your report, for example:

invoice_viewTableAdapter.Fill(this.db_posDataSetInvoice.invoice_view);
this.invoice_viewBindingSource.Filter = "Put your filter here";
reportViewer1.RefreshReport();

假设您有一个 MyDateField 字段，并且您有 DateTime 类型的 dateFrom 和 dateTo.

Supposing you have a MyDateField field and you have dateFrom and dateTo of type of DateTime.

这可以是您的日期过滤器:

This can be your date filter:

String.Format("MyDateField>= #{0:yyyy/MM/dd}# AND MyDateField<= #{1:yyyy/MM/dd}#"
              , dateFrom, dateTo);
