c# - 在报表查看器的行中显示唯一数据

Question

首先请原谅我的英语，我想使用报表查看器 asp.net 2010 显示报表，将数据绑定到报表查看器并显示报表数据效果很好，但是在组中隐藏重复数据不起作用，我确实右键单击文本box & F4 设置用组名隐藏重复项。它只会隐藏连续重复的行数据

 for example 
    Data in the column is 
    <br />Employee
    <br />Employee
    <br />Employee
    <br />Employee
    means it'll show only one time. if it is like 
    <br />Employee
    <br />Department
    <br />College
    <br />Employee
    <br />Department
    <br />College
    means it'll display same format as above.
    & here also i need get unique data in the group.
<br>
Why am asking this means i can't apply distinct in query because it is Many to many relationship query, for that i need to get uniqueness in report only please help me thanks in advance.

Answer 1

我最近不得不做这件事。rdlc 有一个叫做行组的东西。我相信这就是你想要做的。

Answer 2

我建议您从查询中进行优化，而不是在报表查看器中尝试。当我们考虑查询时，您可以使用“GROUP BY”而不是“DISTINCT”删除重复项。希望这可以帮助。
