在报表查看器中显示已添加的列c＃ [英] Display Added Columns at Report Viewer c#

问题描述

大家好，这是我第一次参加这里，我一直在这个网站上阅读，我真的给你留下了深刻印象的人，开发者你是有史以来最聪明的生物，

我是民用的工程师，不过我是语言编程粉丝俱乐部之一

但我真的遇到了问题，我用c＃和sql数据库创建一个windows表单应用程序

at the运行时，我能够在datagridveiw中添加/删除列，并获得更新，以便当我重新打开应用程序保存数据时，我还能够获得由向导静态设计的报表查看器，但是只显示在设计阶段而不是运行时添加的列，

i有一个很大的断裂问题是如何显示数据发生的修改（添加列或删除一个）在报告查看器中的运行时



例如（我设计报告有三列名称，LastN ame，money，并在运行时成功获取报告，然后我在运行时添加一些新列说（年龄，国家）

但是当我试图获取报告时我只有3列（名称，姓氏，金钱）更新的行但不是列



请这是重要的

Hello Everyone , This is my First participation here, I have been reading from this site for while and i am really impressed by you people, Developers You are The Smartest creatures ever,
I am civil Engineer , However i am one of languages programming fans club
but i am really having a problem in this , I create a windows form application using c# and sql database
at the run time, i was able to add/delete columns in the datagridveiw ,and get that updated so that when I reopen the application the data are saved, i also was able to get a report viewer that i design statically by the wizard, however it only shows the column that was added in the design phase not the run time,
i am having a big fractured problem which is How can I display the modifications that occur to the data ( adding column or delete one ) at the run time in the report viewer

For example ( I designed the report to have three columns Name , LastName, money, and get the report successfully at the runtime,then I add some new columns say (Age,Country)
at the run time but when I tried to get the report I only got 3 columns (Name, LastName,Money) with updated Rows But not column

Please This is SO important

推荐答案

尝试一件简单的事情，在添加Age和Country之后，停止您的应用程序，重新绑定数据源（刷新它，以便它将带来更新的数据列）并尝试运行它。

try one simple thing, After adding Age and Country, stop your application, rebind the data source(refresh it, so that it will bring updated data column) and try to run it.
