rdlc报告错误-在进行lkocal处理期间 [英] rdlc Report Error - during lkocal processing

问题描述

我正在尝试在vb.net中做一个简单的报告

我已完成以下
我有一个带有报表查看器的表单(我从中删除了所有代码-两行)

我有一个带有文本框"Hello world"的报告
我从启动表单中按如下方式调用该报告

Hi I am trying to make a simple report in vb.net

I have done the following
I have a form with a report viewer (I have removed all the code from it - two lines)

I have a report which has a text box "Hello world"
I call the report as follows from my startup form

dim objFrm as new frmViewer
objfrm.ReportViewer.localreport.reportpath= "report1.rdlc"
objfrm.ReportViewer.refreshreport()
objfrm.showdialog

该报告工作正常.

然后，我向报表中添加一个表(tablix)，并将其绑定到现有数据源.我检查了该数据源是否正常工作(并且已经删除并读取了几次)
我在表[Client]中添加了一个字段-该字段显示在下拉选择框中

现在，当我运行报告时，出现以下错误:
尚未为数据源"dataset1"提供数据源实例

不管我做什么，我都无法使报表立即运行.

任何帮助将不胜感激

问候
Ants

The report works fine.

I then add a table (tablix) to the report and bind it to an existing datasource. I have checked that this data source works (and I have deleted and readded it a couple of times)
I have added one field to the table [Client] - this appears in the drop down selection box

Now when I run the report I get the following error:
A data source instance has not been supplied for the data source "dataset1"

No matter what I do I can not get the report to now run.

Any help would be much appreciated

Regards
Ants

推荐答案

如果您希望手动设置数据源，请查看我对本文的回答

我已经在那解释了.
我还制作了一个小示例项目，您可以在此处下载

只需记住在报表查看器控件中选择报表后，删除设计器生成的数据绑定(数据表和绑定源)

If you wish to manually set the data source, check my answer to this post

I''ve explained it there.
I''ve also made a small example project which you can download here
http://www.yourfilelink.com/get.php?fid=598973

Just remember to remove the designer generated data-bindings (data table & binding source) after you pick a report in the report viewer control
