本地报道问题（rdlc）VS 2017 [英] Problem with local reports (rdlc) VS 2017
问题描述
大家好，
我的本地报道存在问题。会发生什么，这是第二次，在设计器中修改报表后，报表查看器中的报表无法再加载。 （尚未为数据源提供数据源实例"Datasource_Name"。
其中Datasource_Name只是我的数据源的名称。
如果我查看报表设计器，报表数据窗格中有一个数据源和一个数据集。如果我右键单击Tablix，数据集名称就会被填充。
如果我去我的单击表单，单击小箭头，选择一个报告，然后选择
选择数据源， 报告数据源和
数据源实例为空。重新绑定数据源
也不起作用。
如果我使用向导创建新报告，并且在报告查看器中选择新创建的报告，一切都很顺利。我可以在设计器中更改报告并再次运行它没有任何问题。但是在突然做了很多更改之后我得到了上面描述的
错误我不能再运行我的报告。这非常烦人，因为我花了很多钱创建它们的时间，我没有线索去除错误或解决报告数据源和数据源实例问题。
任何想法？可能是一个损坏的XML文件？
问候，

Hi all,
I have a problem with local reports. What happens is, and this is the second time, After modifying a report in the designer, the report can't be loaded anymore in the report viewer. (A data source instance has not been supplied for the datasource "Datasource_Name". Where Datasource_Name is just the name of my Data Source.
If I look in the report designer, there is a data source, and a dataset in the report data pane. If I right click on the Tablix, the Dataset name is filled.
If I go to my form, click the small arrow, select a report, then select Choose Data Sources, the Report Data Source and the Data Source Instance are empty. The Rebind Data Source does not work either.
If I create a new report with the wizard, and choose the newly created report in the Report Viewer, all went fine. I can change the report in the designer and run it again with no problems. But after making a lot of changes suddenly I get the error described above and I can't run my report anymore. This is very annoying because I spent a lot of time creating them, and I don't have a clue to get rid of the error or solve the Report Data Source and Data Source Instance problem.
Any Idea's? Maybe a corrupt XML File?
regards,
Mark
