How to update dataset in rdlc parameters

But after making a lot of changes suddenly I get the error describedДЄbove and I can't run my report anymore. I can change the report in the designer and run it again with no problems. If I create a new report with the wizard, and choose the newly created report in the Report Viewer, all went fine.

If I go to my form, click the small arrow, select a report, then selectД¬hoose Data Sources, the Report Data Source and theДata Source Instance are empty. If I right click on the Tablix, the Dataset name is filled. If I look in the report designer, there is a data source, and a dataset in the report data pane. Where Datasource_Name is just the name of my Data Source. (A data source instance has not been supplied for the datasource 'Datasource_Name'. 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. After you create a dataset, you can configure the properties in the Dataset Properties dialog box.I have a problem with local reports. To create or edit an embedded dataset, use the Report Data pane. Embedded datasets are useful when you want to create a query that has no other dependencies and that you do not need to use for multiple reports. Use an embedded dataset when you want to get data from an external data source to be used only in one report. The actual field collection is whatever the current query in the definition returns.

To update, click Refresh Fields in the Dataset Properties dialog box. The field collection is static based on the query at the time you added the shared dataset to the report. PropertyД¬onfigure the query, including defining it as expression.Д¬onfigure parameters that are not marked Read Only in the definitionД¬annot view or change dataset filters that are part of the definitionД¬alculated fields are not part of the dataset definition The following table compares the properties that can be configured for the definition of the shared dataset on the report server and the instance of the shared dataset in the report definition. You can override other data options and add filters. In this view, you cannot change the query except to add fields. From a wizard or from the Report Data pane, browse to the report server and select the shared dataset to add to your report. To add a shared dataset to your report, open Report Builder in Report Design View. For more information, see Shared Dataset Design View (Report Builder). In this view, you can build a query and set all dataset options. You can also browse to the report server and edit and existing shared dataset. You can save it to a report server or SharePoint site to share with other reports. To create a shared dataset, use Shared Dataset Design View. In Report Builder, you can do the following: You cannot browse to a report server and select a shared dataset to add to your report. In Report Designer, you can create shared datasets as part of a report project, and control whether to deploy them to a report server. Shared datasets make data access easier to manage, and help to keep reports and the datasets they access more secure and more performant. You can optimize a query or cache query results to benefit report performance. We recommend that you use shared datasets as much as possible. For example, a report server administrator might update the query to take advantage of improved indexing or other query performance optimization. Shared datasets are stored on the report server and managed separately from reports or shared data sources. Use a shared dataset to provide a query that can be used by more than one report. You can create and modify paginated report definition (.rdl) files in Microsoft Report Builder, Power BI Report Builder, and in Report Designer in SQL Server Data Tools.
