Report doesn't render and issues loading the report

[Vic Alfred Inting]

The sample solution returns this after a POST to PostReportAction:

{"isReportLoad":true,"parameters":[],"dataSources":null,"dataSets":["AdventureWorksXMLDataSet"]}

And the sample loads the report properly. Now, in my implementation I get this when I POST to my PostReportAction endpoint:

{"isReportLoad":false,"parameters":[],"dataSources":null,"dataSets":[]}

I don't know why report doesn't load and why a data set is not set. I manually defined the data source and got no errors there. No errors are reported anywhere, except the control displays this:

"Report Viewer encountered some issues loading this report. Please click here to see the error details"

And when I click on here, it just opens a pop-up and says "Report Loaded:[object Object]". Can anyone help me please?

Hi Vic,

Thanks for using Syncfusion Products.

The mentioned error occurred due to all the required Report properties are not set in ReportViewer. We request you to set the processing mode(Local for RDLC and Remote for RDL/SSRS) of the report, add Datasources collections if your Report is RDLC and set the Parameters if the report contains ReportParameters. Kindly refer our online documentation for more details.

If you still face any issues, could you please share sample ReportDefinition of your report?, it will be helpful for us to provide a solution earlier.

Please let us know if you need any further assistance on this.

Hi,

I am experiencing the same issue.

The application works perfectly on my machine (the one it was developed on).

Having transferred the deployed filed on other computers I got the mentioned error, even with a report without DataSource and parameters.

I have tried this on a machine with Windows XP and one with Windows 7 (same as mine) but I just get this error.
