Hello Hu Wang,

I am sorry to hear about the issue you encountered when deploying the report and I will work with you to help you resolve it.

As you mentioned, there is "No page to display" message, when you deploy the report in the viewer. This could mean that there is something wrong with the connection string or data, but since there is no content to display, we don't see the actual problem. Please set the property "SkipBlankPages" to False and deploy the report once again. Let me know what happens and if there are any new errors.

It can also be helpful, if you install the Fiddler Jam extension then generate a log and share it with me. This will give me a better understanding of what is happening.

I remain available to continue our discussion and advise you further.

Regards,
