The problem arose after I moved ScriptManager to the main page - and only when I used pages without update panels.

Solved by moving the ScriptManager tag immediately before the content area of ​​the main page.

This problem is solved by setting EnablePartialRenderingto false ScriptManager.

ScriptManager1.EnablePartialRendering  = false;

In the OnInitevent of the page where it is used rsweb:ReportViewer. If you want to enable for another page, set to true on the main page OnInit.
