Hi,

I am trying to add

Syncfusion.JavaScript.Web.ReportViewer

in my designer.cs file and it is throwing the following

The type or namespace name 'JavaScript' does not exist in the namespace 'Syncfusion' (are you missing an assembly reference?) error

and i see in the .aspx file

it is showing element report viewer is not a known element.this can occur if there is a compilation error or web.config id missing.

Can u please help me on this.
