With the latest prerelease I am seeing the following error in visual studio when opening a designer window. The designer does load up fine.

Server cannot clear headers after HTTP headers have been sent.

Hello,

We were unable to reproduce the error. What version of Visual Studio do you use? Does the following error occur on the empty project, where only WebDesigner is put?

Thank you.

I resolved this on our end.

In our page_load we were checking the querystring parameter stimulsoft_webdesigner before running our initial code but the real value was stimulsoft_designerfx, so our call to .Design was being made twice.

Hi Lynn,

Thank you for your feedback, please let us know if we can help you any further.

Thank you.
