Error in IIS 8.5 integrated mode

[Tamil N]

Hi,

We are in the process of migrating IIS 6 ASP.Net web apps to IIS 8.5, various Syncfusion 10.3 controls are used. I am not able to find correct handlers for this controls to add in web.config. Due to other reasons we can not run this in classic mode either.

Is it possible to run this version of Syncfusion ASP.Net in integrated mode?

Hi Tamil, 

Thank you for contacting Syncfusion support. 

The Classic control needs the handlers to be added in the Web.config file to render controls like Captcha, UploadBox, etc., So we suggest you to add Handler in <httpHandlers> section of <system.web>. When the application is run directly from developer environment, it’s enough the handler are added in <httpHandlers > section of “system.web” tag but while deploying it from IIS server you will need to add the handler in <handlers> section of “system.webServer” tag also. Also there may be issue on registration of  httphandlers sections in IIS while using Integrated pipeline mode. So we suggest you to set the validation element’s validateIntegratedModeConfiguration attribute to false in order to avoid errors. If still the issue persists, could you please share the defect sample or screenshots? So that we could provide you a better solution. Please refer the following code snippet.
