Question

We are getting the error "933.900146484375 is not a valid value for Int32." while using our application in edge.

We get the error when we choose the value from RadTreeView control in our application.

The application is ASP.net application using .net Framework 4.6.1

The RadTreeView holds categories. There are more than one level in the same control to show main category, categories under main categories and sub categories after that.

We get the error when we choose the third level. However we do not get the error in Google chrome and Mozilla Firefox.

The number in the error message varies when we choose a different category.

However we get the same error when we choose the same category.

Please find the attached screenshot.
