I am using the text box search from list view controls. It gives me error sometimes not always "The supplied entity "TestModule.Design" does not belong to list view data source". If I refresh the page the error gone and its works perfectly. Its also not logging anything about the error in console that's why I am not able to solve this. Can anyone have any idea about this problem? Thanks & Regards Bhanu Chauhan
In my experience, this sometimes happens when navigating through pages with textbox and listviews, and the listviews have the same name i.e. listView1. When adding a unique name to the listView the errors disappeared. Maybe worth a try.
