I found an issue where I had a webpage that has an AsyncUpload control and a text field. If the user enters text that contains angle brackets with some text between the brackets, the AsyncUpload throws some type of error.
I was able to reproduce this problem in the Telerik demo:
https://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandradasyncupload/defaultcs.aspx?product=asyncupload
Steps:
1. Click "Add new record"
2. In the Image Name field type "test <test.com>"
3. Upload an image file
4. Click checkbox to add record
5. Error occurs.

Hello Loy,
ASP.NET by default does not allow HTML tags in the TextBoxes, see Request Validation - Preventing Script Attacks.
It is possible to disable it I highly advise you against it. Here is a StackOverflow articles showing how to disable it: https://stackoverflow.com/a/8226484/2289769.
