try this. :)

C#

string NameString = Path.GetExtension(FileUpload1.FileName);

           if (NameString == ".xls" || NameString == ".xlsx")
           {
               //Your code

           }
           else
           {

               //Select Excel File only
           }

Solution 2

There is no direct method. But you can call one JavaScript function onchange event and inside that event validate the extension.

Refer - FileUpload - Filter File Type/File Extension/File Size[^]

You can also try this method[^], which suggests to use RegularExpressionValidator.

There is no other way out for restricting file types. So, the only option is to validate.
Do that.
