ErrorMessage=File size should not be greater than 1 KB. OnServerValidate=CustomValidator1_ServerValidate> protected void CustomValidator1_ServerValidate(object source ServerValidateEventArgs args) { if (fuFile.FileBytes.Length > 1024) // 1024*KB of file size { args.IsValid = false; } else { args.IsValid = true; } }
