a form with a netwebbrowse and a file upload button

[MikeR]

I have a netwebform
it has a netwebbrowse and an upload button
when the user presses the upload file button a new record is added to a file in the above browse
i refresh the browse and the browse displays the new record as well
all cool.....

however if you sort the browse using the sort tabs and the search entry field is on screen
when you upload the file even if you typed nothing in the search entry field when the browse refreshes
the browse shows no records until you use the clear button to I presume clear the filter
however the filter looks empty in the form
1. how do i stop this
how can i clear the filter programmatically or how do i get the filter input field to dissapear
once you have clicked on the column headings the filter always appears.
