Loop not appering within a multiline textbox

hi

A weird thing is happening! I'm trying to populate a textbox from a while statement and it catches only the last record from a text file. And if I put a Response.Write into the loop then records are normally displayed. (I properly have to add that content into a textbox to edit it after)

any idea?

any help will be greatly appreciatedi've found, thanks:

textbox.Text =textbox.Text + strLine
