I have a webpart with asp.net control within. I would like to hide some parts of that control, some asp:net panels etc. regarding one of the TextBox's value. The issue is that I don't know to change the visibility of asp:panel wrapper without any postback, and how to refresh page to see the changes on the UI. I was trying to implement TextChanged event but it dosen't work. Can anybody help me, please?
The answer for this question is AJAX. For example asp:updatepanel can be used.
