ImageButton inside Datalist

[byka]

I have datalist with imageButton generated from folder with Images. I am trying to change border on clientClick event to indicate that user selected that image. I was able to get click event for image but how to I unselect others images? function ccSelectedImage(e) { { alert(e); e.style.border = "1px solid Red"; return false; } }

    Dim dir As DirectoryInfo = New DirectoryInfo(MapPath("Images"))
    Dim files As FileInfo() = dir.GetFiles()
    Dim listItems As ArrayList = New ArrayList()

    For Each info As FileInfo In files
        listItems.Add(info)
    Next

    dtlist.DataSource = listItems
    dtlist.DataBind()
