Dynamically adding controls to a panel within a data repeater

Question

I have a Data Repeater to which I need to add x number of images depending on their existence in the database.

I need the images added within hyperlinks for Javascript functionality. In order to dynamically add the hyperlinks and images I have placed them within a panel in the data repeater and am adding them in the ItemDataBound event.

The problem is that only the first image is being written to the datarepeater.

Protected Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs) Handles myDataRepeater.ItemDataBound
    Dim myPanel As Panel = e.Item.FindControl("pnlImages")
    Dim myLink As New System.Web.UI.WebControls.HyperLink
    Dim myImage As New System.Web.UI.WebControls.Image
    Dim myProperty As String = Request.QueryString("ID")

    Dim dirInfo As New DirectoryInfo(Server.MapPath("~/ftp/images/"))
    Dim fs_infos() As FileInfo = dirInfo.GetFiles("*" + myProperty.Substring(1) + "*")
    For Each fs_info As FileInfo In fs_infos
        If fs_info.Name.Substring(8, 1) <> "P" Then

            myLink.ID = fs_info.Name
            myLink.NavigateUrl = "~/ftp/images/" + fs_info.Name
            myLink.Attributes.Add("onClick", "return hs.expand(this)")
            myLink.Width = 90

            myImage.ID = "img" + fs_info.Name
            myImage.ImageUrl = "~/ftp/images/" + fs_info.Name
            myImage.Width = 80
            myImage.Height = 60
            myLink.Controls.Add(myImage)
            myPanel.Controls.Add(myLink)
        End If
    Next fs_info
    fs_infos = Nothing


End Sub 

Any ideas as to what I am doing wrong - or a better way of doing things?

Answer 1

You create just one Link and one Image object and use it for each iteration. Move the dims of myLink and myImage into the if statement and everything should work.
