This article explains you about Binding of DataList to DataView Without Using Database
 

Hi Guys,

Just follow this stepsĀ 

For binding images in data list


 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        If Not Page.IsPostBack Then
            ' bind datalist
            DataListImages.DataSource = GetImages()
            DataListImages.DataBind()
        End If
    End Sub
This function used to get images with out data base connection as

This retrives the images from the specific folder of the system

Private Function GetImages() As DataView
        Dim dt As New DataTable
        Dim dr As DataRow
        dt.Columns.Add(New DataColumn("ImageName"))
        dt.Columns.Add(New DataColumn("ImageFile"))
        ' populate the rows
        Dim dir As IO.DirectoryInfo = New DirectoryInfo(Server.MapPath("images"))
        For Each fi As FileInfo In dir.GetFiles("*.jpg")
            dr = dt.NewRow()
            dr(0) = fi.Name.Substring(0, fi.Name.IndexOf("."))
            dr(1) = "images/" & fi.Name
            dt.Rows.Add(dr)
        Next
        Dim dv As New DataView(dt)
        Return dv
    End Function

To display items in data boundĀ 

 Protected Sub DataListImages_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs)
        If e.Item.ItemType = ListItemType.Header Then
            CType(e.Item.FindControl("ItemsCount"), Label).Text = GetImages.Count.ToString & " items in total"
        End If
    End Sub
In the designing page of aspx use coding as
 

<%# DataBinder.Eval(Container.DataItem, "ImageName")%>

Hence You find the way
