i have a list view :

<asp:ListView ID="ListView1" runat="server">
           <ItemTemplate>
                 <asp:ImageButton ID="ImageButton1" runat="server" />
           </ItemTemplate>
 </asp:ListView>

and i have the link of the images in vb:

Dim dirInfo As string="D:\rbi\images\emoticons\"
  Dim filenames As List(Of String) = dirInfo.GetFiles().[Select](Function(j) j.Name).ToList()


i'm getting the link and the filenames from the directory not from a database...so how can i bind these links in the list view to show all the images?

Give this a look and see if it becomes a little clearer what you need to do.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim dirInfo As String = "c:\path\to\files\"

        Dim di As New IO.DirectoryInfo(dirInfo)
        Dim diar1 As IO.FileInfo() = di.GetFiles()
        Dim dra As IO.FileInfo

        Dim lvData As New List(Of FileObject)
        Dim ctr As Int32 = 0 ' used for FileID (optional)

        'loop all the files in the specified directory
        For Each dra In diar1
            lvData.Add(New FileObject With {.FileID = ctr + 1, .FileName = dra.Name})
        Next

        ListView1.DataSource = lvData
        ListView1.DataBind()

    End Sub

    Public Class FileObject
        Private _fileName As String
        Public Property FileName() As String
            Get
                Return _fileName
            End Get
            Set(ByVal value As String)
                _fileName = value
            End Set
        End Property
        Private _fileID As Int32
        Public Property FileID() As Int32
            Get
                Return _fileID
            End Get
            Set(ByVal value As Int32)
                _fileID = value
            End Set
        End Property
        ' additional properties as needed, file size, etc...
    End Class
