[RESOLVED] Adding Image to ListView - Problem

[rpc86]

Hi guys,

I'm working on a dynamic listview from Sql server 2k database, and I need to add image on it. I already added ImageList control to my form, and set the ListView property as LargeIcon, SmallImageList as the ImageList.

I do not know how to add image on the listview. Here is my code and I dont know what's wrong with it, though it shows the data from database, only the image is not appearing:

Public Sub PopulateListView_Images(ByVal lv As ListView, ByVal cmd As SqlCommand, ByVal myImageList As ImageList)
        Dim da As New SqlDataAdapter
        Dim ds As New DataSet

        ds.Reset()
        da = New SqlDataAdapter(cmd)
        da.Fill(ds)
        'Fill Method
        lv.Columns.Clear()
        lv.Items.Clear()

        lv.SmallImageList = myImageList

        'Fill Listview
        Dim c As DataColumn
        For Each c In ds.Tables(0).Columns
            'adding names of columns as Listview columns				
            Dim h As New ColumnHeader
            h.Text = c.ColumnName
            h.Width = 60
            lv.Columns.Add(h)
        Next
        Dim dt As DataTable = ds.Tables(0)
        Dim str(ds.Tables(0).Columns.Count) As String

        'adding Datarows as listview Grids
        Dim rr As DataRow
        For Each rr In dt.Rows
            For col As Integer = 0 To ds.Tables(0).Columns.Count - 1
                str(col) = rr(col).ToString()
            Next
            Dim ii As New ListViewItem(str)
            lv.Items.Add(ii)
            'showing the number of records still added
        Next
    End Sub

In this code, only the data is showing but no image. I tried adding

lv.Items(0).ImageKey = 0

but it does not work too.


This is now my table structure:

SubModule            Char          100
Icon                     Int               4

Only the SubModule name appears. What I need is that the value of "Icon" (0,1,2,3) is dynamic to lv.Items(0).imagekey

Please help me on how to add image on the listview. You can advice me also if my code above is wrong.

Thank you.

Ive never really tampered with listview that much except to add rows and such for an extraction process but these links might be of use to you:

First up, an ImageList is not a control. It's a component.

A ListView gets all its Images from the associated ImageLists. To add a new Image to the ListView you must first add it to the appropriate ImageList, then set the ImageIndex or ImageKey of one or more items to display that Image.

Well actually you will need to add your images to the Imagelist first and then set it to the Listview and when adding Listview items you can specify the image index to use for each item.
