    Hallo Telerik Team,

    I would like to know how I add a list of images to a ListView as Icon View. The path images are in a List<string> and they are into:
    C://Documents/Pic/.
    How can I do that? The images paths are saved in a dataTable in a database.

    Thank you very much.

    Best regards,

    Alfonsina Mello

    Hi Alfonsina,

    Thank you for contacting us.

    You need to iterate through the paths and create items with that image:
    foreach (string fileName in files) // files is List<string>
    {
        ListViewDataItem item = new ListViewDataItem();
        item.Image = Image.FromFile(fileName);
        this.radListView1.Items.Add(item);
    }

    I hope this helps. If you have any other questions, feel free to write back.

    Hello Alfonsina,

    You should not lose the selection highlight when your items have images assigned unless the images are overlaying the background. Please make sure your images have a transparent background. If you continue experiencing difficulties, please open a new support ticket and attach a project which demonstrates the issue. This will let me investigate it and provide you with further support.

    Do not hesitate to contact us if you need further assistance.

    Hi, this works, but how can I strech the Image ? there is no a strech true, or item.Image.Strech property, I use aligment, but it doesn't work in 2013 q3 tha I am testing, in 2013 q1, it works,
    here is my code:

                ListViewDataItem item = new ListViewDataItem(e.fileName);
                item.Text = e.fileName;
                item.ImageAlignment = ContentAlignment.TopCenter;
                item.TextImageRelation = TextImageRelation.TextBeforeImage;

                
                item.TextAlignment = ContentAlignment.BottomCenter;

                Image img = Image.FromFile(e.fileName);
                
                              
                radListViewMedia.Items.Add(item);

    Hello Oscar,

    Thank you for writing. 

    To make an image stretch, you should use the VisualItemFormatting event and set the VisualItem's ImageLayout property:
    void radListView1_VisualItemFormatting(object sender, ListViewVisualItemEventArgs e)
    {
        e.VisualItem.ImageLayout = ImageLayout.Stretch;
    }

    I hope this helps.
