I want to populate GridView below with images:

<asp:GridView ID="GrdDynamic" runat="server" AutoGenerateColumns="False">
    <Columns>
    </Columns>
</asp:GridView>

The code below iterates through directory, then I collect image titles and want them to be populated in gridview. code in bold is not working well, gridview is only filled with the last image in list.

List<string> imagelist = new List<string>();

protected void Page_Load(object sender, EventArgs e)
{
    foreach (String image in Directory.GetFiles(Server.MapPath("example/")))
    {
        imagelist.Add("~/example/" + Path.GetFileName(image));
    }
    loadDynamicGrid(imagelist);
}

private void loadDynamicGrid(List<string> list)
{
    DataTable dt = new DataTable();

    DataColumn dcol = new DataColumn(NAME, typeof(System.String));
    dt.Columns.Add(dcol);

    dcol = new DataColumn("NAME1", typeof(System.String));
    dt.Columns.Add(dcol);

    dcol = new DataColumn("NAME2", typeof(System.String));
    dt.Columns.Add(dcol);

    dcol = new DataColumn("NAME3", typeof(System.String));
    dt.Columns.Add(dcol);

    DataRow drow = dt.NewRow();
            dt.Rows.Add();
            dt.Rows.Add();

            **for (int i = 0; i < dt.Rows.Count; i++)
            {
                for (int j = 0; j < dt.Columns.Count; j++)
                {
                    foreach (string value in list)
                    {
                        dt.Rows[i][j] = value;
                    }
                }
            }**

    foreach (DataColumn col in dt.Columns)
    {
        ImageField bfield = new ImageField();

        bfield.DataImageUrlField = NAME;

        bfield.HeaderText = col.ColumnName;

        GrdDynamic.Columns.Add(bfield);
    }

    GrdDynamic.DataSource = dt;

    GrdDynamic.DataBind();
}

how to fill gridview cell-by-cell only with available amount of images?

i know it is easy, i tried various methods like: dt.Rows.Add(list); and some other attempts, but they didn't work. i'm very stupid. i'd be glad for any help.
