    Hi Ashraf007,

    Repeater also has  OnItemDataBound which is like OnRowDataBound,

    Below is my code.

     <asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
           <HeaderTemplate>
               <table border="1">
                   <tr> <td>name</td><td>image</td></tr>
           </HeaderTemplate>
            <ItemTemplate>
                <tr>
                    <td>
                        <asp:Label ID="Label1" runat="server" Text='<%# Eval("name") %>' ></asp:Label></td>
                  <td>
                      <asp:Image ID="Image1" runat="server"   />
                  </td>
                </tr>
            </ItemTemplate>
            <FooterTemplate>
           </table>
                </FooterTemplate>
        </asp:Repeater>

    cs

     protected void Page_Load(object sender, EventArgs e)
        {
            DataTable table = new DataTable();
            table.Columns.Add(new DataColumn("name"));
            table.Columns.Add(new DataColumn("image"));
            table.Rows.Add("tom", "/images/pagination_icons.png");
            table.Rows.Add("jerry", "/images/panel_tools.png");
            table.Rows.Add("pity", "/images/validatebox_warning.png");
            Repeater1.DataSource = table;
            Repeater1.DataBind();
        }

        protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item )
            {
                DataRowView dr = (DataRowView)e.Item.DataItem;
                //   string imageUrl = "data:image/jpg;base64," + Convert.ToBase64String((byte[])dr["Data"]);
                string imageUrl = dr["image"].ToString();
                (e.Item.FindControl("Image1") as Image).ImageUrl = imageUrl;
            }

        }

    The result.

    Just change your code to ,   ListItemType.AlternatingItem , ListItemType.Item both represents  dataitem

     protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item )
            {

     DataRowView dr = (DataRowView)e.Item.DataItem;
            string imageUrl = "data:image/jpg;base64," + Convert.ToBase64String((byte[])dr["Data"]);
            (e.ITEM.FindControl("Image1") as Image).ImageUrl = imageUrl;
               
            }

        }

    Best regards,
