     <asp:FormView ID="FormView1" runat="server"  OnDataBound="FormView1_DataBound">
                        <ItemTemplate>
                              <asp:Image ID="Image3vi" Text='<%#Eval("ImageName1")%>' runat="server" src='<%#getSRCDD(Container.DataItem)%>  ' Width="100%"  class="imagepost img-rounded" alt=""  ImageUrl='<%# ("../UserImage/") %>'/>
                              <video id="my-player" class="video-js" controls="controls" preload="auto"  data-setup="{}" style="width:100%; height:323px">

                <ItemTemplate>
                    <table border="0" cellpadding="0" cellspacing="0">
                        <tr>
                            <td>ID:
                            </td>
                            <td>
                                <asp:Label ID="Label1" runat="server" Text='<%# Eval("Id") %>'></asp:Label>
                            </td>
                        </tr>
                        <tr>
                            <td>Name:
                            </td>
                            <td>
                                <%# Eval("Name") %>
                            </td>
                        </tr>
                        <tr>
                            <td>Description:
                            </td>
                            <td>
                                <%# Eval("Description") %>
                            </td>
                        </tr>
                    </table>
                </ItemTemplate>
</asp:FormView>

protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {
                DataTable dt = new DataTable();
                dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id", typeof(int)),
                    new DataColumn("Name", typeof(string)),
                    new DataColumn("Description",typeof(string)) });
                dt.Rows.Add(1, "John Hammond", "Works as a scientist in USA.");
                FormView1.DataSource = dt;
                FormView1.DataBind();
            }
        }

        protected void FormView1_DataBound(object sender, EventArgs e)
        {

            Label Label4 = (Label)FormView1.FindControl("Label1");
            string label4 = Label4.Text;
            if (label4 == "1")
            {
                Label4.Style.Add("display", "none");
            }
            else
            {
                // do nothing
            }
        }

    Result:
