  I have a FormView that displays user contents, both data, image and video. But if user content doesn't contain video content in database the video handle is displayed on FormView, so how do i hid video or image control if image or video doesn't exist?.

  html

   <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">
      <source src="<%# Eval("Path") %>" type="video/mp4">

                      <source src="<%# Eval("Path") %>" type="video/webm" >
      <div class="vjs-no-js">

  Hi Skyformat48,

  According to your description and code, i make a sample through your needs, please check the following sample code:

  Sample Code:

  <asp:FormView ID="FormView1" runat="server" OnDataBound="FormView1_DataBound">
                  <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
              }
          }
