1. Between the form tags, add a Label with the following information.
       <asp:Label ID="Label1" runat="server" Text="Content ID: "></asp:Label>
  2. Add a text box for the user to enter the content ID.
      <asp:TextBox ID="txtContentId" runat="server" Width="44px"></asp:TextBox>
  3. From the Validation control menu, add a RequiredFieldValidator control. This validates that something appears in the Content ID box.
      <asp:RequiredFieldValidator ID="rfvContentId" runat="server" ControlToValidate="txtContentId"
            ErrorMessage="Please enter content ID"></asp:RequiredFieldValidator>
  4. Add a couple of breaks for spacing purposes.
      <br /><br />
  5. Add a button to get the content. We will set the button click event in the code behind.
      <asp:Button ID="btnGetContent" runat="server" Text="Get Content" />
  6. Add a couple of more breaks for spacing purposes.
      <br /><br />
  7. Add a results label where the content will appear. This also serves as a place to display an error if necessary.
      <asp:Label ID="lblResult" runat="server" Width="175px"></asp:Label>

   Protected Sub btnGetContent_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnGetContent.Click

       Dim contentApi As New Ektron.Cms.API.Content.Content

           If Not IsNumeric(txtContentId.Text) Then
               lblResult.Text = "Invalid content ID"
               Exit Sub
           End If

       Dim contentItem As Ektron.Cms.ContentData

       Try
          contentItem = contentApi.GetContent(CInt(txtContentId.Text), Ektron.Cms.Content.EkContent.ContentResultType.Published)

          If (contentItem Is Nothing) Then
             lblResult.Text = "ContentBlock does not exist"
          Else
             lblResult.Text = contentItem.Title & "<br/>" & contentItem.Html
          End If
 

       Catch ex As Exception
           lblResult.Text = ex.Message
       End Try
 
   End Sub
