Create a text delimited string of content and display separated text in control on page.

Question

User1909155429 posted

I display a message on page using the code below. 

Dim msg As Message = CType(Session("Message"), Message)

FreeTextBox1.Text = Server.HtmlDecode(msg.Body)

What i want to do is display each bit of saved text in individual rows on page as read only content. While insert new text below content.

When saved the new text is added to the list of content and saved, ready to be displayed again in order of addition.

You can do this with repeater control-

    <form id="form1" runat="server">
        <asp:Repeater ID="rpt" runat="server">
            <ItemTemplate>
                <asp:TextBox runat="server"
                    Text="<%# Container.DataItem %>" ReadOnly="true"></asp:TextBox><br />
            </ItemTemplate>
        </asp:Repeater>
        <fieldset>
            New content:
            <asp:TextBox ID="txtNewData" runat="server"></asp:TextBox>
            <asp:Button ID="btnAddNew" runat="server" Text="Add new" OnClick="btnAddNew_Click" />
        </fieldset>
    </form>

Friend Class SurroundingClass
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        If Not Page.IsPostBack Then
            Session("Data") = "Text1|Text2|Text3" 'set initial data
            BindData()
        End If
    End Sub

    Private Sub BindData()
        rpt.DataSource = GetData()
        rpt.DataBind()
    End Sub

    Private Function GetData() As List(Of String)
        Return Session("Data").ToString().Split((New Char() {"|"c})).ToList()
    End Function

    Protected Sub btnAddNew_Click(ByVal sender As Object, ByVal e As EventArgs)
        Dim data = GetData()
        data.Add(txtNewData.Text)
        Session("Data") = String.Join("|", data)
        BindData()
    End Sub
End Class

That looks great. although i have aditional problem ,my saved string contains identity values

FreeTextBox1.Text = Server.HtmlDecode("Original Message<hr/> From: " & msg.SenderId &  msg.Body)

i would also like to delimiter the identity value and place above body text. so user knows who it is.

Thanks

Hi peterthegreat,

 

Have you solved the problem now? 

It looks like the additional problem is adding the identity values. However, it is not very clear.

Could you please specify what the problem is?

  

Thank you very much.

Best regards,

Sean
