[Solved] Multiline TextBox value in New line not working inside ASP.Net UpdatePanel

I have a multiline textbox.

When the user presses enter cursor moves to next line.

But when i save to database the txtmultiline.text does not show the next line and hence stored in a single line.

I google and could not find a good sample for my case.

Can you help me with a sample ?

txtmultiline.text does not show any escape string in next line.

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
        <asp:TextBox ID="TextBox1" TextMode="MultiLine" runat="server"></asp:TextBox><br />
        <asp:Label ID="Label1" runat="server" Text="Label"><br /></asp:Label>
        <br />
        <br />
        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
    </ContentTemplate>
</asp:UpdatePanel>

Public Class WebForm1
    Inherits System.Web.UI.Page 
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
    End Sub
 
    Protected Sub Button1_Click(sender As Object, e As EventArgs)
        Label1.Text = TextBox1.Text.Replace(Environment.NewLine, "<br/>")
    End Sub
End Class
