Remove tab and new line space using RegularExpression in ASP.Net

Dear All,

I am trying to implement Google Map using Repeater and SQL Database based on the article: https://www.aspsnippets.com/Articles/ASPNet-Google-Maps-V3-with-Multiple-Markers-Database-Example.aspx

The Google Map is not displaying on web, unless I "cut and paste" the Description text directly from SQL database.

Here is the code:

<div id="dvMap" style="border: thin solid #87ceeb; width:100%; height:300px;"></div>

<script type="text/javascript">
    var markers = [
    <asp:Repeater ID="rptMarkers" runat="server">
    <ItemTemplate>
                {
                    "lat": '<%# Eval("PersonBruddLATITUDE") %>',
                    "lng": '<%# Eval("PersonBruddLONGITUDE") %>',
                    "title": '<%# Eval("PersonShipName") %>',
                    "description": '<%# Eval("PersonBruddDescription") %>'
                }
</ItemTemplate>
<SeparatorTemplate>
    ,
</SeparatorTemplate>
</asp:Repeater>
    ];

</script>

<script type="text/javascript">

    window.onload = function () {

        var mapOptions = {
            center: new google.maps.LatLng(markers[0].lat, markers[0].lng),
            zoom: 10,
            gestureHandling: 'greedy',
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };

        var icon = "http://www.kystregister.no/assets/img/locationSea.png";

        var infoWindow = new google.maps.InfoWindow();

        var map = new google.maps.Map(document.getElementById("dvMap"), mapOptions);

        for (i = 0; i < markers.length; i++) {

            var data = markers[i];

            var myLatlng = new google.maps.LatLng(data.lat, data.lng);

            var marker = new google.maps.Marker({ position: myLatlng, draggable: false, map: map, animation: google.maps.Animation.DROP, icon: new google.maps.MarkerImage(icon) });

            (function (marker, data) {

                google.maps.event.addListener(marker, "click", function () {

                    infoWindow.setContent("<div style = 'color:#12969b; font-weight:bold;'>" + data.title  + "</div>" + "<br>" + "<div style = 'color:#2d2625;'>" + data.description + "</div>" + "<br>");
                    infoWindow.open(map, marker);
                });
            })(marker, data);
        }
    }
</script>

Code behind:

            if (!this.IsPostBack)
            {
                DataTable dt = GetData("select * from brudd_Los where catID ='" + dataID.Text.Trim() + "'");
                rptMarkers.DataSource = dt;
                rptMarkers.DataBind();
            }

<asp:TextBox ID="dataID" runat="server" > </asp:TextBox> 
<asp:Button ID="Ebutton" runat="server" onclick="Button1_Click" />

How to solve this issue?

Many thanks
