If it is possible to remove the message "This Page at Says" from the pop up page in Google Chrome.

Dim message As String

message = "alert('Kolom Propinsi belum dipilih !')"
ScriptManager.RegisterClientScriptBlock(TryCast(sender, Control), Me.GetType(), "alert", message, True)

Hey arie.keren,

You can't change the JavaScript alert box header name. But instead you can use JQuery dialog .

Please refer below sample.


<script type="text/javascript" src=""></script>
<script src="" type="text/javascript"></script>
<link href=""
    rel="stylesheet" type="text/css" />
<script type="text/javascript">
    function ShowPopup(message) {
        $(function () {
                title: "jQuery Dialog Popup",
                modal: true
<div id="dialog" style="display: none">



protected void Page_Load(object sender, EventArgs e)
    string message = "Kolom Propinsi belum dipilih !";
    ClientScript.RegisterStartupScript(this.GetType(), "Popup", "ShowPopup('" + message + "');", true);


Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    Dim message As String = "Kolom Propinsi belum dipilih !"
    ClientScript.RegisterStartupScript(Me.[GetType](), "Popup", "ShowPopup('" & message & "');", True)
End Sub
