How to reload the default web-form page after clicked a Link button for a new tab

Use response.redirect with the url of current page.

use like any below

Response.Redirect("~/MyIntranet/Pages/Default.aspx", false) 
Response.Redirect("~/MyIntranet/Pages/Default.aspx", true) 
or

Response.Redirect("~/MyIntranet/Pages/Default.aspx")

Select allOpen in new window

somethimes problem may be due to lack of
lack of a "Handles Me.Load" clause in the Page_load subroutine declaration

codecruiser: I did, it still does work. Thanks.

AkilaPalanimuthu: I do have code  "Handles Me.Load" clause in the Page_load  sub declaration. Thanks

You mean it does NOT work? When a response.redirect is encountered, statements after that will be ignored. There is only one response and it can only be redirected to one url.

GalaGia,
Can you share some code?

For Link Button Control in the Main.aspx to open a new tab NewTab.aspx:

 <p class="MsoNormal" style="margin: 0in 0in 10pt">
            <span><span>
                                <asp:LinkButton ID="LinkButton1" runat="server" Height="18px" OnClientClick="form1.target ='_blank';"
                        PostBackUrl="~/NewTap.aspx" ToolTip="Click on this link" Width="148px" EnableViewState="False">View the notice</asp:LinkButton></span></span></span></span></p>


For Main.aspx and its Button control to open ThankYou.aspx in the same window:

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim FileNumber7 As Decimal = Request.QueryString("Val7")
    End Sub


  Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click


        Dim Username7 As String = Request.QueryString("Val7")
        'Dim FileNumber As Decimal = Request.QueryString("Val7")


        Dim DBconn As New SqlClient.SqlConnection("Data Source=;Initial Catalog=;Integrated Security=True;")
        Dim DBcmd As New SqlClient.SqlCommand
        Dim DBAdap As New SqlClient.SqlDataAdapter
        Dim DS As New DataSet

        DBconn.Open()
        Try
            DBcmd = New SqlClient.SqlCommand("update Temp_ set EnglishCheckbox =@eCheckbox, SpanishCheckbox=@sCheckbox, OtherLanguageCBox=@oCheckbox, languageName=@LanguageName,Signiture=@Signiture,SignitureDate = getdate() where [Number] =@FileNumber ", DBconn)
            DBcmd.Parameters.Add("@eCheckbox", SqlDbType.VarChar).Value = CheckBox1.Checked
            DBcmd.Parameters.Add("@sCheckbox", SqlDbType.VarChar).Value = CheckBox2.Checked
            ...........................
............................
.................................
            DBcmd.Parameters.Add("@FileNumber", SqlDbType.Float).Value = Request.QueryString("Val7")
            DBcmd.ExecuteNonQuery()
        Catch exp As Exception
            Response.Write(exp)
        End Try
        DBcmd.Dispose()
        DBconn.Close()
        DBconn = Nothing

        Response.Redirect("ThankYou.aspx?valfinal=" + Username7)

        ' End Sub
    End Sub

I placed the line inside of the subroutine of Button1_Click, it just didn't work:

Response.Redirect("~Main.aspx")

>Response.Redirect("ThankYou.aspx?valfinal=" + Username7)
>Response.Redirect("~Main.aspx")

Which page you actually want to redirect to?

guru_sami: it works now. Thanks a lot.

codeCruiser: in my page Main.aspx, there is a Botton control and a Link Button control. if click on the Link button, it should lead to a new tab NewTab.aspx, if click on the Button, it should open the Thankyou.aspx in the same window.
