I need help in prompting a window msg box in asp.net
PromptCreateItem.aspx is a webform.

Private Sub promptmsgbox(ByVal TargetPage As Page)
Dim strScript As String = "<script language=javascript>window.open('PromptCreateItem. aspx?" & "&url=Drinks.aspx"" ','cal','width=220,height=210,left=270,top=180')</script>"
TargetPage.RegisterClientScriptBlock("promptmsgbox ", strScript)

End Sub

When i click on create button, it wil check whether the inserting of record has been sucessful.
If it is sucessful it will ask the user whether he want to create another new item.
If checkstatus = True Then
            promptmsgbox(Page)
End If

I having problem how to response.redirect to the parent page to create the item rather then response redirect the link in the pop up window? KitchenMain.aspx has frame how to target the link to the content frame?

// If user click Yes in the pop up window
Private Sub btnYes_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnYes.Click
        Dim url As String
        url = Request.QueryString("url")
        Response.Redirect(url)
End Sub

// If user click No in the pop up window
Private Sub btnNo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNo.Click
        Response.Redirect("KitchenMain.aspx")
    End Sub
:D

I'm not 100% sure of what you are asking. Are you saying that based on a button pressed in the popup window, you want to redirect the main window (parent or opener) to a different URL?

If this is the case, then instead of using Response.Redirect, you need to send back some javascript to the popup window page that tells the parent window where to go:

opener.location.href="....";

This will tell the popup window's opener object (the parent window) what location to go to.
