Hello everyone
I just use a MsgBox component for ASP.NET using Methods such as Render and
OnPreRender and JavaScript involved to get a simple Confirmation Box in
client side, but the funny thing is when I go SmartNavigation property equal
True the MessageBox does not come up!
But if you open another window and return to the browser you can see the
pop-up window !!!
Any Suggestions?
This is the complete code to Confirmation Pop-up:
Imports System.ComponentModel
Imports System.Web.UI
Imports System.Web.UI.WebControls
Public Class MsgBox
Inherits System.Web.UI.WebControls.WebControl
Implements IPostBackEventHandler
Private _Message As String
Private _Key As String
Private _PostBackOnYes As Boolean
Private _PostBackOnNo As Boolean
Public Event YesChoosed(ByVal sender As Object, ByVal Key As String)
Public Event NoChoosed(ByVal sender As Object, ByVal Key As String)
Public Sub ShowConfirmation(ByVal Message As String, ByVal Key As
String, ByVal PostBackOnYes As Boolean, ByVal PostBackOnNo As Boolean)
_Message = "ÑaÑa" & Message
_Key = Key
_PostBackOnYes = PostBackOnYes
_PostBackOnNo = PostBackOnNo
End Sub
Public Sub ShowMessage(ByVal Message As String)
_Message = Message
End Sub
Protected Overrides Sub OnPreRender(ByVal e As EventArgs)
If Not MyBase.Page.IsClientScriptBlockRegistered("MsgBox" ) Then
Page.RegisterClientScriptBlock("MsgBox", FuncionJava1())
End Sub
Private Function FuncionJava1() As String
Dim miPostBackOnYes As String = "MsgBoxTextoMensaje="""";"
Dim miPostBackOnNo As String = "MsgBoxTextoMensaje="""";"
If _PostBackOnYes Then
miPostBackOnYes = Page.GetPostBackEventReference(Me, "Yes" & _Key)
End If
If _PostBackOnNo Then
miPostBackOnNo = Page.GetPostBackEventReference(Me, "No_" & _Key)
End If
Return "<script language=""javascript""> " & _
"var MsgBoxTipoMensaje; " & _
"var MsgBoxTextoMensaje; " & _
"window.attachEvent(""onfocus"", MsgBoxMostrarMensaje); " & _
"function MsgBoxMostrarMensaje() { " & _

"if (MsgBoxTextoMensaje != """") { " & _
"if (MsgBoxTipoMensaje==2) {" & _

"} else {" & _
"if (confirm(MsgBoxTextoMensaje)) { " & _
miPostBackOnYes & _
"} else { " & _
miPostBackOnNo & _
"}} MsgBoxTextoMensaje=""""; " & _
" }}} </script>"
End Function
<Security.Permissions.PermissionSetAttribute(Secur ity.Permissions.SecurityAction.Demand, Name:="FullTrust")> _
Protected Overrides Sub Render(ByVal writer As
System.Web.UI.HtmlTextWriter)
If ModoDisenio(Me) Then
writer.Write(Me.ID)
Else
If _Message <> String.Empty Then
Dim miSB As System.Text.StringBuilder = New
System.Text.StringBuilder(_Message)
miSB.Replace(Microsoft.VisualBasic.vbCr, " "c)
miSB.Replace(Microsoft.VisualBasic.vbLf, " "c)
miSB.Replace("""", "'"c)
If miSB.ToString.StartsWith("ÑaÑa") Then
Me.Page.Response.Write("<script>MsgBoxTipoMensaje= 1;
MsgBoxTextoMensaje=""" + _
miSB.ToString.Substring(4) + """;</script>")
Else
Me.Page.Response.Write("<script>MsgBoxTipoMensaje= 2;
MsgBoxTextoMensaje=""" + _
miSB.ToString + """;</script>")
End If
miSB = Nothing
End If
End If
End Sub
Private Shared Function ModoDisenio(ByVal QueControl As _
System.Web.UI.WebControls.WebControl) As Boolean
Dim DesignMode As Boolean = False
Try
DesignMode = QueControl.Site.DesignMode
Catch : End Try
Return DesignMode
End Function
Public Sub RaisePostBackEvent(ByVal eventArgument As String) _
Implements IPostBackEventHandler.RaisePostBackEvent
Select Case eventArgument.Substring(0, 3)
Case "Yes"
RaiseEvent YesChoosed(Me, eventArgument.Substring(3))
Case "No_"
RaiseEvent NoChoosed(Me, eventArgument.Substring(3))
End Select
End Sub
End Class
************************************************
You can save this code and generate a Component, after that I am using this
code:
MsgBox1.ShowConfirmation("Do you want to delete this record?", "BORRAR",
True, False)
AND if you click and SmartNavigation equal True the Windows will not comes up!
I realized that and some computers does not appear the window even if the
NavigationSmart is False !!!
Any Suggestions????

Hi Martz:
SmartNav causes all sorts of difficulties when JavaScript and DHTML
are involved on the page. The only good workaround is to get rid of
SmartNav.
If you need to persist scroll position, there are some techniques to
do that for 1.1 on the web.
