How to use "History" in Master Pager & Detail Pager ?

lifereader — Tue, 16 Jun 2009 10:27:37 GMT

Hi,

EveryBody knows when use AJAX UpdatePanel with GridView, you change the gridview page and redirect to another web page, and then click preview button in browser, the gridview's pageindex will be the first page.

The solution is import Microsoft.Web.Preview.dll and add a "History" controler in the *.aspx page, but my problem is ... my project using Master Page and has a lot of detail pager, they will point to the same master page like MasterPageFile="~/main.Master"

Now I am trying to add History in my page, but it's seems didn't work.

How do I make it work & Where do I add this controler ?

1    <%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %>

How to work with SessionNavigationHistory?

kak.mca — Fri, 03 Oct 2008 08:04:27 GMT

Hi,

Good morning to every one.

Can anyone please tell how to work with SessionNavigationHistory.
I couldn't understand how to import the namespace

I have seen in one article like this:
Dim str As BaseClasses.Web.SessionNavigationHistory = Me.GetSessionNavigationHistory
Dim stry As BaseClasses.Web.SessionNavigationHistory.RequestInfo = str.GetPreviousRequest()

Do we need to import any .dll to use BaseClasses.Web namespace?

How can I work with this?

Thanks,

ExportWebPart javascript bug in ASP.NET AJAX Futures 2007

smasher9 — Mon, 12 Jan 2009 03:41:53 GMT

Hi,

I use ASP.NET AJAX Futures 2007 for Drag Drop support in FireFox. But in IE the Export web part feature stops working now.

I found that, the WebPartManager javascript object in ASP.NET AJAX Futures JS library doesn't have the ExportWebPart method which is called to export web part. (The original ASP.Net WebPartManager javascript object has this method).

Is there any solution for this problem? Will it be fixed in the next version of ASP.NET AJAX Futures?

Thanks.

XAP or ASPX or Mixuture?

Rimbik — Tue, 24 Mar 2009 06:58:49 GMT

Silverlight or ASPX ?

I am using Silverlight since last 25 days and it changed the way of coding. I am embedding everything in xap which makes me little confuse.

My Question:

1. To what extend we need to write the code in aspx

2. If I am developing and ASP.NET application with Silverlight what proportion of code normally I need to put in XAML considering all pages are fully powered by Silverlight pages.

Basically to be more clear: Say for example u have gotta a requirement to develop an ASP.NET application with all Silverlight pages what you will do.

Requirement:

1. Any kind of State Management may be used in the Web App should be robust enough to modify/migrate (Agile)

2. The application can have any basic ASP.NET features

That is before I start designing the application. How will I go like what to put in xap and what in aspx?

I am expecting an expert advice in this regard.

BUG?!: History.AddHistoryPoint(Dictionary state) does not work.

Noffie — Thu, 31 May 2007 16:06:57 GMT

I've noticed that trying to use History.AddHistoryPoint(Dictionary<string, object> state) in the History control class from the May 2007 Futures does NOT work. Everything compiles and runs, and I can see that the method is being called by stepping through my code, but no "Back" entries are added in the browser, and hitting back does not work as expected.

Using History.AddHistoryPoint(string key, object state) DOES work as expected (and that is the only method that is used in the ASP.NET Quickstart examples). I looked at both methods in .NET Reflector and my theory is that History.AddHistoryPoint(Dictionary<string, object> state) is missing a "this._newPointCreated = true; " that is present in the other overloaded version of the method.

Here is the code for each in my assembly:

public void AddHistoryPoint(Dictionary<string, object> state)
{
    if (this._initialState == null)
    {
        this._initialState = new Dictionary<string, object>();
    }
    foreach (KeyValuePair<string, object> pair in state)
    {
        if (pair.Value == null)
        {
            if (this._initialState.ContainsKey(pair.Key))
            {
                this._initialState.Remove(pair.Key);
            }
            continue;
        }
        if (this._initialState.ContainsKey(pair.Key))
        {
            this._initialState[pair.Key] = pair.Value;
            continue;
        }
        this._initialState.Add(pair.Key, pair.Value);
    }
}

public void AddHistoryPoint(string key, object state)
{
    this._newPointCreated = true;
    if (this._initialState == null)
    {
        this._initialState = new Dictionary<string, object>(1);
    }
    if (state == null)
    {
        if (this._initialState.ContainsKey(key))
        {
            this._initialState.Remove(key);
        }
    }
    else if (this._initialState.ContainsKey(key))
    {
        this._initialState[key] = state;
    }
    else
    {
        this._initialState.Add(key, state);
    }
}

Is this a bug, or am I just missing something?  Here is how I made my call to  History.AddHistoryPoint(Dictionary<string, object> state): 
     private void MarkHistory()
    {
        System.Collections.Generic.Dictionary<string,object> state =
            new System.Collections.Generic.Dictionary<string,object>();

        state.Add("viewingAll", ViewAllUsers);
        state.Add("currentPage", pagerUsers.PagerIndex);
        histUserList.AddHistoryPoint(state);
    }

ASP.NET Futures: WebPartManager and WebPartZone

ajd — Fri, 06 Feb 2009 01:01:11 GMT

Hi,

I have read the post on this page

http://waitink.blogspot.com/2008/06/ajax-web-parts-part-1-drag-and-drop.html

and am confused about where to obtain the WebPartManager and WebPartZone controls that were previously part of ASP.NET Futures, and mentioned in the above blog in the "Web Part Drag and Drop in Firefox" section.

The post says to download the ASP.NET futures from

http://www.asp.net/Downloads/futures/

It seems as though ASP.NET Futures no longer exists and a new codeplex page now exists at

http://www.codeplex.com/aspnet

Does anybody know where to obtain these controls that were previously part of the Futures release?

I am trying to get drag and drop of web parts working in Firefox.

Thanks.

Drag and Drop

aspwhiz — Fri, 06 Feb 2009 20:13:17 GMT

What is the current state of drag and drop? Is Microsoft continuing with this? I'm still using VS 2005 but don't want to use the version that has d&d unless I know that it is still an included feature in the new releases.

Thanks

ClientID is WOW! in ASP.NET 4.0

Ivannicoff — Sun, 18 Jan 2009 16:33:20 GMT

ClientIDs in ASP.NET is the most usefull implementation but what else will be in Future Web Forms.

As I understood from channel's 9 information are:

CSS rendering mode - but no comments.

Routing - no comments.

Also no sugeestion lists, no forums answers.

So can anybody comment new CSS rendering mode, does anybody know are new controls planned?

Video does not appear

Nicoxx — Mon, 29 Dec 2008 19:01:16 GMT

Hi all.. i want to have a video in a page... so i follow the steps that are in bloggs but doesnt work...

Im working with Visual Studio 2005 (in visual basic), i installed ASP AJAX Extension 1... and then installed ASP.Net Futures.

The code that i have is this:

<asp:ScriptManager ID="ScriptManager1" runat="server" />
  <asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
      <cc1:Media ID="Media1" runat="server" Height="240px" MediaUrl="~/thevideo.wmv" Width="320px">
      </cc1:Media>
    </ContentTemplate>
  </asp:UpdatePanel>

When i "Drag and Drop" the media from the toolbox it appears correct in the design view... i add the url of the video that is in the same folder of the proyect.. but when i run the proyect... it in the place that the video must be... there is nothing. At the begining of the page is the code:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="index.aspx.vb" Inherits="_Default" %>

<%@ Register Assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
    Namespace="System.Web.UI" TagPrefix="asp" %>

<%@ Register Assembly="Microsoft.Web.Preview" Namespace="Microsoft.Web.Preview.UI.Controls"
    TagPrefix="cc1" %>

Anyone knows whats the problem??? thanks for any help :)

form data

wsyeager — Tue, 27 May 2008 19:14:13 GMT

I'm using IE7 & Firefox 2.0 for my test.

I have 3 text boxes on Page1 which I type in some data for. I then pass this data to Page2 via a querystring value as follows in my Button click event.

<code>

Response.Redirect("page3.aspx?Text1=" & TextBox1.Text & "&Text2=" & TextBox2.Text & "&Text3=" & TextBox3.Text)

</code>

When redirecting (Response.Redirect) from Page1 to Page2, Page 2 populates the querystring values into some textboxes (existing on Page2).

When I press the Firefox "BACK" button (fromPage2 to Page1), the form data is preserved on Page1. If I do the same thing for IE7, the form data is gone on Page1 (meaning not preserved)!

I have the following HTML for this simple AJAX futures website which executes in both browsers:

<code>

</code>

If I remove the ScriptManager and UpdatePanel, the form data in IE7 is preserved when I go back to Page1.

How come when using the above HTML, the form data is preserved in FireFox, but not in IE when using AJAX?

Multi Dimension HTML table

Where did Sys.Preview.UI.HyperLink go?

martijnvm — Fri, 12 Dec 2008 13:46:07 GMT

I ran in to a problem while upgrading my webapp from Framework 2.0 to Framework 3.5 SP1. In my app I had a custom client control which derives from Sys.Preview.UI.HyperLink. I had to add a reference to Microsoft.Web.Preview.dll to make it work. I thought that this dll was Framework 2.0 specific.

But after upgrading to the 3.5 Framework and removing the dll and the reference to it, it can´t find the Sys.Preview.UI.HyperLink class.

What am I doing wrong?

Web Parts - AJAX not allowing to drop

jzickgraf — Thu, 04 Oct 2007 15:54:06 GMT

I'm using VS Beta 2 with ASP.NET Futures and am targeting the 3.5 framework.

I created 2 simple test pages to test the Drag and Drop features for Web Parts for IE, Firefox, and Opera. The first is a NonAJAX version the second has a script manager and update panels to prevent the whole page from posting back.

There are 2 WebPartZones. Each has a Textbox in the zone and there is a button to turn on design mode. The NonAjax version works great and the drag and drop works fine. However, the AJAX version won't allow me to drop the webpart from one zone into another zone for IE and won't allow me to drag for Firefox or Opera.

Any ideas? Below is the aspx code. Button1_Click toggles the mode from Browse to Design

— Fri, 07 Nov 2008 21:51:23 GMT

Hi, I have been playing around with the Sample Site that comes with the Futures release. I noticed that there is the ability to generate a UI from a simple object, but I have not seen an easy way to modify this and generate a hierarchical UI (TreeView) from a complex nested object. Are there any plans to add this? Or does anyone have any guidance on the best way for me to do this myself? Or am I barking up the wrong tree by attempting to use the dynamic data framework for this?

Could not load file or assembly 'System.Web.Extensions, Version=3.5.0.0 (and etc.) HRESULT 0x8013104

v2gusk — Fri, 10 Aug 2007 21:45:01 GMT

That little HRESULT, as you may know, means exactly what the error says: The assembly wasn't found.

I have a Visual Studio 2005 web project I'm publishing into a folder. When I copy that folder up to it's location on my test server, I get the following message because .NET Framework 3.5 is not installed on that server (nor should it have to be--the AJAX extension DLL is already on that server).

I looked though all my Project settings, to see if I was missing something that was telling VS to reference System.Web.Extensions as a .NET 3.5 (instead of an ASP.NET AJAX 1.0) assembly, to no avail.

This is what the assembly reference is in the web.config, so I would have thought it would also output for the precompiled site:
'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

And this is what ends up causing the error:
'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

Does anyone know how VS 2005 can automatically decide to change my references at compile-time? Is there a way for me to override that behavior? And shouldn't it be a default behavior to do exactly as the user asks?

Uninstalling Framework 3.5 (Pre-release)--and then re-doing the publish--resolved the issue, but now VS 2008 Beta 2 doesn't have .NET 3.5 to build off of.

I really want this to be a pre-release glitch, so let me know if you need more information to solve this.

Dynamic Controls displayes wrong table!!!

rfurdzik — Thu, 03 Jan 2008 00:32:08 GMT

I have two tables rm_feautres(feature_id, description) and rm_UserViewedFeature (user_id, feature_id). Now when I go to http://localhost/IwantIoffer/Admin/rm_feature.aspx, it display content of rm_UserViewedFeature table!!! This seems like some bug!

For some reason it displayes the wrong table. Here is my web.config entry:

<!--

By default, Dynamic Data Controls use the name of the table as the folder name. This

can be overridden by using a mapping here.

Sample mappings:

-->

</nameMap>

</dynamicDataControls>

Here is my rm_feature.aspx page:

<%@ Page Language="C#" CodeFile="rm_feature.aspx.cs" Inherits="Admin_rm_features"

MasterPageFile="~/MasterPage_new.master" Title="Manage Features"%>

<asp:Content ID="MainContent" ContentPlaceHolderID="Main" runat="server" >

browser history do not work properly

hublubble — Tue, 01 Apr 2008 14:11:33 GMT

Hi,

I have an ajax enabled asp.net 2.0 page. There are some updatepanels on it and I use the history control to enable the browser history buttons. For first time the AddHistoryPoint method adds a history point to my history control. That works, I think. But on Navigate event, the args.State will contain no key! There is no entry in the dictionary! Therefore my navigation function breaks. Has anybody some similar effect? Or better a solution!

Thnxs.
