ASP.NET 4 Hosting - ASPHostPortal :: ASP NET Custom Control with PersistenceMode.InnerProperty including Server Controls

clock January 17, 2011 06:22 by author Jervis

If we want to use a Custom Control with PersistenceMode.InnerProperty. And would like to include some Asp Server Controls we do following:

We create a aspx where the controls to be added:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default9.aspx.cs"
Inherits="Default9" %>

<%@ Register src="WebUserControl.ascx" tagname="WebUserControl" tagprefix="uc1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <uc1:WebUserControl ID="WebUserControl1" runat="server" >
        <FirstLevelInnerString>
            <asp:Literal ID="lita" Text="Halo" runat="server">
            </asp:Literal><br />
            <asp:LinkButton ID="vdsvs" Text="link" runat="server">
            </asp:LinkButton>
        </FirstLevelInnerString>
        <SecondLevelInnerString>Hallo vom</SecondLevelInnerString>
    </uc1:WebUserControl>
    <div>
    </div>
    </form>
</body>
</html>


After that create a usercontrol where yout put the following markup:

<%@ Control Language="C#" AutoEventWireup="true"
CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %>
<asp:PlaceHolder ID="Title" runat="server"></asp:PlaceHolder>
<asp:Literal id="litSecondLevelInnerString" runat="server"></asp:Literal>

Code:

[ParseChildren(true)]
public partial class WebUserControl : System.Web.UI.UserControl
{
    private ITemplate _title;

    [PersistenceMode(PersistenceMode.InnerProperty),
    TemplateContainer(typeof(TemplateControl))]
    public ITemplate FirstLevelInnerString
    {
        get { return _title; }
        set { _title = value; }
    }

    [PersistenceMode(PersistenceMode.InnerProperty)]
    public string SecondLevelInnerString
    {
        set
        {
            this.litSecondLevelInnerString.Text = value +
                " SecondLevelInnerString";
        }
    }

    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);
        if (_title != null)
        {
            _title.InstantiateIn(Title);
        }
    }
}

Thats it!

Now you can use Server Contols in PersistenceMode.InnerProperty Mode.

Solution:

Disable the ViewState on your static web controls like Labels. If the Label's value is not going to change on postback then it should have its viewstate disabled.

<asp:Label ID="mainmenu" runat="server" />


Should look like this

<asp:Label ID="mainmenu" runat="server" EnableViewState="false"/>

Of course this means you need to go through every page in your application and disable the viewstate on every control that requires it.

But if your page doesn't have any controls that need to have viewstate enabled you can just add the attribute to the page directive to disable the viewstate on all controls

So change this

<%@ Page  Language="C#"  %>

to this

<%@ Page  Language="C#" EnableViewState="False" %>

Hope it helps!!

ASP.NET 4 Hosting - ASPHostPortal :: HttpContext.Current and Threads with QueueUserWorkItem

clock January 12, 2011 05:44 by author Jervis

If you’ve got an ASP.NET (including MVC) application that uses ThreadPool.QueueUserWorkItem with a reset event or anything of the like, you can not access HttpContext.Current (or rather, it is null) on those threads. This makes exception logging difficult, especially if you want to log the URL that is currently being requested.

After a little digging, I discovered that the current HttpContext is actually in thread-local storage, which explains why child threads don’t have access to it. Luckily, you can pass a reference to it in your child thread. Include a reference to HttpContext in the “state” object of your callback method, and then you can store it to HttpContext.Current on that thread. If you notice, HttpContext.Current is not a read-only property – it has a setter as well. Set HttpContext.Current = myStateObj.HttpContextReference where myStateObj is your state object.

I feel like this post is a bit self-explanatory, but here’s an obligatory example if you don’t follow:

private AutoResetEvent s_reset = new AutoResetEvent(false);
protected void Page_Load(object sender, EventArgs e)
{
    var state = new WorkerState() { HttpContextReference = HttpContext.Current };
    ThreadPool.QueueUserWorkItem(new WaitCallback(Worker), state);
    Try
    {
        s_reset.WaitOne();
    }
    Finally
    {
        s_reset.Close();
    }
}
void Worker(object state)
{
    var mystate = state as WorkerState;
    if (mystate != null && mystate.HttpContextReference != null)
    {
        HttpContext.Current = mystate.HttpContextReference;
    }
    HttpContext.Current.Response.Write("Threading!");
    s_reset.Set();
}
private class WorkerState
{
    public HttpContext HttpContextReference { get; set; }
}

And, of course, it works:



Hope this helps!

ASP.NET 4 Hosting - ASPHostPortal :: Html Encoded Expressions in ASP.NET 4

clock January 10, 2011 07:28 by author Jervis

We all know <%=expression%> features in asp.net. We can print any string on page from there. Mostly we are using them in asp.net mvc. Now we have one new features with asp.net 4.0 that we have HTML Encoded Expressions and this prevent Cross scripting attack as we are html encoding them.

ASP.NET 4.0 introduces a new expression syntax
<%: expression %>
which automatically convert string into html encoded. Let’s take an example for that.

I have just created an hello word protected method which will return a simple string which contains characters that needed to be HTML Encoded. Below is code for that.

protected static string HelloWorld()


    return "Hello World!!! returns from function()!!!>>>>>>>>>>>>>>>>>";
}

Now let’s use the that hello world in our page html like below. I am going to use both expression to give you exact difference.

<form id="form1" runat="server">
<div>
    <strong><%: HelloWorld()%></strong>
</div>
<div>
    <strong><%= HelloWorld()%></strong>
</div>
</form>

Now let’s run the application and you can see in browser both look similar.



But when look into page source html in browser like below you can clearly see one is HTML Encoded and another one is not.



Happy Programming!!
