Web Form Render Engine Outputs A Control Tree / Looking For Info On Render Logic.

Feb 12, 2011

I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).

I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?

Multithreading - When Serve A Webpage -, Can Render The Various Controls On The Page In Parallel

Aug 10, 2010

When I serve an ASP.NET page, can I render the various controls on the page in parallel?

I have a few Telerik controls (RadGrids) on the page and when I step through the page being loaded, it seems as though the controls are databound and rendered serially.

Maybe this behavior is because I am hooked in with the debugger.

Is there anyway to load the page and have select controls build on separate threads? Is that even conceptually possible or must it be done sequentially?

Displaying Data Conditionally Within A User Control?

Feb 3, 2010

Within an ASP.NET user control I have the line:

<div>Web: <a href="<%# Eval("Web") %>"><%# Eval("Web") %></a></div>

I'd like to change it so this HTML is only rendered if Web has a value.

I've tried wrapping String.IsNullOrEmpty(Eval("Web") as string) in server side script but Eval can only be used inside a "binding" tag.

What is the best way to do this?

C# - Render Multiple Control Collections In Custom Control?

Mar 15, 2010

I've build a custom WebControl, which has the following structure:

<gws:ModalBox ID="ModalBox1" HeaderText="Title" runat="server">
<Contents>
<asp:Label ID="KeywordLabel" AssociatedControlID="KeywordTextBox" runat="server">Keyword: </asp:Label><br />
<asp:TextBox ID="KeywordTextBox" Text="" runat="server" />

[Code]....

However it seems to render properly, it doesn't work anymore if I add some asp.net labels and input controls inside the property (see above asp.net code). I'll get the HttpException:

Unable to find control with id 'KeywordTextBox' that is associated with the Label 'KeywordLabel'.

Somewhat understandable, because the label appears before the textbox in the controlcollection. However, with default asp.net controls it does work, so why doesn't this work? What am I doing wrong? Is it even possible to have two control collections in one control? Should I render it differently?

Web Forms :: Render A User Control As An Image?

Aug 2, 2010

I have a complicated user control on a form that's laid out they way the business unit wants it. What they would like is to be able to export this content to excel and/or PDF as an image. Basically I need to be able to render the user control as a static image.

Is there any simple way to do this or is it even possible? Since the user control is HTML, it's not really rendered at all at the server level as it's just HTML, so I would assume that I might need to interface with IE library.

Chart Control Too Slow Or Doesn't Render

Jan 20, 2010

I have a web page rendering two pie charts using the ASP.NET 3.5 chart controls. On my dev server (IIS 5.1) the charts load well. On the QA server, the charts load pretty slowly and sometimes one or both of them doesn't even load. I am loading the charts using the codebehind tag. Is there anything else that could be done to make these charts run faster? Note: I was previously using dotNETCHARTING and never had any issues with it. Nothing else has changed except for the charting engine.

Render Control To Html Produces A Different String?

Jul 7, 2010

I am trying to render a hyperlink to html. ( etc)

When the page loads it works fine. (and lots 10 links) on the update panel it hits the same function and tries to get another 10 links. I set the navigationURL to something like

"../Folder/Mypage.aspx?498592ghjgfosdfgo"

It is set identically both times(load and updatepanel postback) but when i try to render it to html the second time (on the update panel) it adds "../" to the front so i end up with

"../../Folder/Mypage.aspx?498592ghjgfosdfgo"

The function where it changes here

Public Shared Function RenderControl(ByVal c As Control) As String
Dim sw As New IO.StringWriter
Dim htmlw As New HtmlTextWriter(sw)
c.RenderControl(htmlw)
Return sw.ToString
End Function

c is the hyperlink which has the propertry navigationurl (this never gets changed) but the sw which ends up looking like this on load

<a id="lnkView" href="../Folder/mypage.aspx?AnTfh0ZsFP9NCxiBpM+Zd11cI+AUOF93HZQtumPgzMKky0PejGrda9I6kCFn070dOsIfq0M2AgI=">View</a>}

and this on panel update

<a id="lnkView" href="../../Folder/mypage.aspx?AnTfh0ZsFP9NCxiBpM+Zd11cI+AUOF93HZQtumPgzMKky0PejGrda9I6kCFn070dOsIfq0M2AgI=">View</a>}

Security Exception When Trying To Render A ReCaptcha Control

Oct 29, 2010

I've downloaded the recaptcha.dll in both 1.0.1.0 and 1.0.4.0. When trying to render the control, I get the following exception: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

The solution to this, as provided by a quick Googling, is to use caspol.exe to add full trust to the recaptcha.dll assembly. C:\%path%caspol -af C:inetpubwwwroot\%path%in ecaptcha.dll At this point, I get the following error: ERROR: This assembly is not strong name signed Short of downloading the source code and recompiling it locally, is there any other way to get this working?

Web Forms :: How To Render Control Dynamically Based On Configuration

Mar 25, 2010

I have come across a requirement to dynamically show or hide asp.net web controls , html server controls. I want to do this through a configuration XML (as it would be easier to config). So each page /aspx will have a configuration xml.

Would it be possible to create a control (may be a custom control , to which i can attach the xml file). The control (lets says - call it sequencer) should decide which control should be ordered in which order and if the control has to be shown or not. Ideally this sequencer control should use the page events and take decision on rendering the child controls.

Some thing like this

aspx -

<Sequencer XmlPath=".." Id="S1" Runat="server">
<Textbox id="t1" runat="server" />
<Textbox id="t2" runat="server" />
<Textbox id="t3" runat="server" />
</Sequencer>

This is hiw xml config may look like -

<Sequencer Id="S1">
<control id="t1" sequence="2" show="true" />
<control id="t2" sequence="1" show="true" />
<control id="t3" sequence="3" show="false" />
</Sequencer>

So in this case t2 should be rendered first then t1. The control id in the xml and the aspx has to be same.

t3 should not be rendered at all on the screen.

Which page load event should I use.

how I can create this kind of a custom control that does the above for me.

C# - How To Render User Control Children At A Specific Location

Jan 7, 2010

I have a very simplistic user control that looks like this:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="wfWindow.ascx.cs" Inherits="webfanatix.co.za.wfWindow" %>
<div>Just a test...[x]</div>

with this code behind:

[ParseChildren(false)]
[PersistChildren(true)]
public partial class wfWindow : System.Web.UI.UserControl
{
protected override void Render(HtmlTextWriter writer)
{
RenderChildren(writer);
}
}

And the usage thereof looks like this:

<wf:wfWindow runat="server">This content should go where [x] is.</wf:wfWindow>

I'm no ASP.NET pro, so how do I get the content to render exactly where the [x] appears in my user control?

RenderChildren is rendering my content, but it is only appended to the end of the UserControl output. I need it to go and sit right where [x] marks the spot.

public class Menu : WebControl
{

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</Template>
</MdsMenu:MenuItem>
</MdsMenu:MenuItem>
</MdsMenu:MenuItem>
</MdsMenu:Menu>

Now, How can I Parse it and render it in RenderContent method ? !!!
The following method is always throw the first Exception, it means this.Controls is always empty !!! How can I do it and how I can access to the nested children in RenderControl method ?

public class Menu : WebControl
{
....
public override void RenderControl(HtmlTextWriter output)
{
if (!this.HasControls())
throw new Exception("Controls are empty");
....
}
}
