I want to render a Web User Control (has many server controls inside of it) as a HTML string, is there anyway to do it?
I am using web user control and making it visible false initially (page load) and on the selection of checkbox i am making it visible true. user control html is missing when i load it on checkbox selection. is there any when that i rebind the complete form again on checkbox selection so that user control html should be rendered.
i am really struggling to solve this issue since last two days.
Render User Control with Events in html
View 6 RepliesI 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>}
Iam getting the below string in a variable"result" after xslt tranformation. if i do Page.ParseControl(result) iam able to render controls to the page. But the requirement is different. I have 4 place holders in that aspx page.I need to bind div id="Section1" to placeholder1, div id="Section2" to placeholder2 and similar the other two sections also to the corresponding place holder. how can i loop and add controls to corresponding place holder.

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.
I want to render a user control in pagemethod and return the html back to client. But its getting annoying, I tried like many ways but nothing found working. The problem is that, the usercontrol require both HtmlHead and ScriptManager.
I tried this but it doesn't work(raise error : ScriptManger require in page) because ScriptManager must be inside HtmlForm but Page.Form always null.
[Code]....
I have a scenario where, the content is:
[code]....
The entire div code is rendered and is sent at a mail using the code:
[Code]....
This works fine except that the User Control does not get rendered.
so that the User Control content is also rendered ?
I m new in mvc architecture and i want to bind data in html render control using Dataset .
View 2 RepliesI've these codes in my DATABASE in other words it's HTML. I tried these stuff:
<div runat="server" id="div1" visible="false">
<asp:Literal ID="literal1" runat="server" Text="" />
</div>
I tried in C# code behind:
div1.InnerText = contents;
div1.InnerHtml = contents
literal1.Text = contents;
But is still doesn't render well. I displays the original values in stead of a table and cells and columns. colours etc. etc....
What am I missing?
All these HTML's are in DABASE.Column e.g. column "Contents"
e.g.
"& lt;p class=& quot;MsoNormal" style= "color: #339966;"><"
;" ;> ;< ;strong > ;&l
ot; > ;& ;nbsp; < ;/span >< ;/p >
I've put (spaces between & and gt above code otherwise it was not showing in stackoverflow.) The HTML sysntaxs are correct because it's created by an HTMLEDITOR.
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.
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?

I have an application that renders HTML code to allow users to preview an email that the app sends out. The HTML is held in a string that is then put into the text property of a label. This is working fine, but now I need to also add XML to the HTML string for an email listener when the user clicks the Send button. The problem is that the XML tags are being ignored by the browser.
Here's the HTML string with the XML (at bottom):
MyHTMLString = @"
<HTML>
<head>
...
</head>
<Body>
...
<SomeXMLTag>TagContent</SomeXMLTag>
</Body>"
This string is then assigned to a label for previewing:
lblPreview.Text = MyHTMLString
But only "TagContent" appears and not the XML tags! Obviously, the HTML is ignoring tags it doesn't understand. How can I get the tags to also appear?
I am writing a content management system using JQuery.ajax & C#. The JQuery calls an httpHandler and POSTS the html from an html editor JQuery plugin.
I get an error in the handler about unsafe content (html basically) but I dont want turn off validation for the whole page, just the handler (the handler is part of a web control not the page).
So, is it possible to turn the validation off just for one handler? Or do I need to encode the html on the client?
In the end I went for the encoding on the client at Javascript/JQuery HTML Encoding
