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'm just new in ASP.Net.
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 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 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>}
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 have created user control and placed inside panel in main form. i made panel visible property false because i want to avoid user control html to load at form load time. The problem is that when i make panel visible true on checkbox selection user control is loading in main form but its html is not loading means when i check html code by source view its same as the form load time and because of this i am getting ajax problem as my calendar control is not working. If you know the solution of this
View 3 RepliesI have 3 columns in a GridView. The first is a templatefield with a button in it and then other 2 are just plain data from the database. Currently when I try to render the HTML from the GridView I see all 3 columns, but I only want to see the plain data fields. I have seen the answer as:gvQuotes.Columns[0].Visible = alse;But that doesn't work for me, because I still want to keep the first templatefield column on my page.
View 1 RepliesI have a web user control that actually takes a zipcode and based on that brings all the store locations. I am using this contol on couple of places. That works, but I have set of html pages and on one of them I have to setup the same functionality where user inputs zipcode and store locations are displayed to him/her.My question, Can I use that web user control as an applet on my html page without writing html markup and get post methods to achieve the same functionality?

Here is the contents of my test.ascx file:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="test.ascx.cs" Inherits="UserControls_test" %>
<p id="XXX">aaa</p>
and here is the contents of my test.ascx.cs file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class UserControls_test : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
this.XXX.InnerHtml = "BBB";
}
}
I get an error when I refer to the id, "XXX" (underlined above) in code behind which reads: 'UserControls_test' does not contain a definition for 'XXX' and no extension method 'XXX' accepting a first argument of type 'UserControls_test' could be found (are you missing a using directive or an assembly reference?)
I have tried XXX.InnerHtml and I have tried this.XXX.InnerHtml and get same problem.
How do I successfully refer to ID'ed HTML elements in code behind?
