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 ?
In the below written code content is render vertically and in one coulmn only.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

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.

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 UserControl that has some javascript I'd like to inject into a known ContentPlaceHolder.
I was hoping to do something like the following except when I append to add the control to found control I get an exception which says I cannot modify the control collection in the Init, Load or PreRender events:
"UserControl.ascx"
[code]....
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?

how to display html content, image, hyperlink on textbox in reportviewer ?
I have a master page with a user control on it. How do I change the user control's properties from a content page?In my ascx file I created this 2 property:
[Code]....
In content page PageLoad event I wrote
[Code]....
On my master page , I have "Search textbox" and "Search Button".
On My content page , I have a "User Control" which has a "GridView".It shows some data about Vendors.
Also, on this User Control's Page Load, i have code written to display all vendors in GridView.
Now, when user enters Vendor Number in "Search textbox" , and hits "Search Button" , i want to handle this event inside my User Control.
How to do this ?
In ASP.NET MVC, how to get the page content before render, we know in Web form app, we can override the method
protected override void Render(HtmlTextWriter writer)
to get the page content before render. but in MVC there are no event concept, so how we can get the page content. the purpose for that is to emphasize(wrap <strong> tag) the keywords before the page rendered.
I'm using the ASP.NET 4.0 ASP.NET application. It comes wired up for menu, login, roles, etc. This question is about placing a user control (which just contains a label with Copyright info, always at the bottom of the page. It found the Site.css entry to make the border it puts around the content always the same size - so it's consistent on every page, but I've not found how to make the user control stick to the bottom of the page. Right now I use the "footer" class which auto centers the content in the user control, but nothing to make it appear at the bottom of the page, without putting a bunch of <br> tags (a different number of them for each page, to keep the user control at the bottom. I've currently putting the user control inside <div class="footer"> which picks up the centering from the Site.css.
View 1 RepliesI have a control that I want to be able to mark areas as editable. When a user enters a username and password, they can then edit these editable areas.One of the area to edit is the main content of the page. Since I want them to be able to edit this on every page, I have put the editable control into the master page, wrapped around the ContentPlaceHolder of the master page.I found out how to allow the parser to allow <prefix:tag></prefix:tag> rather than just ending it with />, but I can't figure out how to get the text within the tags to be accessible through something like a Text property. A prime example of this behavior is the Label control, where you can put <asp:Label>Hello!</asp:Label> and access Hello! through the .Text property in the code.

View 1 RepliesI 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.
Iam Creating a Hyperlink control in code behind user this way
string literalControl = "<asp:HyperLink ID="HyperLink1" onclick="fnClearField('asdf')" ForeColor="Red" Font-Underline=true CssClass="Row_Over_Ar_Ex" runat="server" >Clear</asp:HyperLink>";
cell.add( new literalcontrol(literalControl ))
but the control not showing all the style attributs, is this way the style attributes will not show?
do i have to create the server control using new hyperlink and then add all the attributes?
I have an application that needs to render a page that will have multiple Radio Button Groups as well as multiple CheckBoxes. The desired layout is determined by a database table.
table structure:
PackageID uniqueidentifier
PackageName string
ItemName string
RadioGroupName string
ViewControlName string
This table defines a "Package". The "Package" can contain many different "Items" that require different controls used in the View. The "RadioGroupName" field is used to mark which RadioButtons should be grouped together. The "ViewControl" field marks which control should be used on the View to display the field. The query in my repository will return a result set such as
1 / "First Package" / "Item1" / "First Group" / "RadioButton"
2 / "First Package" / "Item2" / "First Group" / "RadioButton"
3 / "First Package" / "Item3" / "First Group" / "RadioButton"
4 / "First Package" / "Item4" / null / "CheckBox"
5 / "First Package" / "Item5" / null / "CheckBox"
6 / "First Package" / "Item6" / "Second Group" / "RadioButton"
7 / "First Package" / "Item7" / "Second Group" / "RadioButton"
8 / "First Package" / "Item8" / "Second Group" / "RadioButton"
Given this result set, I need to render the view as follows:
A RadioButton group with 3 options (Item1, Item2, Item3)
A CheckBox (Item4)
A CheckBox (Item5)
A RadioButton group with 3 options (Item6, Item7, Item8)
I have read that it is possible to use "if" conditions and looping structures inside the View. I have also read that this is a bad practice. Another issue I see is knowing which Item has been selected from each RadioButton group when I hit the Controller POST function. Previously I have built a page that has a single RadioButton group. My ViewModel was as follows:
