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.

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 doing a rework on one of my sites and I am attempting to use the asp:menu control.
I am using images in the static and dynamic menus. Hard coded at this point.
On my local machine it works fine but when I upload to the server, the image on the dynamci menus do not appear.
Instead I just get white space where the images should be.
Here is the 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?

I have an image loaded in a div element. (This image will be added dynamically thru JS, based on the option selected by the user).
I have a requirement to open this image in Word, Excel and Pdf applications when those icons (given in the page) are clicked, respectively.
[Code]....
The same code works fine to render a gridview in excel, but not an image. I also tried placing the image element in a table tag.

I am new to web design so bear with me. I have an .aspx page with a user control at the top that is basically a container for an image. It serves as a banner spanning the entire page. The lower part of the page is a left and right sidebar with a main middle section.
The image is simply some text at the left layered over a background that fades from blue to white, top to bottom. Image size is 90 p. high by 1000 p. wide. How can I get this image to vary width withing the control along with the rest of the page when rendered under different screen resolutions?

I am developing a .Net Page that will contain a FileUpload box so a user can upload images to the site. I would like the functionality that when someone chooses a file to upload (before they actually upload the file), they can preview it on the browser. I know I can do this through some javascript magic, but is there anything that can be done using AJAX tools to gain this functionality.

I have a user control that's got an image ..when I added it to a page that doesn't have a Master Page..the image was getting displayed alright but when I added the same user control to a page with a Master Page.the image vanished!....When I checked the Page source the image's path was there like this. style = "background-image: [url] Image exists too! not that its gotten deleted or whatever.
Now idk where I read this but I did somewhere that when master page's added and user control's used..the ID s get changed or something..not sure..idk..if that's so..how on earth do IDs get changed and why and of what ? I just can't figure out what might have gone wrong..How do I test it?
[EDIT]
I checked the Page Source minutely again and guess what some div tag IDs have changed! ..I got this one div who's ID is "div1"..inside of this div is my Sprite image..now this "div1" is being changed to
...."ctl00_ContentPlaceHolder2_ctl00_Banner_ctl00_ContentPlaceHolder2_ctl00_Banner_div1"
Banner is variable of type UserControl declared in my test page(I am adding UserControl in code behind)...some more Div's IDs are being changed in a similar way...now what do I do about these changing IDs?

Imagine there's a web (mvc) application, which home directory on the server is the default c:intepubwwwroot. What i need is: user requests [URL] Server responses with a simple page with a random picture on it from a predefined path, which is not iis folder/app, like d:lolcats. This sample is tremendously simplified, of course. My solution is: when /randomPicture/ is requested, copy random picture to APP_Images/current_response.jpg or whatever to application home folder and then simply render <img src="../APP_Images/current_response.jpg" />

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.
