How To Retrieve HTML Dynamically Generated From An Page
Jul 28, 2010
I'm coding an ASP.NET page, with VB code behind. When the user clicks a button on the page, I send them an email with information and instructions. Rather than sending a plain text email, I send a nice, pretty, HTML-formatted one. Right now, I'm doing this in a way that I KNOW will be difficult to maintain. That is, I'm straight up writing out all of the html. i.e.
markup += "<fieldset>"
markup += "<legend>"
markup += "Required Documents"
markup += "</legend>"
and so on. Is there a way to create an aspx page (with vb code behind), and send the html of that page in the body of the email? The information is dynamic, so this pseudo-page would need logic in the on-load event to format the html correctly.

I have this gridview made.But it gets populated with columns, column names and template fields dynamically. The template field tht I am using throught the field in each colum is a textbox. The user when loads this page sees a gridview with texboxes in all the columns. I need to be able to retrieve the data entered by the user in the textboxes on a button click.
public class GridViewTemplate : ITemplate
{
private DataControlRowType templateType;
private string columnName;
public GridViewTemplate(DataControlRowType type, string colName)
{
templateType = type;
columnName = colName;
public void InstantiateIn(System.Web.UI.Control container)
{
switch (templateType)

I have an ASP.NET web forms site with a rather large menu. The HTML for the menu is dynamically generated via a method in the C# as a string. I.e., what is being returned is something like this:
<ul><li><a href='default.aspx?param=1&anotherparam=2'>LINK</a></li></ul>
Except it is a lot bigger, and the lists are nested up to 4 deep.
This is written to the page via a code block.
However, instead of returning a flat string from the method I would like to return it as formatted HTML, so when rendered it looks like this:
<ul>
<li>
<a href='default.aspx?param=1&anotherparam=2'>LINK</a>
</li>
</ul>
I thought about loading the html into an XmlDocument but it doesn't like the & character found in the query strings.

I have an asp.net page where i have the below markup.Basically this markup is generated from codebehind by reading records from a table and looping thru them.For each record in table,there will be a div block. Basically this form is to read/show settings for a user.The settings entries are stored in a table.
<div id='divContainer' runat='server'>
<div id='div1' runat='server'>
<table>
<tr>
<th>Name</th>
<td><input type='text' id='txtName1' value='something' /></td>
</tr>
</table>
</div>
<div id='div2' runat='server'>
<table>
<tr>
<th>Domain name</th>
<td><input type='text' id='txtName2' value='something' /></td>
</tr>
</table>
</div>
<div id='div3' runat='server'>
<table>
<tr>
<th>URL</th>
<td><input type='text' id='txtName3' value='something' /></td>
</tr>
</table>
</div>
<div id='div4' runat='server'>
<table>
<tr>
<th>Some other value is enabled ?</th>
<td><input type='checkbox' id='chk4' /></td>
</tr>
</table>
</div>
</div>
The id's of each input element will be unique. Now in codebehind i want to read the values of each input elment to save the changes user made.How can i read the elements here ? Since the mark up is generated in codebehind as a string and appended the the INNER HTML of the external div,I cant read values like we do for a control which we drag and drop in the IDE.

I am currently generating a .doc file as html using asp.NET.
I wish to insert a page break to the page but don't know how.
I've tried using the css style='page-break-before:always' but it does nothing.
This is the code assigned to a button click event:
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Charset ="";
HttpContext.Current.Response.ContentType ="application/msword";
string strFileName = "GenerateDocument"+ ".doc";

I developed a basic web page in MVC 2 for learning the framework, and I am stuck in this situation:
I have 3 classes: Client - Product - New. And for all need to display a modal popup to create/edit action. For display the modal i used JQuery and jqModal plug-in.
I created the controllers for all objects, the views for Index action, and Delete action. For the Create/Edit Action I created a partial view named ModalBox. Inside this partial view, I have an Ajax.BeginForm, and it calls another partial, that represent the form of the objects.
This works very fine, ... for the project object! in FireFox 3.6, for others object's the form tag is missing...

I would like to send an Html email. The body for this email I would like to create completely dynamically. How do I create an html page completely from scratch so that I then have a page that I can add controls to? Do I create an instance of the System.Web.UI.Page class, add my controls to it and then render it as a string that I can assign to the message body?

I have a series of div where the id is tagged with the conventional:
<div id="result<%=order.ID %>">
The handler that submits the form can find out what order.ID is via:
fromInput.split(",")[1]
So how do i get that element concatenated with the static part of the DIV id?

I have a dropdownlist on my page which has autopostback set to true. On postback I populate a runat server div with a bunch of other DropDownLists. I then have a button which does another postback to save the selections. Because the second set of dropdownlists are dynamically generated I cannot for the life of me figure out how to get their selected values?
1st DropDownList
[Code]....
Then when I try get the dropdownlists using a foreach on the div that I added the control to it does not work. They are populating fine, its just on the button click. I have tried EnableViewState = true on the dropdownlists and my code is correct because if I code them into the aspx then it works, its something to do with the state.

I'm displaying a table based on query results, and each record has a dynamically generated dropdownlist and submit button (and other controls, but this is simplified). That part works fine, but how do I reference the controls in a function? Here is the code I've tried. Create the controls:
[Code]....
Reference the control values (hopefully):
[Code]....
The function SubmitAction_Click fires when I click the Post button, so that part works. I just can't figure out how to reference the selected value of the dropdownlist. You can see that I'm explicitly giving the DDL a unique ID (DS_RecordID). I'm guessing I have to use FindControl to reference it, but I don't know how to format the code.

I have implemented a user control with dropdown lists and textboxes where user may choose to add more of the same user control dynamically then submit the values within all usercontrols at the same time. They way I added usercontrols dynamically is whenever user clicks "add more" button, it increases the value of "userControlAmount" in session by 1, reloads the page and during next page_load event, within an updatepanel it creates usercontrols on the fly.
However whenever more is added since all usercontrols are generated again according to the latest user control counter, the values within the dropdownlists and textboxes are getting reseted.
I can hold all values in a viewstate/session however beyond the time/effort it will take, it doesn't sounds very "professional" to me. I was wondering if there is a more efficient way of doing this.

Is there a way to use a generated file as a configSource for a web.config section?
In web.config, I tried a simple:
<webParts configSource="webpartsConfig.aspx" />
where webpartsConfig.aspx just spits out XML when accessed normally, but not as a configSource. (The literal source code is included as-is, giving an error.)
Motivation for this solution: I have different configuration variables locally and online, and I don't want to juggle multiple config files.

so I have drop down list connected to a datasource, and I need to change 2 or 3 of the values before they are displayed and I'm just having trouble figuring out what to do. I'm assuming I setup some kind of loop to check the values, but thats all I can figure.

My goal is to take some form inputs and prompt the user to download a summary of everything once a certain button is clicked. I have no need for the file once it is downloaded and so I'd like to have a solution where the data is streamed directly to the user. My current solution doesn't even prompt the user for a download. Can anyone point out what I'm doing wrong?
I've got it wrapped as a webmethod and so I needed to add a definition of the _Default page class so I could access certain things.
[Code]....
this wasn't mentioned earlier but the webmethod is being called by an AJAX request!

I have a form that has dynamically generated textboxes using javascript.
My question is how can I read the values of these dynamically generated textboxes since I dont see any HTML in the page source for these textboxes even though they appear in the page.
I tried to read using
var str = document.getElementById('txtHello').value;
It always returns null.
txtHello is the Id which I have given to the textbox when I generated it dynamically using javascript.

I've to implement dynamically generated 'Tests'. It seems the best asp control to handle each's test option is the RadioButtomList control, thus I am writting in c# code to load programatically a table, render on rows the Tests' questions, and the options via radiobtuttonlist as the code bellow shows.
THE PROBLEM's since I did not ID each radiobuttomlist, once the test's end user submit his choices, I do not know how to get the selected item for each control so I can compute the results.

Let's say I have a booking form which is divided into 3 separate views in a multi view.
View 1: "How many people do you want to book for?" And then just a text box
View 2: "Please enter the details for each of the people" And then a series of dynamically generated text boxes - the number of boxes is determined by the value in the textbox in view 1 (e.g. if the users enters "3" into the text box, there will be 3 series of text boxes like "Details of person 1: First Name <textbox> Last Name <textbox>, Details of person 2: First Name<textbox etc..."
View 3: "Please review and confirm the details are correct:" Displays data entered in view 2.
Here's the difficult part - In order to generate the controls in view 2, I need to know the value of the text box in view 1. This value isn't available during Page_Init as viewstate has not yet been written. But - need to build the controls during Page_Innit. So - I thought why not try to grab the value of the textbox using Request.Form[Texbox1.ClientID]; - this is fine when moving from view1 to view2 but remember - I need to recreate these controls again if the user moves back to view1 or forward to view3 (it is a requirement that the user can move backwards and forwards between the views).
So - User enters value in Textbox in View1, hits the "Next button", we request that value using Request.Form and generate a series of controls dynamically. Then the user clicks "Next" again and moves to view 3 where we would like to show a summary of what they entered. But - we cant because those controls dont exist as we could not create them because the value of textbox1 is not available during Page_Init and we can't use Request.Form as the textbox isn't now part of request.form because we came from view2, not view1.
I can't figure out how to dynamically create these controls and then recreate them during page_innit on each postback so we retain any values the user might have entered.

I've recently added a Master Page to my site,but realized that it's caused some problems in my existing JavaScript setup.I am able to use the following code in most places without any issue to get the ClientID: '<%=myControl.ClientID%>'
The problem I have encountere is that I have several pages that add controls dynamically,and then execute events based on an ID that's passed in,where I can't use this line,because I won't know the ID of the control I'm trying to access until the Javascript executes.Here's a simplified version of the problem:
When the page runs,it creates n textboxes dynamically,and appends a relevant ID from the database to the end of the ID.Let's say the page has added 3 textboxes with the following IDs:
myTextBox1
myTextBox7
myTextBox115
Later,a javascript event fires,and I need to be able to access the control through JavaScript like this:
myJavaScriptFunction (controlID)
{
myvar = document.getElementById('myTextBox' + controlID);
}
