I wish I could go all the elements of an ASP.Net page (HTML elements) and manipulate its text property / value. How could I do that?
I've been checking, and the property this.Page.Form.Controls apparently gets all the elements, but I would only page elements that caught the event.
I'll put an example of code that I'm currently studying and trying adpater for my needs.

I'm new to AJAX/javascript, and I'm not sure what the best approach is for what I'm trying to do.
I'm calling page methods (WebMethods) on my Page using Javascript. The data I'm retrieving is a list of Divs basically.
I don't know how many will be returned, but they need to be inserted into the proper place on the page depending on their content.
I see a couple ways of doing this:
Create a list of HtmlGenericControls and pass them back. Create a list of Strings, where each String is the entire Div code I want to drop onto the page. (This feels wrong for some reason)Create simple container objects that have the necessary data in them. Pass those to the page and use them to create the Divs within javascript.
I currently have a GridView control on my aspx page with paging enabled and I need to loop through the entire row collection/count to process the selected records. With my current code, it will only loop through the current page of GridView row.
foreach (GridViewRow data in grid.Rows)
{
//here is my code
}

I'm scraping a page from a remote site. I have the correct HTML and it is below. However, I need to display only the top 3 new stories. Using C# how can I loop through the HMTL on the page to do this? Here is the HTML that I have scraped from the screen and am currently display on the page:

I am looking for a way to figure out the current URL that the page is currently on (NOT what the asp.net page currently is, but where the CODE is at). ie. My web app is located at: [URL] my code is: String page = [URL]
String response = GetResponse(page); //basically the above code goes to the website [URL] and parses the HTML within it and brings it back and populates the variable string "response". But, sometimes the [URL] throws me a curve ball and redirects me to: [URL] I want to be able to use a try/catch to be able to "catch" the error of a different page: ie validateUser.aspx. So, I need to do to this: try
{
String page = [URL];
String response = GetResponse(page);
}
catch
{
//code to check the behind URL to see if [URL] is the URL OR IF [URL] is the current URL
}
understand I know how to find the URL of the current page the web app is on. I need to find the current page that threw the exception during the execution of the code behind.
How can I loop through table and row that have an attribute id or name to get inner text in deep down in each td cell? I work on asp.net, c#, and the newest html agility package.
An html file have several tables. One of them has an attribute id=main-part. In that identified table, there are many rows. Some of those rows have same attribute name=display. In those named rows, there are many columns which I have to extract text from. Something like this:
<body>
<table>
</table>
<table>

I have a question about asp.net
I have this table with checkbox for each row:
[URL]
table code inside the ASPX page:
[URL]
So I'm trying to implement the delete selected button.. How exactly do i point to the specific checkbox for a particular row from codebehind when all 3 have the same name chkSelected? I know how to do it with a gridview, but not quite sure how if we do it with a for loop..
Can I do something like this inside btnDelete_Click?

I am building in error-logging into my site, and want to be able to get hold of the current page name that the error occurred in, as well as the specific subroutine or function, to then pass to a VB.NET function. Is there anyway to get hold of this information without hard-coding the names manually? For example,
Dim strCurrentPageName = ???
Dim strCurrentRoutine = ???
I have a report that I generate with HTML.
I'd like to get the HTML output of the page, and be able to send it via email. I'm having problem with session, because the report redirect me to the login page because when I create a new WebRequest, it doesn't use the information of the current session.
Is there a way to get the HTML of the report without having to code a work-around for the security ?
I am currently working on a ASP.net web app which the user enters info into input boxes and selects items from dropdowns. Once the user is finished they click on a button which validates the fields (using jquery validate plugin) and then removes the fields and replaces them with only field value. So essentially there are no more input fields only text.
The next step is to click on a button which will convert the html to pdf. However, when I do this, the PDF that is generated has all of the input fields that I previously removed. When I debug, I notice the HTML being returned is still the old HTML and when I view the page source, I am still seeing the old HTML even though the browser is showing the changes.
I am using this to grab the current html after the button click:
string htmlCode;
WebClient wb =
new
WebClient();
htmlCode = wb.DownloadString(devurl);
I've seen this error explained on multiple sites, however, none of the fixes works for me. I have this line of code:
[Code]....
Still I'm out of luck. I've tried reinstalling Asp.Net MVC 2 RC and recreating the reference System.Web.Mvc.
I must be missing something simple here. This code was working and i can't seem to figure out why it stopped.
First, I generate a selectlist in the controller like this:
// Select List
ViewData["FieldTypesList"] = new SelectList(
genesisRepository.FieldTypes, "ftID", "ftName"
);
The View that uses this select list looks like this:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Genesis.Domain.Entities.Stream2FieldTypes>" %>
<%@ Import Namespace="Genesis.Domain.Entities" %>
<%: Html.DropDownListFor(
model => model.FieldTypeID,
(SelectList)ViewData["FieldTypesList"]
)%>
<%:Model.FieldTypeID.ToString() %>
However... the HTML that gets generated shows this:
<select id="Stream2FieldTypes_0_" name="Stream2FieldTypes[0]"><option value="1">Text Area</option>
<option value="2">Text Box</option>
<option value="3">Rich Text</option>
<option value="4">Image</option>
<option value="5">DateTime</option>
<option value="6">Decimal</option>
<option value="7">Integer</option>
</select>
3 <!--FYI: current value-->
I am completely missing why the view does not render html that selects 3 (Rich Text).

I have a legacy ASP application which - at some point soon - needs to be migrated to ASP.Net 2.0 (to be compatible with other apps that are also in 2.0). Are there best practices for this sort of thing i.e. is it possible/advisable as a first step to transfer the current unholy mix of html, vbscript and javascript en masse to aspx pages (without any code-behind separation), and then iteratively replace vbscript with data sources and the like, or this more trouble than its worth? [The app is not that complex (we are talking 10 or so .asp pages, with a similar number of .inc files), but the mix of html and scripts is not at all pretty: lots of if-else statements to build SQL commands etc.].

Per different user mode, some pages should not be accessible by users unless they have a valid session key.In your opinions -- would it be better to have a list of acceptable pages in the master page, and check if the current page is valid for the current user? Or handle this on every child page?I'm thinking master page, just want to hear what your input would be.
