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 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:

I'm using this Ajax script [URL] to load content from an aspx page on another server than the page calling the content. So far I've learned that this is a no go. The problem seems to be that when using an absolute link to content the script fails as apposed to using a relative link.
I've searched the web for about 10 hours now, and I still haven't found what I'm looking for.
which page need to be checked. Master or Content. I dont think there is anything wrong in the content page.

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 am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.

How to I put this form on my page? The problem is I have a master page which wraps the content pages content in the ASP.net form, I can't nest the forms.
how can i add title and meta tags for content pages in a project base on master and content page(dinamically) ?
i used the blow method for master page :

how to get this code inline instead?

I have 2 masterfiles which are the TopMasterPage and SideMaterpage masterpage. I need to change the div content at the master page after logging into the page from the content page.
TopMasterPage (Div control in this master page)
---------------
SideMaterpage
---------------------------
ContentPage -- (Update content to the Div Control)
I include runat="Server" but fail.
My content page looks like this:
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Basket.aspx.cs" Inherits="Basket" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
</asp:Content>
Now, I would like to add some controls dynamically to the content when page loads, so I am trying the following code:
protected void Page_Load(object sender, EventArgs e)
{
Content2. // I want to add controls to it dynamically
}
The problem is that the Content2 control is not visible by the compiler and I am getting error about missing directive or assembly reference.
in my updatePanle have 5 controls
RadioButton1 TextBox1 TextBox2
RadioButton2 TextBox3
I use javascript to change TextBoxes's Status each time RadioButton.onClick
now I want to force controls in UpdatePanel render again eachtime RadioButton clicked..
I add _doPostback to my javascript..
the result is not ok... because I lost the value after page render again
for example,user fill in these value to controls
RadioButton1 (Checked) TextBox1 (Text= 90 , Style = "AA") TextBox2 (Text=30 style="BB")
RadioButton2 TextBox3
then user change controls like this
RadioButton1 TextBox1 (Text= 90) TextBox2 (Text=30)
RadioButton2 (Checked) TextBox3
I want to force controls render again but keep the value and style .
I have a question that I can't quite find the answer to...
If you have an ASP.Net page that takes longer than the request time-out to render what happens to that process? Does the web service abort it?
Lets say I'm writing XML to the response stream in an ASP.Net page and it times-out calling my GenerateXML method. What happens to my method call? Does it complete but the web server reports the time out? or is it aborted?
I could probably write a test to see my own results but I figure there might be more to it.
I want to check render time of each page in asp.net mvc application.
i am using asp.net tracing. i have override the OnActionExecuting and OnActionExecuted methods on the BaseController class.
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
string controler = filterContext.RouteData.Values["controller"].ToString();
string action = filterContext.RouteData.Values["action"].ToString();
StartTime =System.DateTime.Now;
System.Diagnostics.Trace.Write(string.Format("Start '{0}/{1}' on: {2}", controler, action, System.DateTime.Now.UtilToISOFormat()));
}
protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
string controler = filterContext.RouteData.Values["controller"].ToString();
string action = filterContext.RouteData.Values["action"].ToString();
var totalTime = System.DateTime.Now - this.StartTime;
System.Diagnostics.Trace.Write(totalTime.ToString());
System.Diagnostics.Trace.Write(string.Format("End '{0}/{1}' on: {2}", controler, action, System.DateTime.Now.UtilToISOFormat()));
}
in OnActionExecuted method i get total time. how can i show this time in my http://localhost:51335/Trace.axd report?
Even i had set Trace="true" in <%@ Page %> on every page also.
I have an application that runs perfectly fine and fast in IE 7. There are certain pages in the application that use the AlwaysVisibleExtender control.
However, when I run the app in IE 8, the same exact pages seem to lock up for roughly 5 seconds before they render completely. What's weird is that the page shows all the contents except for the alwaysvisibleextender and relating panel. Then after the 5 seconds the panel shows. During that 5 seconds the page cannot be navigated or scrolled. This is not really acceptable.
Letīs take an usual aspx page, ~/admin/template.aspx
The admin folder allows only "Admin" roles for example.
Now I donīt want to run the template.aspx as usual, but I want it be called from a active process. Letīs say Iīm on ~/admin/buildMyStuff.aspx and there Iīm collecting some data, I now have some querystring, like "?do=this$andDo=that$index={0}". Now I want, using this template, loop through my data and generate my ouput, putting it then for example in a static html or in a text file or something else.
How should I do that? Calling it as new request, waiting for response? What I have to do, that it is running under the "Admin" role, or is it doing it automatically, since I already am admin?
Or is there another possibility, that allows me to run the template page and specifiing my custom htmltextwriter as output?
EDIT:
public static string RenderPageAndGetHtml(string pageUrl, string pageQuery)
{
var sw = new StringWriter();
var wr = new SimpleWorkerRequest(pageUrl, pageQuery, sw);
