I am showing data from different databases in a web part. Would it be possible to dynamically add and remove that data including the layout that that <DIV> has and would I go about in doing this?

I am converting a web forms site to MVC and there are a lot of pages all with an individual screenshot image on. Rather than have a separate page for each screenshot image, I though a better way to do this would be to have one page, and to pass the image details into a Controller method, and then set the src value of the <img> in my code. Does anybody know how to do this, and even if it is a good idea to be making reference to UI elements in my Controller code?

Im using VS 2008 and have created a Visual C# ASP.Net Web Application and have a Table on the Page (Created at Design Time).
Im Trying to add rows at runtime when the user presses a button but it creates one row then none after.

to duplicate an already existing <div> with its existing controls multiple times on one form. I have a situation where I have a group of controls contained in one <div>, but the user might need to add more information in the same format so I would like to just have them click a button to add another component and the same set of controls will be duplicated below it.
View 6 RepliesIn my Page_Load() event, I'm calling a Sub (in a module UserMenu.vb) that reads an XML file which has the user menu entries. The final menu should be an <ul> with several <li>, some of them with anidated <ul> within. As I understand, I may use a asp:Panel in my page to position a container for this elements I read and in this sub I try to add them using new BulletedList and new ListElement BList.Items.Add(LItem)), but when I get to Panel.Controls.Add(BList) it throws an error that says BList should be inserted in a Form. Why? Aren't they just <ul> and <li>? What other alternative I have to create <ul> and <li> in a specific part of my page?
View 3 RepliesI am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?
I need to have a siteMapeNode for a menu control to only show up during development.
The following node would be in the web.sitemap file.

I can either put this node in my web.sitemap file and remove it in release builds.
Or Add the node in debug builds.
Probably done in PreInit or Page_load events.
I'm trying to add some user controls on a page. Thats easy, I just do it like this.
UserControl block = (categoryblock) LoadControl("categoryblock.ascx");
Panel1.Controls.Add(block);
But i want to access the label controls and more that are inside the categoryblock.ascx. How would i do that? I cant do it like this,
block.l_itemName.text = "blabla";
I managed to user FindControl("l_itemName") but i would rather like to have the intellisense.
I'd like to add a control A (that exists on a page) to a Footer user control's panel. If I create the control A dynamically and add it, I don't have issues. But I would like to avoid adding this dynamically.So, I defined control A in the aspx page and in the code behind, I got reference to the footer's panel and did a Controls.Add() It works fine, but postbacks from this control has strange behavior (could be due to viewstate?) as it doesn't execute some code that is on the page with a !IsPostback condition

View 4 RepliesI am working in asp.net MVC & on the view has to show both json & xml content depending on some condition.
I have to change the content type of the page at runtime ie,
if the condition for json is fulfilled then set page contenttype = "text/json"
&
if the condition for xml is fulfilled then set page contenttype = "text/xml".
I have tried setting default content type on view as
<%
@
Page
Language="C#"
Inherits="System.Web.Mvc.ViewPage"
ContentType="text/json"%>
& in controller class if xml condition is fulfilled then chnage it like :
this.Response.Clear;
this.Response.ContentType = "text/xml";
BUT it didn't work for me .
I have have two radio button lists that need to be mutally exculisve, i.e when one is clicked the other one neesd to be cleared, my further problem is beause they are in a formview I had to add handlers to clear all the controls in the other list when the one is clicked and vice versa. here is the code below Now the code works but one of the testers found that if you click back and forth around twenty times you get the above java error:
Exception message: Maximum request length exceeded
my though here is the handler is being added to many times ? but even if I remove the handler after the process is complete I still get the same error.

I am trying to add a radio button click event at runtime.
Radiobutton button = new RadioButton();

I know I can do this from the markup, but when I try to do this from the code behine, I cant find OnCheckedChanged.
How do you add a PayPal button inside of a content detail of a master page. Since a MasterPage automatically encapsulates and nests ALL of the code of its contentplaceholder, by definition...all design and coding in a contentplaceholder cannot encorporate a form. This is true because w3 specs do not allow the nesting for forms.

This error comes up when adding a content page to a website. Is there something that I need to add somewhere?

View 2 RepliesWe have a web application written in ASP.NET for .NET 3.5, using standard web forms.
Going forward we want to start building new features, and over time migrate existing features, in ASP.NET MVC.
Is such a thing doable? Can we add the necessary files to an ASP.NET web application and thus "upgrade" it to be compatible enough with MVC so that we can start adding routes, controllers, views, etc.?
The old site is using a frameset containing a top header, a left menu, and a main content. What I envisioned was to create a new masterpage for all the existing pages, integrating all of those things into each page instead, and then start adding new pages using views instead.
I understand that unless we upgrade to .NET 4 we cannot use MVC 3, so the way I see it we have the following options:
Build a new website, somehow auto logon the new site with the same credentials when logging in on the main site, and link between the sites. I see tons of problems with this solution. Integrate ASP.NET MVC 2 into the existing software, adding the necessary files, and starting to add new content in MVC style, only fixing critical bugs in the old files, and over time migrate them over to MVC. Upgrade to .NET 4 and integrate ASP.NET MVC 3, pretty much the rest the same as option 2. Wait until we can schedule a full rewrite, likely to not happen in any foreseeable future. Don't do it, keep web forms.
Note that a full rewrite is out of scope at the moment, so some transitional period is the only option we can do right now.
Option 2 and 3 are the ones we want, the rest are just for completeness.
I programatically add meta tags to the head of each page using htmlhead, specifying the name and content. I now need to add new meta tags with property and content.

View 5 RepliesI got an updatepanel which contains a normal panel on MasterPage. The updatepanel does not contain content place holder. On the content page, I have to add triggers to updatepanel for buttons that are dynamically created on "page_load" event. The problem is that, since the page_load event of content page is being called before master page's page_load event, UpdatePanel is not being created. So that, whenever i try to add triggers in page_load event of content page, i got an error like "A control with ID 'ctl00$editableContent$ctl42' could not be found for the trigger in UpdatePanel 'up1'."
The code below is for adding triggers to updatepanel for buttons.
MasterClass master = (MasterClass)Page.Master;
AsyncPostBackTrigger trig = new AsyncPostBackTrigger(); [code]....
I would like to use the OpenID selector found here The problem is that i would like to use it in a content page, which is child of a master page.
So what modifications should i make?
I mean my master page contains the form already
<form id="form1" runat="server">
...
</form>
but so does the OpenID selector page
<form class="openid" method="post" action="/Login.xhtml?ReturnUrl=">
</form>
together with post and ReturnUrl... which is something that i need only in the login page... Right?
